ABSTRACT
Introduction: Measures taken to prevent the spread of coronavirus disease 2019 (COVID-19) slow surgical processes, and patients are avoiding presenting at emergency departments during the outbreak because of fears of contracting the contagious disease. To analyze the rate of complicated appendicitis before and during the COVID-19 pandemic. Methods: We systematically reviewed the PubMed and SCOPUS databases for articles published from 2000 to 2021. Including the retrospective review data collected from our hospital of patients aged ≥18 years old who were diagnosed with acute appendicitis. The primary outcome of complicated appendicitis incidence was compared between before and during the COVID-19 pandemic period. We performed a meta-analysis using a random-effects model analysis. Results: A total 3559 patients were included for meta-analysis. The overall rate of complicated appendicitis was significantly higher during the pandemic (relative risk, 1.55; 95% confidence interval [CI], 1.26-1.89). The time from onset of symptoms to hospitalisation was 0.41 h longer during the pandemic, which was not significantly different (standardized mean difference, 0.41, 95% CI, -0.03 to 1.11). The operating time during the pandemic was significantly shorter than that before the pandemic (83.45 min and 71.65 min, p = 0.01). Conclusion: There are correlation between the pandemic and severity of acute appendicitis. The higher rate of complicated appendicitis in the pandemic indicates that patients require timely medical attention and appropriate treatment despite fears of contracting disease.
ABSTRACT
INTRODUCTION: Between 5% and 30% of abdominal incisions eventually result in incisional hernias (IHs) that can lead to severe complications and impaired quality of life. Unfortunately, IH repair is often unsuccessful; therefore, hernia prophylaxis is an important issue. The efficacy of mesh augmentation has been proven for hernia prophylaxis in high-risk patients, but no randomised clinical trial has evaluated prophylactic mesh placement in emergency/urgent gastrointestinal operations. METHODS AND ANALYSIS: A multicentre, prospective randomised, open and patient-assessor blinded endpoint design will be conducted. A total of 470 patients will be enrolled and randomly allocated to retrorectus mesh augmentation with lightweight polypropylene mesh or primary suture closure. The primary outcome is IH occurrence within 24 months of follow-up, while other clinical outcomes are secondary endpoints. A cost-effectiveness analysis will be conducted from the societal and provider perspectives. ETHICS AND DISSEMINATION: Ethics approval was obtained from Ramathibodi Hospital (MURA2020/1478) and Vajira Hospital (COA164/2563). The protocol is on the process of submission to the local ethics committee of the other study sites. Results will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: TCTR20200924002.
