Experience In Diagnosis And Treatment For Pancreatic Pseudocyst

Objective To sum up experiences in diagnosis and treatment for pancreatic pseudocyst(PPC).Methods Clinical records of 38 patients in our hospital from 1993 to 2002 were retrospectively analysed.Results The causes of disease were acute pancreatitis 5 cases(13.1%),chronic pancreatitis 13 cases(34.2%),pancreatic injure 9 cases(23.7%),pancreatic ooperation 2 cases(5.26%) and other causes 9 cases(23.6%).Elevation of amylase in serum and cyst-fluid were 16/25(64%) and 8/16(50%).Accurate rate of B-us and CT seperative was 83.3% and 88.2%.Six patients were non-operation,Cyst in 5 patients were disappeared. 32 patients underwent operation,external drainage was performed in 8,internal drainage in 20,others in 4;8 cases by external drainage ,2 cases had pancreatic fistulas, 1 patient died and 1 patient had of recurred cyst.20 cases by internal drainage,1 patient had recurrence of cyst,2 patients had of multiple cystswere neglected.Quite differenty exists between external drainage and internaldrainage.Total complication rate after operation was 12.5%.Conlusion Imageing technique (B-us or CT) is the most dependent diagnosis method of PPC.When operation is needed,patients with chronic Ppancreatic pseudocysts should be performed firstly by internal drainage.The diagnosis and treatment of multiple cysts shouled be emphasized.
