Ramanathan R, et al. - Researchers sought for the associations between preoperative biliary drainage (percutaneous or endoscopic) and 30-day outcomes via analyzing patients undergoing liver resection between 2014 and 2016 for non-disseminated hilar and intrahepatic cholangiocarcinoma (CCA) using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. As per findings, increased postoperative complications were noted in association with PBD among patients undergoing hepatectomy for proximal CCA. Data thereby suggest that avoidance of routine preoperative biliary drainage might reduce short-term complications.
