Abstract
Background Recent randomized trials have suggested non-operative management to be a safe alternative to appendectomy for acute uncomplicated appendicitis. Yet, there remains significant variability in treatment approach. This study sought to characterize center-level variation in non-operative management within a national cohort of adults presenting with appendicitis. Methods The 2016-2020 Nationwide Readmissions Database was queried to identify all adult (≥18 years) hospitalizations for acute uncomplicated appendicitis. Hierarchical, mixed-effects models were developed to ascertain factors linked with non-operative management. Bayesian methodology was applied to predict random effects, which were then used to rank centers by increasing hospital-attributed rate of non-operative management. Institutions with high center-specific rates of non-operative management (>90th percentile) were considered low-operating hospitals (LOH). Results Of an estimated 447,500 patients, 52,523 (11.7 %) were managed non-operatively. Compared to those undergoing appendectomy, the non-operative cohort was older, more commonly male, and of a higher comorbidity burden. Approximately 30 % in the variability of non-operative management was attributable to hospital effects, with absolute, risk-adjusted rates ranging from 0.5 to 22.5 %. Centers with non-operative management rates ≥90th percentile were considered LOH.Following risk adjustment, among patients undergoing appendectomy, care at LOH was linked with greater odds of postoperative infection, resource utilization, and non-elective readmission. Conclusions We identified significant interhospital variation in the utilization of non-operative management for acute uncomplicated appendicitis. Further, we found LOH to be associated with inferior outcomes following surgical management. Future work is needed to assess the care pathways that contribute to increased utilization of non-operative strategies, and disseminate best practices across institutions.

Improving Accuracy of Administrative Data for Perforated Appendicitis Classification. J Surg Res 2024; 299:120-128. [PMID: 38749315 DOI: 10.1016/j.jss.2024.03.041] [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: 11/07/2023] [Revised: 02/06/2024] [Accepted: 03/22/2024] [Indexed: 06/22/2024]
Abstract
INTRODUCTION Reliance on International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes may misclassify perforated appendicitis with resultant research, fiscal, and public health implications. We aimed to improve the accuracy of administrative data for perforated appendicitis classification relying on ICD-10-CM codes from 2015 to 2018. METHODS We conducted a retrospective study of randomly sampled patients aged ≤18 years diagnosed with acute appendicitis from eight children's hospitals. Patients were identified using the Pediatric Health Information System, and true perforation status was determined by medical record review. We developed two algorithms by leveraging Pediatric Health Information System data elements and data mining (DM) approaches. The two developed algorithm performance was compared against algorithms that exclusively relied on ICD-10-CM codes using area under the curve and other measures. RESULTS Of 1051 clinically validated encounters that were included, 383 (36.4%) patients were identified to have perforated appendicitis. The two algorithms developed using DM approaches primarily leveraged ICD-10-CM codes and length of stay. DM-developed algorithms had a significantly higher accuracy than algorithms relying exclusively on ICD-10-CM (P value < 0.01): sensitivity and specificity for DM-developed algorithms were 0.86-0.88 and 0.95-0.97, respectively, which were overall higher than algorithms that relied on only ICD-10-CM. CONCLUSIONS This study provides an algorithm that can improve the accuracy of perforated appendicitis classification using commonly available elements in administrative data. We recommend that this algorithm is used in future appendicitis classification to ensure valid reporting, hospital-level benchmarking, and fiscal or public health assessments.

Abstract
Background Common postoperative complications following surgery, particularly acute appendicitis surgery, include postoperative pain and vomiting, which can cause discomfort and delay recovery time. Methods A randomized double-blinded placebo-controlled clinical trial was conducted with 80 cases of acute appendicitis of American Society of Anesthesiologists (ASA) physical status I or II and aged 18-60 y/o scheduled for appendectomy under general anesthesia. Patients were randomly divided into two equal groups: group A received 4 mg of ondansetron IV (2 ml) and group B received 2 ml of normal slain IV (placebo). Pain according to VAS, nausea and vomiting according to clinical symptoms, shivering and sedation according to the Bedside Shivering Assessment Scale (BSAS), and the Ramsay Sedation Scale (RSS) at 2, 6, 12, and 24 hours after surgery were evaluated and compared between the groups. Results There was a significant decline in the severity of pain only at 2 hours after surgery between the ondansetron and control groups (5.3 ± 1.0 vs. 6.0 ± 1.0; p=0.01), not showing a difference between the groups at 6, 12, and 24 hours after appendectomy. Postoperative nausea and vomiting at 2 (5% vs. 25%; p=0.03) and 6 (7.5% vs. 27.5%; p=0.04) hours after appendectomy in the ondansetron group. At different times, the ondansetron and control groups did not differ in terms of pethidine consumption or sedation. Conclusions In conclusion, our study found that ondansetron was effective in reducing postoperative vomiting after acute appendicitis surgery. However, it did not show a clinically significant effect on postoperative pain. This trial is registered with IRCT20230722058883N1.

Abstract
The identification of pediatric appendicitis is challenging due to the lack of specific markers thereby several factors are included in the diagnostic process such as abdominal pain, ultrasonography and altered laboratory parameters (C reactive protein, absolute neutrophil cell number and white blood cell number). The glycosylation pattern of serum N-glycome was analyzed in this study of 38 controls and 40 patients with pediatric appendicitis. The glycans were released by enzymatic deglycosylation followed by fluorescent labeling and solid-phase extraction. The prepared samples were analyzed by hydrophilic interaction liquid chromatography with fluorescence and mass-spectrometric detection. The generated data were analyzed by multiple statistical tests involving the most important laboratory parameters as well. Significant differences associated with the examined patient groups were revealed suggesting the potential use of glycosylation analysis supporting the detection of pediatric appendicitis.

Applying an explainable machine learning model might reduce the number of negative appendectomies in pediatric patients with a high probability of acute appendicitis. Sci Rep 2024; 14:12772. [PMID: 38834671 DOI: 10.1038/s41598-024-63513-x] [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: 12/28/2023] [Accepted: 05/29/2024] [Indexed: 06/06/2024] Open
Abstract
The diagnosis of acute appendicitis and concurrent surgery referral is primarily based on clinical presentation, laboratory and radiological imaging. However, utilizing such an approach results in as much as 10-15% of negative appendectomies. Hence, in the present study, we aimed to develop a machine learning (ML) model designed to reduce the number of negative appendectomies in pediatric patients with a high clinical probability of acute appendicitis. The model was developed and validated on a registry of 551 pediatric patients with suspected acute appendicitis that underwent surgical treatment. Clinical, anthropometric, and laboratory features were included for model training and analysis. Three machine learning algorithms were tested (random forest, eXtreme Gradient Boosting, logistic regression) and model explainability was obtained. Random forest model provided the best predictions achieving mean specificity and sensitivity of 0.17 ± 0.01 and 0.997 ± 0.001 for detection of acute appendicitis, respectively. Furthermore, the model outperformed the appendicitis inflammatory response (AIR) score across most sensitivity-specificity combinations. Finally, the random forest model again provided the best predictions for discrimination between complicated appendicitis, and either uncomplicated acute appendicitis or no appendicitis at all, with a joint mean sensitivity of 0.994 ± 0.002 and specificity of 0.129 ± 0.009. In conclusion, the developed ML model might save as much as 17% of patients with a high clinical probability of acute appendicitis from unnecessary surgery, while missing the needed surgery in only 0.3% of cases. Additionally, it showed better diagnostic accuracy than the AIR score, as well as good accuracy in predicting complicated acute appendicitis over uncomplicated and negative cases bundled together. This may be useful in centers that advocate for the conservative treatment of uncomplicated appendicitis. Nevertheless, external validation is needed to support these findings.

Abstract
INTRODUCTION Surgery for acute appendicitis has been associated with significant morbidity. This study aimed to determine the factors associated with early inhospital adverse outcomes following surgery for acute appendicitis in Uganda. METHODS This was a multicentre, prospective cohort in which early inhospital outcome following surgery for acute appendicitis was assessed at 4 regional referral hospitals in Uganda. The occurrence of complications during the admission period was documented as well as the length of hospital stay. Factors associated with adverse outcomes were determined using Poisson regression. RESULTS Of the 102 patients who underwent surgery for acute appendicitis, the majority were males 79(77.5%) with a mean age of 23.8(SD = 12.5) years. The perforated appendix was seen in 26 (25.5%) patients. Post-operative complications occurred in 21(20.6%) with the commonest being surgical site infection in 19(18.6%) patients. The median length of hospital stay was 3(IQR = 3-4) days with 43(42.2%) staying in hospital for more than 3 days. The presence of anemia (Hb < 8) (aRR = 1.376, CI = 1.159-1.634, P = < 0.001) and having a perforated appendix (aRR = 1.263, CI = 1.026-1.555, P = 0.027) were independently associated with occurrence of complications while being HIV positive (aRR = 1.379, CI = 1.105-1.721, P = 0.005) and having a perforated appendix (aRR = 1.258, CI = 1.019-1.554, P = 0.033) were independently associated with prolonged hospital stay. CONCLUSION Community education about early presentation is still required in order to reduce the number of patients that present late which should, in turn, reduce the risk of complications and length of hospital stay.

