Abstract

A 46-year-old man was referred to further treatment for a 20 mm submucosal tumor at the gastric angle found during a medical check-up. Endoscopic ultrasonography and chest abdominal contrast-enhanced CT revealed the tumor was located at the 4th(proper muscular)layer of the posterior wall of the gastric antrum and slightly enhanced. No metastasis was found. Although a biopsy failed to reveal an accurate diagnosis, GIST was clinically suspected. A robotic distal gastrectomy was planned to manage the residual gastric stricture. The intraoperative findings indicated possible passage of the remnant stomach; therefore, local resection was performed. The patient's postoperative course was uneventful, and he was discharged on postoperative day 9. A histopathological examination confirmed the diagnosis of a PAS-positive, S100-positive granular cell tumor with no nuclear atypia. These findings suggest that use of the robotic approach could help determine the stomach resection extent.
