Management of Gallstone Pancreatitis

Introduction to Guidelines

The American Gastroenterological Association and the European Society of Gastrointestinal Endoscopy recommend specific management strategies for patients with gallstone pancreatitis, including imaging of the bile duct and consideration of cholecystectomy during the same hospital admission 1, 2

Early cholecystectomy (within 2 weeks of presentation) is recommended for patients with mild gallstone pancreatitis to prevent recurrent pancreatitis, with the American Gastroenterological Association suggesting it be performed during the index admission 1
Delayed cholecystectomy is recommended for patients with signs of lung injury and systemic disturbance until these have resolved, while delaying beyond 2-4 weeks after discharge increases the risk of potentially fatal recurrent pancreatitis 1, 2

Urgent ERCP within 72 hours of presentation is recommended for patients with gallstone pancreatitis, with endoscopic sphincterotomy and stone extraction performed as needed 1, 3
ERCP should be reserved for patients with clear evidence of CBD stones, as unnecessary ERCP increases procedural risks without benefit 4

Intraoperative cholangiography should be considered for patients with intermediate to high probability of CBD stones, with systematic evaluation of the biliary tree essential before or during cholecystectomy to prevent overlooking common bile duct stones 1, 2
Routine intraoperative cholangiography is unnecessary in patients with mild gallstone pancreatitis and normalizing bilirubin levels 5

Same admission cholecystectomy is strongly recommended after ERCP for choledocholithiasis, reducing the risk of recurrent biliary events by up to 92% compared to delayed or no cholecystectomy, according to the American College of Gastroenterology 5, 3
For patients with mild gallstone pancreatitis who undergo ERCP, same admission cholecystectomy is still advised despite reduced risk of recurrent pancreatitis, due to increased risk for other biliary complications 5
Age alone should not be a contraindication to cholecystectomy after ERCP, with same-admission cholecystectomy in elderly patients (≥65 years) associated with lower risk of readmission for biliary disease and fewer complications 5, 3
For patients unfit for surgery, ERCP with sphincterotomy alone provides adequate long-term therapy, although these patients should be informed about the increased risk of recurrent biliary events 3
Laparoscopic cholecystectomy can be performed during the index admission, as early as the second hospital day, if the patient is clinically improving, with cholecystectomy deferred in patients with peripancreatic fluid collections until fluid collections resolve or stabilize and acute inflammation ceases 5
