Rubber transcystic drainage reduces the post-removal biliary complications in liver transplantation: a matched case-control study

Abstract

Purpose: Bile duct (BD) complications continue to be the "Achilles' heel" of liver transplantation, and the utilization of bile duct drainage is still on debate. We describe the results of a less invasive rubber trancystic biliary drainage (TBD) compared to a standard silicone T-tube (TT).

Methods: The transplanted patients (n = 248), over a period of 5 years with a TBD (n = 20), were matched 1:2 with control patients with a TT (n = 40). Primary end points were the overall incidence of BD complications and graft and patient survival. Secondary end points included the complications after the drainage removal.

Results: Although the bile duct leakage rates were not significantly different between both groups, the TT group had a significantly higher rate of overall 1-year BD stenosis (40 versus 10 %) (p = 0.036). Three-year patient/graft survival rates were 83.2/80.1 and 84.4/84.4 % for the TT and TBD groups, respectively. The postoperative BD complications, after drainage removal (peritonitis and stenosis), were significantly reduced (p = 0.011) with the use of a TBD.

Conclusion: The use of rubber TBD in liver transplant recipients does not increase the number of BD complications compared to the T-tube. Furthermore, less BD anastomotic stenosis and post-removal complications were observed in the TBD group compared to the TT group.
