Aspirin exposure and its association with metal stent patency in malignant biliary obstruction: a large international multicenter propensity score-matched study

Stent dysfunction is common following endoscopic retrograde cholangiopancreatography (ERCP) with self-expanding metal stent (SEMS) insertion in malignant distal biliary obstruction (MDBO). Chronic aspirin exposure (ASA-E) has been previously shown to potentially decrease this risk. We aim to further ascertain the protective effect of ASA and to identify other predictors of stent dysfunction.
