Abstract Background While the management of acute gallstone pancreatitis (AP) has recognised guidelines, there are wide variations in compliance with these in various institutions for different reasons. The primary objective of this review was to evaluate the effects of implementing proactive management strategies on a specialist biliary firm receiving most biliary emergency admissions by protocol on the incidence of index admission laparoscopic cholecystectomy (LC) for AP. The secondary aims were to study the admission to LC interval, if such policy was safe and how it can help the optimisation of outcomes of AP. Method Analysis of prospectively collected data from AP patients treated by a specialist biliary unit dedicated to index admission LC and single session laparoscopic management of bile duct stones. Almost all patients were referred to the unit as soon as the diagnosis of AP was made. Only patients with severe pancreatitis on imaging or requiring intensive care were not included in the index admission pathway and subsequently underwent delayed surgery. Routine MRCP and ERCP were not part of the management protocol. Following clinical optimisation patients had LC with routine cholangiography (IOC). and if necessary bile duct exploration. Results 495/6140 patients were identified (8%), 70% females. Median age was 55 years. 92.3% had suspected ductal stones, half with jaundice. 11.9% had previous episodes. Only 6.2% had MRCPs and 2% ERCPs. Admission to LC interval was 5 days. 33.2% required bile duct explorations. LC difficulty grade was III to V in 37.2%. The median operative time was 62 minutes with no conversions, ductal injuries or mortality. Complications occurred in 9.2%, including 14 persistent pancreatitis/collections resulting in 6 of 25 readmissions. Two re-operations resulted from t-tube complications. Median hospital stay was 7 days, 72% having had only one admission. Conclusion Index admission LC on all AP patients fit for surgery is perfectly safe in the specialist setting. It optimises preoperative radiological investigations and endoscopic interventions and ,subsequently, a third of the patients require bile duct exploration. Implementing definitive surgical interventions during the index admission for AP offers a substantial reduction in hospital stay, re-admission rates and an overall decrease in hospital attendances. This not only yields significant cost benefits for the health service but also enhances the quality of life for patients.
