Abstract | PURPOSE: MATERIALS AND METHODS: This study included 54 patients with malignant bilioenteric anastomotic stricture treated from March 2016 to February 2021. Twenty-seven patients underwent insertion of self-expandable metallic stent ( Stent group); the remaining twenty-seven patients underwent internal-external catheter drainage ( Catheter group). Technical success was defined as successful placement of stent or drainage catheter in the appropriate position; clinical success was defined as a 20% reduction in serum bilirubin within 1 week after the procedure, compared with baseline. Complications, duration to stent/ catheter malfunction, and overall survival were evaluated. RESULTS: Technical success was achieved in all patients in both groups. In the Stent group, 21 patients received one stent and the other 6 patients required two stents. Clinical success rates were similar between the groups [ Stent group, 92.6% (25/27); Catheter group, 88.9% (24/27)]. There were no major complications. The median duration to stent/ catheter malfunction was significantly longer in the Stent group (130 days) than in the Catheter group (82 days; P = 0.010). The median overall survival was also significantly longer in the Stent group (187 days) than in the Catheter group (118 days; P = 0.038). CONCLUSION:
