Abstract:
Highlight Ikarashi and colleagues report a case of choledococele treated by endoscopic sphincterotomy and observed on direct peroral cholangioscopy. Histological examination reveals duodenum-like mucosa without atypical changes in the choledochocele. Direct peroral cholangioscopy using an ultra-slim endoscope may be a useful technique for diagnosis and surveillance of choledochocele.
