This study introduces a new, safe, and quick laparoscopic cholangiography technique using the Kumar clamp. This method avoids complications associated with traditional cystic duct cannulation for intraoperative bile duct imaging.

Area of Science:

  • Surgical Innovation
  • Minimally Invasive Procedures
  • Gastrointestinal Surgery

Background:

  • Laparoscopic cholangiography traditionally uses cystic duct cannulation, posing practical challenges and risks.
  • Potential hazards include iatrogenic common bile duct injuries due to misidentification of anatomy.

Purpose of the Study:

  • To describe a novel, safe, and efficient alternative method for intraoperative cholangiography.
  • To overcome the limitations and risks associated with conventional laparoscopic cholangiography techniques.

Main Methods:

  • A Kumar clamp is applied across the infundibulum.
  • A 23-gauge sclerotherapy needle is inserted through the clamp into the infundibulum.
  • Cholangiography is performed before dissection in the triangle of Calot.

Main Results:

  • The technique is easy, quick, and safe.
  • No pathology was missed in any cases.
  • No complications were reported with this novel method.

Conclusions:

  • The Kumar clamp method offers a safe and effective alternative for laparoscopic cholangiography.
  • Performing cholangiography before Calot's triangle dissection minimizes risks of common bile duct injury.
  • This technique enhances patient safety in laparoscopic procedures involving the bile duct.
