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

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

Abstract
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.

[PMID: 37790034 PMCID: PMC10544542 DOI: 10.7759/cureus.44506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/31/2023] [Indexed: 10/05/2023] Open
Abstract
Prior to the development of laparoscopic procedures, open appendectomy was the standard of care for the majority of appendicitis cases. Recently, studies have debated using antibiotics as a first-line treatment in uncomplicated appendicitis cases. The definition of uncomplicated appendicitis is not always clear-cut; however, with the large-scale accessibility of radiologic techniques, it is becoming increasingly easier to classify patient groups. As suggested by clinical and radiological patient data, this has raised the speculation of considering antibiotic therapy as the sole treatment modality in uncomplicated appendicitis cases. We aim to compare the options of surgery and antibiotics only in terms of efficacy, complications, and financial cost. A range of databases and search strategies were adopted, and various databases were used, including PubMed, ScienceDirect, Google Scholar, and JAMA. Collectively, 30 studies were reviewed, but only 18 were included. Efficacy rates were higher in the appendectomy group. Nevertheless, the antibiotics-only group maintained an efficacy rate greater than 70% at one-year follow-up. Risk factors that decreased the efficacy in medical management included the presence of appendicolith, neoplasm, appendiceal dilatation, peri-appendiceal fluid collection, higher mean temperature, CRP, and bilirubin. Complications were more frequent and significant in the surgery group. These included complications related to anaesthesia, surgical site infections, damage to nearby structures, and pulmonary embolism. Despite several years of follow-up and disease recurrences, higher financial costs were observed in surgically treated patients compared to the antibiotics-only group. Given the high success rates post-appendectomy for acute appendicitis over the decades, the efficacy of conservatively treated acute appendicitis raises a strong argument when choosing one of the two options. The efficacy remained consistently higher across the literature in the surgery group than in the antibiotics-only group. However, it is still arguable that antibiotics may be a preferable option given an efficacy rate of more than 70% at one year and overall higher complications associated with surgery. The argument of missing a neoplasm by avoiding surgery is valid. However, most are carcinoid neuroendocrine neoplasms with a low probability of metastasis (<5%) and are usually considered benign. Given the current practice focused on conservative and minimally invasive treatments and recently the COVID-19 pandemic, with its restrictions and lessons learnt, antibiotics may be the future standard for treating uncomplicated acute appendicitis. Lastly, we noticed higher efficacy rates in articles published recently than those published at least five to ten years earlier. Antibiotics-only therapy for uncomplicated appendicitis is cost-effective with fewer complications than surgery. However, appendectomies have higher efficacy. Thus, surgical treatment prevails as the standard of care. Future literature should yield larger sample sizes and explore the numbers of emergency appendectomies mandated following antibiotics-only therapy.

Abstract
OBJECTIVE This meta-analysis aimed to compare the efficacy and safety of antibiotic treatment and appendectomy for acute uncomplicated appendicitis. METHODS We searched the randomized controlled studies (RCTs) comparing appendectomy with antibiotic treatment for uncomplicated acute appendicitis in the electronic database including Pubmed, Embase, Cochrane, Web of Science, CNKI, VIP, and WanFang. The primary outcomes included complication-free treatment success at 1 year, complications, surgical complications, and the complicated appendicitis rates. Secondary outcomes included negative appendicitis, length of hospital stay, the quality of life at 1 month, and the impact of an appendicolith on antibiotic therapy. RESULTS Twelve randomized controlled studies were included. Compared with surgery group, the antibiotic group decreased the complication-free treatment success at 1 year (RR 0.81; 95% CI 0.73-0.91; z = 3.65; p = 0.000). Statistically significance was existed between antibiotic group and surgical group with both surgical types(open and laparoscopic) (RR 0.43; 95% CI 0.31-0.58; z = 5.36; p = 0.000), while no between the antibiotic treatment and laparoscopic surgery (RR 0.72; 95% CI 0.41-1.24; z = 1.19; p = 0.236). There was no statistically significant differences between two groups of surgical complications (RR 1.38; 95% CI 0.70-2.73; z = 0.93; p = 0.353), the complicated appendicitis rate (RR 0.71; 95% CI 0.36-1.42; z = 0.96; p = 0.338), negative appendectomy rate (RR 1.11; 95% CI 0.69-1.79; z = 0.43; p = 0.670), duration of hospital stay (SMD 0.08; 95%CI -0.11-0.27; z = 0.80; p = 0.422), and quality of life at 1 month (SMD 0.09; 95%CI -0.03-0.20; z = 1.53; p = 0.127). However, in the antibiotic treatment group, appendicolith rates were statistically higher in those whose symptoms did not improve (RR 2.94; 95% CI 1.28-6.74; z = 2.55; p = 0.011). CONCLUSIONS Although the cure rate of antibiotics is lower than surgery, antibiotic treatment is still a reasonable option for patients with uncomplicated acute appendicitis who do not want surgery without having to worry about complications or complicating the original illness.

