Abstract

Intragastric bacterial growth and nitrite and nitrosamine formation were investigated in animal experiments after different surgical procedures of ulcer management with regard to carcinogenesis in the operated stomach. The operative procedures resulted in an alteration in the gastric flora with an increase and predominance of nitrate-reducing bacteria. There was an increase in the intragastric nitrite and nitrosamine concentration corresponding to the increase in nitrate-reducing bacteria. All three parameters showed the greatest increase after gastric resection, whereas there were no significant differences after vagotomy with pyloroplasty, compared with a control group. These findings in animal experiments are of etiopathological relevance to the known danger of cancer in the resected human stomach and should be taken into consideration when choosing a procedure for surgical ulcer therapy.

摘要

在动物实验中,针对溃疡治疗的不同外科手术方式对手术胃部癌变的影响,研究了胃内细菌生长以及亚硝酸盐和亚硝胺的形成。手术操作导致胃内菌群发生改变,硝酸盐还原菌增加并占主导地位。胃内亚硝酸盐和亚硝胺浓度随着硝酸盐还原菌的增加而升高。这三个参数在胃切除术后增加最为显著,而与对照组相比,迷走神经切断术加幽门成形术后无显著差异。动物实验中的这些发现与人类胃切除术后已知的癌症风险具有病因学相关性,在选择手术治疗溃疡的方式时应予以考虑。
