Which of the following statements about chronic pancreatitis is/are correct?

E. For patients with disabling chronic pancreatitis and a dilated pancreatic duct with associated stricture formation, a longitudinal pancreaticojejunostomy (Peustow procedure) is an appropriate surgical option.

DISCUSSION: Chronic pancreatitis is a clinical entity that includes recurrent or persistent abdominal pain with evidence of exocrine and endocrine pancreatic insufficiency. While chronic pancreatitis may result from repeated episodes of acute pancreatitis, not all patients with recurring acute pancreatitis progress to chronic pancreatitis. The most common causes of chronic pancreatitis include alcohol abuse, hyperparathyroidism, congenital anomalies of the pancreatic duct, pancreatic trauma, and cystic fibrosis. The most useful radiographic tests in patients with suspected chronic pancreatitis are CT and endoscopic retrograde cholangiopancreatography (ERCP). Mesenteric angiography has no role in the evaluation of most patients with chronic pancreatitis. Patients with disabling chronic pancreatitis who require operative intervention are candidates for a longitudinal pancreaticojejunostomy (Peustow procedure) if pancreatography demonstrates a dilated pancreatic duct. Total pancreatectomy is rarely performed because of the significant problems associated with labile insulin sensitivity, steatorrhea, and weight loss.