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

Abstract
INTRODUCTION Imaging-confirmed uncomplicated acute appendicitis can be effectively and safely treated with antibiotics in most adults and children. Symptomatic treatment may have similar efficacy and safety. METHODS AND ANALYSIS The APPSYPP trial is a randomized national multicenter feasibility superiority pilot study comparing appendectomy with symptomatic treatment in children with imaging-confirmed uncomplicated acute appendicitis. INCLUSION CRITERIA 1) age ≥ 7 and < 16 years, 2) imaging-confirmed uncomplicated acute appendicitis and 3) CRP ≤ 65 mg/l. Patients are randomized to receive emergency laparoscopic appendectomy or symptomatic treatment. To ensure patient safety, symptomatically treated patients are hospitalized for at least 24 h receiving standard practice intravenous fluids and analgesics according to standard clinical practice. Primary outcome is 30-day treatment success defined by the absence of any treatment failure criteria. In appendectomy, treatment failure is defined as normal appendiceal histopathology or any postintervention complication requiring general anesthesia. In symptomatic treatment, treatment failure is defined as 1) inability for hospital discharge without appendectomy within 48 h after randomization with a finding of histopathologically inflamed appendix, 2) appendectomy during the initial hospital stay due to clinical progression of appendicitis with complicated acute appendicitis both histopathologically and surgically, 3) appendectomy with a histopathological finding of acute appendicitis after hospital discharge, or 4) any complication of appendicitis requiring general anesthesia. Detailed predefined secondary outcomes will be analyzed. ETHICS AND DISSEMINATION Study was approved by Ethics Committee of Helsinki University Hospital (ID:HUS/1993/2021), conducted in compliance with the declaration of Helsinki with results disseminated in peer-reviewed scientific journals. TRIAL REGISTRATION ClinicalTrials.gov (NCT05289713). STRENGTHS AND LIMITATIONS OF THIS STUDY

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

Herrod PJJ, Kwok AT, Lobo DN. Randomized clinical trials comparing antibiotic therapy with appendicectomy for uncomplicated acute appendicitis: meta-analysis. BJS Open 2022; 6:6667669. [PMID: 35971796 PMCID: PMC9379374 DOI: 10.1093/bjsopen/zrac100] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 07/01/2022] [Accepted: 07/08/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND This aim of this study was to provide an updated meta-analysis comparing antibiotic therapy with appendicectomy in adults (16 years or older) with uncomplicated acute appendicitis. METHODS A search for randomized clinical trials comparing antibiotic therapy with appendicectomy in adults with uncomplicated acute appendicitis from inception to 3 October 2021 in MEDLINE, Embase and CENTRAL with no language constraints was performed. Studies were excluded if they included paediatric participants or those with complicated appendicitis. Data on complications of treatment, treatment efficacy (defined in the antibiotic group as not undergoing appendicectomy within 1 year of enrolment, versus surgery without complications or no negative histology in the appendicectomy group), readmissions, and length of stay (LOS) were presented. RESULTS Eight RCTs involving 3203 participants (1613 antibiotics/1590 appendicectomy; 2041 males/1162 females) were included. There was no significant benefit of antibiotic treatment on complication rates (risk ratio (RR) 0.66, 95 per cent c.i. 0.41 to 1.04). Antibiotics had a reduced treatment efficacy compared with appendicectomy (RR 0.75, 95 per cent c.i. 0.63 to 0.89). Antibiotic treatment at 1 year was successful in 1016 of 1613 (62.9 per cent) participants. There was a six-fold increase in hospital readmissions within 1 year of enrolment in participants receiving antibiotic treatment (RR 6.28, 95 per cent c.i. 2.87 to 13.74). There was no difference in index admission LOS (mean difference 0.15 days (95 per cent c.i. -0.05 to 0.35)). CONCLUSIONS Earlier optimism regarding the benefits of antibiotic therapy for uncomplicated acute appendicitis does not persist at the same level now that further, large trials have been included. If antibiotic treatment is to be offered routinely as first-line therapy, patients should be counselled appropriately.

