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。
The authors used the biodegradable stapling ring (BAR) for animal gastrointestinal anastomosis experiments to study and explore the value of BAR in the digestive tract reconstruction. 34 Beagle dogs were selected as experimental subjects. Eighty cases of small bowel anastomosis, 11 cases of large intestine anastomosis, 12 cases of esophagogastric anastomosis, 2 cases of esophageal and jejunostomy, example. Postoperative abdominal plain film examination found BAR maintained good integrity within 2 weeks, gastrointestinal patency, no obstruction, BAR gradually lost the integrity after 2 weeks, hydrolyzed into small fragments excreted. All experimental dogs were sacrificed on the 28th day after operation and observed anatomically. The naked eye observed anastomosis serosal surface smooth, mucosal surface scar formation, microscopic examination see anastomosis was replaced by fibrous tissue regeneration. Gastrointestinal double contrast barium see gastrointestinal patency, no stenosis and fistula. The authors believe that the experiment proved that BAR can be safely used for digestive tract reconstruction.
