Laparoscopic Transcholedochal Exploration
Laparoscopic transcholedochal common bile duct exploration (LTCD) is a versatile technique for the treatment of choledocholithiasis based on the traditional technique of open common duct exploration. LTCD permits access to the proximal and distal biliary ducts and allows the surgeon to use a variety of instruments to clear the bile duct of stones and ensure biliary drainage. A stepwise approach to ductal clearance starting with the simplest interventions first is recommended. LTCD is an advanced laparoscopic procedure and requires appropriate patient selection and suturing skill to reduce the risk of complications. Options for closure of the choledochotomy include primary closure, closure over a T-tube, and primary closure with a biliary stent. A large experience with LTCD shows that this procedure can be performed safely, but there is a higher risk of bile leak compared to transcystic exploration that requires vigilance by the surgeon.
