摘要
作者通过生物分解性吻合环（ＢＡＲ）用于动物胃肠道吻合的实验，研究和探讨ＢＡＲ在消化管重建术中的应用价值。以３４只Ｂｅａｇｌｅ犬为实验对象，选择适当外径和环间距的ＢＡＲ，行小肠吻合术８例、大肠吻合术１１例、食管吻合术１２例、食管空肠吻合术２例、胃空肠吻合术１例。术后腹部平片检查发现，２周内ＢＡＲ保持良好的完整性，胃肠道通畅、无梗阻，２周后ＢＡＲ逐渐失去完整性，水解成小碎片排出体外。术后第２８天处死全部实验犬，进行解剖观察。肉眼观察见吻合处浆膜面光滑，粘膜面形成瘢痕，光镜检查见吻合口被再生的纤维组织取代。标本气钡双重造影见胃肠道通畅，无狭窄及瘘道。作者认为，实验证明ＢＡＲ可安全用于消化管重建术。
