Technical Aspects of Bile Duct Evaluation and Exploration: An Update

Abstract

Consensus guidelines recommend patients with symptomatic cholelithiasis and suspected choledocholithiasis have common bile duct exploration (CBDE) at the time of cholecystectomy to prevent downstream problems. Despite superiority of single-stage cholecystectomy with CBDE, 2-stage precholecystectomy/postcholecystectomy with endoscopic clearance of the duct is commonly practiced. This is related to inadequate training in minimally invasive techniques, lack of technical support for efficient and safe CBDE, and surgeons' inexperience with complex biliary pathologic condition. This article provides a framework for evaluating and treating patients with CBD pathologic condition with an emphasis on technical aspects of CBDE and preoperative planning and preparation.
