Abstract
Acute pancreatitis (AP) is a common problem worldwide. Biliary diseases include cholelithiasis, choledocholithiasis, microlithiasis, and biliary sludge, and are likely the most common cause of AP. The diagnosis of AP is based on the presence of a chief complaint of epigastric abdominal pain in an appropriate individual who has a propensity for an etiology of AP and the finding of a laboratory test greater than threefold the upper limit of normal. The initial imaging of a patient with suspected AP should include chest X‐ray and flat and upright abdominal radiographs. The benefits of enteral nutrition begun within three days could reduce the risk of secondary infection and improve the nutritional status of patients with AP. An initial report by Runzi et al. of nonsurgical treatment of 16 patients with severe AP with infected pancreatic necrosis, treated only with an antibiotic regimen adapted to bacteriology and nonsurgical therapy, reported a 12% mortality rate.