Abstract
BACKGROUND Application of artificial intelligence (AI) in general surgery is evolving. Real-world implementation of an AI-based computer-vision model in laparoscopic appendectomy (LA) is presented. We aimed to evaluate (1) its accuracy in complexity grading and safety adherence, (2) clinical correlation to outcomes. METHODS A retrospective single-center study of 499 consecutive LA videos, captured and analyzed by 'Surgical Intelligence Platform,' Theator Inc. (9/2020-5/2022). Two expert surgeons viewed all videos and manually graded complexity and safety adherence. Automated annotations were compared to surgeons' assessments. Inter-surgeons' agreements were measured. Since 7/2021 videos were linked to patients' admission numbers. Data retrieval from medical records was performed (n = 365). Outcomes were compared between high and low complexity grades. RESULTS Low and high complexity grades comprised 74.8 and 25.2% of 499 videos. Surgeons' agreements were high (76.9-94.4%, kappa 0.77/0.91; p < 0.001) for all annotated complexity grades. Surgeons' agreements were also high (96.0-99.8%, kappa 0.78/0.87; p < 0.001) for full safety adherence, whereas agreement was moderate in partial safety adherence and none (32.8-58.8%). Inter-surgeons' agreements were high for complexity grading (kappa 0.86, p < 0.001) and safety adherence (kappa 0.88, p < 0.001). Comparing high to low grade complexity, preoperative clinical features were similar, except larger appendix diameter on imaging (13.4 ± 4.4 vs. 10.5 ± 3.0 mm, p < 0.001). Intraoperative outcomes were significantly higher (p < 0.001), including time to achieve critical view of safety (29.6, IQR 19.1-41.6 vs. 13.7, IQR 8.5-21.1 min), operative duration (45.3, IQR 37.7-65.2 vs. 25.0, IQR 18.3-32.7 min), and intraoperative events (39.4% vs. 5.9%). Postoperative outcomes (7.4% vs. 9.2%) including surgical complications, mortality, and readmissions were comparable (p = 0.6), except length of stay (4, IQR 2-5.5 vs. 1, IQR 1-2 days; p < 0.001). CONCLUSION The model accurately assesses complexity grading and full safety achievement. It can serve to predict operative time and intraoperative course, whereas no clinical correlation was found regarding postoperative outcomes. Further studies are needed.

Surgery 2024; 175:1482-1488. [PMID: 38565493 DOI: 10.1016/j.surg.2024.02.020] [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: 11/24/2023] [Revised: 02/16/2024] [Accepted: 02/19/2024] [Indexed: 04/04/2024]
Abstract
BACKGROUND Appendicitis seems to be a disease of infectious origin, but the detailed pathogenesis is unknown. We aimed to investigate the microbiome of the appendix lumen in patients with and without appendicitis, including a comparison of the subgroups of complicated versus uncomplicated appendicitis. METHODS This prospective observational cohort study included adult patients undergoing laparoscopic appendectomy for suspected appendicitis. According to histopathologic findings, the investigated groups consisted of patients with and without appendicitis, including subgroups of complicated versus uncomplicated appendicitis based on the surgical report. A swab of the appendix lumen was analyzed for genetic material from bacteria with shotgun metagenomics, and outcomes included analyses of microbiome diversity and differential abundance of bacteria. RESULTS A total of 53 swabs from patients with suspected appendicitis were analyzed: 42 with appendicitis (16 complicated) and 11 without appendicitis. When comparing patients with and without appendicitis, they were equally rich in bacteria (alpha diversity), but the microbiome composition was dissimilar between these groups (beta diversity) (P < .01). No consistent bacterial species were detected in all patients with appendicitis, but a least 3 genera (Blautia, Faecalibacterium, and Fusicatenibacter) and 2 species, Blautia faecis and Blautia wexlerae, were more abundant in patients without appendicitis. For the subgroups complicated versus uncomplicated appendicitis, both measures for microbiome diversity were similar. CONCLUSION The appendix microbiome composition of genetic material from bacteria in adult patients with and without appendicitis differed, but the microbiome was similar for patients with complicated versus uncomplicated appendicitis. Trial registration NCT03349814.

Abstract
OBJECTIVES To validate the Atema and APSI scoring systems in the diagnosis of complicated vs uncomplicated appendicitis. To compare these scoring systems with computed tomography (CT) imaging alone to establish which method provides most accurate prediction of complicated vs uncomplicated appendicitis. METHODS This was a retrospective review of a sample of 160 patients that underwent appendicectomy and CT imaging for suspected appendicitis between 2018 and 2021 in a tertiary university teaching hospital. Each scoring system was applied to all patients and results analysed and compared with the effectiveness of CT imaging, RESULTS: 32.5% (n = 52) were found to have complicated appendicitis and 67.5% (n = 108) uncomplicated appendicitis. Application of the Atema score to our cohort of patients resulted in a sensitivity 76.9% [CI (64.2, 87.5), specificity 58.7% [CI (48.9, 68.1)], PPV 47.1% [CI (40.5, 53.8) and NPV 84.2% [CI (76.0, 89.9)]. By comparison, the APSI yielded a sensitivity 50.9% [CI (36.6, 65.4)], specificity 76.1% [CI (67.0, 87.8)], PPV 50% [CI (39.2, 60.6)] and NPV 76% [CI (71.1, 81.7)]. Radiology prediction of complicated vs uncomplicated appendicitis with CT imaging showed sensitivity 46% [CI (32.2, 60.5)], specificity 79%; [CI (69.8, 86)], PPV 51% [CI (39.6, 62.5)] and NPV 75% [CI (69.8, 79.9)]. CONCLUSION By comparing the APSI and Atema et al. scoring systems with CT reporting in our hospital, it appears that the Atema may confer some benefit in stratifying patient risk of complicated versus uncomplicated appendicitis. Further larger scale prospective studies are required.

Abstract
BACKGROUND This study aims to analyze the impact of the COVID-19 pandemic on the clinical, pathological, and surgical characteristics of acute appendicitis (AA) at the University Hospital Centre (UHC) Zagreb. METHODS This retrospective study analyzed demographic, clinical, and surgical data from consecutive AA patients. Data were collected from an electronic database for two periods: 1 January to 31 December 2019 (pre-COVID-19), and 11 March 2020, to 11 March 2021 (COVID-19 pandemic). RESULTS During the two study periods, 855 appendectomies were performed, 427 in the pre-pandemic, and 428 during the pandemic. Demographic data were comparable between groups. There was statistically no significant difference in the type of appendectomy (p = 0.33) and the median hospital length of stay (3; (2-5) days, p = 0.08). There was an increase in the conversion rate during the pandemic period (4.2% vs. 7.7%, p = 0.03). The negative appendectomy rate and the incidence of perforated AA did not differ significantly (p = 0.34 for both). CONCLUSIONS We did not observe a significant increase in the rate of AA complications during the COVID-19 pandemic at the UHC Zagreb. This may be attributed to two factors: (1) AA was diagnosed and treated as an emergency, which remained available during the pandemic, and (2) diagnostic and therapeutic protocols remained unaltered. We recommend a laparoscopic approach even during the COVID-19 pandemic.

