We investigated the rate of laparoscopic assisted retrograde cholangiopancreatography (LAERCP) following RYGB. Also, the pre-LAERCP diagnostic workup together with the true rate of choledocholithiasis in patients with or without prior cholecystectomy was investigated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Materials and Methods<\/jats:title>\n                <jats:p>Retrospective cohort study of RYGB and LAERCP performed at the Hospital South West Jutland, University Hospital of Southern Denmark, from 1 January 2013 to 31 May 2022.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>One percent of patients (<jats:italic>n<\/jats:italic>\u2009=\u200913) with a history of RYGB (<jats:italic>n<\/jats:italic>\u2009=\u20091363) underwent LAERCP at our facility during a median follow-up of 60.6\u00a0months.
