[Surgery for Multiple Gastrointestinal Stromal Tumors of the Small Intestine in Patients with Neurofibromatosis Type 1 - A Report of Three Cases].

We report 3 cases of multiple GIST of the small intestine in 3 patients with NF1 who have been followed for over 5 years. All patients presented with melena, and tumors of the small intestine suspected to be GIST were found on endoscopy. We performed partial resections of the small intestine for all 3 patients. After surgery, 1 patient had residual tumors that gradually enlarged during 8 year 2 months and another had residual tumors that have been stable for 8 years. In the third patient, we resected all the tumors, and there has been no sign of recurrence in 6 year 1 month.
