Abstract
PURPOSE: This study aimed to assess clinical efficacy and long-term patient outcomes in individuals with malignant hilar biliary obstruction (MHBO) that had been treated via insertion of a stent with a radioactive seed strand (RSS). MATERIAL AND METHODS: A total of 84 MHBO patients were treated via either normal stent insertion (n = 48) or stent with RSS insertion (n = 36) from January 2015 to December 2018. RESULTS: The technical success rates of normal stent insertion and stent with RSS insertion were 93.8% (45/48) and 97.2% (35/36), respectively (p = .632), with clinical success rates of 93.3% (42/45) and 100% (35/35), respectively (p = .252). In these two patient groups, 11 and seven patients, respectively, suffered from stent dysfunction (p = .637). In the normal and RSS groups, median stent patency was 165 and 225 days, respectively (p < .001). All patients in the present study died due to tumor progression, with median survival times of 188 and 250 days in the normal and RSS stent groups, respectively (p < .001). CONCLUSION: Relative to normal stent insertion, combined stent with RSS insertion can effectively prolong both stent patency and patient survival in patients with MHBO.
