Non–exposed endoscopic wall‐inversion surgery for pediatric gastrointestinal stromal tumor: A case report

다국어 초록 (Multilingual Abstract)

Gastrointestinal stromal tumors (GIST) in patients under 18 years of age are classified as pediatric GIST. Pediatric GIST are extremely rare, and there are no reports of laparoscopic‐endoscopic cooperative surgery for these lesions. We report the use of non‐exposed endoscopic wall‐inversion surgery as a laparoscopic‐endoscopic cooperative surgery‐related procedure for the treatment of a pediatric GIST. The case involved a 17‐year‐old male patient who presented with anemia and was found to have a bleeding gastric tumor. The tumor was resected transorally using the non‐exposed endoscopic wall‐inversion surgery technique. No gene mutation of c‐Kit or Platelet‐Derived Growth Factor Receptor α (PDGFRα) was found, and the final pathological diagnosis was epithelial‐type GIST due to a succinate dehydrogenase abnormality. Follow‐up included a CT scan every 4 months. No recurrence has occurred to date.
