註釋Background and Aim: The main disadvantage of plastic stents is the high rate of stent occlusion. The usual replacement interval of biliary plastic stents is 3 months. This study aimed to investigate if a shorter interval of 6-8 weeks impacts the median premature exchange rate (mPER) in benign and malignant biliary strictures. Methods: All cases with endoscopic retrograde cholangiopancreatography (ERCP) and plastic stent placement were retrospectively analyzed since establishing an elective replacement interval of every 6-8 weeks at our institution and mPER was determined. Results: A total of 3979 ERCPs (1199 patients) were analyzed, including 1262 (31.7%) malignant and 2717 (68.3%) benign cases, respectively. The median stent patency (mSP) was 41 days (range 14-120) for scheduled stent exchanges, whereas it was 17 days (1-75) for prematurely exchanged stents. The mPER was significantly higher for malignant (28.1%, 35-50%) compared with benign strictures (15.2%, 10-28%), P
