Abstract
INTRODUCTION Conservative treatment of acute appendicitis is gaining popularity, and identifying patients with a higher risk of recurrence is becoming increasingly important. Previous studies have suggested that older age, male sex, diabetes, appendicolith and abscess formation may be contributing factors, however, results from the adult population are inconsistent. AIM This study aims to identify predictive factors for recurrent appendicitis after conservative treatment. METHODS This retrospective study included patients with conservatively treated acute appendicitis at Skåne University Hospital, Sweden during 2012-2019. Information on patient demographics at index admission and follow-up data were retrieved from medical charts and radiologic images. Uni -and multivariable logistic regression analysis were performed using Stata Statistical Software. RESULTS In total, 379 patients with conservatively treated acute appendicitis were identified, of which 78 (20.6%) had recurrence. All patients were followed-up for a minimum of 41 months after the first diagnosis of acute appendicitis unless appendectomy after successful conservative treatment or death occurred during follow-up. The median time to recurrence was 6.5 (1-17.8) months. After multivariable logistic regression analysis, external appendix diameter >10 mm [OR 2.4 (CI 1.37-4.21), p = .002] and intra-abdominal abscess [OR 2.05 (CI 1.18-3.56), p = .011] on computed tomography were significant independent risk factors for recurrent appendicitis. Appendicolith was not associated with an increased risk of recurrence. CONCLUSION This study suggests abscess formation and appendix distension of >10 mm to be potential risk factors for recurrent acute appendicitis after initial successful conservative treatment.

Abstract
Acute appendicitis is a typical surgical emergency worldwide and one of the common causes of surgical acute abdomen in the elderly. Accurately diagnosing and differentiating acute appendicitis can assist clinicians in formulating a scientific and reasonable treatment plan and providing high-quality medical services for the elderly. In this study, we validated and analyzed the different performances of various machine learning models based on the analysis of clinical data, so as to construct a simple, fast, and accurate estimation method for the diagnosis of early acute appendicitis. The dataset of this paper was obtained from the medical data of elderly patients with acute appendicitis attending the First Affiliated Hospital of Anhui University of Chinese Medicine from January 2012 to January 2022, including 196 males (60.87%) and 126 females (39.13%), including 103 (31.99%) patients with complicated appendicitis and 219 (68.01%) patients with uncomplicated appendicitis. By comparing and analyzing the prediction results of the models implemented by nine different machine learning techniques (LR, CART, RF, SVM, Bayes, KNN, NN, FDA, and GBM), we found that the GBM algorithm gave the optimal results and that sensitivity, specificity, PPV, NPV, precision, recall, F1 and brier are 0.9167, 0.9739, 0.9429, 0.9613, 0.9429, 0.9167, 0.9296, and 0.05649, respectively. The GBM model prediction results are interpreted using the SHAP technology framework. Calibration and Decision curve analysis also show that the machine learning model proposed in this paper has some clinical and economic benefits. Finally, we developed the Shiny application for complicated appendicitis diagnosis to assist clinicians in quickly and effectively recognizing patients with complicated appendicitis (CA) and uncomplicated appendicitis (UA), and to formulate a more reasonable and scientific clinical plan for acute appendicitis patient population promptly.

Three-Year Outcomes of Oral Antibiotics vs Intravenous and Oral Antibiotics for Uncomplicated Acute Appendicitis: A Secondary Analysis of the APPAC II Randomized Clinical Trial. JAMA Surg 2024; 159:727-735. [PMID: 38630471 PMCID: PMC11024776 DOI: 10.1001/jamasurg.2023.5947] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 08/27/2023] [Indexed: 04/20/2024]
Abstract
Importance Current short-term evidence has shown that uncomplicated acute appendicitis can be treated successfully with oral antibiotics alone, but longer-term results are lacking. Objective To assess the treatment effectiveness of oral antibiotic monotherapy compared with combined intravenous (IV) and oral antibiotics in computed tomography-confirmed uncomplicated acute appendicitis at a longer-term follow-up. Design, Setting, and Participants This secondary analysis of a predefined year 3 follow-up of the Appendicitis Acuta II (APPAC II) noninferiority, multicenter randomized clinical trial compared oral moxifloxacin with combined IV ertapenem plus oral levofloxacin and metronidazole for the treatment of uncomplicated acute appendicitis. The trial was conducted at 9 university and central hospitals in Finland from April 2017 to November 2018, with the last follow-up in November 2022. Participants included patients aged 18 to 60 years, who were randomized to receive either oral antibiotics monotherapy (n = 301) or combined IV and oral antibiotics (n = 298). Interventions Antibiotics monotherapy consisted of oral moxifloxacin, 400 mg/d, for 7 days. Combined IV and oral antibiotics consisted of IV ertapenem sodium, 1 g/d, for 2 days plus oral levofloxacin, 500 mg/d, and metronidazole, 500 mg 3 times/d, for 5 days. Main Outcomes and Measures The primary end point was treatment success, defined as the resolution of acute appendicitis and discharge from hospital without the need for surgical intervention and no appendicitis recurrence at the year 3 follow-up evaluated using a noninferiority design. The secondary end points included late (after 1 year) appendicitis recurrence as well as treatment-related adverse events, quality of life, length of hospital stay, and length of sick leave, which were evaluated using a superiority design. Results After exclusions, 599 patients (mean [SD] age, 36 [12] years; 336 males [56.1%]) were randomized; after withdrawal and loss to follow-up, 582 patients (99.8%) were available for the year 3 follow-up. The treatment success at year 3 was 63.4% (1-sided 95% CI, 58.8% to ∞) in the oral antibiotic monotherapy group and 65.2% (1-sided 95% CI, 60.5% to ∞) in the combined IV and oral antibiotics group. The difference in treatment success rate between the groups at year 3 was -1.8 percentage points (1-sided 95% CI, -8.3 percentage points to ∞; P = .14 for noninferiority), with the CI limit exceeding the noninferiority margin. There were no significant differences between groups in treatment-related adverse events, quality of life, length of hospital stay, or length of sick leave. Conclusions and Relevance This secondary analysis of the APPAC II trial found a slightly higher appendectomy rate in patients who received oral antibiotic monotherapy; however, noninferiority of oral antibiotic monotherapy compared with combined IV and oral antibiotics could not be demonstrated. The results encourage future studies to assess oral antibiotic monotherapy as a viable treatment alternative for uncomplicated acute appendicitis. Trial Registration ClinicalTrials.gov Identifier: NCT03236961.

Management of intra-abdominal infections: recommendations by the Italian council for the optimization of antimicrobial use. World J Emerg Surg 2024; 19:23. [PMID: 38851757 PMCID: PMC11162065 DOI: 10.1186/s13017-024-00551-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Accepted: 06/01/2024] [Indexed: 06/10/2024] Open
Abstract
Intra-abdominal infections (IAIs) are common surgical emergencies and are an important cause of morbidity and mortality in hospital settings, particularly if poorly managed. The cornerstones of effective IAIs management include early diagnosis, adequate source control, appropriate antimicrobial therapy, and early physiologic stabilization using intravenous fluids and vasopressor agents in critically ill patients. Adequate empiric antimicrobial therapy in patients with IAIs is of paramount importance because inappropriate antimicrobial therapy is associated with poor outcomes. Optimizing antimicrobial prescriptions improves treatment effectiveness, increases patients' safety, and minimizes the risk of opportunistic infections (such as Clostridioides difficile) and antimicrobial resistance selection. The growing emergence of multi-drug resistant organisms has caused an impending crisis with alarming implications, especially regarding Gram-negative bacteria. The Multidisciplinary and Intersociety Italian Council for the Optimization of Antimicrobial Use promoted a consensus conference on the antimicrobial management of IAIs, including emergency medicine specialists, radiologists, surgeons, intensivists, infectious disease specialists, clinical pharmacologists, hospital pharmacists, microbiologists and public health specialists. Relevant clinical questions were constructed by the Organizational Committee in order to investigate the topic. The expert panel produced recommendation statements based on the best scientific evidence from PubMed and EMBASE Library and experts' opinions. The statements were planned and graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) hierarchy of evidence. On November 10, 2023, the experts met in Mestre (Italy) to debate the statements. After the approval of the statements, the expert panel met via email and virtual meetings to prepare and revise the definitive document. This document represents the executive summary of the consensus conference and comprises three sections. The first section focuses on the general principles of diagnosis and treatment of IAIs. The second section provides twenty-three evidence-based recommendations for the antimicrobial therapy of IAIs. The third section presents eight clinical diagnostic-therapeutic pathways for the most common IAIs. The document has been endorsed by the Italian Society of Surgery.

Abstract
Intra-abdominal infections (IAIs) are an important cause of morbidity and mortality in hospital settings worldwide. The cornerstones of IAI management include rapid, accurate diagnostics; timely, adequate source control; appropriate, short-duration antimicrobial therapy administered according to the principles of pharmacokinetics/pharmacodynamics and antimicrobial stewardship; and hemodynamic and organ functional support with intravenous fluid and adjunctive vasopressor agents for critical illness (sepsis/organ dysfunction or septic shock after correction of hypovolemia). In patients with IAIs, a personalized approach is crucial to optimize outcomes and should be based on multiple aspects that require careful clinical assessment. The anatomic extent of infection, the presumed pathogens involved and risk factors for antimicrobial resistance, the origin and extent of the infection, the patient's clinical condition, and the host's immune status should be assessed continuously to optimize the management of patients with complicated IAIs.

