Treatment of Gallstone Pancreatitis

Initial Assessment and Management

The American Gastroenterological Association recommends that all patients with severe acute pancreatitis should be managed in a high dependency unit or intensive therapy unit with full monitoring and systems support 1, 2
Dynamic CT scanning should be obtained within 3-10 days of admission using non-ionic contrast to assess for pancreatic necrosis and peripancreatic fluid collections in patients with acute pancreatitis 3, 4
Prophylactic antibiotics, such as intravenous cefuroxime, may be considered in severe acute pancreatitis to prevent local and septic complications, with a strength of evidence based on moderate-quality studies 2, 4

Urgent therapeutic ERCP with sphincterotomy should be performed in patients with predicted or actual severe pancreatitis of gallstone etiology, cholangitis, jaundice, or dilated common bile duct, as recommended by the European Society of Gastrointestinal Endoscopy 1, 3
The procedure is best performed within the first 72 hours after the onset of pain, with a high level of evidence supporting its effectiveness in reducing morbidity and mortality 1
ERCP should always be performed under antibiotic cover to prevent infection, based on strong evidence from clinical trials 1, 3
Failure of the patient's condition to improve within 48 hours despite intensive initial resuscitation is an indication for urgent ERCP and sphincterotomy, with a moderate level of evidence supporting this approach 3, 5

Patients should have their gallstones eradicated by laparoscopic (or open) cholecystectomy within 2-4 weeks, preferably during the same hospital admission, as recommended by the Society of American Gastrointestinal and Endoscopic Surgeons 1, 3
Preoperative assessment of the common bile duct by liver biochemistry and ultrasound examination should be performed to identify potential complications, with a low level of evidence supporting its routine use 3, 6

For severe gallstone pancreatitis, cholecystectomy should be delayed until signs of lung injury and systemic disturbance have resolved, based on moderate-quality evidence 1

For patients who cannot undergo cholecystectomy due to high surgical risk, ERCP with sphincterotomy is an alternative definitive treatment, reducing the risk of recurrent pancreatitis, with a moderate level of evidence supporting its effectiveness 1
Failing to perform ERCP in patients with cholangitis or biliary obstruction can lead to increased morbidity and mortality, with a high level of evidence supporting the importance of prompt intervention 1, 3

Determine severity of pancreatitis using Ranson criteria or other scoring systems, with a high level of evidence supporting the use of these tools in clinical practice 4
For severe cases, consider urgent ERCP within 72 hours if cholangitis, jaundice, or dilated CBD, based on moderate-quality evidence 1
Delay cholecystectomy until resolution of systemic inflammation, with a moderate level of evidence supporting this approach 1
