췌장낭종의 (膵臟囊腫) ERCP 소견 및 임상 (臨床) 고찰

ERCP has some advantages in the diagnosis of pancreatic cyst. One is that ERCP can find the ultrasonographically undetectable cyst which is less than 5 cm located in the left upper quadrant. Also ERCP provides the information about the ductal anatomy underlying diseases of pancreatic cyst. Authors report the clinical study S: ERCP finding of 10 cases of pancreatic cyst. The results were as follows 1) Out of 938 cases of ERCP, the pancreatic cysts were 10 cases and 1 case was mucinoous cystadenoma of pancreas and others were pseudocysts. 2) The etiologic causes of pancreatic pseudocysts were acute and chronic pancreatitis(4 cases) malignancy(2 cases) trauma(1 case) and unknown(2 cases). 3) There is no specific age-incidence and male to female ratio was 4: 1 4) The most common site of pseudocyst was tail and the mucinous cystadenoma was located in the head. 5) The most common chief complaints were upper abdominal pain & palpable abdominal mass and serum amylase was elevated in 4 cases & leukocytosis in 3 cases. 6) The diagnosis by UGI-series was pancreatic cyst(3 cases), retroperitoneal tumor(2 cases) normal(2 cases) and by G.I echo, pancreatic cyst(4 cases) retroperitoneal cystic tumor(1 case) & normal(1 case). 7) The complication after ERCP is absent except mild transient elevation of serum amylase 8) The complications of pancreatic pseudocyst were infection(2 cases) k retroperitoneal rupture(1 case) and tbe frequency rate was 33% 9) The ERCP finding was variable. In 5 cases, we have demonstrated the communication from the pancreatic duct system to the cyst with the filling of dye and they are small cysts located in the parenchyme. Other findings were the displacement & compression defect of CBD by the head cyst and the complete obstruction, stenosis and displacement of the pancreatic duct
