Abstract
　Duodenal stenosis is well known as a complication of peptic ulcer. It sometimes occurs　associated with "groove pancreatitis" in adults. We treated such a case in a child, with findings resembling those of groove pancreatitis.
　A 6-year-old boy was admitted having experienced recurrent vomiting and stomachache over at least three years. His fluororoentgenography revealed a gastrectasia and a stenosis of the duodenal cap. We found endoscopically that he had a duodenal ulcer. We examined him with US, CT and MRI, which showed marked swelling in the head of the pancreas. A palliative gastroduodenostomy was performed, and no mass lesion was found in the pancreas during the operation. His postoperative course has been uneventful for six months.
　Postoperatively, disappearance of the abnormal swelling of the pancreas was confirmed by using US and CT. We finally diagnosed him as having duodenal stenosis due to duodenal ulcer associated with some kind of pancreatitis such as groove pancreatitis.