Abstract
BACKGROUND This is an update of a Cochrane review first published in 2017. Acute appendicitis (inflammation of the appendix) can be simple or complicated. Appendiceal phlegmon and appendiceal abscess are examples of complicated appendicitis. Appendiceal phlegmon is a diffuse inflammation in the bottom right of the appendix, while appendiceal abscess is a discrete inflamed mass in the abdomen that contains pus. Appendiceal phlegmon and abscess account for 2% to 10% of acute appendicitis. People with appendiceal phlegmon or abscess usually need an appendicectomy to relieve their symptoms (e.g. abdominal pain, loss of appetite, nausea, and vomiting) and avoid complications (e.g. peritonitis (infection of abdominal lining)). Surgery for people with appendiceal phlegmon or abscess may be early (immediately after hospital admission or within a few days of admission), or delayed (several weeks later in a subsequent hospital admission). The optimal timing of appendicectomy for appendiceal phlegmon or abscess is debated. OBJECTIVES To assess the effects of early appendicectomy compared to delayed appendicectomy on overall morbidity and mortality in people with appendiceal phlegmon or abscess. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, two other databases, and five trials registers on 11 June 2023, together with reference checking to identify additional studies. SELECTION CRITERIA We included all individual and cluster-randomised controlled trials (RCTs), irrespective of language, publication status, or age of participants, comparing early versus delayed appendicectomy in people with appendiceal phlegmon or abscess. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included eight RCTs that randomised 828 participants to early or delayed appendicectomy for appendiceal phlegmon (7 trials) or appendiceal abscess (1 trial). The studies were conducted in the USA, India, Nepal, and Pakistan. All RCTs were at high risk of bias because of lack of blinding and lack of published protocols. They were also unclear about methods of randomisation and length of follow-up. 1. Early versus delayed open or laparoscopic appendicectomy for appendiceal phlegmon We included seven trials involving 788 paediatric and adult participants with appendiceal phlegmon: 394 of the participants were randomised to the early appendicectomy group (open or laparoscopic appendicectomy as soon as the appendiceal mass resolved within the same admission), and 394 were randomised to the delayed appendicectomy group (initial conservative treatment followed by delayed open or laparoscopic appendicectomy several weeks later). There was no mortality in either group. The evidence is very uncertain about the effect of early appendicectomy on overall morbidity (risk ratio (RR) 0.74, 95% confidence interval (CI) 0.19 to 2.86; 3 trials, 146 participants; very low-certainty evidence), the proportion of participants who developed wound infections (RR 0.99, 95% CI 0.48 to 2.02; 7 trials, 788 participants), and the proportion of participants who developed faecal fistulas (RR 1.75, 95% CI 0.36 to 8.49; 5 trials, 388 participants). Early appendicectomy may reduce the abdominal abscess rate (RR 0.26, 95% CI 0.08 to 0.80; 4 trials, 626 participants; very low-certainty evidence), reduce the total length of hospital stay by about two days (mean difference (MD) -2.02 days, 95% CI -3.13 to -0.91; 5 trials, 680 participants), and increase the time away from normal activities by about five days (MD 5.00 days; 95% CI 1.52 to 8.48; 1 trial, 40 participants), but the evidence is very uncertain. 2. Early versus delayed laparoscopic appendicectomy for appendiceal abscess We included one trial involving 40 paediatric participants with appendiceal abscess: 20 were randomised to the early appendicectomy group (emergent laparoscopic appendicectomy), and 20 were randomised to the delayed appendicectomy group (initial conservative treatment followed by delayed laparoscopic appendicectomy 10 weeks later). There was no mortality in either group. The trial did not report on overall morbidity, various complications, or time away from normal activities. The evidence is very uncertain about the effect of early appendicectomy on the total length of hospital stay (MD -0.20 days, 95% CI -3.54 to 3.14; very low-certainty evidence). AUTHORS' CONCLUSIONS For the comparison of early versus delayed open or laparoscopic appendicectomy for paediatric and adult participants with appendiceal phlegmon, very low-certainty evidence suggests that early appendicectomy may reduce the abdominal abscess rate. The evidence is very uncertain whether early appendicectomy prevents overall morbidity or other complications. Early appendicectomy may reduce the total length of hospital stay and increase the time away from normal activities, but the evidence is very uncertain. For the comparison of early versus delayed laparoscopic appendicectomy for paediatric participants with appendiceal abscess, data are sparse, and we cannot rule out significant benefits or harms of early versus delayed appendicectomy. Further trials on this topic are urgently needed and should specify a set of criteria for use of antibiotics, percutaneous drainage of the appendiceal abscess prior to surgery, and resolution of the appendiceal phlegmon or abscess. Future trials should include outcomes such as time away from normal activities and length of hospital stay.

Abstract
OBJECTIVE To compare costs for 2 days versus 5 days of postoperative antibiotics within the antibiotics after an aPPendectomy In Complex appendicitis trial.Background:Recent studies suggest that restrictive antibiotic use leads to a significant reduction in hospital stays without compromising patient safety. Its potential effect on societal costs remains underexplored. METHODS This was a pragmatic, open-label, multicenter clinical trial powered for noninferiority. Patients with complex appendicitis (age ≥ 8 years) were randomly allocated to 2 days or 5 days of intravenous antibiotics after appendectomy. Patient inclusion lasted from June 2017 to June 2021 in 15 Dutch hospitals. The final follow-up was on September 1, 2021. The primary trial endpoint was a composite endpoint of infectious complications and mortality within 90 days. In the present study, the main outcome measures were overall societal costs (comprising direct health care costs and costs related to productivity loss) and cost-effectiveness. Direct health care costs were recorded based on data in the electronic patient files, complemented by a telephone follow-up at 90 days. In addition, data on loss of productivity were acquired through the validated Productivity Cost Questionnaire at 4 weeks after surgery. Cost estimates were based on prices for the year 2019. RESULTS In total, 1005 patients were evaluated in the "intention-to-treat" analysis: 502 patients were allocated to the 2-day group and 503 to the 5-day group. The mean difference in overall societal costs was - €625 (95% CI: -€ 958 to -€ 278) to the advantage of the 2-day group. This difference was largely explained by reduced hospital stay. Productivity losses were similar between the study groups. Restricting postoperative antibiotics to 2 days was cost-effective, with estimated cost savings of €31,117 per additional infectious complication. CONCLUSIONS Two days of postoperative antibiotics for complex appendicitis results in a statistically significant and relevant cost reduction, as compared with 5 days. Findings apply to laparoscopic appendectomy in a well-resourced health care setting.

Abstract
BACKGROUND Acute appendicitis is one of the most common emergency general surgical conditions worldwide. Uncomplicated/simple appendicitis can be treated with appendectomy or antibiotics. Some studies have suggested possible benefits with antibiotics with reduced complications, length of hospital stay, and the number of days off work. However, surgery may improve success of treatment as antibiotic treatment is associated with recurrence and future need for surgery. OBJECTIVES To assess the effects of antibiotic treatment for uncomplicated/simple acute appendicitis compared with appendectomy for resolution of symptoms and complications. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, and two trial registers (World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov) on 19 July 2022. We also searched for unpublished studies in conference proceedings together with reference checking and citation search. There were no restrictions on date, publication status, or language of publication. SELECTION CRITERIA We included parallel-group randomised controlled trials (RCTs) only. We included studies where most participants were adults with uncomplicated/simple appendicitis. Interventions included antibiotics (by any route) compared with appendectomy (open or laparoscopic). DATA COLLECTION AND ANALYSIS We used standard methodology expected by Cochrane. We used GRADE to assess the certainty of evidence for each outcome. Primary outcomes included mortality and success of treatment, and secondary outcomes included number of participants requiring appendectomy in the antibiotic group, complications, pain, length of hospital stay, sick leave, malignancy in the antibiotic group, negative appendectomy rate, and quality of life. Success of treatment definitions were heterogeneous although mainly based on resolution of symptoms rather than incorporation of long-term recurrence or need for surgery in the antibiotic group. MAIN RESULTS We included 13 studies in the review covering 1675 participants randomised to antibiotics and 1683 participants randomised to appendectomy. One study was unpublished. All were conducted in secondary care and two studies received pharmaceutical funding. All studies used broad-spectrum antibiotic regimens expected to cover gastrointestinal bacteria. Most studies used predominantly laparoscopic surgery, but some included mainly open procedures. Six studies included adults and children. Almost all studies aimed to exclude participants with complicated appendicitis prior to randomisation, although one study included 12% with perforation. The diagnostic technique was clinical assessment and imaging in most studies. Only one study limited inclusion by sex (male only). Follow-up ranged from hospital admission only to seven years. Certainty of evidence was mainly affected by risk of bias (due to lack of blinding and loss to follow-up) and imprecision. Primary outcomes It is uncertain whether there was any difference in mortality due to the very low-certainty evidence (Peto odds ratio (OR) 0.51, 95% confidence interval (CI) 0.05 to 4.95; 1 study, 492 participants). There may be 76 more people per 1000 having unsuccessful treatment in the antibiotic group compared with surgery, which did not reach our predefined level for clinical significance (risk ratio (RR) 0.91, 95% CI 0.87 to 0.96; I2 = 69%; 7 studies, 2471 participants; low-certainty evidence). Secondary outcomes At one year, 30.7% (95% CI 24.0 to 37.8; I2 = 80%; 9 studies, 1396 participants) of participants in the antibiotic group required appendectomy or, alternatively, more than two-thirds of antibiotic-treated participants avoided surgery in the first year, but the evidence is very uncertain. Regarding complications, it is uncertain whether there is any difference in episodes of Clostridium difficile diarrhoea due to very low-certainty evidence (Peto OR 0.97, 95% CI 0.24 to 3.89; 1 study, 1332 participants). There may be a clinically significant reduction in wound infections with antibiotics (RR 0.25, 95% CI 0.09 to 0.68; I2 = 16%; 9 studies, 2606 participants; low-certainty evidence). It is uncertain whether antibiotics affect the incidence of intra-abdominal abscess or collection (RR 1.58, 95% CI 0.61 to 4.07; I2 = 19%; 6 studies, 1831 participants), or reoperation (Peto OR 0.13, 95% CI 0.01 to 2.16; 1 study, 492 participants) due to very low-certainty evidence, mainly due to rare events causing imprecision and risk of bias. It is uncertain if antibiotics prolonged length of hospital stay by half a day due to the very low-certainty evidence (MD 0.54, 95% CI 0.06 to 1.01; I2 = 97%; 11 studies, 3192 participants). The incidence of malignancy was 0.3% (95% CI 0 to 1.5; 5 studies, 403 participants) in the antibiotic group although follow-up was variable. Antibiotics probably increased the number of negative appendectomies at surgery (RR 3.16, 95% CI 1.54 to 6.49; I2 = 17%; 5 studies, 707 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS Antibiotics may be associated with higher rates of unsuccessful treatment for 76 per 1000 people, although differences may not be clinically significant. It is uncertain if antibiotics increase length of hospital stay by half a day. Antibiotics may reduce wound infections. A third of the participants initially treated with antibiotics required subsequent appendectomy or two-thirds avoided surgery within one year, but the evidence is very uncertain. There were too few data from the included studies to comment on major complications.