[PMID: 38640616 DOI: 10.1016/j.jss.2024.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 02/08/2024] [Accepted: 03/17/2024] [Indexed: 04/21/2024]
Abstract
INTRODUCTION Nonoperative management (NOM) of uncomplicated appendicitis (UA) has been increasingly utilized in recent years. The aim of this study was to describe nationwide trends of sociodemographic characteristics, outcomes, and costs of patients undergoing medical versus surgical management for UA. METHODS The 2018-2019 National (Nationwide) Inpatient Sample was queried for adults (age ≥18 y) with UA; diagnosis, as well as laparoscopic and open appendectomy, were defined by the International Classification of Diseases, 10th Revision, Clinical Modification codes. We examined several characteristics, including cost of care and length of hospital stay. RESULTS Among the 167,125 patients with UA, 137,644 (82.4%) underwent operative management and 29,481 (17.6%) underwent NOM. In bivariate analysis, we found that patients who had NOM were older (53 versus 43 y, P < 0.001) and more likely to have Medicare (33.6% versus 16.1%, P < 0.001), with higher prevalence of comorbidities such as diabetes (7.8% versus 5.5%, P < 0.001). The majority of NOM patients were treated at urban teaching hospitals (74.5% versus 66.3%, P < 0.001). They had longer LOS's (5.4 versus 2.3 d, P < 0.001) with higher inpatient costs ($15,584 versus $11,559, P < 0.001) than those who had an appendectomy. Through logistic regression we found that older patients had up to 4.03-times greater odds of undergoing NOM (95% CI: 3.22-5.05, P < 0.001). CONCLUSIONS NOM of UA is more commonly utilized in patients with comorbidities, older age, and those treated in teaching hospitals. This may, however, come at the price of longer length of stay and higher costs. Further guidelines need to be developed to clearly delineate which patients could benefit from NOM.

Bendib H. Is non-operative treatment of acute appendicitis possible: A narrative review. Afr J Emerg Med 2024; 14:84-90. [PMID: 38617036 PMCID: PMC11010839 DOI: 10.1016/j.afjem.2024.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 03/19/2024] [Accepted: 03/28/2024] [Indexed: 04/16/2024] Open
Abstract
Introduction Acute appendicitis (AA) represents the most frequent surgical emergency. Perforation was long considered the ultimate outcome of AA, prompting appendectomy; which remains the standard treatment. New data have clarified the role of the appendix, justifying conservative treatment. This narrative review aims to summarize the evidence regarding the non-operative treatment (NOT) of AA in adults. Methods The literature search was performed via the PubMed Medline database. Our criteria-based selection resulted in a total of 48 articles for review. Results Recent trials and meta-analyses have assessed NOT, which support primary antibiotic treatment of uncomplicated AA. Although it has a significant recurrence and failure rate, NOT does not appear to increase the risk of appendicular perforation. Moreover, NOT compared with appendectomy, seems to be associated with less morbidity, lower cost of care and preserved quality of life. Conclusion First-line NOT seems to be a reasonable approach for the treatment of uncomplicated CT-confirmed AA. Careful patient screening would definitely enhance the success rate.

Abstract
Despite being the most common abdominal surgical emergency, the cause of acute appendicitis (AA) remains unclear, since in recent decades little progress has been made regarding its etiology. Obstruction of the appendicular lumen has been traditionally presented as the initial event of AA; however, this is often the exception rather than the rule, as experimental data suggest that obstruction is not an important causal factor in AA, despite possibly occurring as a consequence of the inflammatory process. Type I hypersensitivity reaction has been extensively studied, involving Th2 lymphocytes, and cytokines such as IL-4, IL-5, IL-9 and IL-13, which have well-defined functions, such as a positive-feedback effect on Th0 for differentiating into Th2 cells, recruitment of eosinophils and the release of eosinophilic proteins and the production of IgE with the activation of mast cells, with the release of proteins from their granules. Cytotoxic activity and tissue damage will be responsible for the clinical manifestation of the allergy. AA histological features are similar to those found in allergic reactions like asthma. The intestine has all the components for an allergic immune response. It has contact with hundreds of antigens daily, most of them harmless, but some can potentially induce an allergic response. In recent years, researchers have been trying to assess if allergy is a component of AA, with their latest advances in the understanding of AA as a Th2 reaction shown by the authors of this article.

[PMID: 38218686 DOI: 10.1016/j.surg.2023.11.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 11/21/2023] [Accepted: 11/27/2023] [Indexed: 01/15/2024]
Abstract
BACKGROUND Antibiotic treatment of unselected patients with acute appendicitis is safe and effective. However, it is unknown to what extent early provision of antibiotic treatment may represent overtreatment due to spontaneous healing of appendix inflammation. The aim of the present study was to evaluate the role of antibiotic treatment versus active in-hospital observation on spontaneous regression of acute appendicitis. METHOD Patients who sought acute medical care at Sahlgrenska University Hospital were block-randomized according to age (18-60 years) and systemic inflammation (C-reactive protein <60 mg/L, white blood cell <13,000/μL), in combination with clinical and abdominal characteristics of acute appendicitis. Study patients received antibiotic treatment and active observation, while control patients were allocated to classic active "wait and see observation" for either disease regression or the need for surgical exploration. According to our standard surgical care, certified surgeons in charge decided whether and when appendectomy was necessary. In total, 1,019 patients were screened for eligibility; 203 patients met inclusion criteria, 126 were accepted to participate, 29 declined, and 48 were missed for inclusion. RESULTS The antibiotic group (n = 69) and the control group (n = 57) were comparable at inclusion. Appendectomy at first hospital stay was 28% and 53% for study and control patients (χ2, P < .004). Life table analysis indicated a time-dependent difference in the need for appendectomy during follow-up (P < .03). Antibiotics prevented surgical exploration and appendectomy by 72% to 50% compared to 47% to 37% in the control group across the time course follow-ups between 5 and 1,200 days. CONCLUSION Early antibiotic treatment is superior to traditional "wait and see observation" to avoid surgical exploration and appendectomy.

The Association Between C-Reactive Protein Levels and Pediatric Appendicitis Score and the Severity of Appendicitis in Children. J Emerg Med 2024; 66:e508-e515. [PMID: 38429214 DOI: 10.1016/j.jemermed.2023.11.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 11/18/2023] [Accepted: 11/23/2023] [Indexed: 03/03/2024]
Abstract
BACKGROUND Acute appendicitis is a common cause of abdominal pain leading to emergent abdominal surgery in children. C-reactive protein (CRP), an inflammatory marker typically elevated in acute appendicitis, and Pediatric Appendicitis Score (PAS), a clinical scoring system used for the diagnosis of appendicitis, have the potential to predict the severity of inflammation of the appendix. This may be useful in helping the physician make a treatment plan prior to surgery. OBJECTIVE The purpose of this study was to assess whether CRP value and PAS differ with the extent of inflammation of the appendix seen on histologic examination. METHODS This was a prospective observational study of patients diagnosed with acute appendicitis via computed tomography or ultrasound. Enrolled patients had CRP levels drawn, PAS calculated, and appendix pathology reviewed. Appendix pathology was categorized by the pathologist on the basis of the level of inflammation: simple, suppurative, gangrenous, and perforated. RESULTS One hundred sixty-three patients were enrolled. CRP levels and PAS were statistically different (p < 0.002) among the four pathology classifications. Patients with simple appendicitis (n = 3) had a mean CRP of 2.95 mg/L and PAS of 3.9, patients with suppurative appendicitis (n = 99) had a mean CRP of 26.89 mg/L and PAS of 6.5, patients with gangrenous appendicitis (n = 56) had a mean CRP of 91.11 mg/L and PAS of 7.5, and patients with perforated appendicitis (n = 6) had a mean CRP of 154.17 mg/L and PAS of 7. The results remained statistically significant (p < 0.002) after adjusting for age, race, and sex. When combined-PAS ≥ 8 and CRP level > 40 mg/L-the specificity of complicated appendicitis was 91.2% and positive predictive value was 72.7%. CONCLUSIONS Higher CRP levels and PAS were associated with increased histologic inflammation of the appendix. This study provides preliminary evidence that CRP and PAS could potentially assist in treatment decisions for appendicitis.

CT of appendicoliths in adult appendicitis: clinical significance and characteristics of overlooked cases. Eur Radiol 2024; 34:2534-2545. [PMID: 37837538 PMCID: PMC10957675 DOI: 10.1007/s00330-023-10273-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 08/02/2023] [Accepted: 08/09/2023] [Indexed: 10/16/2023]
Abstract
OBJECTIVES Accurate computed tomography (CT) identification of appendicoliths in adults with acute appendicitis is crucial as it may preclude nonoperative management due to high risk of failure and complications. This investigation aimed to identify the significance of appendicoliths in acute appendicitis and to evaluate the performance of portovenous-phase (PVP) CT and the consequences of overlooked appendicoliths. METHODS CT examinations of 324 consecutive patients (mean age 51.9 years, 112 men) with pathologically confirmed acute appendicitis were retrospectively included. Two radiologists independently reviewed the images, and disagreement was resolved by a consensus. RESULTS Appendicoliths were identified in 134/324 patients, of which 75 had complicated appendicitis. Among 190 patients without appendicoliths, 52 had complicated appendicitis. An appendicolith was independently associated with complicated appendicitis (adjusted odds ratio 2.289; 95% CI: 1.343-3.902; p = 0.002). The larger minimum diameter was significantly associated with complication. The 4.5-/6.0-mm cutoffs for minimum and maximum diameters of appendicoliths demonstrated 82.7%/85.3% sensitivity and 35.6%/33.9% specificity in predicting complications. The PVP alone had 82.1-88.1% sensitivity, respectively per patient and per appendicolith, and a 100% specificity in the detection of appendicoliths, as compared with combined noncontrast and PVP. PVP overlooked 28/237 appendicoliths (11.8%) corresponding to 24/134 patients (17.9%). Of the 24 patients with overlooked appendicoliths, 16 had complicated appendicitis but 14 were correctly categorized by findings other than appendicoliths. In total, 2/127 patients (1.6%) with complicated appendicitis were misdiagnosed as having uncomplicated appendicitis. CONCLUSIONS Appendicoliths in acute appendicitis were strongly associated with complications. While PVP overlooked some appendicoliths, only 1.6% of complicated appendicitis were misclassified when considering other CT findings. CLINICAL RELEVANCE STATEMENT This study found a strong association between appendicoliths and complications. Its presence may preclude conservative management. Although portovenous-phase CT overlooked some appendicoliths, the combination with other CT findings allowed correct classification in a vast majority of cases. KEY POINTS • Accurate identification of appendicoliths is crucial for nonoperative management decisions in adult acute appendicitis. • Appendicoliths are strongly associated with complications in adult acute appendicitis. • Portovenous-phase CT overlooked some appendicoliths, but only a small percentage of patients with complicated appendicitis were misclassified when considering other CT findings.

