    Abstract:
    A 63-year-old man underwent proximal gastrectomy for gastrointestinal stromal tumor(GIST)of the stomach 19 years ago. Local recurrence of GIST of the stomach occurred 13 years later, and the tumor was resected. Since then, he had adjuvant chemotherapy. Six years later, computed tomography revealed a soft-tissue shadow at the left lateral side of the stomach, and positron emission tomography also revealed fluorodeoxyglucose uptake at the same site. The recurrence of GIST was suspected, and therefore laparoscopic resection was performed. The operative time was 70 minutes. Blood loss was 10 g. Immunohistochemical examination showed positivity for c-kit and CD34, leading to a diagnosis of recurrence of GIST. The postoperative course was uneventful, and the patient was discharged on the fifth postoperative day. At present, the patient is alive without adjuvant chemotherapy 13 months since surgery. GIST may recur 10 years or more after surgery. Therefore, long-term surveillance seems to be mandatory.
