目的对４２６例残胃进行纤维胃镜随访观察。方法采用日本Ｏｌｙｍｐｕｓ各型纤维胃镜进行检查，对诊断结果进行分析。结果发现残胃病变依次为炎症４２２例（９９．１％）、溃疡９５例（２３．３％）、癌６６例（１５．５％）、息肉１１例（２．６％）。（１）残胃发生胆汁返流者占６１．７％，其中Ｂ－Ⅱ式较Ｂ－Ⅰ式易发生胆汁返流（Ｐ＜０．０５）。（２）良性病变较恶性病变术后易发生溃疡（Ｐ＜０．０５），溃疡易发生在吻合口，Ｂ－Ⅱ式较Ｂ－Ⅰ式术后溃疡发生率高（Ｐ＜０．０１）。（３）残胃复发癌占癌总数的８９．４％，与我区胃癌高发、就诊晚有关。（４）残胃息肉中腺瘤息肉占２７．３％。结论建议残胃胃镜普查。残胃癌的发生与随访年限、术式有关，但与术前是良或恶性病变无关（Ｐ＞０．０５）。
Objective To observe the gastric remnant gastroscopy of 426 cases of gastric residual. Methods Various types of gastroscope were used in Olympus in Japan to analyze the diagnosis results. The results showed that there were 422 cases (99.1%) of inflammation, 95 cases (23.3%) of ulcer, 66 cases of cancer (15.5%) and 11 cases of polyps (2.6%). (1) The incidence of bile reflux in gastric remnant accounted for 61.7%, of which B-Ⅱ was more likely to have bile reflux (P <0.05) than B-Ⅰ. (2) The incidence of ulcer was more likely to occur in benign lesion than in malignant lesion (P <0.05), ulcer easily occurred in anastomosis, and the incidence of ulcer in B-Ⅱ was higher than that in B-Ⅰ (P <0.01) . (3) Residual gastric cancer recurrence accounted for 89.4% of the total number of cancer, with high incidence of gastric cancer in our area, late treatment. (4) residual gastric polyps adenoma polyps accounted for 27.3%. Conclusion Suggest residual gastric gasoscopy. The incidence of residual gastric cancer was related to the follow-up period and surgical procedure, but not to the benign or malignant lesions preoperatively (P> 0.05).
