Scissor-type knife precut in balloon enteroscopy–assisted ERCP for patients with difficult biliary cannulation and surgically altered anatomy (with video)

Balloon enteroscopy-assisted ERCP (BE-ERCP) is useful for treating pancreatobiliary disease in patients with surgically altered anatomy (SAA); however, biliary cannulation, including the precut technique, is often challenging. This study aimed to examine the feasibility of scissor-type knife precutting (SKP) during BE-ERCP in patients with SAA.This retrospective study investigated consecutive patients who underwent BE-ERCP and SKP for difficult...
