Clinical update on acute cholecystitis and biliary pancreatitis: between certainties and grey areas.

Abstract

Acute calculous cholecystitis (ACC) and acute biliary pancreatitis (ABP) are significant complications of gallstone disease. This review aims to provide a comprehensive analysis of current management practices for ACC and ABP. The Tokyo Guidelines (TG) and World Society of Emergency Surgery (WSES) guidelines recommend early laparoscopic cholecystectomy (ELC) as the treatment of choice for ACC. High-risk patients may benefit from alternative treatments like biliary drainage, with emerging techniques such as endoscopic drainage showing promise. ABP requires prompt diagnosis and intervention. The Revised Atlanta Classification (RAC) criteria are used for diagnosis, with endoscopic retrograde cholangiopancreatography (ERCP) and cholecystectomy as primary treatments. Minimally invasive approaches are preferred for managing complications like infected pancreatic necrosis, with the endoscopic step-up method showing superior outcomes. The management of ACC and ABP continues to evolve. Future research is needed to refine guidelines further and address existing controversies, ultimately improving patient outcomes in these acute biliary conditions.
