The experience of use of percutaneous transhepatic biliary drainages for early biliary complications after liver transplantation.

This study aimed to describe our experience and discuss the results, controversies, and the use of percutaneous transhepatic biliary drainage (PTBD) in patients with biliary complications after liver transplantation (LT). Between November 2009 and August 2020, 76 consecutive patients who underwent 77 LTs (44 deceased donor LTs and 33 living donor LTs [LDLT]) were enrolled retrospectively. Endoscopic therapy as initial approach and PTBD as rescue therapy were used for patients with biliary complications. There were 31 patients (31/76, 40.8%) with biliary complications, and two of them died (2/31, 6.5%). Clinical success rate of endoscopic therapy alone was 71.0% (22/31). The remaining nine patients received salvage PTBD and their clinical results were observed according to whether their intrahepatic bile ducts (IHBDs) was dilated (group A, n = 5) or not (group B, n = 4). In group A, the technical and long-term clinical success rates of PTBD were 100% and 20%, respectively. These five patients received PTBD ranging from 75 to 732 days after their LTs, and no procedure-related complications were encountered. In group B, the technical and long-term clinical success rates of PTBD were 50% and 25%, respectively. Three group B patients (75%) underwent PTBD within 30 days after LDLT and had lethal complications. One patient had graft laceration and survived after receiving timely re-transplantation. The other two patients died of sepsis due to PTBD-related bilioportal fistula or multiple liver abscesses. Our experience showed salvage PTBD played a limited role in biliary complications without dilated IHBDs within 1 month after LT.
