A case of chronic pancreatitis associated with infected pseudocyst after endoscopic pancreatic stenting

Abstract

Endoscopic treatment of pancreatic pseudocysts yielded good results with low rates of complication. But the complication rate is uncertain. A 47-year-old man was refered to our hospital with a diagosis of pancreatic stones and pseudocyst. Several imaging tests demonstrated a cyst of approximately 70 mm in diameter and pancreatic stones in the main pancreatic duct at the pancreatic head. Because of communication of the cyst with the main pancreatic duct, we performed EPS (endoscopic transpapillary stenting of the pancreatic duct). EPS resulted in the infection of pseudocyst. Therefore, percutaneous drainage of the cyst was performed to improve the general condition. After ESWL and EPS treatment, the pancreatic stones and cyst had disappeared. His clinical course was uneventful without recurrence of the pancreatic stones and pseudocyst at twenty months after treatment.
