Biliary Anastomosis Using T-tube Versus No T-tube for Liver Transplantation in Adults: A Review of Literature.

Abstract

The T-tube-directed biliary anastomosis in orthotopic liver transplantation (OLT) aims to minimize preventable biliary complications, including bile leaks and strictures. Biliary complications in patients with OLT increase the risk of morbidity and mortality. This review paper evaluated the current evidence on the routine use of T-tube reconstruction in OLT cases.A review of prospective, retrospective, observational, cohort studies as well as systematic reviews, meta-analyses, review papers, and opinion papers has been conducted to evaluate the therapeutic potential of T tube-based biliary anastomosis in cases of OLT.Our finding showed a bile leak incidence of 16.6% and 6.6% in T-tube and non-T-tube groups, respectively. The results indicated a lower incidence of anastomotic fistulae in the non-T-tube group (0.6%) compared to the T-tube group (4%). The findings negated statistically significant differences in the three-year actuarial survival rates based on biliary anastomosis with and without T-tube intervention (62.5% vs. 69.8%). The studies revealed a 6-11% and 2-11% incidence of cholangitis in OLT patients with T-tube-based reconstruction and those without a T-tube, respectively, and 26% and 20% incidence of total biliary complications in OLT patients with and without T-tube, respectively. In addition, the findings ruled out the influence of a T-tube on the incidence of perioperative complications, endoscopies, and reoperations in OLT cases.The current evidence correlates the increased incidence of bile leaks, cholangitis, and overall biliary complications with the use of a T-tube during OLT. In addition, T-tube-guided reconstruction has no impact on perioperative complications, overall survival, endoscopies, and reoperations in OLT cases.
