Abstract
A 60-year-old man with a history of chronic alcoholic abuse was admitted to our hospital because of massive ascites. MRI demonstrated a cystic lesion at the pancreas body and contiguous leakage of the fluid along the hepato-duodenal ligament. ERP was performed. After confirming leakage of contrast material from the pancreatic pseudocyst, a 5Fr naso-pancreatic drainage catheter was placed to bridge the cyst. Massive ascites disappeared in two months subsequent to the drainage. A 5Fr, 7 cm-long plastic stent was placed to bridge the cyst for additional one month. There has been no sign of recurrence of pancreatic pseudocyst and leakage after stent removal. Endoscopic pancreatic stenting is considered to be an effective treatment for pancreatic ascites.
