Abstract

BACKGROUND: Pancreatic pseudocyst is the most common cystic lesion of pancreas, which is formed with leakage of pancreatic juice by pancreatic duct injury, surrounded by around intraperitoneal organs and tissue.
METHODS
The study subjects consist of 18 patients who undergone primarily percutaneous catheter drainage(PCD) from January of 1995 to December of 1998 at Pusan National University Hospital.
RESULTS
The peak incidence was in the age group of 20 to 40 years and male gender was somewhat dominant. The cause of pancreatic pseudocyst was mainly trauma(61.1%), the most common location of injury site was body of pancreas. The initial diameter of pancreatic pseudocyst was above 6 cm(72.2%) and the size was reduced in 13 cases(72.2%) of 18 cases during treatment. Mostly the amount of drainage through PCD was below 100mL(55.6%) and the amount was decreased in 13 cases during treatment. Spontaneous resolution of pancreatic pseudocyst was occurred in 11 cases, among them 3 cases were recurred. Persistent or recurred cases were undergone secondary procedure, internal drainage in 6 cases, retrial of PCD in 2 cases, distal pancreatectomy in 1 case, zther in 1 case.
CONCLUSION
The percutaneous catheter drainage performed within initial 6 weeks for spontaneous resolution of pancreatic pseudocyst or maturation of cystic wall is considered as alternative treatment of pancreatic pseudocyst.
