A 59-year-old man, who had been treated for chronic pancreatitis for 7 years, complained of vomiting and loss of appetite. Barium meal study, hypotonic duodenography, and endoscopic examination revealed stenosis of the descending duodenum. Tumor markers carcinoembryonic antigen and carbohydrate antigen 19-9 were within normal range. Barium meal study which was performed 7 years earlier also revealed duodenal stenosis at the same site, which suggested benign stenosis due to chronic pancreatitis rather than pancreatic cancer. Endoscopic retrograde pancreaticography showed dilatation of the main pancreatic duct without irregularity; however the duct of Santorini was not demonstrated. Abdominal CT showed no mass or calcification in the pancreas head. Laparotomy findings supported the diagnosis of groove pancreatitis and the patient underwent duodeno-duodenostomy.