Abstract
This study aimed to comprehensively evaluate the effects of evidence-based nursing (EBN) intervention on wound infection and postoperative complications in patients after appendectomy for acute appendicitis (AA), with the expectation of providing a theoretical basis for postoperative care in AA. Randomised controlled trials (RCTs) on the postoperative application of EBN in patients with AA were searched in PubMed, Web of Science, Cochrane Library, Embase, China Biomedical Literature Database, Wanfang and China National Knowledge Infrastructure from the inception of databases to October 2023. Two authors screened and evaluated the literature based on the inclusion and exclusion criteria, and data were extracted from the final included literature. Stata software (version 17.0) was employed for data analysis. In total, 29 RCTs involving 2848 patients with AA were included, with 1424 in the EBN group and 1424 in the conventional care group. The analyses revealed that patients with AA who experienced EBN were significantly less likely to develop postoperative wound infections (odds ratio [OR] = 0.23, 95% confidence intervals [CIs]: 0.14-0.38, p < 0.001) and postoperative complications (OR = 0.20, 95% CI: 0.15-0.26, p < 0.001) as opposed to conventional care. Available evidence suggests that EBN can effectively reduce the risk of wound infection and postoperative complications in patients undergoing appendectomy for AA, thereby improving patient prognosis. This finding is worth promoting in the clinical practice.

Abstract
BACKGROUND Appendicitis is a common surgical condition that requires urgent medical attention. Recent advancements in artificial intelligence and large language processing, such as ChatGPT, have demonstrated potential in supporting healthcare management and scientific research. This study aims to evaluate the accuracy and comprehensiveness of ChatGPT's knowledge on appendicitis management. METHODS Six questions related to appendicitis management were created by experienced RACS qualified general surgeons to assess ChatGPT's ability to provide accurate information. The criteria of ChatGPT answers' accuracy were compared with current healthcare guidelines for appendicitis and subjective evaluation by two RACS qualified General Surgeons. Additionally, ChatGPT was then asked to provide five high level evidence references to support its responses. RESULTS ChatGPT provided clinically relevant information on appendicitis management, however, was inconsistent in doing so and often provided superficial information. Further to this, ChatGPT encountered difficulties in generating relevant references, with some being either non-existent or incorrect. CONCLUSION ChatGPT has the potential to provide timely and comprehensible medical information on appendicitis management to laypersons. However, its issue of inaccuracy in information and production of non-existent or erroneous references presents a challenge for researchers and clinicians who may inadvertently employ such information in their research or healthcare. Therefore, clinicians should exercise caution when using ChatGPT for these purposes.

Outcome of Laparoscopic Versus Open Appendectomy for Acute Appendicitis-Results of a Propensity Score Matching Analysis of 542 Patients and Consequences for the Military Surgeon. Mil Med 2024; 189:e632-e637.

Abstract
INTRODUCTION Appendectomy is the treatment of choice for acute appendicitis. The procedure can be performed open or laparoscopically. However, laparoscopy is not available on military missions abroad. It is unclear whether treatment outcomes differ between the two surgical approaches. MATERIALS AND METHODS Treatment data of all patients undergoing open and laparoscopic appendectomies in the German Armed Forces Hospital of Ulm from 2013 to 2017 were collected retrospectively. A propensity score matching analysis was performed to minimize the influence of potential confounders and to assess the influence of surgical approach on outcome (reoperations, superficial and deep surgical infections, length of postoperative ileus, need for intravenous analgesics, and operative time). RESULTS A total of 542 patients with complete datasets were included in the propensity score matching analysis, among these 64 with open and 478 laparoscopic procedures. There were no statistically significant differences between open and laparoscopic surgeries with respect to all outcome variables, with the exception of a 25-minute prolonged operative time for the open approach. CONCLUSIONS Open appendectomy can be considered equivalent in outcome to the laparoscopic procedure and thus can be performed on military missions abroad without compromising outcome. Military surgeons must continue to be trained and confident in open appendectomy.

Abstract
BACKGROUND Several factors are associated with increased postoperative complications after appendectomies. However, few studies combined these potential factors for comprehensive prediction of surgical outcomes. Whether high-risk patients benefit from a shorter waiting time for surgery remains unclear. This study aimed to explore the impact of surgical waiting time and potential risk factors on postoperative complications. METHODS A total of 1343 patients diagnosed with acute appendicitis requiring an emergent appendectomy were included from 2013 to 2018. The preoperative risk factors associated with postoperative complications were selected and the probability of postoperative complications was calculated by multivariate logistic regression model. Patients were divided into four groups based on the risk (high & low) and time to surgery (> 12 & ≤12 hours). The odds ratios for complications were evaluated between groups. RESULTS The selected risk factors included age, neutrophil-lymphocyte ratio, systemic inflammatory response syndrome and abdominal pain duration. Compared with low-risk patients with time to surgery ≤12 hours, high-risk patients with time to surgery > 12 hours had significant increased overall postoperative complication rate (16.85% vs. 8.16%, p = 0.002) and a trend toward increased surgical site infection rate (10.99% vs. 6.46%, p = 0.058). When operated within 12 hours, there was no difference in outcomes between high- and low-risk patients. On the other hand, time to surgery > 12 hours did not increase complication rate in low-risk patients. CONCLUSIONS The surgical outcome may be affected by preoperative factors and time to surgery. It is suggested that high-risk patients receive appendectomy within 12 hours to avoid increased postoperative complications.

Abstract
This case report explores the feasibility and efficacy of endoscopic retrograde appendicitis therapy (ERAT) in treating a 42-year-old female with subacute appendicitis complicated by an abscess. The patient, initially presenting with abdominal pain, underwent an endoscopic intervention involving drainage, irrigation, and stent placement in the appendix. The study discusses the patient's successful outcome, emphasizing the role of ERAT in managing complicated appendicitis with abscesses. The report outlines the case presentation with the initial misdiagnosis of cecal intussusception. The endoscopic procedure involved identifying a partially prolapsed appendix, spontaneous drainage of purulent discharge, and subsequent stent placement to facilitate drainage while awaiting definitive surgery. The patient's positive response to ERAT was marked by pain reduction and a follow-up CT scan confirming the absence of an abscess and a normal appendix. The case report asserts that ERAT emerges as a promising alternative to immediate appendectomy for patients with subacute appendicitis complicated by abscesses, enhancing symptom relief and reducing major adverse events.

Abstract
Recent studies have discussed the role of antibiotic treatment in the conservative management of acute appendicitis and whether antibiotics are a safe option to replace appendicectomy, which has been the gold standard treatment of acute appendicitis for many years. The bibliographic databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane, Embase, Medline, and PubMed comparing conservative versus surgical treatment of acute appendicitis were systematically searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Twenty-one studies consisting of systematic reviews and meta-analyses involving 44,699 participants were identified. At least 17,865 participants were treated with antibiotics. Our studies compare antibiotic versus appendicectomy among acute appendicitis patients ranging from 7 to 94 years of age. In most studies, patients received parenteral antibiotics for a total of one to three days, and oral antibiotics such as oral cephalosporin plus metronidazole, oral amoxicillin/clavulanate, oral fluoroquinolones plus Tinidazole upon hospital discharge for a total of 7 to 10 days. The total course of antibiotics for both parenteral and oral regimes ranged from 2 to 16 days, with 10 days being the commonest duration. The recurrence rate following initial antibiotic treatment at one-year follow-up ranged from 13% to 38%, while the mean duration of recurrence ranged from three to eight months. The majority of the patients with recurrence underwent appendicectomy, while some patients were either given a repeat or different course of antibiotics due to the possible presence of antibiotic resistance; however, only 2.4% of the patients were successfully treated upon completion of the second course of antibiotics. Most of the studies concluded that appendicectomy remains the gold standard treatment for uncomplicated acute appendicitis, given its higher efficacy and lower complication rates. Although antibiotic treatment cannot be routinely recommended, it can be considered an appropriate alternative in selected patients with uncomplicated appendicitis who wish to avoid surgery and also acknowledge the risk of recurrence and the potential need for subsequent surgery at the same time.

Abstract
Background Previous research has posited a potential correlation between the gut microbiota and the onset of appendicitis; however, the precise causal connection between appendicitis and the gut microbiota remains an unresolved and contentious issue. Methods In this investigation, we performed a Mendelian randomization (MR) analysis employing publicly accessible summary data extracted from genome-wide association studies (GWAS) to elucidate the potential causal nexus between the gut microbiota and the development of appendicitis. We initially identified instrumental variables (IVs) through a comprehensive array of screening methodologies, subsequently executing MR analyses using the Inverse Variance Weighted (IVW) technique as our primary approach, supplemented by several alternative methods such as MR Egger, weighted median, simple mode, and weighted mode. Additionally, we implemented a series of sensitivity analysis procedures, encompassing Cochran's Q test, MR-Egger intercept test, Mendelian Randomized Polymorphism Residual and Outlier (MR-PRESSO) test, and a leave-one-out test, to affirm the robustness and validity of our findings. Results Our investigation indicates that an elevated prevalence of Deltaproteobacteria, Christensenellaceae, Desulfovibrionaceae, Eubacterium ruminantium group, Lachnospiraceae NK4A136 group, Methanobrevibacter, Desulfovibrionales, and Euryarchaeota is inversely associated with the risk of appendicitis. Conversely, we observed a positive correlation between an increased abundance of Family XIII, Howardella, and Veillonella and the susceptibility to appendicitis. Sensitivity analyses have corroborated the robustness of these findings, and Mendelian randomization analyses provided no indications of reverse causality. Conclusion Our Mendelian randomization (MR) analysis has unveiled potential advantageous or detrimental causal associations between the gut microbiota and the occurrence of appendicitis. This study offers novel theoretical and empirical insights into the understanding of appendicitis pathogenesis, along with its implications for preventive and therapeutic strategies.

