RESUMEN
BACKGROUND AND AIMS: Anastomotic strictures are well-known complications after bilioenterostomy. Endoscopic procedures are usually not possible in patients with a bilioenterostomy. Hence, percutaneous transhepatic biliary drainage (PTBD) has become the treatment of choice for the management of these patients. The main goal of the present study was to analyze the long-term follow-up of PTBD in such patients. METHODS AND PATIENTS: Between January 1996 and December 2006, 44 patients with benign anastomotic stricture after bilioenterostomy were identified by an analysis of the PTBD database, hospital charts, and cholangiograms. RESULTS: In 27/44 patients the percutaneous transhepatic biliary drain was successfully removed after 19.9 +/- 16.1 months (treatment success in 61.4 %). During a mean follow-up of 53.7 +/- 28.4 months after removal of the drain, no evidence was found of recurrent strictures in these patients. Ten out of 44 patients carry permanent drains (22.6 % of patients with ongoing treatment, mean follow-up 46.4 +/- 54.7 months) without the option for further surgery owing to concomitant disease (n = 2) or because they refused further surgery (n = 8). In 7 out of 44 patients (16 %) PTBD treatment was deemed to have failed and the patients underwent repeat operation. CONCLUSIONS: PTBD should be considered the treatment of choice in patients with benign anastomotic stricture after bilioenterostomy, especially after stricturing of a hepatojejunostomy.
