Abstract: Objective : To investigate the early diagnosis and surgical treatment of remnant gastric cancer (RGC) developed after suntotal gastrectomy. Methods : Clinicopathologic data of 26 cases of gastric RGC was studied retrospectively, and the diagnostic value of the gastroscopy and barium meal was compared. The effect of different operations on the prognosis of RGC was observed. Results : The diagnostic rate of gastroscopy and of barium meal was 80.8% and 50.0%, respectively. A ll the 20 cases who underwent radical remant gastrectomy survived postoperatively for more than 3 years. Five of the 7 cases who underwent palliative remnant gastrectomy survived for 2 years and 2 were alive in 1 year and a half postoperatively. In 4 cases of gastrojejunostomy, 3 died within half a year, 1 died in 1 year postoperatively. Conclusion : The diagnostic value of gastroscopy is superior to that of barium meal. The patients diagnosed earlier and treated by radical remnant gastrectomy have a better prognosis.