Abstract
OBJECTIVE To investigate the incidence of occult appendiceal neoplasm in patients aged 40 years and over who underwent appendicectomy for appendicitis. METHODS The clinical coding electronic database was used to identify patients aged 40 years and over who were diagnosed with appendicitis from September 2010 to September 2022. Patients were included if they were managed operatively. DESIGN Retrospective cohort study. SETTING Modified Monash category 3 (large rural town). PARTICIPANTS Patients aged 40 years and over undergoing appendicectomy for appendicitis. MAIN OUTCOME MEASURES Incidence of appendiceal neoplasm within appendicectomy specimen. RESULTS A total of 279 patients aged 40 years and over underwent appendicectomy, with a median age of 53 years (range 40-95). Nineteen patients (7%) were found to have a primary neoplastic lesion within the appendix: seven neuroendocrine neoplasms (37%), six sessile serrated lesions (32%), two colonic-type adenocarcinoma (11%), two goblet cell adenocarcinoma (11%) and two appendiceal mucinous neoplasms (11%). Additionally, one patient had a metastatic adenocarcinoma of pancreaticobiliary aetiology. CONCLUSIONS Occult appendiceal neoplasm was higher than reported in the literature in our cohort. This would support appendicectomy as the treatment of choice for patients aged 40 years and over with acute appendicitis and caution against nonoperative management in this demographic.

Abstract
Appendicitis is a prevalent surgical emergency. Although appendectomy has traditionally been the go-to treatment, recent studies suggest antibiotics can be equally effective for uncomplicated cases. However, evidence is scant regarding patients with hematologic disorders. This study delves into the surgical risks tied to appendicitis in patients with underlying hematologic conditions. A retrospective analysis was carried out on patients diagnosed with appendicitis and hematologic disorders from January 2000 to June 2021. Patients were pinpointed using ICD-10 diagnostic codes, and surgical procedures were identified based on the hospital's surgical fee codes. Hematologic conditions were sorted into risk levels, and patient treatments were scrutinized. Among the 131 initially identified patients, 89 were included in the study. Out of these, 75 underwent surgical procedures, while 14 received non-surgical treatments. The surgical group displayed better preoperative laboratory outcomes. Clinical characteristics, hematologic disease risk, and severity of appendicitis appeared not to be related to surgical complications. Patients without surgical complications showed improvement in preoperative absolute neutrophil count (ANC) and platelet counts. Lower preoperative ANCs and platelet counts were associated with extended hospital stays. For patients with hematologic disorders diagnosed with appendicitis, thorough preoperative laboratory evaluations followed by minimally invasive appendectomy appear to be a safe route without heightening the risk of severe complications compared to non-surgical management.

Abstract
BACKGROUND Low-impact laparoscopy (LIL), combining low-pressure insufflation and microlaparoscopy, is a surgical technique that is still not widely used and that has never been evaluated for the management of acute appendicitis. The aim of this study is to assess the feasibility of an LIL protocol, to compare postoperative pain, average length of stay, and in-hospital use of analgesics by patients who underwent appendectomy according to a conventional laparoscopy or an LIL protocol. STUDY DESIGN Patients presenting with acute uncomplicated appendicitis who were operated on between January 1, 2021, and July 10, 2022, were included in this double-blind, single-center, prospective study. They were preoperatively randomly assigned to a group undergoing conventional laparoscopy, ie with an insufflation pressure of 12 mmHg and conventional instrumentation, and an LIL group, with an insufflation pressure of 7 mmHg and microlaparoscopic instrumentation. RESULTS Fifty patients were included in this study, 24 in the LIL group and 26 in the conventional group. There were no statistically significant differences between the 2 patient groups, including weight and surgical history. The postoperative complication rate was comparable between the 2 groups (p = 0.81). Pain was reported as significantly lower according to the visual analog scale 2 hours after surgery among the LIL group (p = 0.019). For patients who underwent surgery according to the LIL protocol, the study confirms a statistically significant difference for theoretical and actual length of stay, ie -0.77 days and -0.59 days, respectively (p < 0.001 and p = 0.03). In-hospital use of analgesics was comparable between both groups. CONCLUSIONS In uncomplicated acute appendicitis, the LIL protocol could reduce postoperative pain and average length of stay compared to conventional laparoscopic appendectomy.

Abstract
Introduction: Acute appendicitis is the most common surgical emergency in pregnant women. There has been a wide variance in clinical practice worldwide, with some favoring an antibiotic-only approach while others prefer surgery as the first-line management. Therefore, we designed the current analysis to synthesize the available evidence on the efficacy and safety of antibiotics versus surgery management. Methods: We searched PubMed, Scopus, EuropePMC, and Cochrane Central from March 4, 1904 until November 25, 2022, to look for studies comparing antibiotics and surgery in pregnant patients with acute appendicitis. We only included studies that provided a comparison between the two treatments. We included preterm delivery, fetal loss, maternal death, and complications as outcomes. The results were compared using an odds ratio and 95% confidence interval. We also performed a sensitivity analysis by excluding studies with a serious risk of bias. Results: We included five non-randomized studies for the analysis. We found that patients in the antibiotic group had a lower risk of preterm labor (OR 0.63 [95% CI 0.43-0.92]; p 0.02) but a higher risk of complications (OR 1.79 [95% CI 1.19-2.69]; p 0.005). We did not find any difference in the other outcomes. Conclusion: The increased risk of complications should caution clinicians about using antibiotics as the first-line management. More studies are required to identify patients who would benefit the most before antibiotics could be adopted as a treatment for acute appendicitis in pregnant patients.

Abstract
Background Acute appendicitis is the most common digestive disease requiring emergency surgery. Colorectal cancer is the third most common cancer in France. An increased risk of colorectal cancer after acute appendicitis has been suggested. We aimed to assess the frequency of hospitalization for colon cancer after appendicitis in a nationwide analysis. Methods Using the French Hospital Discharge Database (PMSI), we included all patients aged 18-59 years presenting with acute appendicitis between 2010 and 2015. Univariate and multivariate analyses were performed to compare colon cancer occurrence in these patients vs a control-matched population with a hospital stay for trauma in the same period. Patients presenting strong risk factors for colorectal cancer were excluded. Findings A total of 230,349 patients with acute appendicitis (exposed group) were included. We used a propensity score to match each exposed patient with two unexposed patients (controls) to ensure the comparability of the groups, resulting in a control group of 460,698 patients. Univariate analysis found significantly more colon cancer in the appendicitis group, especially during the first year after appendicitis (5 per 10,000 vs 1 per 10,000, p < 0.000, this corresponds to 111 patients in the appendicitis group), namely within the first 6 months. Survival analysis confirmed patients treated for appendicitis present a 4 times higher risk of being diagnosed with colon cancer than control patients during the first year of follow-up (sHR = 4.67 (95% CI: 3.51-6.21), and 8 times higher during the first 6 months (sHR = 8.39; 95% CI: 5.41-12.99). The association was even more marked for right-sided colon cancer (sHR = 8.25; 95% CI: 5.03-13.54 during the 1st year). While the risk of diagnosis of colon cancer was also significant for patients over 40 years, it was even greater in patients under 40 years, who had between a 6-fold and 12-fold increase in risk. Interpretation In this population-based study, we found that acute appendicitis seems to be a warning sign for colon cancer (reverse causality) in both middle-aged and younger adults. The risk of presenting with cancer colon was higher during the first six months after acute appendicitis. This raises the issue of routine diagnostic work-up in adults presenting with acute appendicitis. Funding Regional Council of Burgundy.

Abstract
Prior to the development of laparoscopic procedures, open appendectomy was the standard of care for the majority of appendicitis cases. Recently, studies have debated using antibiotics as a first-line treatment in uncomplicated appendicitis cases. The definition of uncomplicated appendicitis is not always clear-cut; however, with the large-scale accessibility of radiologic techniques, it is becoming increasingly easier to classify patient groups. As suggested by clinical and radiological patient data, this has raised the speculation of considering antibiotic therapy as the sole treatment modality in uncomplicated appendicitis cases. We aim to compare the options of surgery and antibiotics only in terms of efficacy, complications, and financial cost. A range of databases and search strategies were adopted, and various databases were used, including PubMed, ScienceDirect, Google Scholar, and JAMA. Collectively, 30 studies were reviewed, but only 18 were included. Efficacy rates were higher in the appendectomy group. Nevertheless, the antibiotics-only group maintained an efficacy rate greater than 70% at one-year follow-up. Risk factors that decreased the efficacy in medical management included the presence of appendicolith, neoplasm, appendiceal dilatation, peri-appendiceal fluid collection, higher mean temperature, CRP, and bilirubin. Complications were more frequent and significant in the surgery group. These included complications related to anaesthesia, surgical site infections, damage to nearby structures, and pulmonary embolism. Despite several years of follow-up and disease recurrences, higher financial costs were observed in surgically treated patients compared to the antibiotics-only group. Given the high success rates post-appendectomy for acute appendicitis over the decades, the efficacy of conservatively treated acute appendicitis raises a strong argument when choosing one of the two options. The efficacy remained consistently higher across the literature in the surgery group than in the antibiotics-only group. However, it is still arguable that antibiotics may be a preferable option given an efficacy rate of more than 70% at one year and overall higher complications associated with surgery. The argument of missing a neoplasm by avoiding surgery is valid. However, most are carcinoid neuroendocrine neoplasms with a low probability of metastasis (<5%) and are usually considered benign. Given the current practice focused on conservative and minimally invasive treatments and recently the COVID-19 pandemic, with its restrictions and lessons learnt, antibiotics may be the future standard for treating uncomplicated acute appendicitis. Lastly, we noticed higher efficacy rates in articles published recently than those published at least five to ten years earlier. Antibiotics-only therapy for uncomplicated appendicitis is cost-effective with fewer complications than surgery. However, appendectomies have higher efficacy. Thus, surgical treatment prevails as the standard of care. Future literature should yield larger sample sizes and explore the numbers of emergency appendectomies mandated following antibiotics-only therapy.

