[Surgical treatment of gastric remnant-stump cancer].

The aim of this study was to evaluate the characteristics, and treatment of gastric remnant cancer based on an analysis of the surgical results of Nippon Medical School over the past 18 years. Thirty seven patients (27 males and 10 females, mean age 60 years) underwent surgery for gastric remnant cancer. Patients who had undergone gastrectomy with Billroth II anastomosis for benign disorder underwent re-gastrectomy for the cancer of gastric remnant 20 years after the first gastrectomy. While, patients who had undergone gastrectomy with Billroth I anastomosis for malignant disorder underwent re-gastrectomy within 10 years after the first gastrectomy. Early-type gastric remnant cancers were not observed in the suture line or gastric stump region, while advanced-type cancers were observed in the anastomotic region. Surgical treatment was carried out by the method of total gastrectomy with Roux-en-Y esophago-jejunal anastomosis. The 5 year survival rates were 77%for early cancer and 14%for advanced cancer. Periodic follow-up endoscopies in gastrectomized patients may be useful for the early detection of gastric remnant cancer after operations for gastric cancer.
