Watch this detailed video on Laparoscopic Repair of Common Bile Duct (CBD) Injury, demonstrating step-by-step minimally invasive techniques for effective management. Perfect for surgeons, trainees, and medical professionals seeking practical insights through video learning.

Common bile duct (CBD) injury is the most serious complication of laparoscopic cholecystectomy. Recently, laparoscopic techniques have been used in the management of postoperative bile leak and CBD injury. In this video, We have demonstrated a method of repair on CBD injury, the approach to its diagnosis and management, and reports of laparoscopic management techniques. We combined this video with our experience in laparoscopic methods to highlight diagnostic and therapeutic options. Laparoscopic techniques can be used to prevent, diagnose and treat CBD injuries. Intraoperatively, CBD injury can be prevented in the case of short cystic duct with the use of a loop ligature or transfixing suture, and it can be diagnosed using intraoperative cholangiography or other visualization techniques or by ICG.

Causes of CBD Injury

CBD injuries usually occur due to:

• Misidentification of anatomical structures during surgery

• Inexperience or inadequate exposure of the biliary anatomy

• Severe inflammation or scarring in cases of acute cholecystitis

Types of CBD Injury

The classification of CBD injuries helps guide management. The Strasberg classification is widely used:

• Type A: Minor bile leak from cystic duct or small ducts in the liver bed

• Type B & C: Occlusion or transection of accessory ducts

• Type D: Lateral injury to the major bile duct

• Type E: Complete transection of the bile duct with or without stricture

Laparoscopic Repair: Indications

Laparoscopic repair is indicated in cases where:

• The injury is identified intraoperatively or early postoperatively

• The patient is hemodynamically stable

• The surgical team has adequate expertise in advanced laparoscopic biliary surgery

Step-by-Step Laparoscopic Repair

1. Patient Positioning and Port Placement
   The patient is placed in a supine or slightly reverse Trendelenburg position. Standard laparoscopic ports are inserted for optimal access to the hepatobiliary region.

2. Identification of Injury
   The site and extent of bile duct injury are carefully assessed. Intraoperative cholangiography may be used to delineate the biliary anatomy.

3. Debridement and Preparation
   Edges of the bile duct are debrided gently to healthy tissue. Any associated bile leak or hematoma is cleared.

4. Primary Repair or Reconstruction

   • Primary End-to-End Anastomosis: For small, clean transections without tension, end-to-end repair using absorbable sutures is performed.

   • Roux-en-Y Hepaticojejunostomy: For extensive injuries or segmental loss, a biliary-enteric anastomosis is created laparoscopically to restore bile flow.

5. Stenting and Drainage
   A T-tube or internal stent may be placed to ensure bile drainage and prevent stricture formation. A drain is positioned near the repair site.

6. Closure and Postoperative Care
   Ports are removed, and wounds closed. Patients are monitored for bile leak, infection, or stricture formation. Early mobilization and follow-up imaging ensure successful recovery.

Advantages of Laparoscopic Repair

• Minimally invasive with reduced postoperative pain

• Shorter hospital stay and faster recovery

• Better visualization of biliary anatomy due to magnification

• Lower risk of wound infection and adhesion formation

Challenges and Considerations

• Requires advanced laparoscopic skills and experience

• Not all injuries are suitable for laparoscopic repair; some may need open surgery

• Early recognition of injury is critical to success

• Careful patient selection is essential

Conclusion

Laparoscopic repair of common bile duct injury is a safe and effective technique when performed by experienced surgeons. With meticulous technique, careful identification of anatomy, and proper postoperative care, patients can achieve excellent outcomes with minimal morbidity. Early recognition and timely intervention remain the keys to successful management of CBD injuries.
