Efficacy of Endoscopically Created Bypass Anastomosis in Treatment of Afferent Limb Syndrome: A Single-Center Study.

Afferent limb syndrome is a postoperative complication of gastrointestinal surgery, resulting from obstruction of a biliary-enteric limb. Surgery has been the cornerstone of treatment for this condition, but advances in endoscopic and percutaneous techniques could offer less-invasive options. Creation of an internal endoscopic anastomosis between the obstructed afferent limb and an adjacent gastrointestinal lumen can relieve symptoms and might provide a long-term solution. We report the efficacy of endoscopic treatment of afferent limb syndrome using lumen-apposing self-expandable metal stents to create 3 types of enteric anastomoses: a jejunojejunostomy, 2 gastrojejunostomies, and a duodenuojejunostomy in patients who developed afferent limb obstruction following a resection for pancreaticobiliary cancer.
