BACKGROUND AND OBJECTIVES: Balloon enteroscopy-assisted ERCP (BE-ERCP) has become the first-line therapy for biliopancreatic anastomotic strictures. However, it is not always successful, and salvage methods have not been established. This study aimed to evaluate the outcomes of EUS-guided transanastomotic drainage using a forward-viewing (FV) echoendoscope. PATIENTS AND METHODS: Of eight cases wherein BE-ERCP treatment failed due to severe or complete benign anastomotic stricture, seven cases underwent EUS-guided choledochojejunostomy, and EUS-guided pancreaticojejunostomy was applied in one case after intubating an FV echoendoscope into the anastomotic site. RESULTS: The success rate of reaching the target site was 100% (8/8) for patients after modified Child resection. The median time to reach the anastomosis was 5 min (range: 3-17 min), and the technical success rate for drainage was 75% (6/8). The median total procedure time was 33.5 min (range: 22-45 min) for six successful cases. Cautery dilatation catheters were necessary to dilate the puncture site in all cases, and no early complications were observed. During the follow-up period (median: 13.3 months [range: 6.5-60.3]), recurrence of the stricture occurred in one case, and a stent-free status was achieved after 6-12 months of stent placement in five cases. CONCLUSIONS: EUS-guided transanastomotic drainage using an FV echoendoscope is a feasible and safe rescue technique for the management of benign severe biliopancreatic anastomotic strictures.
