Towards T-tube free laparoscopic bile duct exploration: a methodologic evolution during 300 consecutive procedures

Area of Science:

• Minimally Invasive Surgery
• Gastrointestinal Surgery
• Biliary Tract Surgery

Background:

• Laparoscopic common bile duct exploration (CBDE) is often perceived as complex by surgeons.
• Endoscopic retrograde cholangiopancreatography (ERCP) is frequently used for bile duct stones but involves a second procedure and associated morbidity.
• Alternative laparoscopic techniques for CBDE have been developed to address these challenges.

Purpose of the Study:

• To develop a simple, reproducible, and safe laparoscopic common bile duct exploration (CBDE) technique.
• To achieve high stone clearance rates with minimal morbidity and mortality.
• To establish a one-stage treatment option for patients with gallbladder and common bile duct stones.

Main Methods:

• A total of 300 consecutive patients underwent laparoscopic common bile duct exploration (CBDE) between August 1991 and February 1997.
• Procedures utilized either a transcystic approach (58%) or choledochotomy (42%).
• Fluoroscopic guidance was employed for stone extraction.

Main Results:

• Successful laparoscopic stone clearance was achieved in 90% of patients (271/300).
• The overall mortality rate was 0.3% (1 death), with major morbidity in 7% of patients (22).
• The success rate improved over time, with only two failures in the last 100 procedures.

Conclusions:

• Laparoscopic transcystic basket extraction is a quick, successful, and safe method for common bile duct stones.
• Primary bile duct closure, with or without stenting, is preferred over T-tube insertion after choledochotomy.
• A one-stage laparoscopic procedure is feasible for most patients, avoiding external biliary drainage or ERCP.
