Abstract
Endoscopic retrograde cholangio-pancreatography (ERCP) is recommended for stone removal in patients with a positive intra-operative cholangiogram (IOC). However, the false positive rate of IOC is as high as 60%, and the complication rate of ERCP (including infection, bleeding, perforation, and pancreatitis) ranges from 3 to 11%. Our aim is to evaluate the role of endoscopic ultrasound (EUS) in clarifying which patients required ERCP, and to determine if any clinical, biochemical, or radiologic features indicate a greater likelihood of choledocholithiasis.Patients and methods:We undertook a prospective blinded study of EUS prior to ERCP for consecutive patients with a positive IOC.
