2 of the 3 following criteria: (i) abdominal pain consistent with the disease, (ii) serum amylase and/or lipase greater than 3 times the upper limit of normal, and/or (iii) characteristic findings from abdominal imaging 



Fluid--

• Moderately aggressive fluid resuscitation with lactated Ringer's solution should be started (NEJM JW Gen Med Oct 1 2023 and Am J Gastroenterol 2023; 118:2258), defined as a bolus of 10 mL/kg followed by infusion of 1.5 mL/kg/hour (NEJM JW Gen Med Oct 15 2022 and N Engl J Med 2022; 387:989), and additional boluses can be given if a patient has evidence of hypovolemia.

Feeding-- Early oral feeding (within 24–48 hours) should begin with a low-fat solid diet (as opposed to liquid) for patients with mild AP.

Surgery-

 Patients with mild acute biliary pancreatitis should undergo cholecystectomy early, preferably before discharge.

•  Following a second episode of AP with no identifiable cause, in patients fit for surgery, we suggest performing a cholecystectomy to reduce the risk of recurrent episodes of AP.