Abstract
INTRODUCTION Conservative management with antibiotics was recommended by the UK Surgical Royal Colleges early in the COVID-19 pandemic as the first-line treatment for acute uncomplicated appendicitis. METHODS This is a prospective single-centre cohort study of patients aged 16 years or over, diagnosed clinically and confirmed radiologically with acute appendicitis in a secondary care setting who were initially treated conservatively with antibiotics. The primary outcome was the response to conservative management with antibiotics. Secondary outcomes were: antibiotic duration; operative rates; surgical approach (open, laparoscopic or conversion to open); complication rates; COVID-19 positive rate; rates of readmission within 12 months; and length of hospital stay. RESULTS A total of 109 patients were included in the study, 67 of whom were male. Median age was 37 (range 17-93) years. A further 28 patients were excluded because of a decision to manage operatively on the index admission or because of other diagnoses. Thirty-three patients (30.3%) had surgery on the index admission after failed conservative management and 15 (13.8%) had surgery on readmission. On histology, 32/48 patients (66.7%) had a diagnosis of complicated appendicitis and 18/48 (37.5%) had a confirmed appendicolith. CONCLUSIONS There was a high readmission rate (47/109; 43.1%) for surgery, a radiological drain or conservative management within the first year following initial conservative management. There is a significant risk of recurrence of symptoms, particularly in the presence of an appendicolith. Laparoscopic appendicectomy should be the first-line treatment, with conservative management reserved for patients with acute uncomplicated appendicitis who are COVID-19 positive or have comorbidities.

Abstract
Appendiceal cancers (AC) are a rare and heterogeneous group of malignancies. Historically, appendiceal neoplasms have been grouped with colorectal cancers (CRC), and treatment strategies have been modeled after CRC management guidelines due to their structural similarities and anatomical proximity. However, the two have marked differences in biological behavior and treatment response, and evidence suggests significant discrepancies in their respective genetic profiles. In addition, while the WHO classification for appendiceal cancers is currently based on traditional histopathological criteria, studies have demonstrated that histomorphology does not correlate with survival or treatment response in AC. Due to their rarity, appendiceal cancers have not been studied as extensively as other gastrointestinal cancers. However, their incidence has been increasing steadily over the past decade, making it crucial to identify new and more effective strategies for detection and treatment. Recent efforts to map and understand the molecular landscape of appendiceal cancers have unearthed a wealth of information that has made it evident that appendiceal cancers possess a unique molecular profile, distinct from other gastrointestinal cancers. This review focuses on the epigenetic landscape of epithelial appendiceal cancers and aims to provide a comprehensive overview of the current state of knowledge of epigenetic changes across different appendiceal cancer subtypes, highlighting the challenges as well as the promise of employing epigenetics in the quest for the detection of biomarkers, therapeutic targets, surveillance markers, and predictors of treatment response and survival in epithelial appendiceal neoplasms.

Comparison of the efficacy and safety of antibiotic treatment and appendectomy for acute uncomplicated appendicitis: a systematic review and meta-analysis. BMC Surg 2023; 23:208. [PMID: 37488583 PMCID: PMC10367319 DOI: 10.1186/s12893-023-02108-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 07/14/2023] [Indexed: 07/26/2023] Open
Abstract
OBJECTIVE This meta-analysis aimed to compare the efficacy and safety of antibiotic treatment and appendectomy for acute uncomplicated appendicitis. METHODS We searched the randomized controlled studies (RCTs) comparing appendectomy with antibiotic treatment for uncomplicated acute appendicitis in the electronic database including Pubmed, Embase, Cochrane, Web of Science, CNKI, VIP, and WanFang. The primary outcomes included complication-free treatment success at 1 year, complications, surgical complications, and the complicated appendicitis rates. Secondary outcomes included negative appendicitis, length of hospital stay, the quality of life at 1 month, and the impact of an appendicolith on antibiotic therapy. RESULTS Twelve randomized controlled studies were included. Compared with surgery group, the antibiotic group decreased the complication-free treatment success at 1 year (RR 0.81; 95% CI 0.73-0.91; z = 3.65; p = 0.000). Statistically significance was existed between antibiotic group and surgical group with both surgical types(open and laparoscopic) (RR 0.43; 95% CI 0.31-0.58; z = 5.36; p = 0.000), while no between the antibiotic treatment and laparoscopic surgery (RR 0.72; 95% CI 0.41-1.24; z = 1.19; p = 0.236). There was no statistically significant differences between two groups of surgical complications (RR 1.38; 95% CI 0.70-2.73; z = 0.93; p = 0.353), the complicated appendicitis rate (RR 0.71; 95% CI 0.36-1.42; z = 0.96; p = 0.338), negative appendectomy rate (RR 1.11; 95% CI 0.69-1.79; z = 0.43; p = 0.670), duration of hospital stay (SMD 0.08; 95%CI -0.11-0.27; z = 0.80; p = 0.422), and quality of life at 1 month (SMD 0.09; 95%CI -0.03-0.20; z = 1.53; p = 0.127). However, in the antibiotic treatment group, appendicolith rates were statistically higher in those whose symptoms did not improve (RR 2.94; 95% CI 1.28-6.74; z = 2.55; p = 0.011). CONCLUSIONS Although the cure rate of antibiotics is lower than surgery, antibiotic treatment is still a reasonable option for patients with uncomplicated acute appendicitis who do not want surgery without having to worry about complications or complicating the original illness.

Abstract
Intra-abdominal infections (IAI) are among the most common global healthcare challenges and they are usually precipitated by disruption to the gastrointestinal (GI) tract. Their successful management typically requires intensive resource utilization, and despite the best therapies, morbidity and mortality remain high. One of the main issues required to appropriately treat IAI that differs from the other etiologies of sepsis is the frequent requirement to provide physical source control. Fortunately, dramatic advances have been made in this aspect of treatment. Historically, source control was left to surgeons only. With new technologies non-surgical less invasive interventional procedures have been introduced. Alternatively, in addition to formal surgery open abdomen techniques have long been proposed as aiding source control in severe intra-abdominal sepsis. It is ironic that while a lack or even delay regarding source control clearly associates with death, it is a concept that remains poorly described. For example, no conclusive definition of source control technique or even adequacy has been universally accepted. Practically, source control involves a complex definition encompassing several factors including the causative event, source of infection bacteria, local bacterial flora, patient condition, and his/her eventual comorbidities. With greater understanding of the systemic pathobiology of sepsis and the profound implications of the human microbiome, adequate source control is no longer only a surgical issue but one that requires a multidisciplinary, multimodality approach. Thus, while any breach in the GI tract must be controlled, source control should also attempt to control the generation and propagation of the systemic biomediators and dysbiotic influences on the microbiome that perpetuate multi-system organ failure and death. Given these increased complexities, the present paper represents the current opinions and recommendations for future research of the World Society of Emergency Surgery, of the Global Alliance for Infections in Surgery of Surgical Infection Society Europe and Surgical Infection Society America regarding the concepts and operational adequacy of source control in intra-abdominal infections.

ULTRASOUND IN MEDICINE & BIOLOGY 2023; 49:1611-1615. [PMID: 37032239 DOI: 10.1016/j.ultrasmedbio.2023.03.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 02/24/2023] [Accepted: 03/12/2023] [Indexed: 05/17/2023]
Abstract
OBJECTIVE Point-of-care ultrasound (PoCUS) has high sensitivity and specificity in diagnosing uncomplicated colonic diverticulitis in Western patients. Evidence regarding the accuracy of PoCUS in Asian patients in which diverticulitis frequently occurs in the right-side colon is lacking. This multicenter, 10-y study was aimed at evaluating the diagnostic accuracy of PoCUS in various locations of uncomplicated diverticulitis among Asians. METHODS A convenience sample of patients with suspected colonic diverticulitis who had undergone computed tomography (CT) were eligible. Patients undergoing PoCUS before CT were included. The primary outcome was the diagnostic accuracy of PoCUS in the various locations, compared with the final diagnosis made by the expert physicians. The sensitivity, specificity, positive predictive value and negative predictive value were computed. The logistic regression model was used to investigate the possible factors related to the accuracy of PoCUS. RESULTS A total of 326 patients were included. The overall accuracy of PoCUS was 92% (95% confidence interval [CI]: 89.1%-95.0%) and was lower in the cecum (84.3%, 95% CI: 77.8%-90.8%), compared with other locations (p < 0.0001). Nine of 10 false positives had the final diagnosis of appendicitis: 5 had an outpouching structure whose origin in the cecum could not be traced and 4 had elongated "diverticula." Moreover, body mass index was negatively associated with the accuracy of PoCUS in cecal diverticulitis (odds ratio: 0.79, 95% CI: 0.64-0.97) after adjusting for other covariates. CONCLUSION Point-of-care ultrasound exhibits high diagnostic accuracy in diagnosing uncomplicated diverticulitis in the Asian population. However, the accuracy varies according to location, and was relatively low in the cecum.

