Abstract:
Objective:To investigate the feasibility and efficacy of endoscopic placement of transpapillary parallel-style bilateral metal stents for malignant hilar biliary stricture.Methods:A total of 55 patients with malignant hilar biliary stricture (Bismuth Ⅱ-Ⅳ) were treated with an improved endoscopic drainage technique (endoscopic transpapillary parallel-style bilateral metal stenting) from January 2012 to December 2018 in Shanghai Oriental Hepatobiliary Surgery Hospital. The technical success rate, clinical success rate, incidence of complications, success rate of endoscopic re-intervention, stent patency and overall survival were analyzed.Results:The technical success rate of endoscopic placement of bilateral metal stents was 96.4% (53/55), the clinical success rate was 96.2% (51/53), and the early complication incidence was 13.2% (7/53). The median stent patency was 9.2 months (95% CI: 8.0-10.3 months), the success rate of endoscopic re-intervention of bilateral biliary systems was 92.3% (12/13), and the median overall survival was 6.7 months (95% CI: 4.7-8.8 months). Conclusion:This modified technique of bilateral metal stent placement is safe and effective for malignant hilar biliary stricture that is unsuitable for surgery.
