Abstract
The purpose of the study was to compare self-expandable metallic stent placement with catheter drainage for malignant bilioenteric anastomotic stricture in terms of efficacy and safety. 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 1week after the procedure, compared with baseline. Complications, duration to stent/catheter malfunction, and overall survival were evaluated. 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 (130days) than in the Catheter group (82days; P = 0.010). The median overall survival was also significantly longer in the Stent group (187days) than in the Catheter group (118days; P = 0.038). Self-expandable metallic stent placement might be better than internal-external catheter drainage for malignant bilioenteric anastomotic stricture in terms of the duration before stent/catheter malfunction and patient survival.
Highlights
The percutaneous approach is the mainstream of treatment for malignant bilioenteric anastomotic stricture (BAS)
Self-expandable metallic stent placement may be better than internal-external catheter drainage for malignant bilioenteric anastomotic stricture in terms of the duration before stent/catheter malfunction and patient survival
Malignant bilioenteric anastomotic stricture (BAS) is an uncommon condition caused by tumor recurrence at the anastomotic site after surgery [1, 2]
Summary
The purpose of the study is to compare self-expandable metallic stent placement with catheter drainage for malignant bilioenteric anastomotic stricture in terms of efficacy and safety. The purpose of this study was to compare self-expandable metallic stent (SEMS) placement with internal-external catheter drainage for malignant BAS in terms of efficacy and safety
