title: [Classification and choice of surgical procedures for chronic pancreatitis].
abstract: OBJECTIVE
  To explore the classification, choice of surgical procedures and the clinical outcome of surgical management for chronic pancreatitis.
  
  
  METHODS
  54 patients with chronic pancreatitis undergoing operation in our hospital from 1983 to 2004 were analyzed retrospectively, who were divided into chronic calcifying pancreatitis and chronic obstructive pancreatitis according to the clinical manifestations.
  
  
  RESULTS
  There were 41 men (76%) and 13 women (24%) with a mean age of 54 years. The cause of chronic pancreatitis was alcohol related in 25 cases (46%), cholelithiasis in 21 (39%), and previous episodes of acute pancreatitis in 18 (33%). Clinical manifestations included abdominal pain in 38 cases (70%), obstructive jaundice in 27 cases (50%). There existed a significant difference in some clinical materials between the two groups of chronic calcifying pancreatitis and chronic obstructive pancreatitis, which might mean the different pathologic basis in the two kinds of chronic pancreatitis. A total of 34 patients underwent nine different operations without perioperative deaths. Both the Puestow procedure and the pancreatoduodenectomy was safe and achieved pain relief in a large percentage of patients, which could also improve the exocrine function whereas the endocrine function remained unchanged. Addition of biliary bypass to the Puestow procedure was suitable for the patients with stenosis of common bile duct. Jaundice was the main manifestation in the patients with the inflammatory mass in the head of the pancreas and Whipple's procedure or other resectional procedures should be performed for them. Only drainage of bile duct had a better outcome for the relief of jaundice, but its effect to pancreas need to be further evaluated.
  
  
  CONCLUSIONS
  The clinicopathologic characteristics of obstructive chronic pancreatitis was more variable and the surgical management should be also different for individuals.
