[A Case of Gastric Remnant Cancer after Proximal Gastrectomy with Jejunum Pouch Interposing Reconstruction].

A 83-year-old man was diagnosed an earlygastric remnant cancer on the site of jejuno-gastrostomyafter proximal gastrectomywith jejunum interposing reconstruction 23 years ago. A total gastrectomywas performed due to the difficultyof endoscopic submucosal resection. The surgical operation took 200 minutes and the blood loss was 180 mL. Histologically, tumor size was 28×22mm invading to submucosal layer with a lymph node metastasis. To reduce the risk of surgical operation for gastric remnant cancer of aged patients, a simple reconstruction method is important for proximal gastrectomy, like a esophagogastrostomyplacing a gastric tube in the mediastinum.