Abstract
Background: Mean Platelet Volume (MPV) has been suggested as a biomarker for acute appendicitis (AA) in the adult population. The utility of MPV in pediatric AA remains vague. This systematic review and meta-analysis aimed to systematically summarize and compare all relevant data on MPV as a diagnostic biomarker for AA in children. Methods: Databases were systematically searched using keywords ((mean platelet volume) OR mpv) AND (appendicitis). The inclusion criteria were all comparative studies of MPV in children aged less than 18 years and diagnosed with AA. Two authors independently assessed the methodological quality using the Downs and Black scale. Results: We included fourteen studies in the final meta-analysis; most were retrospective. Eight studies compared the MPV values between AA and non-AA; four studies compared the same between AA and healthy controls; two studies compared the MPV values among all three groups. The estimated heterogeneity among the studies for all outcomes was high and statistically significant. The pooling the data showed no statistically significant difference in MPV (weighted mean difference (WMD) = −0.42, 95% CI = (−1.04, 0.20), p = 0.19) between AA and healthy controls or AA and non-AA cases (WMD = 0.01, 95% CI = (−0.15, 0.17), p = 0.90). Conclusion: While MPV levels seem to have some utility in adult AA diagnosis, MPV levels should not dictate treatment options in pediatric AA.

Abstract
BACKGROUND The incidence of spinal epidural abscesses is increasing. What is more, they are associated with high rates of morbidity and mortality. Advances in diagnostic imaging and antibiotic therapies have made earlier diagnosis and nonoperative management feasible in appropriately selected patients. Nonoperative treatment also has the advantage of lower immediate healthcare charges; however, it is unknown whether initial nonoperative care leads to higher healthcare charges long term. QUESTIONS/PURPOSES (1) Does operative intervention generate higher charges than nonoperative treatment over the course of 1 year after the initial treatment of spinal epidural abscesses? (2) Does the treatment of spinal epidural abscesses in people who actively use intravenous drugs generate higher charges than management in people who do not? METHODS This retrospective comparative study at two tertiary academic centers compared adult patients with spinal epidural abscesses treated operatively and nonoperatively from January 2016 through December 2017. Ninety-five patients were identified, with four excluded for lack of billing data and one excluded for concomitant intracranial abscess. Indications for operative management included new or progressive motor deficit, lack of response to nonoperative treatment including persistent or progressive systemic illness, or initial sepsis requiring urgent source control. Of the included patients, 52% (47 of 90) received operative treatment with no differences in age, gender, BMI, and Charlson comorbidity index between groups, nor any difference in 30-day all-cause readmission rate, 1-year reoperation rate, or 2-year mortality. Furthermore, 29% (26 of 90) of patients actively used intravenous drugs and were younger, with a lower BMI and lower Charlson comorbidity index, with no differences in 30-day all-cause readmission rate, 1-year reoperation rate, or 2-year mortality. Cumulative charges at the index hospital discharge and 90 days and 1 year after discharge were compared based on operative or nonoperative management and secondarily by intravenous drug use status. Medical records, laboratory results, and hospital billing data were reviewed for data extraction. Demographic factors including age, gender, region of abscess, intravenous drug use, and comorbidities were extracted, along with clinical factors such as symptoms and ambulatory function at presentation, spinal instability, intensive care unit admission, and complications. The primary outcome was charges associated with care at the index hospital discharge and 90 days and 1 year after discharge. All covariates extracted were included in this analysis using negative binomial regression that accounted for confounders and the nonparametric nature of charge data. Results are presented as an incidence rate ratio with 95% confidence intervals. RESULTS After adjusting for demographic and clinical variables