Abstract

Background: The long-term efficacy of sequential insertion of multiple plastic stents for benign biliary strictures is poorly defined. The aims of this study were to evaluate the long-term outcome (bile duct patency, complications) of this therapy and to identify predictors of a good outcome. Methods: Retrospective review of 29 cases of benign biliary strictures treated with sequential plastic stent insertion in progressively increasing numbers and/or of increasing diameter. Results: Stricture etiology was as follows: postoperative 19 (66%), chronic pancreatitis 9 (31%), and idiopathic 1 (3%). Therapy succeeded in 18 patients (62%) (mean follow-up 48.0 [11.56] months after stent removal). Therapy failed in 11 patients (38%) (mean interval to failure 11.59 [9.79] months after stent removal). The 2 groups of patients in which therapy failed had either a hilar stricture (n = 4, 25% success) or distal common bile duct stricture caused by chronic pancreatitis (n = 9, 44% success). In the remaining cases, therapy succeeded in 13 of 16 (81% success). The observed differences in success rate among subgroups were not statistically significant. There were no ERCP-related deaths. One episode of mild pancreatitis and 2 episodes of cholangitis developed during 126 ERCPs over a period of stent insertion of 36 patient years. Conclusions: In selected patients with benign biliary strictures, sequential endoscopic insertion of multiple biliary stents may lead to long-term success that could be equal to or superior to surgery with minimal morbidity. Hilar strictures and those caused by chronic pancreatitis appear to respond poorly to this therapy.