Abstract
BACKGROUND We investigated the impact of the COVID-19 pandemic on trends of presentation, management and pathology findings in patients who underwent an appendicectomy for suspected acute appendicitis. METHOD The retrospective study reviewed patients (n = 939 adults and n = 329 children) who had an appendicectomy performed for suspected acute appendicitis and histopathology assessment in the Belfast Health and Social Care Trust, Northern Ireland. Pre-COVID-19 (March 2019 to February 2020) and COVID-19 Year 1 (March 2020 to February 2021) data were compared. Chi-squared tests were applied to compare timeframes. RESULTS 513 adult appendicectomies were performed in the immediate year pre-COVID-19, compared to 426 in COVID-19 Year 1, representing a 17% reduction. No such reduction was seen within the paediatric population, likely related to a change in regional paediatric referral criteria during the pandemic. When comparing COVID-19 Year 1 with pre-pandemic, fewer patients presented with <24 hours of symptoms (45% v 53%, p = 0.005), and there was greater use of pre-operative computed tomography imaging in adults (63.2% v 48.7%, p<0.001). Fewer adult and paediatric cases of simple acute appendicitis and non-diagnostic specimens, with relative increased proportions of perforated acute appendicitis, were observed in COVID-19 Year 1 compared with pre-pandemic. No absolute increase in perforated acute appendicitis cases was observed in adults. CONCLUSION Year 1 of the COVID-19 pandemic was associated with delayed presentation of acute appendicitis in adults and children. In adults, an overall reduction in appendicectomy operations, increased use of pre-operative diagnostic imaging, and fewer specimens showing simple acute appendicitis or non-diagnostic features, collectively support appropriate restriction of surgery for those patients with a more certain acute appendicitis diagnosis.

Abstract
BACKGROUND Conventional three-access laparoscopic appendectomy (CLA) is currently the gold standard treatment, however, Single-Port Laparoscopic Appendectomy (SILA) has been proposed as an alternative. The aim of this systematic review/meta-analysis was to evaluate safety and efficacy of SILA compared with conventional approach. METHODS Per PRISMA guidelines, we systematically reviewed randomised controlled trials (RCTs) comparing CLA vs SILA for acute appendicitis. The randomised Mantel-Haenszel method was used for the meta-analysis. Statistical data analysis was performed with the Review Manager software and the risk of bias was assessed with the Cochrane "Risk of Bias" assessment tool. RESULTS Twenty-one studies (RCTs) were selected (2646 patients). The operative time was significantly longer in the SILA group (MD = 7,32), confirmed in both paediatric (MD = 9,80), (Q = 1,47) and adult subgroups (MD = 5,92), (Q = 55,85). Overall postoperative morbidity was higher in patients who underwent SILA, but the result was not statistically significant. In SILA group were assessed shorter hospital stays, fewer wound infections and higher conversion rate, but the results were not statistically significant. Meta-analysis was not performed about cosmetics of skin scars and postoperative pain because different scales were used in each study. CONCLUSIONS This analysis show that SILA, although associated with fewer postoperative wound infection, has a significantly longer operative time. Furthermore, the risk of postoperative general complications is still present. Further studies will be required to analyse outcomes related to postoperative pain and the cosmetics of the surgical scar.

Abstract
INTRODUCTION Diverticulitis and appendicitis are common emergency general surgical conditions. Both can be treated with antibiotics alone; however, no antibiotic regimen has been identified as superior to others. In this study, we review different antibiotic regimens and their rates of failure. METHODS Retrospective cohort study of patients treated empirically with antibiotics for diverticulitis or appendicitis from January 1, 2018, to December 31, 2020, at an independent academic hospital in the Midwest. RESULTS A total of 587 (appendicitis, n = 43; diverticulitis, n = 544) patients were included in the cohort. They were equally male (49%) and female (51%) with a median age of 59 y. Three major antibiotic classes were compared: cephalosporin + metronidazole (C + M), penicillins, and quinolone + metronidazole. Appendicitis patients were more likely to receive C + M for empiric treatment (73%, P < 0.001), while diverticulitis patients were more likely to receive quinolone + metronidazole (45%, P < 0.001). Patients empirically treated with antibiotics for appendicitis were more likely than those treated for diverticulitis to require additional antibiotics or procedure within 90 d (33% versus 13%, respectively; P = 0.005). Empiric treatment with C + M for diverticulitis was more likely to be associated with the need for additional antibiotics or procedures within 90 d than treatment with other regimens (P = 0.003). Choice of antibiotic for empiric treatment did not correlate with death at 90 d for appendicitis or diverticulitis. Diverticulitis patients who were initially treated as inpatients and were prescribed C + M at hospital discharge had a higher rate of death than those who were prescribed the other antibiotics (P = 0.04). CONCLUSIONS Empiric antibiotic treatment of appendicitis is more likely to be associated with additional antibiotics or procedure when compared with diverticulitis; however, antibiotic choice did not correlate with any of the other outcomes. Empiric treatment with a C + M for diverticulitis was more likely to be correlated with the need for additional antibiotics or procedure within 90 d.

Abstract
RATIONALE AND OBJECTIVES This study aimed to develop and validate a deep learning and radiomics combined model for differentiating complicated from uncomplicated acute appendicitis (AA). MATERIALS AND METHODS This retrospective multicenter study included 1165 adult AA patients (training cohort, 700 patients; validation cohort, 465 patients) with available abdominal pelvic computed tomography (CT) images. The reference standard for complicated/uncomplicated AA was the surgery and pathology records. We developed our combined model with CatBoost based on the selected clinical characteristics, CT visual features, deep learning features, and radiomics features. We externally validated our combined model and compared its performance with that of the conventional combined model, the deep learning radiomics (DLR) model, and the radiologist's visual diagnosis using receiver operating characteristic (ROC) curve analysis. RESULTS In the training cohort, the area under the ROC curve (AUC) of our combined model in distinguishing complicated from uncomplicated AA was 0.816 (95% confidence interval [CI]: 0.785-0.844). In the validation cohort, our combined model showed robust performance across the data from three centers, with AUCs of 0.836 (95% CI: 0.785-0.879), 0.793 (95% CI: 0.695-0.872), and 0.723 (95% CI: 0.632-0.802). In the total validation cohort, our combined model (AUC = 0.799) performed better than the conventional combined model, DLR model, and radiologist's visual diagnosis (AUC = 0.723, 0.755, and 0.679, respectively; all P < 0.05). Decision curve analysis showed that our combined model provided greater net benefit in predicting complicated AA than the other three models. CONCLUSION Our combined model allows the accurate differentiation of complicated and uncomplicated AA.

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
INTRODUCTION Appendiceal neoplasms (ANs) are rare, with an estimated incidence of around 1%: neuroendocrine tumours (NETs) and low-grade appendiceal mucinous neoplasms (LAMNs) comprise most cases. Most tumours are cured by appendectomy alone, although some require right hemicolectomy and intra-operative chemotherapy. The aim of the present study is to evaluate our institution's experience in terms of the prevalence of AN, their histological types, treatment and outcomes in adult patients undergoing emergency appendectomy. MATERIAL AND METHODS Single-centre retrospective cohort analysis of patients treated for acute appendicitis at a large academic medical centre. Patients with a diagnosis of acute appendicitis (AA) where further compared with patients with acute appendicitis and a histologically confirmed diagnosis of appendiceal neoplasm (AN). RESULTS A diagnosis of acute appendicitis was made in 1200 patients. Of these, 989 patients underwent emergency appendectomy. The overall incidence of appendiceal neoplasm was 9.3% (92 patients). AN rate increased with increasing age. Patients under the age of 30 had a 3.8% (14/367 patients) rate of occult neoplasm, whereas patients between 40 and 89 years and older had a 13.0% rate of neoplasm. No difference was found in clinical presentations and type of approach while we found a lower complicated appendicitis rate in the AN group. CONCLUSION ANs are less rare with respect to the literature; however, clinically, there are no specific signs of suspicious and simple appendicectomy appears to be curative in most cases. However, age plays an important role; older patients are at higher risk for AN. ANs still challenge the non-operative management concept introduced into the surgical literature.

Abstract
BACKGROUND Appendicitis is one of the most common pathologies encountered by general and acute care surgeons. The current literature is inconsistent, as it is fraught with outcome heterogeneity, especially in the area of nonoperative management. We sought to develop a core outcome set (COS) for future appendicitis studies to facilitate outcome standardization and future data pooling. METHODS A modified Delphi study was conducted after identification of content experts in the field of appendicitis using both the Eastern Association for the Surgery of Trauma (EAST) landmark appendicitis articles and consensus from the EAST ad hoc COS taskforce on appendicitis. The study incorporated three rounds. Round 1 utilized free text outcome suggestions, then in rounds 2 and 3 the suggests were scored using a Likert scale of 1 to 9 with 1 to 3 denoting a less important outcome, 4 to 6 denoting an important but noncritical outcome, and 7 to 9 denoting a critically important outcome. Core outcome status consensus was defined a priori as >70% of scores 7 to 9 and <15% of scores 1 to 3. RESULTS Seventeen panelists initially agreed to participate in the study with 16 completing the process (94%). Thirty-two unique potential outcomes were initially suggested in round 1 and 10 (31%) met consensus with one outcome meeting exclusion at the end of round 2. At completion of round 3, a total of 17 (53%) outcomes achieved COS consensus. CONCLUSION An international panel of 16 appendicitis experts achieved consensus on 17 core outcomes that should be incorporated into future appendicitis studies as a minimum set of standardized outcomes to help frame future cohort-based studies on appendicitis. LEVEL OF EVIDENCE Diagnostic Test or Criteria; Level V.