such as age, gender, BMI, ambulatory status, presence of mechanical instability, and intensive care unit admission among others, we found higher charges for the group treated with surgery compared with those treated nonoperatively at the index admission (incidence rate ratio [IRR] 1.62 [95% CI 1.35 to 1.94]; p < 0.001) and at 1 year (IRR 1.36 [95% CI 1.10 to 1.68]; p = 0.004). Adjusted analysis also showed that active intravenous drug use was also associated with higher charges at the index admission (IRR 1.57 [95% CI 1.16 to 2.14]; p = 0.004) but no difference at 1 year (IRR 1.11 [95% CI 0.79 to 1.57]; p = 0.55). CONCLUSION Multidisciplinary teams caring for patients with spinal epidural abscesses should understand that the decreased charges associated with selecting nonoperative management during the index admission persist at 1 year with no difference in 30-day readmission rates, 1-year reoperation rates, or 2-year mortality. On the other hand, patients with active intravenous drug use have higher index admission charges that do not persist at 1 year, with no difference in 30-day readmission rates, 1-year reoperation rates, or 2-year mortality. These results suggest possible economic benefit to nonoperative management of epidural abscesses without increases in readmission or mortality rates, further tipping the scale in an evolving framework of clinical decision-making. Future studies should investigate if these economic implications are mirrored on the patient-facing side to determine whether any financial burden is shifted onto patients and their families in nonoperative management. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Nonoperative management (NOM) of acute appendicitis is becoming more popular, especially in resource-strapped locations, to minimize hospital system costs. In uncomplicated cases of appendicitis, NOM can effectively treat the patient. It does carry a 39.1% risk of recurrence in 5 years, and operative management (OM) does not increase morbidity or risk of complication, so the authors recommend laparoscopic OM for uncomplicated appendicitis. For complicated cases of appendicitis, the authors recommend initial NOM with interval appendectomy in all patients. All appendicitis patients should undergo surveillance endoscopy if older than 40 years to rule out a contributing neoplasm.

Diagnostic accuracy using low-dose versus standard radiation dose CT in suspected acute appendicitis: prospective cohort study. Br J Surg 2021; 108:1483-1490.

Abstract
BACKGROUND Contrast-enhanced CT is the reference standard used in diagnostic imaging for acute appendicitis in adults. The radiation dose has been of concern. This study aimed to assess whether a lower radiation dose would affect the diagnostic accuracy of CT. METHODS This was a prospective single-centre cohort study of patients (aged over 16 years) with suspected appendicitis evaluated for enrolment in concurrent APPAC II-III trials. The diagnostic accuracy of contrast-enhanced low- and standard-dose CT was compared with study protocols guiding imaging based on BMI; this enabled direct CT imaging comparison only in patients with a BMI below 30 kg/m2. The on-call CT diagnosis was compared with the final clinical diagnosis. RESULTS Among all 856 patients investigated, the accuracy of low-dose (454 patients) and standard-dose (402 patients) CT in identifying patients with and without appendicitis was 98·0 and 98·5 per cent respectively. In patients with a BMI under 30 kg/m2, respective values were 98·2 per cent (434 patients) and 98·6 per cent (210 patients) (P = 1·000). The corresponding accuracy for differentiating between uncomplicated and complicated acute appendicitis was 90·3 and 87·6 per cent in all patients, and 89·8 and 88·4 per cent respectively among those with a BMI below 30 kg/m2 (P = 0·663). The median radiation dose in the whole low- and standard-dose CT groups was 3 and 7 mSv respectively. In the group with BMI below 30 kg/m2, corresponding median doses were 3 and 5 mSv (P < 0·001). CONCLUSION Low- and standard-dose CT were accurate both in identifying appendicitis and in differentiating between uncomplicated and complicated acute appendicitis. Low-dose CT was associated with a significant radiation dose reduction, suggesting that it should be standard clinical practice at least in patients with a BMI below 30 kg/m2.

