Biliary decompression in hilar obstruction. Round ligament approach
Insights
This study presents a novel surgical approach for biliary decompression in patients with obstructed hepatic hilus. The technique accesses the left hepatic duct, bypassing difficult anatomy for effective treatment.
Area of Science:
- Hepatobiliary Surgery
- Interventional Radiology
- Surgical Anatomy
Background:
- Biliary obstruction poses challenges when hepatic hilus access is compromised by tumors or scar tissue.
- Standard surgical approaches may be unfeasible in complex cases.
Purpose of the Study:
- To describe an alternative method for biliary decompression in challenging cases of biliary obstruction.
- To detail the anatomical landmarks and surgical steps for accessing the left hepatic duct.
Main Methods:
- Surgical access to the left hepatic duct via the left intersegmental plane.
- Identification of the left hepatic duct superior to the left portal vein.
- Division of the round ligament and liver parenchyma in an avascular plane.
Main Results:
- Successful exposure of the left hepatic duct is achievable using this approach.
- Biliary decompression can be performed via tube drainage or Roux-en-Y hepaticojejunostomy.
Conclusions:
- This technique offers a viable alternative for biliary decompression when the hepatic hilus is inaccessible.
- It provides a crucial option for managing complex biliary obstruction cases.
Abstract:
In some patients with biliary obstruction, access to the hepatic hilus is hindered by extensive tumor or by dense vascular scar tissue. In such patients, the biliary tract may be decompressed via the left hepatic duct away from the affected hilus. Access to the left hepatic duct in the left intersegmental plane is gained by dividing the round ligament, freeing it from the undersurface of the liver, and following it to its junction with the left portal vein. The left hepatic duct, which lies superior to the vein, is exposed by dividing the liver overlying the round ligament in the relatively avascular plane between the lateral and the medial segments of the left hepatic lobe. Decompression can be effected by simple tube drainage or, if the duct is large enough, by Roux-en-Y hepaticojejunostomy.