Abstract
BACKGROUND Despite being a commonly performed surgical procedure, pain management for appendicectomy is often neglected because of insufficient evidence on the most effective treatment options. OBJECTIVE To provide evidence-based recommendations by assessing the available literature for optimal pain management after appendicectomy. DESIGN AND DATA SOURCES This systematic review-based guideline was conducted according to the PROSPECT methodology. Relevant randomised controlled trials, systematic reviews and meta-analyses in the English language from January 1999 to October 2022 were retrieved from MEDLINE, Embase and Cochrane Databases using PRISMA search protocols. ELIGIBILITY CRITERIA We included studies on adults and children. If articles reported combined data from different surgeries, they had to include specific information about appendicectomies. Studies needed to measure pain intensity using a visual analogue scale (VAS) or a numerical rating scale (NRS). Studies that did not report the precise appendicectomy technique were excluded. RESULTS Out of 1388 studies, 94 met the inclusion criteria. Based on evidence and consensus, the PROSPECT members agreed that basic analgesics [paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs)] should be administered perioperatively for open and laparoscopic appendicectomies. A laparoscopic approach is preferred because of lower pain scores. Additional recommendations for laparoscopic appendicectomies include a three-port laparoscopic approach and the instillation of intraperitoneal local anaesthetic. For open appendicectomy, a preoperative unilateral transverse abdominis plane (TAP) block is recommended. If not possible, preincisional infiltration with local anaesthetics is an alternative. Opioids should only be used as rescue analgesia. Limited evidence exists for TAP block in laparoscopic appendicectomy, analgesic adjuvants for TAP block, continuous wound infiltration after open appendicectomy and preoperative ketamine and dexamethasone. Recommendations apply to children and adults. CONCLUSION This review identified an optimal analgesic regimen for open and laparoscopic appendicectomy. Further randomised controlled trials should evaluate the use of regional analgesia and wound infiltrations with adequate baseline analgesia, especially during the recommended conventional three-port approach. REGISTRATION The protocol for this study was registered with the PROSPERO database (Registration No. CRD42023387994).

PARTICIPANTS Adult patients who underwent appendectomy via a lower-right-quadrant abdominal incision due to complicated appendicitis. METHODS A secondary analysis of a published RCT was performed applying a counterfactual prediction model considering interventions (PC vs DPC) and other significant predictors. A multivariable logistic regression was applied, and a likelihood-ratio test was used to select significant predictors to retain in a final model. Factual versus counterfactual SSI risks for individual patients along with individual treatment effect (iTE) were estimated. RESULTS In total, 546 patients (271 PC vs 275 DPC) were included in the analysis. The individualized prediction model consisted of allocated intervention, diabetes, type of complicated appendicitis, fecal contamination, and incision length. The iTE varied between 0.4% and 7% for PC compared to DPC; ∼38.1% of patients would have ≥2.1% lower SSI risk following PC compared to DPC. The greatest risk reduction was identified in diabetes with ruptured appendicitis, fecal contamination, and incision length of 10 cm, where SSI risks were 47.1% and 54.1% for PC and DPC, respectively. CONCLUSIONS In this secondary analysis, we found that most patients benefited from early PC versus DPC. Findings may be used to inform SSI prevention strategies for patients with complicated appendicitis.

Abstract
Introduction and importance Cecal foreign bodies are uncommon causes of acute abdomen, and their presentation can often mimic acute appendicitis (AA), making it challenging to diagnose. The authors present the case of a 12-year-old male from Ethiopia who initially presented with symptoms suggestive of AA. However, during surgery, the authors found a multiple magnetic fields result in perforation. This case highlights the importance of considering unusual etiologies. Case presentation A 12-year-old boy with AA associated with anorexia, nausea, and low-grade fever was referred from a private clinic. Otherwise, no history of recent respiratory infection and diarrhea, and was previously in good health. The patient did not report any history of a foreign body (FB), even to his own family, and, except for himself, no one was aware of the ingested FB. The work has been reported in line with the Surgical CAse REport (SCARE) 2023 criteria. Discussion In this case, the authors experienced multiple magnetic FB in the cecum, which were not observed on ultrasound (U/S). However, this case closely resembled appendicitis. U/S can aid in differentiation. However, it may not always identify the underlying etiology, specifically in a resource-limited setting. Conclusion Based on the patient's presentation, AA was diagnosed and emergency surgery was presumed to be inflamed. However, three magnetic FB were the underlying cause of the presentation, which created pressure on the cecal wall, and the authors successfully performed surgical management. This case reminds us of uncommon etiologies, such as magnets in patients with symptoms of appendicitis. This underscores the importance of an open-minded approach to unexpected findings during surgery.

Abstract
BACKGROUND The objective of this study was to assess the likelihood of acute appendicitis (AA) in children presenting with abdominal symptoms at the emergency department (ED), based on their prior primary care (PC) consultation history. METHODS Between February and June 2021, we prospectively enrolled all children presenting at the ED with acute abdominal pain indicative of possible acute appendicitis (AA). Subsequently, they were categorized into three groups: those assessed by a PC physician (PG), those brought in by their family without a prior consultation (FG), and those admitted after a PC consultation without being assessed as such. The primary objective was to assess the probability of AA diagnosis using the Pediatric Appendicitis Score (PAS). Secondary objectives included analyzing PAS and C-reactive protein (CRP) levels based on the duration of pain and final diagnoses. RESULTS 124 children were enrolled in the study (PG, n = 56; FG, n = 55; NG, n = 13). Among them, 29 patients (23.4%) were diagnosed with AA, with 13 cases (23.2%) from the PG and 14 cases (25.4%) from the FG. The mean PAS scores for AA cases from the PG and FG were 6.69 ± 1.75 and 7.57 ± 1.6, respectively, (p = 0.3340). Both PAS scores and CRP levels showed a significant correlation with AA severity. No cases of AA were observed with PAS scores < 4. CONCLUSIONS There was no significant difference in PAS scores between patients addressed by PG and FG, even though PAS scores tended to be higher for patients with AA. We propose a new decision-making algorithm for PC practice, which incorporates inflammatory markers and pain duration.

Abstract
An uncomplicated appendectomy in children is common. Safely minimizing the post-operative length of stay is desirable from hospital, patient, and parent perspectives. In response to an overly long mean length of stay following uncomplicated appendectomies in children of 2.5 days, we developed clinical pathways with the goal of safely reducing this time to 2.0 or fewer days. The project was conducted in an urban, academic children's hospital. The pathways emphasized the use of oral, non-narcotic pain medications; the education of parents and caregivers about expectations regarding pain control, oral food intake, and mobility; and the avoidance of routine post-operative antibiotic use. A convenience sample of 46 patients aged 3-16 years old was included to evaluate the safety and efficacy of the intervention. The mean post-operative length of stay was successfully reduced by 80% to 0.5 days without appreciable complications associated with earlier discharge. The hospital length of stay following an uncomplicated appendectomy in children may be successfully and safely reduced through the use of carefully devised, well-defined, well-disseminated clinical pathways.

Abstract
Patients with complicated appendicitis have an increased risk for postoperative infections. Potential risk factors for postoperative infections through a meta-analysis and retrospective chart review are discussed. A meta-analysis consisting of 35 studies analyzing complicated appendicitis treated with an appendectomy noting at least 1 postoperative infection was performed. A retrospective review was then conducted in patients diagnosed with complicated appendicitis after appendectomy. Of 5326 patients in total, 15.4% developed postoperative infections. Laparoscopic surgery and perioperative hyperoxygenation were found to be protective factors for the development of infection. Retrospectively, 53.2% of patients presented with complicated appendicitis. Patients with complicated appendicitis were more likely to be older in age and have an increased length of stay. Patient demographics, operative time, and comorbid status had no effect on postoperative infection or readmission rate. Physicians should strongly consider minimally invasive techniques to treat all cases of complicated appendicitis irrespective of comorbidities, age, sex, or body mass index.

Abstract
INTRODUCTION With it becoming a global pandemic, the coronavirus disease of 2019 (COVID-19) imposed public health restraints that hampered patient's presentation to hospitals. In Lebanon, little is known about the presentation patterns of acute appendicitis (AA) patients among different population groups during the COVID-19. Therefore, this study aims to assess the effects of the COVID-19 pandemic on the rates of cases seen during the pandemic period, the adopted management strategies, and evaluate the patient outcomes compared to presentations from previous years. METHODS This is a retrospective, observational cohort study with no interventional procedures. All patients presented to our tertiary health care center were diagnosed with AA between February 2019 and February 2021 comprised the study analysis. We divided our patients into the pre-pandemic period cohort March 1st, 2019, till February 29th, 2020, and the pandemic period cohort March 1st 2020 till March 1st 2021. RESULTS We collected data retrospectively from 342 patients: 201 patients presented in the pre-pandemic period and 141 during the pandemic period. Male predominance was seen in both cohorts (51.7% and 58.9% respectively). A decrease in the number of AA cases was seen during the pandemic, however, the duration of symptoms before presentation was similar in both cohorts (p = 0.382) Additionally, the number of complicated appendicitis cases was not different between cohorts. The main imaging modality was CT in both groups with no statistically significant difference in the type of imaging between them (p = 0.398). Further, the predominant treatment modality remained surgery during the pandemic, with no difference between both periods (p = 0.200), and no statistically significant difference in the type of surgery performed as laparoscopic surgery remained the most common surgery type in the pandemic period (p = 0.43). Finally, no extra surgical and post-surgical complications were identified. CONCLUSION In conclusion, our study is an example of how the COVID-19 pandemic did not significantly affect patients presenting for AA. Despite the COVID-19-related restrictions, Lebanese patients with worrying symptoms were presenting to the emergency department and the American University of Beirut Medical Center was providing them with the standards of care. Our study mirrors the Lebanese experience and gives an example of a population that focused more on their current symptoms than the fear of acquiring the COVID-19 virus. Further research is needed to assess whether this was the correct approach during these times.

