Abstract
BACKGROUND: The first-line approach to the treatment of biliary leaks is endoscopic retrograde cholangiopancreatography. A variety of techniques can be used, including sphincterotomy, stenting, a combination of both techniques, or nasobiliary drainage. We performed a systematic review with meta-analysis to define the optimal strategy. METHODS: We searched MEDLINE/PubMed, EMBASE, CENTRAL, Scopus, Google Scholar, and Web of Science until January 2018 for randomized clinical trials, case-control studies, and prospective cohort studies. Data on procedure, success, and complication rate were extracted. Risk of bias was assessed. A network meta-analysis was performed to compare sphincterotomy alone vs. stenting alone vs. combination treatment. Stenting was further stratified into leak-bridging and short stenting. RESULTS: 11 studies out of 5085 references were included. Compared with sphincterotomy alone, the combination of sphincterotomy with leak-bridging stenting had the highest success rate (risk ratio [RR] 1.15, 95 % confidence interval [CI] 0.97 - 1.50), followed by leak-bridging stenting alone (RR 1.10, 95 %CI 0.84 - 1.44). For nonbridgeable leaks, stenting alone had a higher success rate than sphincterotomy alone (RR 1.07, 95 %CI 0.72 - 1.40). The combination of short stents with sphincterotomy had no added benefit (RR 0.94, 95 %CI 0.49 - 1.29). Overall quality of the included studies was considered to be moderate. CONCLUSIONS: We recommend sphincterotomy with stenting if the biliary leak can be bridged. If not, stenting alone with a short stent may be preferred in order to avoid sphincterotomy-related complications. More and larger studies are needed to confirm these findings. © Georg Thieme Verlag KG Stuttgart · New York.
