Abstract
''Groove pancreatitis'', a form of segmental pancreatitis affecting th e head of the pancreas, is localized within the ''groove'' between pan creas head, duodenum, and common bile duct. Differentiation between gr oove pancreatitis and pancreatic head carcinoma is often difficult. We report a case of groove pancreatitis in which a hypoechoic mass betwe en the duodenal wall and pancreas was clearly imaged, and narrowing of the second portion of the duodenum and bile duct stenosis were also f ound. The diagnosis was confirmed by surgery (pylorus-preserving pancr eato duodenectomy). The patient was relieved from abdominal pain post operation. Up to the present, the patient has been good condition. We review the clinicopathologic and radiologic features of groove pancrea titis in the Japanese literature and discuss the possible role of Sant orini's duct in its pathogenesis. We consider that impacted protein pl ugs in Santorini's duct are a pathogenic factor in the development of groove pancreatitis. Therefore, the findings of Santorini's duct on en doscopic retrograde pancreatography are very important in the diagnosi s of groove pancreatitis. Groove pancreatitis presents various clinica l features, such as biliary stenosis, duodenal stenosis, and pancreati c mass, and often masquerades as pancreatic head carcinoma. This condi tion should be kept in mind in the differential diagnosis of pancreati c head carcinoma.