Abstract
COVID-19 has led to profound changes in the world as we have known it. Due to the sharp increase in intensive care, COVID patients, elective admissions and interventions have been postponed. But emergencies such as myocardial infarction have also decreased. The present study deals with the effects of the COVID pandemic on visceral surgical emergencies on the basis of 5 indicator operations. Routine data from 73 acute hospitals of the Helios Group were evaluated for this purpose. The interventions that were carried out between March 13, 2020 and March 12, 2021 were included. The data was compared with the period from March 13, 2019 to March 12, 2020. The number of interventions in serious emergencies (ileus, mesenteric ischemia and ulcer perforation) has remained constant. However, the length of stay in hospital in the pandemic year 2020 was significantly shorter than in the reference year 2019. The number of cholecystectomies and appendectomies in the pandemic year was significantly lower than in the reference year 2019. The outcome parameters intensive care, invasive ventilation and hospital mortality were comparable for the two periods for these interventions.

Cost-Utility Analysis of Antibiotic Therapy versus Appendicectomy for Acute Uncomplicated Appendicitis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168473. [PMID: 34444222 PMCID: PMC8392297 DOI: 10.3390/ijerph18168473] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 08/03/2021] [Accepted: 08/06/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Current UK National Health Service (NHS) guidelines recommend appendicectomy as gold standard treatment for acute uncomplicated appendicitis. However, an alternative non-surgical management involves administrating antibiotic-only therapy with significantly lower costs. Therefore, a UK-based cost-utility analysis (CUA) was performed to compare appendicectomy with an antibiotic-only treatment from an NHS perspective. METHODS This economic evaluation modelled health-outcome data using the ACTUAA (2021) prospective multicentre trial. The non-randomised control trial followed 318 patients given either antibiotic therapy or appendicectomy, with quality of life (QOL) assessed using the SF-12 questionnaires administered 1-year post-treatment. A CUA was conducted over a 1-year time horizon, measuring benefits in quality adjusted life years (QALYs) and costs in pound sterling using a propensity score-matched approach to control for selection based on observable factors. RESULTS The CUA produced an incremental cost-effectiveness ratio (ICER) of -GBP 23,278.51 (-EUR 27,227.80) per QALY. Therefore, for each QALY gained using antibiotic-only treatment instead of appendicectomy, an extra GBP 23,278.51 was saved. Additionally, two sensitivity analyses were conducted to account for post-operative or post-treatment complications. The antibiotic-only option remained dominant in both scenarios. CONCLUSION While the results do not rely on a randomized sample, the analysis based on a 1-year follow-up suggested that antibiotics were largely more cost-effective than appendicectomy and led to improved QOL outcomes for patients. The ICER value of -GBP 23,278.51 demonstrates that the NHS must give further consideration to the current gold standard treatment in acute uncomplicated appendicitis.

Abstract
OBJECTIVE Evaluate the efficacy and quality of life associated with conservative treatment of acute uncomplicated appendicitis. SUMMARY BACKGROUND DATA Conservative management with antibiotics only has emerged as a potential treatment option for acute uncomplicated appendicitis. However the reported failure rates are highly variable and there is a paucity of data in relation to quality of life. METHODS Symptomatic patients with radiological evidence of acute, uncomplicated appendicitis were randomized to either intravenous antibiotics only or undergo appendectomy. RESULTS One hundred eighty-six patients underwent randomization. In the antibiotic-only group, 23 patients (25.3%) experienced a recurrence within 1 year following randomization. There was a significantly better EQ-VAS quality of life score in the surgery group compared with the antibiotic-only group at 3 months (94.3 vs 91.0, P < 0.001) and 12 months postintervention (94.5 vs 90.4, P < 0.001). The EQ-5D-3L quality-of-life score was significantly higher in the surgery group indicating a better quality of life (0.976 vs 0.888, P < 0.001). The accumulated 12-month sickness days was 3.6 days shorter for the antibiotics only group (5.3 vs 8.9 days; P < 0.01). The mean length of stay in both groups was not significantly different (2.3 vs 2.8 days, P = 0.13). The mean total cost in the surgery group was significantly higher than antibiotics only group (€4,816 vs €3,077, P < 0.001). CONCLUSIONS Patients with acute, uncomplicated appendicitis treated with antibiotics only experience high recurrence rates and an inferior quality of life. Surgery should remain the mainstay of treatment for this commonly encountered acute surgical condition.

