AIM: To investigate the safety and effectiveness of endoscopic therapy with a paclitaxel-eluting balloon (PEB) for biliary anastomotic stricture (AS) after liver transplantation (LT). METHODS: This prospective pilot study enrolled 13 consecutive eligible patients treated for symptomatic AS after LT at the University Hospital of Münster between January 2011 and March 2014. The patients were treated by endoscopic therapy with a PEB and followed up every 8 wk by endoscopic retrograde cholangiopancreatography (ERCP). In cases of re-stenosis, further balloon dilation with a PEB was performed. Follow-up was continued until 24 mo after the last intervention. RESULTS: Initial technical feasibility, defined as successful balloon dilation with a PEB during the initial ERCP procedure, was achieved in 100% of cases. Long-term clinical success (LTCS), defined as no need for further endoscopic intervention for at least 24 mo, was achieved in 12 of the 13 patients (92.3%). The mean number of endoscopic interventions required to achieve LTCS was only 1.7 ± 1.1. Treatment failure, defined as the need for definitive alternative treatment, occurred in only one patient, who developed recurrent stenosis with increasing bile duct dilatation that required stent placement. CONCLUSION: Endoscopic therapy with a PEB is very effective for the treatment of AS after LT, and seems to significantly shorten the overall duration of endoscopic treatment by reducing the number of interventions needed to achieve LTCS.
