    Abstract:
    An 80-year-old woman with anemia presented to our hospital. Upper gastrointestinal endoscopy revealed a 4 cm submucosal tumor(SMT)with a delle and 2 cm SMT in the upper part of the stomach. CT revealed sustained enhancement of both tumors. The posterior tumor was an intraductal growth, and the anterior tumor was an extravascular growth. We performed a laparoscopic gastric local excision for the multiple SMTs. The anterior tumor was resected with an automatic suture instrument. However, the posterior tumor could not be identified from within the abdominal cavity because it was resected while confirming using an endoscope, and all layers were sutured. On histopathological examination, the posterior tumor was 40mm in size, with spindle-shaped atypical cells growing in the submucosal layer. Immunostaining was c-kit(+), CD34(+), S-100(-), and desmin(-). The Ki-67 level was<1%. The anterior wall tumors showed similar findings, but some showed smooth muscle differentiation. From the results, a diagnosis of simultaneous multiple gastric GIST(low risk)was made.
