Brief Summary:
A randomized prospective study will be conducted of patients at Vanderbilt University Medical Center who undergo liver transplantation from March 2014 until approximately 120 patients are randomized. Patients will be randomized to undergo biliary reconstruction with and without stent placement.

Condition or disease Intervention/treatment Phase
Liver Transplant; Complications Device: Bard 5 Fr diameter feeding tube Not Applicable

Detailed Description:
The risk of biliary complications can be related to the type of liver transplant performed and the technique used for reconstruction of the bile duct. One of the main techniques of performing biliary reconstruction is a choledocholedochostomy which can be performed over an anastomotic stent. Although placement of biliary stents is routine practice in many liver transplant centers around the country, there is no evidence to support their use. As of now both the placement and non-placement of a stent are essentially "standard of care". In the investigators' center, many of the transplant surgeons now perform the biliary anastomosis over a pediatric feeding tube which is used as a stent. The practice of using stents in biliary anastomosis is not uniform and there are no established guidelines to support their indiscriminate application. The investigators have designed a prospective randomized trial to evaluate the effect of stent placement on biliary complications and its effect on morbidity.

Arm Intervention/treatment
Experimental: Reconstruction with stent placement
Subjects will undergo biliary reconstruction with stent placement at the anastomosis site.
Device: Bard 5 Fr diameter feeding tube
A pediatric feeding tube is used as a stent over which biliary anastomosis is performed. This is not a permanent stent and generally migrates out on its own.

No Intervention: Reconstruction without stent placement
Subjects will undergo biliary reconstruction without stent placement.

Primary Outcome Measures :
  1. Incidence of biliary complications [ Time Frame: 2 years after transplantation ]
    Biliary complications include biliary strictures, biliary leaks, cholangitis, and stones. The investigators will compare the number of complication between the group that receives the stent and the group that does not.
