Management of Acute Pancreatitis

Initial Management

The American Gastroenterological Association recommends initiating goal-directed fluid therapy immediately upon presentation in patients with acute pancreatitis 1
Early oral feeding should be started within 24 hours as tolerated, rather than keeping the patient nil per os, according to the American Gastroenterological Association 1
If oral feeding is not tolerated, enteral nutrition (nasogastric or nasojejunal route) is preferred over parenteral nutrition, as suggested by the American Gastroenterological Association 1
The American Gastroenterological Association recommends providing 35-40 kcal/kg/day with protein intake of 1.2-1.5 g/kg/day 2
Supplementing with B-complex vitamins is critical, especially in alcohol users, as recommended by the American Gastroenterological Association 2

The American Gastroenterological Association suggests assessing severity using the APACHE II scoring system (cutoff of 8) to guide triage decisions 4
For predicted severe disease (APACHE II >8), contrast-enhanced CT should be performed after 72 hours to evaluate for pancreatic necrosis, as recommended by the American Gastroenterological Association 4
Patients with severe disease require ICU or HDU management with full monitoring, according to the British Society of Gastroenterology 5
For mild disease (80% of cases), management on a general ward with basic vital sign monitoring is sufficient, as suggested by the British Society of Gastroenterology 5

The American Gastroenterological Association recommends performing cholecystectomy during the initial admission rather than after discharge, even when gallbladder sludge is the biliary source 1
Cholecystectomy should be performed once the patient has recovered, preferably during the same hospitalization, to prevent recurrent pancreatitis, as recommended by the British Society of Gastroenterology 7
ERCP is indicated only if cholangitis is present or if there is failure to improve within 48 hours despite intensive resuscitation in severe gallstone pancreatitis, according to the British Society of Gastroenterology 7

The American Gastroenterological Association recommends implementing brief alcohol intervention during admission, which reduces alcohol consumption by approximately 41 g/week 1
Brief alcohol intervention should use the FRAMES model: Feedback about dangers, Responsibility, Advice to abstain, Menu of alternatives, Empathy, and Self-efficacy encouragement, as suggested by the American Gastroenterological Association 2
Alcohol withdrawal syndrome should be treated with benzodiazepines as the treatment of choice, according to the American Gastroenterological Association 2

The American Gastroenterological Association recommends obtaining serum amylase or lipase, triglyceride level, calcium level, and liver chemistries (bilirubin, AST, ALT, alkaline phosphatase) at admission to establish the etiology of acute pancreatitis 4
The etiology should be established in at least 75-80% of cases, and no more than 20-25% should be classified as "idiopathic", as suggested by the British Society of Gastroenterology 5

A multimodal approach to analgesia is recommended, with hydromorphone preferred over morphine or fentanyl in non-intubated patients, according to the American Gastroenterological Association 2