Abstract
OBJECTIVES To perform a systematic review on the use of magnetic resonance imaging (MRI) of the abdomen to evaluate clinically suspected appendicitis in the general adult population. We examined the diagnostic accuracy, the reported trends of MRI use, and the factors that affect the utility of MRI abdomen, including study duration and cost-benefits. METHODS We conducted a systematic literature search on PubMed, MEDLINE, Embase, Web of Science, and Cochrane Library databases. We enrolled primary studies investigating the use of MRI in diagnosing appendicitis in the general adult population, excluding studies that predominantly reported on populations not representative of typical adult appendicitis presentations, such as those focusing on paediatric or pregnant populations. RESULTS Twenty-seven eligible primary studies and 6 secondary studies were included, totaling 2,044 patients from eight countries. The sensitivity and specificity of MRI for diagnosing appendicitis were 96% (95% CI: 93-97%) and 93% (95% CI: 80-98%), respectively. MRI can identify complicated appendicitis and accurately propose alternative diagnoses. The duration of MRI protocols in each primary study ranged between 2.26 and 30 minutes, and only one study used intravenous contrast agents in addition to the non-contrast sequences. Decision analysis suggests significant benefits for replacing computed tomography (CT) with MRI and a potential for cost reduction. Reported trends in MRI usage showed minimal utilisation in diagnostic settings even when MRI was available. CONCLUSIONS MRI accurately diagnoses appendicitis in the general adult population and improves the identification of complicated appendicitis or alternative diagnoses compared to other modalities using a single, rapid investigation.

Abstract
Background The coexistence of Crohn's disease (CD) and acute appendicitis (AA) is rare. In this situation, therapeutic experience is lacking and the strategy is paradoxical and intractable. Appendectomy is the gold standard for the treatment of AA whereas a nonsurgical approach is recommended for CD. Case summary A 17-year-old boy was hospitalized for right lower abdominal pain with fever of 3 days. He had the CD for 8 years. Two years ago, he underwent surgery for anal fistula with the complication of CD. His temperature was elevated at 38.3°C at admission. On physical examination, there was McBurney tenderness with mild rebound tenderness. Abdominal ultrasonography showed that the appendix was notably enlarged and dilated at 6.34 cm long and 2.76 cm wide. These findings were suggestive of uncomplicated AA in this patient with active CD. Endoscopic retrograde appendicitis therapy (ERAT) was performed. The patient had complete pain relief immediately after the procedure without tenderness in the right lower abdomen. During 18 mo follow-up, he had no more attacks in his right lower abdomen. Conclusion ERAT was effective and safe in a CD patient with coexisting AA. Such cases can avoid surgery and its-related complications.

[PMID: 37274135 PMCID: PMC10238878 DOI: 10.1016/j.sopen.2023.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 05/10/2023] [Indexed: 06/06/2023] Open
Abstract
Background Acute appendicitis is one of the most common surgical emergencies worldwide. Preoperative assessment of the risk of complicated appendicitis may aid in treatment planning. We sought to investigate the association between pre-appendectomy hyponatremia and diagnosis of complicated appendicitis. Methods The TriNetX platform, a federated health research network that aggregates de-identified electronic health record data of over 90 million patients across the United States, was queried for patients who underwent appendectomy starting January 2019 and who had at least one sodium value from the preoperative period. The study population was stratified into three age groups: pediatric (age < 18), adult (age 18-64), and older adult (age ≥ 65). These groups were subdivided into patients with preoperative hyponatremia (<135 mmol/L) and normonatremia (135-145 mmol/L). Results Among the 61,245 patients who met inclusion criteria, 17,546 were included for analysis following propensity score matching. The odds of complicated appendicitis were highest in pediatric patients (age < 18) with pre-appendectomy hyponatremia (odds ratio [OR] = 2.91, 95 % CI [2.53, 3.35]). Patients age 18-64 and aged ≥ 65 with preoperative hyponatremia also demonstrated increased odds of a complicated appendicitis diagnosis, but to a lesser extent (OR = 2.11, 95 % CI [1.92, 2.32] (OR = 1.49, 95 % CI [1.25, 1.77], respectively). Conclusions In a large analysis of matched patients with acute appendicitis, we found an association between immediate preoperative hyponatremia and complicated appendicitis. Future studies are indicated to further evaluate the role of hyponatremia as a potential diagnostic marker for complicated appendicitis in all age groups. Key message This study suggests a role of hyponatremia as one of multiple variables to incorporate into future clinical decision tools for complicated acute appendicitis.

Single center data from a tertiary care hospital in Germany. Innov Surg Sci 2023; 8:39-48. [PMID: 38058775 PMCID: PMC10696938 DOI: 10.1515/iss-2022-0021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 04/03/2023] [Indexed: 12/08/2023] Open
Abstract
Objectives The unexpected global overload of the health system during COVID-19 pandemic has caused changes in management of acute appendicitis worldwide. Whereas conservative treatment was widely recommended, the appendicectomy remained standard therapy in Germany. We aimed to investigate the impact of COVID-19 pandemic on treatment routine for acute appendicitis at University Hospital of Magdeburg. Methods Adult patients with clinical and/or radiological diagnosis of acute appendicitis were included in the single center retrospective study. Data was collected to patient demographics, treatment modality and outcomes including morbidity and length of stay. The patient data related to COVID-19 period from March 22, 2020 to December 31, 2021 (649 days) were compared to the Non-COVID-19 period from June 12, 2018 to March 21, 2020 (649 days). Subgroup analysis related to conservative or surgical treatment has been performed. Results A total of 385 patients was included in the study, 203 (52.73 %) during Non-COVID-19 period and 182 (47.27 %) during COVID-19 period. Mean age of entire collective was 43.28 years, containing 43.9 % female patients (p=0.095). Conservative treatment was accomplished in 49 patients (12.7 % of entire collective), increasing from 9.9 % to 15.9 % during COVID-19 period (p=0.074). Laparoscopic appendicectomy was performed in 99.3 % (n=152) of operated patients during COVID-19 period (p=0.013), followed by less postoperative complications compared to reference period (23.5 % vs. 13.1 %, p=0.015). The initiation of antibiotic therapy after the diagnosis increased from 37.9 % to 53.3 % (p=0.002) during COVID-19 period regardless the following treatment modality. Antibiotic treatment showed shorter duration during pandemic period (5.57 days vs. 3.16 days, p<0.001) and it was given longer in the conservative treatment group (5.63 days vs. 4.26 days, p=0.02). The overall length of stay was shorter during COVID-19 period (4.67 days vs. 4.12 days, p=0.052) and in the conservative treatment group (3.08 days vs. 4.47 days, p<0.001). However, the overall morbidity was lower during the COVID-19 period than before (17.2 % vs. 7.7 %, p=0.005) and for conservative therapy compared to appendicectomy (2 % vs. 14.3 %, p=0.016). There was no mortality documented. Conclusions According to our findings the COVID-19 pandemic had a relevant impact on treatment of acute appendicitis, but it was possible to maintain the traditional diagnostic and treatment pathway. Although laparoscopic appendicectomy remains a recommended procedure, the conservative treatment of uncomplicated appendicitis with excellent short-term outcome can be a safe alternative to surgery during potential new wave of COVID-19 pandemic and in the daily routine.

Abstract
PURPOSE Appendicitis is a common cause of acute abdominal pain, and treatment with laparoscopy has become increasingly common during the past two decades. Guidelines recommend that normal appendices are removed if operated for suspected acute appendicitis. It is unclear how many patients are affected by this recommendation. The aim of this study was to estimate the rate of negative appendectomies in patients undergoing laparoscopic surgery for suspected acute appendicitis. METHODS This study was reported following the PRISMA 2020 statement. A systematic search was conducted in PubMed and Embase for retrospective or prospective cohort studies (with n ≥ 100) including patients with suspected acute appendicitis. The primary outcome was the histopathologically confirmed negative appendectomy rate after a laparoscopic approach with a 95% confidence interval (CI). We performed subgroup analyses on geographical region, age, sex, and use of preoperative imaging or scoring systems. The risk of bias was assessed using the Newcastle-Ottawa Scale. Certainty of the evidence was assessed using GRADE. RESULTS In total, 74 studies were identified, summing up to 76,688 patients. The negative appendectomy rate varied from 0% to 46% in the included studies (interquartile range 4-20%). The meta-analysis estimated the negative appendectomy rate to be 13% (95% CI 12-14%) with large variations between the individual studies. Sensitivity analyses did not change the estimate. The certainty of evidence by GRADE was moderate due to inconsistency in point estimates. CONCLUSION The overall estimated negative appendectomy rate after laparoscopic surgery was 13% with moderate certainty of evidence. The negative appendectomy rate varied greatly between studies.

Updates Surg 2023:10.1007/s13304-023-01513-8. [PMID: 37119455 DOI: 10.1007/s13304-023-01513-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 04/17/2023] [Indexed: 05/01/2023]
Abstract
The HALP score, which is a combined index composed of hemoglobin, albumin, lymphocyte, and platelet, is a new indicator showing both inflammation and nutritional status. This study aims to evaluate the relationship of this combined index consisting of simple laboratory values with the degree of appendicitis complication and postoperative results in patients operated on for acute appendicitis. The data of 684 patients operated for acute appendicitis between January 2017 and December 2022 and inclusion criteria were analyzed with a single-center retrospective cross-sectional study design. Using routine laboratory data, patients' HALP scores were divided into two groups as low and high. The cut-off value of the HALP score according to the presence of postoperative complications was determined as < 31.2 by ROC analysis and the ROC curve. Patients were grouped as HALP score cut-off value below (group 1) and above (group 2). Complicated appendicitis and postoperative outcomes were compared to the HALP score groups. According to the cut-off value of the HALP score, 113 (16.5%) of the patients were in Group 1, and 571 (83.5%) were in Group 2. Complications developed in 15 (26%) patients (p < 0.001). Low HALP scores were a significant risk factor for peri-appendicular abscess (OR 29.12 95% CI 12.39-68.43), appendicitis perforation (OR = 20.82 95% 12.67-34.19), gangrenous appendicitis (OR = 35, 54, 95% 13.33-94.77), and postoperative complications (OR = 15.29 95% 7.95-29.41) (p < 0.001). Besides clinical and radiological findings, the HALP score shows the degree of acute appendicitis complication. It can be used as a simple, inexpensive, and easily applicable diagnostic tool.

