Abstract
Here, we report a rare case of primary volvulus of the small intestine. The patient was a 72-year-old man who complained of severe epigastralgia and vomiting after supper was admitted to our hospital. He had no history of laparotomy. Enhanced CT revealed a so-called “whirl sign.” On the basis of the CT findings, we made a diagnosis of volvulus of the small intestine, and emergency operation was performed. A part of the small intestine (about 180-cm long) was found to be twisted clockwise by 360° at the superior mesenteric artery, and excision of this part was performed. On the basis of these findings, we made a diagnosis of primary volvulus of the small intestine because there were no viewes on band, adhesion and malformation.
