Biliary tract reconstruction in liver transplantation

Area of Science:

• Hepatobiliary Surgery
• Transplantation Immunology
• Surgical Innovation

Background:

• Biliary complications remain a significant concern following liver transplantation, impacting patient outcomes.
• Previous biliary reconstruction methods often involved stents or T tubes, which can lead to complications.
• The donor gallbladder's role in post-transplant biliary access and management has been explored.

Purpose of the Study:

• To evaluate a novel biliary reconstruction technique in liver transplantation that omits stents and T tubes.
• To assess the incidence and types of biliary complications associated with this technique.
• To identify risk factors for biliary complications in liver transplant recipients.

Main Methods:

• A series of 161 consecutive liver transplants were analyzed.
• A specific biliary reconstruction method was employed, retaining the donor gallbladder for radiologic access.
• Data on anastomotic and gallbladder-related complications, mortality, and pre-transplant surgical history were collected.

Main Results:

• The overall frequency of biliary complications was 13.6% (15 anastomotic, 7 gallbladder-related).
• A Roux-en-Y reconstruction with anastomosis to the donor duct demonstrated the lowest anastomotic complication rate (2.2%).
• Prior upper abdominal surgery, particularly shunting procedures, was identified as a major risk factor for biliary complications.

Conclusions:

• Refined biliary reconstruction techniques, including the method described, have reduced mortality from biliary complications after liver transplantation.
• The described technique, avoiding stents and T tubes while utilizing the donor gallbladder, appears effective in managing biliary reconstruction.
• Pre-transplant upper abdominal surgery is a significant risk factor that warrants careful consideration in liver transplant candidates.
