In patients with Roux-en-Y (RY) reconstruction for gastric resection, the newly defined "fold disruption" (FD) sign can be useful to distinguish afferent limb from efferent at Y anastomosis when balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) is performed. The FD was as findings of internal folds disrupted toward and continued anastomosis. this prospective observational study, accuracy evaluated those who underwent BE-ERCP after resection RY reconstruction. Of 28 whom could among 30 enrolled patients, identified using 100% accuracy. For other two scope not reach target lumen due severe intestinal adhesion in one reached without recognition other. There no patient judged any reason, such a blurred line, unclear folds, sticky discharge blood coating surface, recognized. highly accurate tool distinguishing This study registered UMIN (issued ID, UMIN000038326).
