Risk Factors Associated With Residual Stones in Common Bile Duct Via T Tube Cholangiography After Common Bile Duct Exploration

摘要

Open surgery with common bile duct (CBD) exploration and T tube drainage are still traditionally performed in a large amount of selected patients with cholelithiasis and choledocholithiasis. Confirmation of CBD clearance via T tube cholangiography after surgery is a routine procedure before T tube removal. The present study aims at investigating potential risk factors associated with residual stones in CBD via T tube cholangiography.
