Abstract
BACKGROUND Perforated appendicitis is associated with postoperative development of intraperitoneal abscess. Intraperitoneal drain placement during appendectomy is thought to reduce the risk of developing postoperative intraperitoneal abscess. The aim of this study was to determine whether intraperitoneal drainage could reduce the incidence of intraperitoneal abscess formation after laparoscopic appendectomy for perforated appendicitis. METHODS This is a retrospective study of all patients (aged 7 and above) who were diagnosed with perforated appendicitis and subsequently underwent laparoscopic appendectomy between January 2018 and December 2022 at two government hospitals in the state of Kuwait. Demographic, clinical, and perioperative characteristics were compared between patients who underwent intraoperative intraperitoneal drain placement and those who did not. The primary outcome was the development of postoperative intraperitoneal abscess. Secondary outcomes included overall postoperative complications, superficial surgical site infection (SSI), length of stay (LOS), readmission and postoperative percutaneous drainage. RESULTS A total of 511 patients met the inclusion criteria between 2018 and 2022. Of these, 307 (60.1%) underwent intraoperative intraperitoneal drain placement. Patients with and without drains were similar regarding age, sex, and Charlson Comorbidity Index (CCI) (Table 1). The overall rate of postoperative intraperitoneal abscess was 6.1%. Postoperatively, there was no difference in postoperative intraperitoneal abscess formation between patients who underwent intraperitoneal drain placement and those who did not (6.5% vs. 5.4%, p = 0.707). Patients with intraperitoneal drains had a longer LOS (4 [4, 6] vs. 3 [2, 5] days, p < 0.001). There was no difference in the overall complication (18.6% vs. 12.3%, p = 0.065), superficial SSI (2.9% vs. 2.5%, p = 0.791) or readmission rate (4.9% vs. 4.4%, p = 0.835). CONCLUSIONS Following laparoscopic appendectomy for perforated appendicitis, intraperitoneal drain placement appears to confer no additional benefit and may prolong hospital stay.

Antibiotic treatment after appendectomy for acute complicated appendicitis to prevent intrabdominal abscess and wound infections. Langenbecks Arch Surg 2024; 409:180.

Abstract
INTRODUCTION The purpose of this analysis was to investigate the most appropriate duration of postoperative antibiotic treatment to minimize the incidence of intraabdominal abscesses and wound infections in patients with complicated appendicitis. MATERIALS AND METHODS In this retrospective study, which included 396 adult patients who underwent appendectomy for complicated appendicitis between January 2010 and December 2020 at the University Hospital Erlangen, patients were classified into two groups based on the duration of their postoperative antibiotic intake: ≤ 3 postoperative days (group 1) vs. ≥ 4 postoperative days (group 2). The incidence of postoperative intraabdominal abscesses and wound infections were compared between the groups. Additionally, multivariate risk factor analysis for the occurrence of intraabdominal abscesses and wound infections was performed. RESULTS The two groups contained 226 and 170 patients, respectively. The incidence of postoperative intraabdominal abscesses (2% vs. 3%, p = 0.507) and wound infections (3% vs. 6%, p = 0.080) did not differ significantly between the groups. Multivariate analysis revealed that an additional cecum resection (OR 5.5 (95% CI 1.4-21.5), p = 0.014) was an independent risk factor for intraabdominal abscesses. A higher BMI (OR 5.9 (95% CI 1.2-29.2), p = 0.030) and conversion to an open procedure (OR 5.2 (95% CI 1.4-20.0), p = 0.016) were identified as independent risk factors for wound infections. CONCLUSION The duration of postoperative antibiotic therapy does not appear to influence the incidence of postoperative intraabdominal abscesses and wound infections. Therefore, short-term postoperative antibiotic treatment should be preferred.

Abstract
BACKGROUND Appendicitis is an extremely common disease with a variety of medical and surgical treatment approaches. A multidisciplinary expert panel was convened to develop evidence-based recommendations to support clinicians and patients in decisions regarding the diagnosis and treatment of appendicitis. METHODS A systematic review was conducted from 2010 to 2022 to answer 8 key questions relating to the diagnosis of appendicitis, operative or nonoperative management, and specific technical and post-operative issues for appendectomy. The results of this systematic review were then presented to a panel of adult and pediatric surgeons. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. RESULTS Conditional recommendations were made in favor of uncomplicated and complicated appendicitis being managed operatively, either delayed (>12h) or immediate operation (<12h), either suction and lavage or suction alone, no routine drain placement, treatment with short-term antibiotics postoperatively for complicated appendicitis, and complicated appendicitis previously treated nonoperatively undergoing interval appendectomy. A conditional recommendation signals that the benefits of adhering to a recommendation probably outweigh the harms although it does also indicate uncertainty. CONCLUSIONS These recommendations should provide guidance with regard to current controversies in appendicitis. The panel also highlighted future research opportunities where the evidence base can be strengthened.

