A 58‐year‐old man presented with a 2‐month history of nausea and vomiting. Blood levels of hepatic enzymes and pancreatitis markers were slightly elevated. Hypotonic duodenographic and endoscopic examinations revealed stenosis encircling the descending duodenum. A computed tomography (CT) scan showed inflammatory changes in the head of the pancreas and thickening of the duodenal wall. Magnetic resonance cholangiography demonstrated stenosis of the intrapancreatic segment of the common bile duct and diffuse dilatation of the main pancreatic duct, without irregularity. At laparotomy, microscopic examination of a needle biopsy specimen of the head of pancreas revealed no evidence of malignancy. Distal gastrectomy with Billroth II anastomosis was performed. Microscopically, fibrous thickening of the duodenal wall, serositis and hyperplasia of Brunner's glands were found. The presence of duodenal stenosis due to segmental pancreatitis, referred to as groove pancreatitis, was confirmed. The elevated blood levels of pancreatitis markers returned to the normal range 8 months after the operation. Ultrasonic echography and abdominal CT also revealed a marked reduction in dilatation of the extrahepatic bile duct and the main pancreatic duct. In patients suspected of having pancreatic carcinoma or regional pancreatitis, groove pancreatitis should be included in the differential diagnosis.
