ABSTRACT
Background & Aims:
Biliary complications (BC) following liver transplantation (LT) are responsible for significant morbidity. No technical procedure during reconstruction has been associated with a risk reduction of BC. The placement of an intraductal removable stent (IRS) during reconstruction followed by its endoscopic removal showed feasibility and safety in a preliminary study. This multicentric randomised controlled trial aimed at evaluating the impact of an IRS on BC following LT.Methods:
This multicentric randomised controlled trial was conducted in 7 centres from April 2015 to February 2019. Randomisation was done during LT when a duct-to-duct anastomosis was confirmed with at least 1 of the stump diameters ≤7 mm. In the IRS group, a custom-made segment of a T-tube was placed into the bile duct to act as a stake during healing and was removed endoscopically 4 to 6 months post LT. The primary endpoint was the incidence of BC (fistulae and strictures) within 6 months post LT. The secondary criteria were complications related to the IRS placement or extraction, including endoscopic retrograde cholangio-pancreatography (ERCP)-related complications.Results:
In total, 235 patients were randomised 117 in the IRS group and 118 in the control group. BC occurred in 31 patients (26.5%) in the IRS group vs. 24 (20.3%) in the control group (p = 0.27), including 16 (13.8%) and 15 (12.8%) strictures, respectively. IRS migration occurred in 24 patients (20.5%), cholangitis in 1 (0.9%), acute pancreatitis in 2 (1.8%), and difficulty during endoscopic extraction in 19 (19.4%). No predictive factor for BC was identified.Conclusions:
IRS does not prevent BC after LT and may require specific endoscopic expertise for removal. Trial registration number ClinicalTrialsgov NCT02356939 (https//clinicaltrials.gov/ct2/show/NCT02356939?term=NCT02356939&draw=2&rank=1). Laysummary:
Liver transplantation is a life-saving treatment for many patients with end-stage liver disease. However, it can be associated with complications involving the bile duct reconstruction. Herein, the placement of a specific stent called an intraductal removable stent was trialled as a way of reducing bile duct complications in patients undergoing liver transplantation. Unfortunately, it did not help preventing such complications.
