[Intraluminal Type Gastrointestinal Stromal Tumor Resected by Single-Incision Percutaneous Endoscopic Intragastric...

We report a patient with gastric gastrointestinal stromal tumor (GIST) who underwent single-incision percutaneous endoscopic intragastric surgery. The patient was a 70-year-old man. Esophagogastroduodenoscopy and abdominal computed tomography revealed the presence of an intraluminal type gastric submucosal tumor, 4 cm in diameter, in the posterior wall of the gastric body. Laparoscopic partial gastrectomy was performed via a single incision made in the epigastric region. The postoperative course was uneventful. The pathological diagnosis was a low-risk GIST. This method is easy and safe to perform; therefore, we consider it to be an important option for the treatment of intraluminal type gastric GIST.
