[Surgery in chronic pancreatitis. II. Late results following non-resection operations].

Between 1966 and 1985, 994 patients with chronic pancreatitis were treated at a University Surgical Department, 346 by drainage or diversion procedure, 339 by resection and 309 conservatively. The most frequent non-resecting procedures were: pancreatic pseudocyst drainage in 146, biliary-digestive tract anastomosis in 80, gastro-enterostomy in 15, biliary-tract revision in 58 and pancreatic duct drainage in 7 patients. More than half the patients had previously been operated on at least once. Overall postoperative death rate was 6.6%. Of those operated on up to 1983, whose subsequent course was analysed retrospectively, 16% had died (mean observation period 4.6 years). As many as 29% of patients had further bouts of pancreatitis. Weight remained steady or increased in 82%, the number of those with diabetes increased by 6%. All but 12% remained free of pain postoperatively or had only minor and occasional symptoms. Alcohol abuse decreased markedly. If alcohol consumption remained moderate (less than 50 g daily), late mortality rate was definitely decreased. Drainage or diversion procedures and pancreas resection are not competitive but complementary methods in chronic pancreatitis. Imaging techniques have helped the trend towards more conservative management.