Abstract
BACKGROUND There is a lack of trustworthy evidence-informed guidelines on the diagnosis and management of acute appendicitis in elderly patients. METHODS We developed a rapid guideline in accordance with GRADE and AGREE II standards. The steering group consisted of general surgeons, members of the EAES Research Committee/Guidelines Subcommittee with expertise and experience in guideline development, advanced medical statistics and evidence synthesis, biostatisticians, and a guideline methodologist. The guideline panel consisted of three general surgeons, an intensive care physician, a geriatrician and a patient advocate. We conducted systematic reviews and the results of evidence synthesis were summarized in evidence tables. Recommendations were authored and published through an online authoring and publication platform (MAGICapp), with the guideline panel making use of an evidence-to-decision framework and a Delphi process to arrive at consensus. RESULTS This rapid guideline provides a weak recommendation against the use of clinical scoring systems to replace cross-sectional imaging in the diagnostic approach of suspected appendicitis in elderly patients. It provides a weak recommendation against the use of antibiotics alone over surgical treatment in patients who are deemed fit for surgery, and a weak recommendation for laparoscopic over open surgery. Furthermore, it provides a summary of surgery-associated risks in elderly patients. The guidelines, with recommendations, evidence summaries and decision aids in user-friendly formats can also be accessed in MAGICapp: https://app.magicapp.org/#/guideline/4494 . CONCLUSIONS This rapid guideline provides evidence-informed trustworthy recommendations on the diagnosis and management of acute appendicitis in elderly patients.

The decrease of non-complicated acute appendicitis and the negative appendectomy rate during pandemic. Eur J Trauma Emerg Surg 2021; 47:1359-1365. [PMID: 33844036 PMCID: PMC8040760 DOI: 10.1007/s00068-021-01663-7] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 03/30/2021] [Indexed: 12/15/2022]
Abstract
Background During pandemic, admissions for surgical emergencies dropped down dramatically. Also acute appendicitis decreased. The aim of the present study was to evaluate the change in volume and clinical presentation of patients with acute appendicitis during pandemic and the variation in treatment. Methods This is a retrospective study of patients admitted in 11 Italian hospital for acute appendicitis during the lockdown period (March–April 2020) compared with the same period of the previous 2 years (2018–2019). The number and the rate of complicated and non-complicated acute appendicitis were recorded and compared between the two study periods; non-operative vs operative treatment and negative appendectomy rate were also recorded. Results The study included 532 patients, 112 in the study period and 420 in the control period; Hospital admission for acute appendicitis dropped by 46% (OR 0.516 95% CI 0.411–0.648 p < 0.001) during the 2020 lockdown. The number of complicated acute appendicitis did not change (− 18%, OR 0.763 95% CI 0.517–1.124 p = 0.1719), whereas the number of non-complicated acute appendicitis significantly decreased (− 56%, OR 0.424 95% CI 0.319–0.564 p < 0.001). Non-operative treatment rate remained similar (12.1% vs. 11.6% p = 0.434). The negative appendectomy rate also significantly decreased (6.1% vs. 17.3%, p = 0.006). Conclusions The present study found a significant reduction of both admissions for non-complicated acute appendicitis and negative appendectomy rate during the pandemic period. Conversely, admissions for complicated acute appendicitis did not change. Trial registration: NCT04649996.