Abstract
BACKGROUND The burden of emergency general surgery (EGS) is higher compared to elective surgery. Acute appendicitis (AA) is one of the most frequent diseases and its management is dictated by published international clinical practice guidelines (CPG). Adherence to CPG has been reported as heterogeneous. Barriers to clinical implementation were not studied. This study explored barriers to adherence to CPG and the clinico-economic impact of poor compliance. METHODS Data were extracted from the three-year data lock of the REsiDENT-1 registry, a prospective resident-led multicenter trial. We identified 7 items from CPG published from the European Association of Endoscopic Surgery (EAES) and the World Society of Emergency Surgery (WSES). We applied our classification proposal and used a five-point Likert scale (Ls) to assess laparoscopic appendectomy (LA) difficulty. Descriptive analyses were performed to explore compliance and group comparisons to assess the impact on outcomes and related costs. We ran logistic regressions to identify barriers and facilitators to implementation of CPG. RESULTS From 2019 to 2022, 653 LA were included from 24 centers. 69 residents performed and coordinated data collection. We identified low compliance with recommendations on peritoneal irrigation (PI) (25.73%), abdominal drains (AD) (34.68%), and antibiotic stewardship (34.17%). Poor compliance on PI and AD was associated to higher infectious complications in uncomplicated AA. Hospitalizations were significantly longer in non-compliance except for PI in uncomplicated AA, and costs significantly higher, exception made for antibiotic stewardship in complicated AA. The strongest barriers to CPG implementation were complicated AA and technically challenging LA for PI and AD. Longer operative times and the use of PI negatively affected antibiotic stewardship in uncomplicated AA. Compliance was higher in teaching hospitals and in emergency surgery units. CONCLUSIONS We confirmed low compliance with standardized items influenced by environmental factors and non-evidence-based practices in complex LA. Antibiotic stewardship is sub-optimal. Not following CPG may not influence clinical complications but has an impact in terms of logistics, costs and on the non-measurable magnitude of antibiotic resistance. Structured educational interventions and institutional bundles are required.

Abstract
Children undergoing appendicectomy for complicated appendicitis are at an increased risk of post-operative morbidity. Placement of an intra-peritoneal drain to prevent post-operative complications is controversial. We aimed to assess the efficacy of prophylactic drain placement to prevent complications in children with complicated appendicitis. A systematic review was performed in accordance with PRISMA guidelines. Cochrane, MEDLINE and Web of Science databases were searched from inception to November 2022 for studies directly comparing drain placement to no drain placement in children ≤ 18 years of age undergoing operative treatment of complicated appendicitis. A total of 5108 children with complicated appendicitis were included from 16 studies; 2231 (44%) received a drain. Placement of a drain associated with a significantly increased risk of intra-peritoneal abscess formation (odds ratio [OR] 1.61, 95% confidence interval [CI] 1.16-2.24, p = 0.004) but there was no significant difference in wound infection rate (OR 1.46, 95% CI 0.74-2.88, p = 0.28). Length of stay was significantly longer in the drain group (mean difference 2.02 days, 95% CI 1.14-2.90, p < 0.001). Although the quality and certainty of the available evidence is low, prophylactic drain placement does not prevent intra-peritoneal abscess following appendicectomy in children with complicated appendicitis.

Abstract
Background To date, the value of prophylactic abdominal drainage (AD) following appendectomy in patients with complicated appendicitis (CA), including adults and children, has yet to be determined. This paper presents a meta-analysis of the effects of prophylactic AD on postoperative complications in patients with CA, with the goal of exploring the safety and effectiveness of prophylactic AD. Methods PubMed, Science Direct, Web of Science, Cochrane Library, and Embase databases were searched for relevant articles published before August 1, 2022. The primary outcomes were the complication rates [overall incidence of postoperative complications, incidence of intra-abdominal abscess (IAA), wound infection (WI), and postoperative ileus (PI), and the secondary outcome was the perioperative outcome]. The meta-analysis was performed with STATA V. 16.0A. Results A total of 2,627 articles were retrieved and 15 high-quality articles were eventually included after screening, resulting in a total of 5,123 patients, of whom 1,796 received AD and 3,327 did not. The results of this meta-analysis showed that compared with patients in the non-drainage group, patients in the drainage group had longer postoperative length of hospitalization (LOH) (SMD = 0.68, 95% CI: 0.01-1.35, P = 0.046), higher overall incidence of postoperative complications (OR = 0.50, 95% CI: 0.19-0.81, P = 0.01), higher incidence of WI (OR = 0.30, 95% CI: 0.08-0.51, P = 0.01) and PI (OR = 1.05, 95% CI: 0.57-1.54, P = 0.01), the differences were statistically significant. However, there was no significant difference in the incidence of IAA (OR = 0.10, 95% CI: -0.10 to 0.31, P = 0.31) between the two groups. The results of subgroup meta-analysis showed that in the adult subgroup, the overall incidence of postoperative complications in the drainage group was higher than that in the non-drainage group (OR = 0.67, 95% CI: 0.37-0.96, P = 0.01). However, there were no significant differences in IAA (OR = 0.18, 95% CI: -0.28 to 0.64, P = 0.45) and WI (OR = 0.13, 95% CI: (-0.40 to 0.66, P = 0.63) and PI (OR = 2.71, 95% CI: -0.29 to 5.71, P = 0.08). In the children subgroup, there were no significant differences in the incidence of IAA (OR = 0.51, 95% CI: -0.06 to 1.09, P = 0.08) between the two groups. The overall incidence of postoperative complications (OR = 0.46, 95% CI: 0.02-0.90, P = 0.04), incidences of WI (OR = 0.43, 95% CI: 0.14-0.71, P = 0.01) and PI (OR = 0.75, 95% CI: 0.10-1.39, P = 0.02) were significantly higher than those in the non-drainage group. Conclusion This meta-analysis concluded that prophylactic AD did not benefit from appendectomy, but increased the incidence of related complications, especially in children with CA. Thus, there is insufficient evidence to support the routine use of prophylactic AD following appendectomy.

