Objectives: Liver transplant represents the criterion standard therapy for end-stage liver disease. Biliary complications after liver transplant have shown an increased trend and are characterized by anastomotic and nonanastomotic stenoses. Material and Methods: This retrospective single-center observational study included 217 patients who under - went liver transplant between January 2004 and December 2014; 18 patients had anastomotic (8.3%) and 29 (13.4%) had non-anastomotic stenoses. Patients with and without biliary stenosis were compared with regard to their preoperative, intraoperative, and postoperative parameters and donor characteristics. Patients with biliary stenosis were divided into 3 cohorts according to the type of endoscopic treatment performed (single plastic, multiple plastic, and fully covered self-ex - pandable metal stents). We compared the patients with different types of endoscopic biliary drainages for length and type of stenosis, presence of stones, time of onset and treatment, number of procedures, complications, and success rate. Results: Preoperative Child-Pugh and Model for End- Stage Liver Disease scores, complication and re - operation rates, and donor age were significantly higher in the stenosis group. We found no statistical differences other than length of stenosis between patients with multiple stents and self-expanding metal stents. Conclusions: Preoperative recipient conditions and postoperative morbidities may represent risk factors for development of biliary strictures. Consequently, the optimal endoscopic treatment should be tailored to the type and the onset of stenosis and the patient’s condition.
