腹腔鏡下手術で治療した出血性胃inflammatory fibroid polypの1例

抄録

Inflammatory fibroid polyp (IFP) is a rare disease characterized by spindle-shaped tumor cells with eosinophilic infiltration. A 70-year-old woman was hospitalized with hematemesis in March 2015. Upper gastrointestinal endoscopy revealed blood coagulum in the stomach and a submucosal tumor-like lesion (2cm in diameter) at the posterior wall of the antrum. Because the blood clot-containing ulcer was observed on the tumor surface, we performed hemostasis under endoscopy. Distal gastrectomy was performed under laparoscopy with laparoscopic reconstruction in April 2015. Because microscopic examination revealed spindle-shaped tumor cells with eosinophilic infiltration in the sample and immunohistological staining showed the tumor cells to be negative for KIT, IFP was diagnosed. We performed minimally invasive surgery under laparoscopy with laparoscopic reconstruction for gastric IFP.
