BackgroundCurrently, the percutaneous approach is the mainstream of treatment for malignant bilioenteric anastomotic stricture (BAS). However, there is no consensus on the optimal bile drainage method since previous studies on malignant BAS related jaundice are very limited. The purpose of the study is to compare self-expandable metallic stent placement with catheter drainage for malignant bilioenteric anastomotic stricture in terms of e cacy and safety.
Materials and MethodsThis study included 54 patients with malignant bilioenteric anastomotic stricture treated from March 2016 to February 2020. 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 de ned as successful placement of stent or drainage catheter in the appropriate position; clinical success was de ned 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.