Age-related disparities and trends in national healthcare spending for management of appendicitis in the United States: A retrospective cost-analysis. Surgery 2023; 173:896-903. [PMID: 36642654 DOI: 10.1016/j.surg.2022.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 11/29/2022] [Accepted: 12/11/2022] [Indexed: 01/15/2023]
Abstract
BACKGROUND Changes in clinical care for appendicitis have impacted healthcare use associated with treatment. We evaluated national trends and assessed factors associated with healthcare costs for appendicitis in the United States. DESIGN The Disease Expenditure Project, the Global Burden of Disease study, and the National Inpatient Sample were used to estimate total national expenditures, per-capita costs for incident cases, and factors associated with inpatient costs for appendicitis management, respectively. The national estimates of appendicitis costs were obtained from 1996 to 2016. Appendicitis incidence was estimated to calculate per-capita costs. After application of survey weights for the stratified sample design, 191,180 weighted discharges for appendicitis from the 2016 National Inpatient Sample study were evaluated. The Disease Expenditure Project and the Global Burden of Disease study were used to estimate total and per-capita spending. Temporal trends were evaluated using joinpoint regression, expressed as annual percent change. Multivariable linear regression was used to evaluate patient factors associated with total hospital charges. RESULTS In 2016, total spending on appendicitis was $9.3 billion (95% confidence interval: $8.0-$10.8], a 2-fold increase from $4.7 billion ($4.0-$5.3) in 1996. Per-capita spending decreased significantly after 2011 (annual percent change -3.7% [-4.4% to -2.9%]). Patients ≥65 years accounted for 64.1% (61.1%-67.3%) of total spending for appendicitis. The hospital charges for older patients were significantly higher among those undergoing appendectomy. CONCLUSION Overall healthcare spending for appendicitis has doubled from 1996 to 2016, but per capita spending has decreased since 2011, driven by improved efficiency of inpatient care. Nearly two-thirds of spending is on patients ≥65 years, with significantly higher costs associated with surgical management in this population.

Abstract
Appendicitis, an acute inflammation of the appendix, affects all demographic groups and exhibits various incidences and clinical manifestations. While acute appendicitis typically presents with colicky periumbilical abdominal pain that localizes to the right lower quadrant, atypical presentations are more common in children, geriatric, and pregnant patient populations, leading to delays in diagnosis. Clinical evaluation, clinical scoring systems, and inflammatory markers are commonly used, but their limitations have led to the increased use of diagnostic imaging in patients suspected of appendicitis. Acute appendicitis is managed by non-operative and operative management, depending on whether it is uncomplicated or complicated. Developing diagnostic pathways to improve outcomes and reduce complications is crucial. Although medical advancements have been made, diagnosing and managing appendicitis can be challenging, mainly when patients are present atypically. This literature review aims to comprehensively review typical and atypical presentations of appendicitis and their current implications for diagnosis and treatment modalities in pediatric, adult, pregnant, and geriatric patient populations.

Management of Acute Appendicitis During the COVID-19 Pandemic: A Single-Centre Retrospective Cohort Study. Cureus 2023; 15:e37193.

Abstract
BACKGROUND During the coronavirus disease 2019 (COVID-19) pandemic, the management of acute appendicitis shifted towards non-operative management in the United Kingdom (UK). The open approach was recommended over the laparoscopic approach due to the risk of aerosol generation and subsequent contamination. The aim of this study was to compare the overall management and surgical outcomes of the patients treated for acute appendicitis before and during the COVID-19 pandemic. MATERIALS AND METHODS We performed a retrospective cohort study at a single district general hospital in the UK. We compared the management and outcome of the patients diagnosed with acute appendicitis before the pandemic, from March to August 2019, and during the pandemic, from March to August 2020. We looked at the patient demographics, methods of diagnosis, management, and surgical outcomes for these patients. The primary outcome of the study was the 30-day readmission rate. Secondary outcomes included length of stay and post-operative complications. RESULTS Over the period of six months, a total of 179 patients were diagnosed with acute appendicitis in 2019 (Pre-COVID-19 pandemic, from March 1, 2019, to August 31, 2019) versus 152 in 2020 (during the COVID-19 pandemic, from March 1, 2020, to August 31, 2020). For the 2019 cohort, the mean age of the patients was 33 (range 6-86 years), 52% (n=93) were female, and the mean BMI was 26 (range 14-58). For the 2020 cohort, the mean age was 37 (range 4-93 years), 48% (n=73) of the patients were female, and the mean BMI was 27 (range 16-53). At the first presentation, in 2019, 97.2% of the patients (174 out of 179) received surgical treatment compared to 70.4% (107 out of 152) in 2020. Three per cent of the patients (n=5) were managed conservatively in 2019 (two out these failed conservative management) as compared to 29.6% (n=45) in 2020 (21 of these failed conservative management). Pre-pandemic, only 32.4% (n= 57, ultrasound (US) scan: 11, computer tomography (CT) scan): 45, both US and CT: 1) of the patients received imaging to confirm the diagnosis as compared to 53.3% during pandemic (n=81, US scan: 12, CT scan: 63, both US and CT: 6). Overall, the CT to US ratio increased. We found that during 2019, 91.5% (n=161/176) of the patients who received surgical treatment went through laparoscopic surgery as compared to only 74.2% (n=95/128) in 2020 (p<0.0001). Postoperative complications occurred in 5.1% (n=9/176) of the surgical patients in 2019 as compared to 12.5% (n=16/128) in 2020 (p<0.033). The mean length of hospital stay in 2019 was 2.9 days (range 1-11) versus 4.5 days in 2020 (range 1-57) (p<0.0001). The 30-day readmission rate was 4.5% (8/179) versus 19.1% (29/152) (p<0.0001). The 90-day mortality rate was zero for both cohorts. CONCLUSION Our study shows that the management of acute appendicitis changed due to the COVID-19 pandemic. More patients went through imaging, especially CT scans for diagnosis and received non-operative management with antibiotics only. The open surgical approach became more common during the pandemic. This was associated with longer lengths of hospital stay, more readmissions, and an increase in postoperative complications.

Abstract
BACKGROUND The objective of this study is to identify predictors for recurrent appendicitis in patients with appendicitis previously treated nonoperatively. METHODS This is a prospective cohort study of all adult patients with appendicitis treated at a tertiary care hospital. Patient demographics, radiographic information, management, and clinical outcomes were recorded. The primary outcome was recurrent appendicitis within 6 months after discharge from the index admission. Given the competing risk of interval appendectomy, a time-to-event competing-risk analysis was performed. RESULTS Of the 699 patients presenting with appendicitis, 74 were treated nonoperatively (35 [47%] were women; median [IQR] age, 48 [33,64] years), and 21 patients (29%) had recurrent appendicitis. On univariate and multivariate analysis, presence of an appendicolith on imaging was the only factor associated with a higher risk of recurrent appendicitis (p = 0.02). CONCLUSIONS The presence of appendicolith was associated with an increased risk of developing recurrent appendicitis within 6 months.

Abstract
The study aimed to investigate the diagnostic role of multislice spiral CT (MSCT) combined with clinical manifestations and laboratory tests in acute appendicitis subtypes. Patients diagnosed with acute appendicitis were included for retrospective analysis and their clinical manifestations and MSCT signs were analyzed. The clinical manifestations of different subtypes of acute appendicitis, including simple appendicitis, suppurative appendicitis and gangrenous appendicitis, were compared. The clinical manifestations were anorexia in 51.1% of patients, nausea and vomiting in 62.0%, shifting right lower abdominal pain in 51.1%, elevated body temperature in 31.2%, right lower quadrant abdominal tenderness in 91.4%, rebound tenderness in 91.4%, increased white cell count in 89.1%, high neutrophil count in 88.2%, increased appendiceal diameter enlargement in 100%, surrounding exudate in 95.0%, fecal stones in 51.6%, appendiceal wall thickening in 94.6%, lymph node in 82.8% and intestinal stasis in 18.6%. There were statistically significant differences in body temperature and neutrophil percentage among the subtypes of appendicitis and they were lowest in simple appendicitis and highest in gangrenous appendicitis. There were statistically significant differences in appendix diameter and the surrounding exudate among the subtypes of appendicitis and they were lowest in simple appendicitis and highest in gangrenous appendicitis. Clinical manifestations and MSCT signs, especially body temperature, percentage of neutrophils and the surrounding exudate, might have significant diagnostic value in acute appendicitis.

Abstract
To test the effect of a new decision support tool for acute appendicitis and assess its efficacy and acceptability. Background Mounting evidence from randomized controlled trials have shown that antibiotics can be a safe and effective treatment for appendicitis. Patients and surgeons must work together to choose the optimal treatment approach for each patient based on their own preferences and values. We developed a decision support tool to facilitate shared decision-making for appendicitis and its effect on decisional outcomes remains unknown. Methods We conducted an online randomized field test in at-risk individuals comparing the decision support tool to a standard infographic. Individuals were randomized 3:1 to view the decision support tool or infographic. The primary outcome was the total decisional conflict scale (DCS) score measured before and after exposure to the decision support tool. Secondary outcomes included between-group DCS scores, and between-group comparisons of the acceptability. Results One hundred eighty individuals were included in the study. Total DCS scores decreased significantly after viewing the decision support tool (59 [95% confidence interval (CI): 55-63] to 15 [95% CI: 12-17], P < 0.001) representing movement from a state of high to low decisional conflict. Individuals exposed to the decision support tool reported higher acceptability ratings (3.7 [95% CI: 3.6-3.8] vs 3.3 [95% CI: 3.2-3.5] out of 4) and demonstrated increased willingness to consider both treatment options. Conclusions These data support the further use and testing of this novel decision support tool in patients with acute appendicitis.

