Successful EUS-guided retrograde pancreatic duct stent?placement for refractory pancreaticojejunostomy stricture?after pancreaticoduodenectomy with a?forward-viewing?echoendoscope

摘要

A 62-year-old man underwent pancreaticoduodenec- tomy with modified Child reconstruction for a duct- type intraductal papillary mucinous neoplasm localized at the pancreatic head. One year later, he was admitted because of pancreatitis associated with pancreaticojeju- nostomy stricture (PJS). We performed ERCP with a small-caliber colonoscope, successfully identified the anastomosis, and cannulated the pancreatic duct. Then, we dilated the PJS using a balloon catheter and de- ployed a 5F plastic stent. However, 2 months after ERCP, the patient experienced upper-abdominal discomfort, and laboratory test results showed elevated serum pancreatic enzymes.
