Changing concepts in the surgical management of pancreatic pseudocysts.
A 27-year experience in the surgical management of 160 patients with pancreatic pseudocysts was reviewed. Sixty-eight patients treated from 1964 to 1981 (Group I) were compared to 92 patients managed from 1982 to 1990 (Group II). During the recent period, computed tomography (CT) scanning, endoscopic retrograde cholangiopancreatography (ERCP), selective visceral angiography, and percutaneous catheter drainage (PCD) techniques were available. The mean age of patients was similar in both groups (45 vs 44 years). Most pseudocysts in both periods represented complications of chronic pancreatitis due to alcohol abuse (82% vs 87%). Pancreatitis-associated complications occurring before management (fistula, obstruction, hemorrhage) were more frequent in Group II (19% vs 40%, P less than .05). There was a significant increase in the number of patients managed with external drainage in Group II (10% vs 52%) attributable to the use of PCD as definitive therapy in 46 per cent of patients in the recent period. Use of internal drainage procedures (cystgastrostomy, cystduodenostomy, cystjejunostomy) decreased in Group II (38% vs 16%, P less than .05). The use of lateral pancreaticojejunostomy (LPJ) combined either with caudal resection or cyst drainage has remained constant in both periods (32% vs 24%, NS). Patient morbidity was similar (26% vs 28%, NS) and mortality improved in Group II (9% vs 1%, P less than .05). Internal or external drainage for pseudocyst is often not definitive because of the underlying ductal disease. The authors' current approach is to manage large symptomatic cysts either with internal drainage or PCD; they employ octreotide acetate in the management of persistent pancreatic fistula following external drainage.(ABSTRACT TRUNCATED AT 250 WORDS)
