Abstract
A 59-year-old woman complaining of tarry stool underwent gastrointestinal endoscopy and total colonoscopy. However, the hemorrhage point was not clear, so she was referred to our hospital.
Double-balloon endoscopy of the small intestine revealed a 30 mm submucosal tumor at the jejunum.
Since gastrointestinal stromal tumor (GIST) of the jejunum was suspected, we injected black ink as preoperative marking. The location of the tumor was easily identified by the marking, and we performed laparoscopic partial resection of the jejunum.
Histopathological diagnosis was a low grade GIST.
For GIST of the small intestine, preoperative double-balloon endoscopy is useful for accurate diagnosis and an appropriate treatment.