Abstract
OBJECTIVE To investigate the effect of laparoscopic purse-string sutures in adult complicated appendicitis treatment. METHODS The data of 568 adult cases of complicated appendicitis treated by laparoscopic appendectomy at the Hefei Second People's Hospital, Anhui Province, China, from September 2018 to September 2021 were analysed retrospectively. The patients were divided into two groups: 295 cases in the laparoscopic purse-string suture treatment group (observation group) and 273 cases in the simple Hem-o-lok® clamp treatment group (control group). The baseline data collected included age, gender, preoperative body temperature, leukocyte count and percentage of neutrophils and the surgery time. The postoperative data collected included antibiotic treatment duration, drainage tube placement time and the incidence of complications. RESULTS There were no significant differences in the baseline data of the two groups, including age, gender, preoperative body temperature, leukocyte count and neutrophil percentage (all P > 0.05). Compared with the control group, the postoperative hospital length of stay, duration of antibiotic treatment, the recovery time of peripheral white blood cell and neutrophil counts and the incidence of postoperative complications in the observation group were significantly decreased (P < 0.05). CONCLUSION Purse-string sutures can effectively reduce the incidence of postoperative complications after a laparoscopic appendectomy for adult acute complicated appendicitis. There was faster postoperative recovery when patients' appendiceal stumps were treated with laparoscopic purse-string sutures.

The necessity of abdominal drainage for patients with complicated appendicitis undergoing laparoscopic appendectomy: a retrospective cohort study. World J Emerg Surg 2022; 17:16. [PMID: 35300711 PMCID: PMC8928608 DOI: 10.1186/s13017-022-00421-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 03/08/2022] [Indexed: 12/17/2022] Open
Abstract
Background This study aimed to evaluate the necessity of abdominal drainage after laparoscopic appendectomy in patients with complicated appendicitis. Methods Patients with acute appendicitis undergoing laparoscopic appendectomy at two hospitals between January 2014 and December 2018 were retrospectively included. Complicated appendicitis was defined as the American Association for the Surgery of Trauma (AAST) grade ≥ II. The patients were classified according to the AAST grade and the indwelling of abdominal drainage. The postoperative surgical outcomes and recovery were compared among patient groups to evaluate the impact of abdominal drainage for patients with complicated appendicitis undergoing laparoscopic appendectomy. Results A total of 1241 patients was retrospectively included. Among them, there were 820 patients with simple appendicitis (AAST grade I) and 421 patients with complicated appendicitis (AAST grade ≥ II). For complicated appendicitis, the drainage group (N = 192) tended to harbor more overall complications, intra-abdominal abscess formation, time to resume a soft diet, and the postoperative length of hospitalization (P = 0.0000 for all). Multivariate logistic regression confirmed that abdominal drainage increased the risk of overall complications [Odds ratio (OR) 2.439; 95% confidence interval (CI) 1.597–3.726; P ≤ 0.0001] and failed to decrease the risk of intra-abdominal abscess formation (OR 1.655; 95% CI 0.487–5.616; P = 0.4193). Multivariate linear regression analysis also showed that the drainage group harbored longer postoperative length of hospitalization (Coefficients: 20.697; 95% CI 15.251–26.143; P < 0.0001) and time to resume a soft diet (Coefficients: 45.899; 95% CI 34.502–57.297; P < 0.0001). Conclusions Abdominal drainage did not prevent overall complications in patients with complicated appendicitis; paradoxically, it delayed the convalescence. Our results discourage the routine use of abdominal drainage and suggest that abdominal drainage should be performed sparingly.
