Laparoscopic Cholecystectomy with Intraoperative Cholangiogram and Antegrade Biliary Stenting in Acute Gallstone Pancreatitis: A Pilot Study.

To demonstrate feasibility and efficacy of simultaneous intraoperative cholangiogram (IOC) and antegrade biliary stenting (ABS) with laparoscopic cholecystectomy (LC) compared with preoperative biliary investigation and delayed LC in acute gallstone pancreatitis (AGP). A retrospective case-control study was performed comparing patients who had a simultaneous IOC ± ABS with LC at index admission with those who had delayed LC in the treatment of AGP. 74 patients were included in this study from January 2016 to October 2018. All patients who underwent LC for AGP were included in a prospective database with 1 year follow-up. 30 (40.5%) patients underwent simultaneous IOC ± ABS with LC, 11 of these required ABS insertion. 2 (6.7%) patients also underwent magnetic resonance cholangiopancreatography (MRCP). No patients underwent endoscopic retrograde cholangiopancreatography (ERCP). No patients were readmitted with AGP or symptomatic gallbladder. Mean length of total hospital admission was 10.1 days. 44 (59.5%) patients underwent delayed LC. Of this cohort, 7 (15.9%) patients underwent ERCP and 19 (43.2%) underwent MRCP. In total, there were 19 (43.2%) readmissions in this group with pancreatitis or symptomatic gallbladder. Mean length of total hospital admission was 13 days. In our pilot study we demonstrated that performing simultaneous IOC ± ABS with LC is a feasible option in the secondary care setting. Using this surgical technique, we have demonstrated a reduction in readmissions with AGP and symptomatic gallbladder while also reducing the number of CBD investigations required. Using simultaneous IOC ± ABS with LC reduced the mean total length of stay in hospital.