Abstract
Acute appendicitis is a common surgical emergency. Complicated appendicitis usually warrants perioperative antibiotic treatment in order to prevent infectious complications. Whether routine microbiological testing benefits the individual patient is a topic of debate. The goal of our study was to assess perioperative antibiotic prescriptions as well as the benefit of microbiological testing during the appendectomy as a predictor for bacteria encountered in infectious complications. This is a retrospective analysis of 1218 consecutive patients that underwent appendectomy at a tertiary referral center between 2014 and 2021. The patient charts were systematically analyzed regarding intraoperative outcome, microbiologic results, and postoperative infectious complications. 1218 patients were included in this study of which 768 were uncomplicated appendicitis (UA) and 450 were complicated appendicitis (CA). Microbiological testing was performed in 39.2% of UA cases (33.6% of which grew bacteria) compared to 74.9% of CA cases (78.6% positive cultures). The strongest individual predictors for SSI were gangrenous and perforated appendicitis. A total of 58 surgical-site infections developed, of which 49 were intra-abdominal fluid collections or abscesses. Thirty-two patients had revision surgery or CT-guided drainage for SSI. In the cases where microbiological testing was done both during the appendectomy and the SSI, 13/18 showed different bacteria on culture testing. The infectious outcome was favorable in 98.3%. While microbiological testing offers insights into resistance patterns, it is of little benefit for the individual patient, given the low predictive value for bacteria found during SSI. Achieving source control combined with empiric antibiotic coverage leads to favorable outcomes independent of culture results.

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
Purpose The aim of this study is to investigate the factors influencing hospitalization costs for patients diagnosed with acute appendicitis in China. Methods We conducted a cross-sectional study using data from Provincial Health Statistics Support System Database from S Province in China. This dataset contained all hospital's electronic medical records from January 1, 2015 to December 31, 2018 including both public and private hospitals. The target population was identified based on the principal diagnosis of appendicitis (ICD-10: K35). To examine the impact of various factors on hospitalization costs, we conducted a multivariate linear regression analysis. Furthermore, we employed the Shapley value decomposition method to gain a more comprehensive understanding of the factors that influenced hospitalization costs and their respective levels of importance. Results Our study comprised 317,200 cases. During the period from 2015 to 2018, the average hospitalization expenses for patients with acute appendicitis were estimated at approximately 7014 RMB (1061 USD), which accounts for a considerable 12% of China's per capita GDP. The results of this study demonstrate a significant correlation between various factors, such as the patient's age, gender, marital status, occupation, payment method, number of complications, treatment method, hospital tier, and ownership, and the total hospitalization costs and subcomponents of hospitalization costs. Notably, the treatment method employed had the most substantial impact on hospitalization costs. Conclusion To the best of knowledge, this is one of the first studies to investigate the hospitalization costs of acute appendicitis incorporating both patient-level and hospital-level covariates, using a large sample size. To reduce the costs associated with acute appendicitis in China, it is recommended to consider suitable treatment options and explore the option of receiving medical care at lower-tier and privately-owned healthcare facilities.

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
Introduction Acute appendicitis is one of the common causes of acute abdomen in adults, which is managed widely with appendicectomy. Neuroendocrine tumours are the most common appendiceal tumours diagnosed incidentally on appendicectomy specimens. Methods Demographic data, presenting complaints, indications for appendicectomy, and the histology findings based on histopathological reports of the patients who have undergone appendicectomy for appendicitis at surgical units of Teaching Hospital, Jaffna, from 1st of January 2019 to 31st of December 2022 were retrospectively analyzed. Results Of the 1341 histopathology reports, 0.2% (n=3) were neuroendocrine tumours (NET). The mean age of the patients with NET was 48.6, and 66.6% of them were females. All three NETs identified in appendicectomy specimens were well differentiated and smaller than 2 cm. All three had negative resection margins and were managed only with appendicectomy. Conclusion NETs of the appendix are the commonest appendiceal neoplasms. The majority of them are diagnosed incidentally in appendicectomy specimens. Surgical management of the tumours is either by appendicectomy or hemicolectomy, which depends mainly on tumor size. Surgical decisions should be tailor-made to the patients based on multi-disciplinary team decisions.

Abstract
Emergency appendectomy (EA) is the gold standard management for acute appendicitis (AA). However, whether EA or interval appendectomy (IA) after conservative treatment is the optimal approach in AA with abscess remains controversial. This study compared IA and EA in patients presenting with AA accompanied by abscess. This was a retrospective single-center study including 446 consecutive patients undergoing appendectomy between April 2009 and March 2023. AA with abscess was defined as a pericecal abscess observed by computed tomography or abdominal ultrasonography, and patients with signs of peritoneal irritation were excluded. Perioperative outcomes were compared between the patients who directly underwent EA and those who underwent IA after conservative treatment. Among 42 patients (9.4%) with AA and abscess, 34 and 8 patients underwent IA and EA, respectively. The rates of ileocecal resection and postoperative complications were lower in the IA group than in the EA group (3% vs. 50%, P < 0.001 and 9% vs. 75%, P < 0.001, respectively). Colonoscopy before IA was performed in 16 of the 17 patients aged ≥ 40 years in the IA group, and one patient underwent ileocecal resection because of suspicious neoplasm in the root of the appendix. IA after conservative treatment might be considered as the useful therapeutic option for AA with abscess. Colonoscopy during the waiting period between the initial diagnosis and IA should be considered in patients aged ≥ 40 years who may have malignant changes. Implementing IA as a first-line treatment will be beneficial to both patients and healthcare providers.

Abstract
OBJECTIVE This study analyzes national trends in the management of uncomplicated appendicitis during pregnancy, comparing outcomes for nonoperative management (NOM) and appendectomy. BACKGROUND In the nonpregnant population, several randomized controlled trials demonstrated noninferiority of NOM compared with appendectomy for acute uncomplicated appendicitis. However, it remains unclear whether these findings are generalizable to pregnant patients. METHODS The National Inpatient Sample was queried for pregnant women diagnosed with acute uncomplicated appendicitis from January 2003 to September 2015. Patients were categorized by treatment: NOM, laparoscopic appendectomy (LA), and open appendectomy. A quasi-experimental analysis with interrupted time series examined the relationship between the year of admission and the likelihood of receiving NOM. Multivariable logistic regression analyses were used to evaluate the association between treatment strategy and patient outcomes. RESULTS A total of 33,120 women satisfied the inclusion criteria. Respectively, 1070 (3.2%), 18,736 (56.6%), and 13,314 (40.2%) underwent NOM, LA, and open appendectomy. The NOM rate significantly increased between 2006 and 2015, with an annual increase of 13.9% (95% CI, 8.5-19.4, P <0.001). Compared with LA, NOM was significantly associated with higher rates of preterm abortion (odds ratio [OR]: 3.057, 95% CI, 2.210-4.229, P <0.001) and preterm labor/delivery (OR: 3.186, 95% CI, 2.326-4.365, P <0.001). Each day of delay to appendectomy was associated with significantly greater rates of preterm abortion (OR: 1.210, 95% CI, 1.123-1.303, P <0.001). CONCLUSIONS Although NOM has been increasing as a treatment for pregnant patients with uncomplicated appendicitis, compared with LA, it is associated with worse clinical outcomes.

Abstract
INTRODUCTION Acute appendicitis (AA) is one of the most common surgical emergencies, with a lifetime risk estimated at 7-8%. Pregnant women with appendicitis can have a difficult diagnosis because many signs and symptoms could overlap with other causes of acute abdominal pain. Although magnetic resonance imaging (MRI) is not contraindicated at all gestational ages for units with a field strength of three Tesla or less, there is still much discussion regarding the best protocol to follow in order to minimize survey time and maximize diagnostic efficiency. The purpose of this study was to assess how well different MR pulse sequences can diagnose AA. METHODS This retrospective study involved 179 pregnant females. All patients treated and admitted to the University Medical Center, Ho Chi Minh City, Vietnam, between January 2016 and October 2023 had their MR scans and medical data examined. MRI results were assessed and compared with surgical and histopathological findings. RESULTS The mean age of the population was 29.7 ± 4.8 years (range, 18-46 years). On T1-weighted (T1W) and T2-weighted (T2W) sequences, the appendix was clearly visualized at rates of 81.8% and 89.9%, respectively. The sensitivity and specificity of the T2W in diagnosing AA were 93.5% and 92.3%, and when combined with T1W and diffusion-weighted (DW) images, the sensitivity and specificity further increased, being 96.8% and 94.9%, respectively. The predictive value of non-AA of the T1 bright appendix sign was 95.6%. CONCLUSION Our study supports the use of MRI as an imaging test to identify appendicitis during pregnancy, as it has been shown to be a useful method for diagnosing the condition in pregnant women. The T2W pulse sequence is a useful tool for diagnosing appendicitis because of its high sensitivity and specificity. When identifying appendicitis from T2W alone proves challenging, T1W with the T1 bright sign and DW to take advantage of the appendix lumen and/or wall's diffusion features can yield additional information and boost diagnostic confidence.

