Cholangiopancreatography, endoscopic

The largest use of endoscopic techniques is in the examination of the gastrointestinal tract. Upper intestinal endoscopy is the examination of the esophagus, stomach, and proximal duodenum. Colonoscopy is the examination of the colon, large intestine, and in some cases the distal parts of the small intestine. Cholangiopancreatography is the examination of the biUary tree and pancreas. 

Only one study to date has been conducted on the treatment of acute pancreatitis with antioxidants. Clemens et al. (1991) were unable to show any difference in the incidence or severity of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in a prospective, randomized, double-blind, placebo-controlled trial of allopurinol. However, Salim (1991) performed a similar trial of the effect of allopurinol and DMSO in patients with pain from recurrent pancreatitis, and found significant benefit. On the basis that depletion of antioxidants is important in the pathogenesis of chronic pancreatitis, the administration of a cocktail of antioxidants was assessed for its effect on pain in this disease. Treatment with a combination of organic selenium, d-carotene, vitamins C and E, and methionine was of benefit in the initial pilot study, and in a placebo-controlled trial (San-dilands etal., 1990 Uden et al., 1990).

O In the Western hemisphere, acute pancreatitis is caused mainly by ethanol use/abuse and gallstones. Other common causes of acute pancreatitis include hypertriglyceridemia, endoscopic retrograde cholangiopancreatography (ERCP), and autodigestion due to early activation of pancreatic enzymes. Numerous medications have also been implicated as causes of acute pancreatitis (Table 20-1).

Removal of biliary tract gallstones with endoscopic retrograde cholangiopancreatography or surgery usually resolves AP and reduces the risk of recurrence. Surgery may be indicated in AP to treat pseudocyst, pancreatic abscess, and to drain the pancreatic bed if hemorrhagic or necrotic material is present. 

Endoscopic retrograde cholangiopancreatography is the most sensitive and specific diagnostic test, but it is reserved for patients in whom the diagnosis cannot be established by imaging techniques because of the potential for complications.
