Postoperative choledochoscopy through the T-tube tract

Area of Science:

• Gastroenterology
• Surgical Endoscopy
• Biliary Tract Surgery

Background:

• Retained biliary calculi management is challenging.
• Current methods like T-tube irrigation and basket catheters have limitations.

Purpose of the Study:

• To evaluate the effectiveness of postoperative choledochoscopy for retained biliary stones.
• To assess the feasibility of using a choledochofiberscope via T-tube tract.

Main Methods:

• Retrospective analysis of 17 patients undergoing postoperative choledochoscopy.
• Utilized a choledochofiberscope passed through the T-tube tract.
• Dilation of T-tube tract was performed when necessary.

Main Results:

• Choledochoscopy was consistently effective in evaluating filling defects.
• Successful removal of difficult or multiple retained stones was achieved.
• T-tube tract dilation was easily accomplished.

Conclusions:

• Postoperative choledochoscopy is a valuable tool for retained biliary stone management.
• The technique allows direct visualization and stone removal.
• Larger T-tube designs may further enhance access and visualization.