Abstract
OBJECTIVE To investigate the risk factors and the value of clinical prediction model for complicated appendicitis (CA) during pregnancy. METHODS Prospective analysis of pregnant patients who underwent appendectomy at a single tertiary care center between February 2020 and February 2023 and who ultimately had pathologically confirmed acute appendicitis (AA). According to intraoperative conditions and postoperative pathology, they were divided into the CA group and the uncomplicated appendicitis (UA) group. The two groups of patients were then compared in terms of demographic characteristics, disease features, ancillary tests and predictive models of acute appendicitis. RESULTS A total of 90 patients with AA in pregnancy were included, 21 of whom had CA in pregnancy and 69 had UA in pregnancy. Multivariate regression analysis showed that gestational week, neutrophil ratio and C-reactive protein (CRP) were independent risk factors for CA during pregnancy. Relative to the first trimester, the third trimesters had an increased risk of complicated appendicitis (OR = 12.48, 95% CI: 1.56-99.57, P = 0.017). Neutrophil ratio ≥85.30% (OR = 24.54, 95% CI: 2.59-232.72, P = 0.005) and CRP ≥34.26 mg/L (OR = 7.86, 95% CI: 2.18-28.38, P = 0.002) had a significantly increased risk of CA. The AIR and AAS score models were statistically different between the two groups, but with a lower sensitivity of 52.38% and 42.86%, respectively. CONCLUSION The third trimesters, neutrophil ratio ≥85.30% and CRP ≥34.26 mg/L may be key predictors of CA in pregnancy. The current scoring model is inadequate to identify complex appendicitis in pregnancy and further research is needed.

Abstract
BACKGROUND The optimal diagnosis and treatment of appendicitis remains controversial. This systematic review details the evidence and current best practices for the evaluation and management of uncomplicated and complicated appendicitis in adults and children. METHODS Eight questions regarding the diagnosis and management of appendicitis were formulated. PubMed, Embase, CINAHL, Cochrane and clinicaltrials.gov/NLM were queried for articles published from 2010 to 2022 with key words related to at least one question. Randomized and non-randomized studies were included. Two reviewers screened each publication for eligibility and then extracted data from eligible studies. Random effects meta-analyses were performed on all quantitative data. The quality of randomized and non-randomized studies was assessed using the Cochrane Risk of Bias 2.0 or Newcastle Ottawa Scale, respectively. RESULTS 2792 studies were screened and 261 were included. Most had a high risk of bias. Computerized tomography scan yielded the highest sensitivity (> 80%) and specificity (> 93%) in the adult population, although high variability existed. In adults with uncomplicated appendicitis, non-operative management resulted in higher odds of readmission (OR 6.10) and need for operation (OR 20.09), but less time to return to work/school (SMD - 1.78). In pediatric patients with uncomplicated appendicitis, non-operative management also resulted in higher odds of need for operation (OR 38.31). In adult patients with complicated appendicitis, there were higher odds of need for operation following antibiotic treatment only (OR 29.00), while pediatric patients had higher odds of abscess formation (OR 2.23). In pediatric patients undergoing appendectomy for complicated appendicitis, higher risk of reoperation at any time point was observed in patients who had drains placed at the time of operation (RR 2.04). CONCLUSIONS This review demonstrates the diagnosis and treatment of appendicitis remains nuanced. A personalized approach and appropriate patient selection remain key to treatment success. Further research on controversies in treatment would be useful for optimal management.

Abstract
INTRODUCTION Bacteria play an important role not only in pathogenesis of appendicitis but also in the postoperative course of patients. However, the usefulness of an intraoperative swab during appendectomy is controversial. The primary aim of this study was to investigate the impact of intraoperative swab during appendectomy on the postoperative outcome in patients with uncomplicated and complicated appendicitis. METHODS A retrospective analysis was conducted on a consecutive series of 1570 adult patients who underwent appendectomy for acute appendicitis at the University Hospital Erlangen between 2010 and 2020. Data regarding the intraoperative swab were collected and analyzed for the entire cohort as well as for patients with uncomplicated and complicated appendicitis. RESULTS An intraoperative swab was taken in 29% of the cohort. The bacterial isolation rate in the obtained intraoperative swabs was 51%, with a significantly higher rate observed in patients with complicated appendicitis compared to those with uncomplicated appendicitis (79% vs. 35%, p < 0.001). The presence of a positive swab was significantly associated with worse postoperative outcomes, including higher morbidity, increased need for re-surgery, and longer hospital stay, when compared to patients without a swab or with a negative swab. A positive swab was an independent risk factor for postoperative morbidity (OR 9.9 (95% CI 1.2-81.9), p = 0.034) and the need for adjustment of postoperative antibiotic therapy (OR 8.8 (95% CI 1.1-72.5), p = 0.043). However, a positive swab resulted in postoperative antibiotic therapy adjustment in only 8% of the patients with bacterial isolation in the swab. CONCLUSION The analysis of swab samples obtained during appendectomy for acute appendicitis can help identify patients at a higher risk of a worse postoperative outcome. However, the frequency of antibiotic regime changes based on the swab analysis is low.

Abstract
OBJECTIVE Acute appendicitis (AA) is the most common cause of acute abdomen and appendectomy is one of the most common surgical procedures. In this study, we aimed to compare open appendectomy (OA) and laparoscopic (LA) surgical techniques in the treatment of AA. METHODS The data of 236 patients treated with the diagnosis of AA in 2019-2020 were analyzed. Of these patients, 85 patients who received OA and 84 patients who received LA were included in the study. Then, the two groups were compared in terms of demographic, laboratory, clinical, and surgical treatments. RESULTS A total of 169 patients were included in the study. The mean age was 34.9 years (range 16-78), and the male-to-female ratio was 0.69. Statistical analysis revealed that the OA group had more leukocytosis, more female gender, and longer operation time than the LA group, but the LA group's complication rate was lower (p<0.05). CONCLUSION LA offers less morbidity, a shorter duration of hospital stay, and a fast return to normal activities compared to OA. In the surgical treatment of AA, LA can be applied as a routine and first-line treatment.

Abstract
The most frequent reason for individuals experiencing abdominal discomfort to be referred to emergency departments of hospitals is acute appendicitis, and the most frequent emergency surgery performed is an appendectomy. The purpose of this study was to design and develop an intelligent clinical decision support system for the timely and accurate diagnosis of acute appendicitis. The number of participants which is equal to 181 was chosen as the sample size for developing and evaluating neural networks. The information was gathered from the medical files of patients who underwent appendicectomies at Shahid Modarres Hospital as well as from the findings of their appendix samples' pathological tests. The diagnostic outcomes were then ascertained by the development and comparison of a Multilayer Perceptron network (MLP) and a Support Vector Machine (SVM) system in the MATLAB environment. The SVM algorithm functioned as the central processing unit in the Clinical Decision Support System (CDSS) that was built. The intelligent appendicitis diagnostic system was subsequently developed utilizing the Java programming language. Technical evaluation and system usability testing were both done as part of the software evaluation process. Comparing the output of the optimized artificial neural network of the SVM with the pathology result showed that the network's sensitivity, specificity, and accuracy were 91.7%, 96.2%, and 95%, respectively, in diagnosing acute appendicitis. Based on the existing standards and the opinions of general surgeons, and also comparing the results with the diagnostic accuracy of general surgeons, findings indicated the proper functioning of the network for the diagnosis of acute appendicitis. The use of this system in medical centers is useful for purposes such as timely diagnosis and prevention of negative appendectomy, reducing patient hospital stays and treatment costs, and improving the patient referral system.

Abstract
BACKGROUND Despite the human immunodeficiency virus (HIV) being the most common comorbidity in South African surgical patients, its impact on appendicitis has not been well-described. We aimed to determine HIV status' influence on patients' presentation, assessment, management and outcomes with acute appendicitis. METHODS The retrospective chart review included all patients aged 12 years and older who were HIV-positive or HIV-negative and presented with acute appendicitis between 1 January 2013 and 31 December 2019. The primary outcome measure was survival to discharge. Secondary outcomes included analysis of the presentation (vital signs), assessment (biochemical, inflammatory markers) and management (intraoperative anatomical severity grading, length of hospital stay). RESULTS Of the 1096 patients with appendicitis, 196 (17.9%) were HIV-positive, and CD4 counts were available for 159. The median age was 23 years, with the HIV-positive patients being older and HIV-negative group having more males (58.7%). While the HIV-positive patients had a longer median length of hospital stay, there was no statistically significant difference in the two groups' incidence of high-grade appendicitis (p = 0.670). The HIV-positive patients had a higher median shock index (OR 7.65; 95% [CI 2.042-28.64]) than their HIV-negative counterparts. HIV-positivity had a significant association with mortality (OR 9.56; 95% CI [1.68-179.39]), and of the seven HIV-positive patients who died, 66.7% (n = 4) had a CD4 < 200 cells/mm3 (OR 8.6; 95% CI [1.6-63.9]). CONCLUSION HIV-positive patients, those with CD4 < 200 cells/mm3 or not on ART, have increased mortality risk and may benefit from increased perioperative surveillance. Patients with an unknown HIV status in a high-prevalence population should be offered HIV testing to risk stratify more accurately.

