Objective: To compare the incidence of biliary complications after liver transplantation in patients undergoing choledochocholedochostomy reconstruction with or without T tube in a multicenter, prospective, randomized trial.
Summary background data: Several reports have suggested that biliary anastomosis without a T tube is a safe method of biliary reconstruction that could avoid complications related to the use of T tubes. No large prospective randomized trial has so far been published to compare the two techniques.
Methods: One hundred eighty recipients of orthotopic liver transplantation were randomly assigned to choledochocholedochostomy with (n = 90) or without (n = 90) a T tube in six French liver transplantation centers. All types of biliary complications were taken into account.
Results: The overall biliary complication rate was increased in the T-tube group, even though these complications did not lead to an increase in surgical or radiologic therapeutic procedures. The major significant complication was cholangitis in the T-tube group; this did not occur in the other group. The incidence of biliary fistula was 10% in the T-tube group and 2.2% in the group without a T tube. Other biliary complications were similar. The complication rate of cholangiography performed with the T tube was greater than with other types of biliary exploration. The graft and patient survival rates were similar in the two groups.
Conclusion: This study is the first large prospective, randomized trial of biliary complications with or without a T tube. The authors found an increase in the biliary complication rate in the T-tube group, which was linked to minor complications. The T tube did not provide a safer access to the biliary tree compared with the others types of biliary explorations. The authors recommend the performance of choledochocholedochostomy without a T tube in liver transplantation.