Abstract
IMPORTANCE Antibiotics are an effective and safe alternative to appendectomy for managing uncomplicated acute appendicitis, but the optimal antibiotic regimen is not known. OBJECTIVE To compare oral antibiotics with combined intravenous followed by oral antibiotics in the management of computed tomography-confirmed uncomplicated acute appendicitis. DESIGN, SETTING, AND PARTICIPANTS The Appendicitis Acuta (APPAC) II multicenter, open-label, noninferiority randomized clinical trial was conducted from April 2017 until November 2018 in 9 Finnish hospitals. A total of 599 patients aged 18 to 60 years with computed tomography-confirmed uncomplicated acute appendicitis were enrolled in the trial. The last date of follow-up was November 29, 2019. INTERVENTIONS Patients randomized to receive oral monotherapy (n = 295) received oral moxifloxacin (400 mg/d) for 7 days. Patients randomized to receive intravenous antibiotics followed by oral antibiotics (n = 288) received intravenous ertapenem (1 g/d) for 2 days followed by oral levofloxacin (500 mg/d) and metronidazole (500 mg 3 times/d) for 5 days. MAIN OUTCOMES AND MEASURES The primary end point was treatment success (≥65%) for both groups, defined as discharge from hospital without surgery and no recurrent appendicitis during 1-year follow-up, and to determine whether oral antibiotics alone were noninferior to intravenous and oral antibiotics, with a margin of 6% for difference. RESULTS Among 599 patients who were randomized (mean [SD] age, 36 [12] years; 263 [44%] women), 581 (99.7%) were available for the 1-year follow-up. The treatment success rate at 1 year was 70.2% (1-sided 95% CI, 65.8% to ∞) for patients treated with oral antibiotics and 73.8% (1-sided 95% CI, 69.5% to ∞) for patients treated with intravenous followed by oral antibiotics. The difference was -3.6% ([1-sided 95% CI, -9.7% to ∞]; P = .26 for noninferiority), with the confidence limit exceeding the noninferiority margin. CONCLUSION AND RELEVANCE Among adults with uncomplicated acute appendicitis, treatment with 7 days of oral moxifloxacin compared with 2 days of intravenous ertapenem followed by 5 days of levofloxacin and metronidazole resulted in treatment success rates greater than 65% in both groups, but failed to demonstrate noninferiority for treatment success of oral antibiotics compared with intravenous followed by oral antibiotics.

Abstract
Objective: There is a lack of assessment methods of acute appendicitis in little children. The purpose of this study was to develop and internally validate a nomogram for predicting the severity of acute appendicitis of young children (<3 years old). Methods: We develop a prediction model based on a training dataset of 121 patients (<3 years old) with acute appendicitis. Admission information was collected between January 2010 and January 2021, which contained demographic characteristic, laboratory examinations, treatment and pathology type, etc. Logistic regression analysis was used to identify independent risk factors and establish the predictive model. C-index and calibration curves were applied to evaluate the performance of the nomogram. Then corrected C-index was calculated to conduct internal verification by using the bootstrapping validation. Decision curve analysis determined clinical application of the prediction model. Results: Predictors contained in the prediction nomogram included weight for age, onset time (from developing symptoms to hospital), admission temperature, leukocyte count, neutrophil ratio, and total bilirubin. Logistic regression analysis showed that weight for age (X1) < -2.32 SD (P = 0.046), onset time (X2) > 2.5 days (P = 0.044), admission temperature (X3) > 38.5°C (P = 0.009), leukocyte count (X4) > 12.185*109/L (P = 0.045), neutrophil ratio (X5) > 68.7% (P = 0.029), and total bilirubin (X6) > 9.05 μmol/L (P = 0.035) were found to be significant for predicting the severity of appendicitis. The logistic regression equation was logit (P) = -0.149X1 + 0.51X2 + 1.734X3 + 0.238X4 + 0.061X5 + 0.098X6 - 75.229. C-index of nomogram was calculated at 0.8948 (95% Cl: 0.8332-0.9567) and it still was 0.8867 through bootstrapping validation. Decision curve analysis showed that when the threshold probability ranged from 14 to 88%, there is a net benefit of using this prediction model for severity of appendicitis in little children. Conclusion: This novel nomogram incorporating the weight for age, onset time, admission temperature, leukocyte count, neutrophil ratio, and total bilirubin could be conveniently used to estimate the severity of appendicitis of young children <3 years old) and determine appropriate treatment options in time.

