Abstract
The patient was a 64-year-old man who had visited another hospital because of tarry stool in 2004. Abdominal CT revealed an intra-abdominal 10-cm-sized tumor in December 2006. In January 2007, he complained of nausea and abdominal fullness and was diagnosed as having ileus by abdominal x-ray film. At laparotomy, we found a 180° small intestinal volvulus. The tumor was located in the ileum 240 cm from the end of Bauhin's valve and 270 cm from the Treitz'ligament. The tumor and partial ileum were removed and an ileoileostomy was performed. Post operative pathological diagnosis was intermediate-grade GIST of the small intestine. GIST of the small intestine associated with small bowel volvulus is a very rare disease.
