Use of Fully Covered Self-Expandable Stent in Biliary Complications After Liver Transplantation: A Case Series

Abstract Aims To present our case series of fully covered self-expandable metallic stents (FCSESs) placed to treat biliary stenosis after liver transplantation and leakage after failure of plastic stenting. Materials and methods We retrospectively reviewed the courses of patients who had undergone liver transplantation with a biliary complication that was treated by an FCSES installed by endoscopic retrograde cholangiopancreatography. We evaluated the following variables: gender, age, indication for transplantation, time between transplant and diagnosis of the complication, number of plastic stents placed before the FCSES, and procedure-related complications. Results From April 2008 to March 2010, 11 patients who had undergone a duct-to-duct anastomosis suffered posttransplant biliary stenosis or leakage with failure of endoscopic treatment using a plastic biliary stent: Namely, eight cases of stenosis and three of biliary leaks. Three patients underwent a papillotomy to place the FCSES, with no significant morbidity. No severe complications were observed after the endoscopic treatments; two patients developed mild pancreatitis; two, hyperamylasemia; and one, mild biliary sepsis. We removed the FCSES after a mean of 280 (range = 173–310) days. Five patients lost the FCSES spontaneously. One patient underwent a choledocojejunostomy and two are waiting biliary surgery. Conclusion We avoided cholangiojejunostomy in 6/9 cases (not including the two deaths). Papillotomy did not engender a greater morbidity. The spontaneous loss of the stent is a problem that need to be resolved.
