目的 观察残胃粘膜病理形态特点 ,总结胆汁返流对残胃粘膜的影响。方法 应用常规石蜡切片 2张 ,分别染HE、亚甲兰幽门螺杆菌染色。对胃粘膜手术前后的病理变化进行总结 ,并根据悉尼胃炎新分类及DIXON病理形态积分方法对 5 6例残胃粘膜炎进行病理诊断。结果 术后胃癌复发 7例 ,发生率 12 .5 % ,其中 3例病程在 10年以上 ,4例的病程在 2个月～ 10月之间。因良性病变而手术的病例 ,无 1例癌变 ,因胃癌和胃溃疡手术的病例 ,胆汁返流性胃炎的发生率均高于其它各组 (P <0 .0 1)。结论 残胃癌的发生与手术方式无关 ,残胃癌的发生有待进一步研究。DIXON的积分对病理诊断胆汁返流性胃炎的诊断是可行的。
Objective To observe the pathological features of gastric mucosa and summarize the influence of bile reflux on gastric mucosa. Methods Two paraffin sections were stained with HE and methylene blue H. pylori respectively. The pathological changes of gastric mucosal before and after surgery were summarized, and according to the new classification of Sydney gastritis and DIXON pathological shape integration method of pathological diagnosis of 56 cases of gastric mucositis. Results Recurrence of gastric cancer in 7 cases, the incidence rate of 12.5%, of which 3 cases over 10 years in duration, 4 cases of course of 2 months to 10 months. There were no cases of cancer due to benign lesions. The incidence of gastric bile reflux gastritis was higher than that of other groups due to the cases of gastric cancer and gastric ulcer (P <0.01). Conclusion The occurrence of residual gastric cancer has nothing to do with the surgical approach, the occurrence of residual gastric cancer needs further study. DIXON integral pathological diagnosis of bile reflux gastritis diagnosis is feasible.