Abstract
BACKGROUND Acute appendicitis is one of the most common surgical causes of acute abdominal pain in adults and children in the emergency department. It is treated by appendectomy by either an open or laparoscopic approach. Although laparoscopic appendectomy has been used for the last 35 years, there are still indications for an open approach in some cases. OBJECTIVES The aim of this study was to explore the awareness of the general population in Saudi Arabia of appendectomy according to the surgical approach. METHODS A cross-sectional survey using a questionnaire constructed by an expert based on Google Forms (Google, Mountain View, CA) was used from February to March 2022. Variables were demographical data, general knowledge, history of appendectomy, its surgical approach, and postoperative complications, if any. RESULTS The study included 162 participants. The awareness level of acute appendicitis was high (72.2%). History of appendectomy was almost 30% and was significantly more common in males than females (p = 0.045). The rate of postoperative complications showed a significant difference between open (4.3%) vs. laparoscopic approaches (8%) (p = 0.001). CONCLUSION Young, educated Saudis are aware of the importance of surgical intervention for acute appendicitis. However, further hospital-based studies are recommended concerning the role of the surgical approach and its various impacts on postoperative complications.

Abstract
INTRODUCTION Neuroendocrine neoplasms (NEN) are rare and heterogeneous epithelial tumors, occurring throughout the body. For gastroenteropancreatic (GEP)-NEN, rising incidence rates were reported for the last decades, with underlying causes remaining largely unexplained. We evaluated NEN trends stratifying by their histologic subtypes. METHODS Incident cases of GEP-NEN diagnosed between 2005 and 2019 were retrieved from the prospective, population-based Bavarian Cancer Registry. GEP-NEN were divided in their histologic subtypes, that is, neuroendocrine tumors (NET) G1, NET G2/G3, other NET versus small-cell neuroendocrine carcinoma (NEC), large-cell NEC, and other NEC. We calculated annual age-standardized incidence rates (ASIRs) per 100,000 persons for the total of GEP-NEN, NEN histologic subtypes, and tumor sites. We used an annual percentage change (APC) approach including a joinpoint analysis to investigate NEN incidence trends. RESULTS ASIR of GEP-NEN rose from 2.2 in 2005 to 4.8 in 2019, characterized by a significant increase until 2012 (APC 2005-2012: 10.1%), followed by modest rise (APC 2012-2019: 1.5%). In the last decade, this increase was mainly driven by the rise of NET G1 and G2/G3, while incidence for NEC declined. Over the study period, ASIR increased significantly for all GEP-sites except the colon. APCs were largest for the stomach, the appendix, the pancreas, and the rectum. CONCLUSIONS This study found a significant increase in the incidence of GEP-NET. Though this development may partially be attributable to the increased use of advanced detection techniques and changes in NEN classification, further research should also focus on the identification of NEN risk factors.

Abstract
INTRODUCTION The COVID-19 pandemic impacted presentation, management strategies, and patient outcomes of numerous medical conditions. The aim of this study is to perform a year-to-year comparison of clinical outcomes of patients with acute appendicitis (AA) before and during the pandemic. METHODS Patients treated for AA during the initial 12-mo period of the pandemic at our institute were compared to those treated for AA during the 12-mo period before. Clinical and laboratory parameters, treatment strategies, intraoperative findings, pathology reports, and postoperative outcomes were compared. RESULTS During the study period, 541 patients presented with AA. The median (interquartile range) age was 28 (21-40) y and 292 (54%) were males. 262 (48%) patients presented during the pre-COVID-19 period, while 279 patients (52%) presented during the COVID 19 pandemic. The groups were comparable for baseline clinical data and imaging results upon index admission. There was no significant difference in rate of nonoperative treatment between the Pre-COVID-19 and During-COVID-19 eras (51% versus 53%, P = 0.6) as well as the success rate of such treatment (95.4% versus 96.4%, P = 0.3). Significantly more patients presented with a periappendicular abscess during COVID-19 (4.6% versus 1.1%, P = 0.01) and median (interquartile range) operative time was significantly longer (78 (61-90) versus 32.5 (27-45) min, P < 0.001). Pathology reports revealed a higher rate of perforated appendicitis during COVID-19 (27.4% versus 10.2%, P < 0.001). CONCLUSIONS Patients with AA present with higher rates of perforated and complicated appendicitis during the COVID-19 pandemic. The success rates of nonoperative management in selected patients with noncomplicated AA did not change during the pandemic and is a safe, feasible, option.

Abstract
INTRODUCTION Laparoscopic appendectomy has been used in the treatment of appendicitis, which is among the most common emergency pathologies worldwide. There is no consensus on the best trocar entry sites. The purpose of the present study was to compare various trocar entry sites in the literature and to find the localization with the optimal usage area. METHODS Patients who underwent laparoscopic appendectomy between 2021 and 2022 were randomized into 4 groups and included in the study. The demographic data, perioperative, and postoperative findings of the patients were evaluated. RESULTS A total of 200 patients participated in the study and 73% were male. No differences were detected between the groups in terms of demographic data, preoperative findings, length of stay, and complications of the patients. However, when the mean surgery times of the groups were examined (47.2±26.9, 58.4±23.1, 54.5±18.3, 55.8±18.6 min), it was observed that this period was less in Group 1 ( P =0.02). When the postoperative Visual Analogue Scale values were analyzed (4.8±2.2, 6.2±1.7, 5.5±2.0, and 5.8±1.9), Group 1 was found to be less painful ( P =0.00001). CONCLUSION When the surgical procedure is optimized and environmental factors are homogenized, Group 1 trocar entry sites seem advantageous for the procedure in terms of postoperative patient pain scale and operation times.

Correlation between the presence of a cecal appendix and reduced diarrhea severity in primates: new insights into the presumed function of the appendix. Sci Rep 2023; 13:15897.

Abstract
Increased severity or recurrence risk of some specific infectious diarrhea, such a salmonellosis or Clostridium difficile colitis, have been reported after an appendectomy in human patients. While several other mammals also possess an appendix, the suspected protective function against diarrhea conferred by this structure is known only in humans. From a retrospective collection of veterinary records of 1251 primates attributed to 45 species, including 13 species with an appendix and 32 without, we identified 2855 episodes of diarrhea, 13% of which were classified as severe diarrhea requiring a therapeutic medication or associated with a fatal issue. We identified a lower risk of severe diarrhea among primate species with an appendix, especially in the early part of life when the risk of diarrhea is maximal. Moreover, we observed a delayed onset of diarrhea and of severe diarrhea in species possessing an appendix. Interestingly, none of the primates with an appendix were diagnosed, treated or died of an acute appendicitis during the 20 years of veterinarian follow-up. These results clarify the function of the appendix among primates, as protection against diarrhea. This supports its presumed function in humans and is congruent with the existence of a selective advantage conferred by this structure.

Int J Surg 2023; 109:2608-2613. [PMID: 37232122 PMCID: PMC10498886 DOI: 10.1097/js9.0000000000000499] [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: 03/07/2023] [Accepted: 05/10/2023] [Indexed: 05/27/2023]
Abstract
BACKGROUND Appendicitis places a substantial burden on healthcare systems, with acute appendicitis alone being the most common abdominal surgical emergency worldwide. Further characterisation of the disease burden in EU15+ countries may help optimise the distribution of healthcare resources. The aim of this observational study was to assess the trends in mortality, incidence and disability-adjusted life-years (DALYs) of appendicitis across European Union (EU) 15+ countries between the years 1990 and 2019, Supplemental Digital Content 3, http://links.lww.com/JS9/A589 . MATERIALS AND METHODS Age-standardised mortality rates (ASMRs), age-standardised incidence rates (ASIRs) and DALYs data for appendicitis in males and females were extracted from the 2019 Global Burden of Disease (GBD) study. Temporal trends within the study period were analysed using Joinpoint regression analysis. RESULTS The median ASMRs across EU15+ countries in 2019 were 0.08/100 000 and 0.13/100 000 for females and males, respectively. Between 1990 and 2019 the median percentage change in ASMR was -52.12% for females and -53.18% in males. The median ASIRs in 2019 for females and males were 251/100 000 and 278/100 000, respectively, with a median percentage change of +7.22% for females and +3.78% for males during the observation period. Decreasing trends in DALYs were observed over the 30-year study period, with median percentage changes of -23.57% and -33.81% for females and males, respectively, Supplemental Digital Content 3, http://links.lww.com/JS9/A589 . CONCLUSION Overall, a general trend of decreasing appendicitis ASMRs and DALYs was observed across EU15+ countries, despite small overall increases in appendicitis ASIRs, Supplemental Digital Content 3, http://links.lww.com/JS9/A589 . Variations in both diagnostic and management strategies over the study period are likely contributory to the changing trends.
