SP8.1.4 Iatrogenic gallbladder perforation during laparoscopic cholecystectomy and outcomes: a systematic review and meta-analysis

Abstract

Abstract Aims to compare the outcomes of iatrogenic gallbladder perforation versus no gallbladder perforation in patients undergoing laparoscopic cholecystectomy. Methods In compliance with PRISMA statement standards, electronic databases were searched to identify all studies comparing the outcomes of iatrogenic gallbladder perforation versus no gallbladder perforation in patients undergoing laparoscopic cholecystectomy. The outcome of interest included surgical site infection (SSI), postoperative collection, operative time and length of hospital stay. Random effects modelling was applied to calculate pooled outcome data. The certainty of evidence was assessed using GRADE system. Results A total of 5366 patients from 11 studies were included. Analysis of 5366 patients from 11 observational studies suggested that iatrogenic gallbladder perforation during laparoscopic cholecystectomy does not increase the risk of SSI (OR 1.48, 95% CI 0.57–3.86, P=0.42) and postoperative collection (RD 0.00, 95%CI -0.00–0.01, P=0.41) but may result in longer operative time (MD 10.28, 95% CI 7.40–13.16, P <0.00001) and length of hospital stay (MD 0.51, 95%CI 0.15–0.87, P=0.005). The results remained consistent through sensitivity analyses. The quality of available evidence was judged to be moderate and the GRADE certainty of the evidence was judged to be high. Conclusions Relatively robust evidence with high level of certainty suggests that iatrogenic gallbladder perforation during laparoscopic cholecystectomy may not increase the risk of SSI and postoperative collection but may result in longer operative time and length of hospital stay. Whether prompt retrieval of spilled stones, adequate peritoneal irrigation, and intraoperative use of prophylactic antibiotic contribute to the above findings remains unknown.