Abstract
BACKGROUND Appendicitis has traditionally been treated surgically. Recently, nonoperative management is emerging as a viable alternative to the traditional operative approach. This raises the question of what are the unintended consequences of nonoperative management of appendicitis with respect to cost and patient burden. METHODS National Readmissions Database was queried between 2010 and 2014. Patients who were admitted with acute appendicitis between January and June of each year were identified. Patients who underwent appendectomy were compared with those treated nonoperatively. Six-month all-cause readmission rates and aggregate costs between index hospitalization and readmissions were calculated. RESULTS We identified 438,995 adult admissions for acute appendicitis. Most cases were managed with appendectomy (93.2%). There was a significant increase in the rate of nonoperative management, from 3.6% in 2010 to 6.8% in 2014 (P value for trend <0.01). Discharges receiving nonoperative management tended to be older and have more comorbidities. There was a 59% decreased adjusted odds of readmission within 6 mo among patients receiving appendectomy in comparison to those managed nonoperatively. Despite this, in multivariable linear regression, there was an adjusted $2900 cost increase associated with surgical management (P < 0.01). CONCLUSIONS This study shows that nonoperative management is increasing. Patients treated nonoperatively may have an increased risk of readmission within 6 mo but incur a decreased average adjusted total cost. Given this, it is important that surgeons critically assess patients who are being considered for nonoperative management of appendicitis.

Immediate effects of urgent reorganisation of emergency department-based treatment pathway in nonperforated appendicitis: a retrospective study. BMC Emerg Med 2020; 20:45. [PMID: 32471363 PMCID: PMC7257164 DOI: 10.1186/s12873-020-00339-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Accepted: 05/20/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Acute appendicitis is a global disease and a very common indication for emergency surgery worldwide. The need for hospital resources is therefore constantly high. The administration in Kanta-Häme Central Hospital, Southern Finland, called for an urgent reorganisation due to shortage of hospital beds at the department of general surgery. Postoperative treatment pathway of patients with nonperforated acute appendicitis was ordered to take place in the Emergency Department (ED). The aim of this study was to assess, whether this reorganisation was feasible and safe, i.e. did it affect the length of in-hospital stay (LOS) and the 30-day complication rate. METHODS This is a retrospective pre- and post-intervention analysis. After the reorganisation, most patients with nonperforated appendicitis were followed postoperatively at the 24-h observation unit of the ED instead of surgical ward. Patients operated during the first 3 months after the reorganisation were compared to those operated during the 3 months before it. A case met inclusion criteria if there were no signs of appendiceal perforation during surgery. Exclusion criteria comprised age < 18 years and perforated disease. RESULTS Appendicectomy was performed on 112 patients, of whom 62 were adults with nonperforated appendicitis. Twenty-seven of the included patients were treated before the reorganisation, and 35 after it. Twenty of the latter were followed only at the ED. Postoperative LOS decreased significantly after the reorganisation. Median postoperative time till discharge was 15.7 h for all patients after the reorganisation compared to 24.4 h before the reorganisation (standard error 6.2 h, 95% confidence interval 2.3-15.2 h, p < 0.01). There were no more complications in the group treated postoperatively in the ED. CONCLUSIONS Early discharge of patients with nonperforated appendicitis after enforced urgent reorganisation of the treatment pathway in the ED observation unit is safe and feasible. Shifting the postoperative monitoring and the discharge policy of such patients to the ED - instead of the surgical ward - occurred in the majority of the cases after the reorganisation. This change may spare resources as in our series it resulted in a significantly shorter LOS without any increase in the 30-day complication rate.
