Transjugular insertion of biliary stent in patients with malignant biliary obstruction complicated by ascites with/without coagulopathy: a prospective study of 12 patients.

ABSTRACT

PURPOSE: In patients with malignant biliary obstruction complicated by massive ascites, when endoscopy fails, safe routes for biliary decompression are needed as an alternative to percutaneous approach. We aimed to evaluate the safety and effectiveness of transjugular insertion of biliary stent (TIBS) in patients with malignant biliary obstruction complicated by massive ascites with or without coagulopathy. METHODS: From March 2012 to December 2017, a total of 12 consecutive patients with malignant biliary obstructions treated with TIBS were enrolled in this study. Five patients had jaundice and cholangitis, while seven had jaundice only. Clinical parameters including technical and clinical success rates and complications following TIBS were evaluated. Overall survival and stent occlusion-free survival were assessed using Kaplan-Meier analysis. RESULTS: The indications for transjugular approach were massive ascites with (n=2) or without (n=10) coagulopathy. TIBS was technically successful in 11 of 12 patients. Clinical success was defined as successful internal drainage and was achieved in eight patients. The mean serum bilirubin level was initially 13.9±6.3 mg/dL and decreased to 4.9±5.3 mg/dL within 1 month after stent placement (P = 0.037). Two patients had procedure-related complications (hemobilia). During the follow-up period (mean, 30 days; range, 1-146 days), all 12 patients died of disease progression. The median overall survival and stent occlusion-free survival times were 19 days (95% confidence interval [CI], 16-22 days) and 19 days (95% CI, 12-26 days), respectively. There was no stent dysfunction in the eight patients that had successful internal drainage. CONCLUSION: TIBS appears to be safe, technically feasible, and clinically effective for patients with malignant biliary obstruction complicated by massive ascites with or without coagulopathy.
