Peponis T, et al. - Researchers examined the influence of preoperative endoscopic retrograde cholangio-pancreatography (ERCP) on the risk of surgical site infections (SSI) following laparoscopic cholecystectomy via analyzing patients admitted to an academic hospital from 2010 to 2016, who were older than 18, and had a laparoscopic or a laparoscopic converted to open cholecystectomy for complicated biliary tract disease. Findings revealed an association of preoperative ERCP with a threefold increase in the risk of SSIs after laparoscopic cholecystectomy. Only conversion to open and preoperative ERCP independently predicted SSIs. A longer hospital length of stay was evident with preoperative ERCP.
