目的　分析和总结残胃癌的外科诊断和治疗情况。方法　回顾分析了 2 8例残胃癌发病率、临床表现及治疗情况。结果　首次胃切除以胃溃疡为主 ,占 6 4 3%。首次手术B Ⅱ式 2 2例 ,占 84 6 % ,确诊残胃癌距首次手术时间平均为 2 8 3年。残胃癌发生在吻合口占 5 0 % ,残胃小弯侧 4 2 9% ,贲门部 7 1%。结论　胃良性病行手术治疗时以B Ⅰ式为首选 ;定期胃镜检查残胃癌高危人群 ,早期诊断、早期治疗是提高残胃癌预后的关键。 Objective To analyze and summarize the surgical diagnosis and treatment of residual gastric cancer. Methods Retrospective analysis of 28 cases of gastric cancer incidence, clinical manifestations and treatment. Results The first gastrectomy mainly consisted of gastric ulcer, accounting for 64.3%. The first operation of B Ⅱ type 2 2 cases, accounting for 84 6%, diagnosed residual gastric cancer from the time of the first operation an average of 283 years. Gastric stump cancer occurred in 50% of the anastomosis, 429% of the lesser curvature side of the stomach, and 71% of the cardia. Conclusions Gastric benign disease is the first choice for surgical treatment with B Ⅰ. Regular gastroscopic examination of gastric cancer patients at high risk of gastric cancer, early diagnosis and early treatment is the key to improve the prognosis of gastric cancer.