Abstract
Background Acute appendicitis remains the most common cause of lower abdominal pain leading to emergency visits. Even though the standard treatment of acute appendicitis remains appendectomy, in recent times, multiple randomized control trials and meta-analyses have deduced conservative treatment as a successful alternative treatment. During the coronavirus disease (COVID) pandemic, with a shortage of staff and resources, treatment with conservative management of uncomplicated acute appendicitis became very beneficial under certain circumstances and conditions. This study aimed to assess whether it is effective to manage patients with uncomplicated acute appendicitis with antibiotic therapy. Methodology This was a single hospital based retrospective, cross-sectional study from Jan 2015 to May 2020. Patients with clinical and radiological features of uncomplicated acute appendicitis with Alvarado's score >6 were included in the study. Patients were kept on antibiotics, intravenous fluids, and analgesia as part of a conservative regime. Those who failed to respond to conservative therapy were managed surgically. The follow-up period was six months. Results One hundred eighty-two cases of uncomplicated acute appendicitis were included and managed conservatively, of which 52.2% were males while 47.8% were females. The median age of the patients was 26 years. Conservative treatment was successful in 26.2% of the patients, with a recurrence of 5.5% in the six-month follow-up period. The mean number of days of hospital stay was three days in patients treated with conservative or surgical treatment. Conclusion Conservative management is gaining popularity, and many centers are inclined towards non-operative management; however, appendectomy remains the gold standard treatment for appendicitis.

Abstract
OBJECTIVE To confirm the safety and efficacy of outpatient management of laparoscopic appendectomy, with an enhanced recovery after surgery (ERAS) protocol, in adult patients with uncomplicated acute appendicitis. Outpatient laparoscopic appendectomy is feasible and secure in selected patients in observational studies. The benefits include reduced length of stay (LOS) and postoperative complications. This is the first randomized controlled trial of outpatient management following ERAS protocol. METHODS Patients admitted from the emergency department with acute appendicitis were randomized into one of two groups: standard care within the hospital (HG) or the outpatient group (OG). An ERAS protocol was followed for both groups. Patients in the HG were admitted to the surgical ward. Patients in the OG were referred to the day-surgery unit. The primary endpoint was the length of stay. RESULTS Ninety-seven patients were included: 49 in the OG and 48 in the HG. LOS was significantly shorter in the OG (mean 8.82 h) than in the HG (mean 43.53 h), p < 0.001. There was no difference in readmission rates (p = 0.320); we observed only one readmission in the OG. No further emergency consultations or complications were observed. The cost saving was $516.52/patient as a result of the intervention. CONCLUSION Outpatient management of appendectomy is safe and feasible procedure in selected patients. This approach could become the standard of care for patients with uncomplicated appendicitis, showing fewer complications, lower LOS and cost. TRIAL REGISTRATION Registration: www.

Abstract
(1) Background: Perioperative Antibiotics for acute complicated appendicitis are a standard of care. While there are plenty of trials for pediatric patients, data for elderly patients are scarce. The goal of our study was to evaluate whether elderly patients carry more resistant bacteria and thus have less favorable outcomes after an appendectomy that may warrant intensified perioperative antibiotic treatment (2) We present a retrospective single-center matched pair (139 patients each) analysis of perioperative and microbiological outcomes of an elderly appendicitis cohort (i.e., older than 60 years) compared with a younger adult cohort (i.e., ≤60 years). Both groups were matched one for one according to gender, duration of symptoms, c-reactive protein at presentation and whether they presented with uncomplicated or complicated appendicitis. (3) Results: After matching, complicated appendicitis was present in 76.3% of both groups. Elderly patients more frequently received preoperative diagnostic CT (p < 0.001) than the young. Both operative strategy (laparoscopic appendectomy in 92.1% each) and duration of surgery (57 vs. 56 min) were equal in both groups. Postoperative antibiotics were prescribed in ~57% for a median of 3 days in both groups and antibiotic selection was similar. The incidence of surgical site infections was higher in the young (12.2% vs. 7.9%) yet not significant. There was no difference in culture positivity or bacterial spectrum and the elderly cohort did not present with increased resistant bacterial isolates. (4) Conclusions: While overall resistant bacterial strains were rare, perioperative outcomes between the young and the elderly did not differ and did neither warrant longer nor intensified antibiotic treatment.

Abstract
A Deucalione, acute abdomen remains significant in abdominal pain. The entity of acute abdomen accounts for up to 10% of all emergency admissions. The differences between countries' income and level of prosperity are pertinent, particularly in terms of severity, radiological modalities, and surgical management of the condition. Of note, surgical modalities have been the most widely used treatment modality, and current evidence indicates that the laparoscopic approach, per se, is the most effective surgical therapy with a lower incidence of wound infection, post-intervention morbidity, shorter hospital stay, and better quality of life scores compared to the conventional method. In light of this, the present study aimed to evaluate ambulatory appendectomy in a series of sequential laparoscopic appendectomies (LApp), which included both complicated and uncomplicated cases.

Abstract
Background/Objective: Acute appendicitis (AA) is predominantly managed with appendectomy, but can be treated non-operatively, leading to a high risk of recurrence. Non-operative management has been more common since the COVID-19 pandemic affected the feasibility of performing surgery. This case-control study analyzed non-operatively managed patients in order to identify clinical and radiological factors associated with recurrence risk. Methods: Over 12 months, 48 adults with CT-proven AA managed non-operatively were identified, and followed up for at least six further months to assess them for recurrence (readmission to hospital more than 14 days after discharge and after symptom resolution, requiring treatment for appendicitis). Clinical and CT data were collected and a Cox regression survival analysis was performed to produce hazards ratios (HRs). Results: Of the 48 patients, 12 (25%) experienced a recurrence up until the end of the follow-up period, eight of whom were then treated operatively, and four treated non-operatively. On the univariate analysis, greater recurrence risk was observed in patients with diabetes mellitus, higher heart rate (on admission and maximum value during admission), lower white cell count and neutrophils and appendiceal wall thinning on CT. On the multivariate analysis, diabetes mellitus (HR=7.72, p=0.021) and higher heart rate (HR=1.08, p=0.018) were associated with statistically significant greater recurrence risk. Conclusions: Diabetes mellitus and higher heart rate on admission are associated with greater recurrence risk of AA managed non-operatively. No CT findings were associated with statistically significant greater risk. Clinicians should, therefore, consider DM and heart rate when making decisions on appendicitis management, especially during the COVID-19 pandemic but also beyond it.

Abstract
BACKGROUND AND OBJECTIVE The prevalence of bacteremia in acute appendicitis is unknown. We aimed to assess prevalence and predictive factors of bacteremia in adult patients with appendicitis. METHODS In this prospective propensity score-matched cohort study, patients were recruited as part of one single-center prospective observational study assessing appendicitis microbiology in concurrence with two randomized controlled trials on non-operative treatment of uncomplicated acute appendicitis. All patients evaluated for enrollment in these three trials between April 2017 and December 2018 with both a confirmed diagnosis of appendicitis and available blood culture on admission were included in this study. Potential predictive factors of bacteremia (age, sex, body mass index (BMI), body temperature, C-reactive protein (CRP), leukocyte count, comorbidities, symptom duration, and appendicitis severity) were assessed. Prevalence of bacteremia was determined by all available blood cultures followed by propensity score matching using sex, age, BMI, CRP, leukocyte count, and body temperature of the patients without available blood culture. RESULTS Out of the 815 patients with appendicitis, 271 patients had available blood culture and the prevalence of bacteremia was 12% (n = 33). Based on propensity score estimation, the prevalence of bacteremia in the whole prospective appendicitis cohort was 11.1%. Bacteremia was significantly more frequent in complicated acute appendicitis (15%; 29/189) compared with uncomplicated acute appendicitis (5%; 4/82) (p = 0.015). Male sex (p = 0.024) and higher body temperature (p = 0.0044) were associated with bacteremia. CONCLUSIONS Estimated prevalence of bacteremia in patients with acute appendicitis was 11.1%. Complicated appendicitis, male sex, and higher body temperature were associated with bacteremia in acute appendicitis.

Abstract
OBJECTIVE This study aims to compare the timing of interval appendectomy (IA) and its impact on post-operative outcomes. METHODS A retrospective analysis was performed for adult patients diagnosed with appendicitis between 2006 and 2017. IA was defined as a follow-up appendectomy > 1 week and < 2 years after the initial presentation. Time intervals were divided into 4 groups based on patient quartiles: 1-6 weeks, 7-9 weeks, 10-15 weeks, and > 15 weeks. The primary outcome measure was length of stay (LOS). Secondary outcomes included 30-day readmission and IA post-operative complications. Tertiary outcomes included 30-day mortality and colonoscopy suggesting neoplasm or Inflammatory Bowel Disease. RESULTS A total of 5069 patients' records whose interval appendectomy fell > 1 week and < 2 years after initial presentation were analyzed. Among them, 1006 (19.85%) underwent an initial percutaneous abscess drainage at diagnosis. The median timing for IA was 9.2 weeks. Patients with IA at 1-6 weeks were more likely to have longer LOS when compared to 7-9 weeks (ratio 1.33, 95% CI 1.2-1.48) and 10-15 weeks (ratio 1.38, 95% CI 1.25-1.52). IA between 7 and 9 weeks (ratio 0.81, 95% CI 0.73-0.89) and 10-15 weeks (ratio 0.78, 95% CI 0.71-0.86) was associated with significantly shorter LOS compared to those receiving the operation after 15 weeks. Further, patients requiring abscess drainage (ratio 1.2, 95% CI 1.13-1.34) or those with comorbidities (ratio 1.51, 95% CI 1.39-1.63) were more likely to have longer LOS at IA. Socioeconomic and demographic differences including Black, Hispanic, and those with Medicare and Medicaid insurance had a greater LOS after their IA. CONCLUSION LOS remains lowest among patients undergoing IA between 7-9 weeks and 10-15 weeks after initial appendicitis presentation. Patients with lower socioeconomic status or from racial minorities had a longer LOS after IA.
