Endoscopic biliary stenting facilitates safe and early removal of T-tube in liver transplant patients

AIM: Duct to duct anastomosis in orthotopic liver transplant (OLT) patients have been traditionally performed with a t-tube in place for 3 to 6 months. Following removal of the t-tube a high incidence of biliary leakage has been reported. METHODS: Prospective study to evaluate the role of endoscopic biliary stenting to facilitate early and uncomplicated t-tube removal. All patients with duct to duct biliary anastomosis who had a t-tube in situ, from January 1998 to December 2002 were included in this study. RESULTS: There were 29 patients eligible for the study. Eight patients were not included due to early death. A protocol t-tube cholangiogram was performed in all patients, (median 12 days; range 4-47 days) followed by an endoscopic stent insertion (median 37 days; range 20-55 days). The stent was removed later (median 84 days; range 45-133 days). All complications related to the procedure were noted. Stent insertion was successful in all cases. In 2 patients a second endoscopic retrograde cholangiopancreatography (ERCP) was necessary, either because of failure to cannulate the papilla or to reposition the stent. There was a patient who presented a biliary leak due to stent displacement requiring a laparotomy. There were two further biliary leaks, one of them in an asymptomatic patient, which were managed conservatively. In addition 1 patient developed a mild case of postERCP pancreatitis. CONCLUSIONS: In liver transplants patients with an end-to-end choledochostomy with a t-tube, endoscopic biliary stenting allows an early removal of the T tube, with few complications.
