To study and investigate the feasibility of biofragmentable anastomosis ring (BAR) for gastrointestinal (GI) tract reconstruction, we performed gastroenterostomy in 34 dogs. BAR anastomoses were performed with proper outer diameter and gape size in small bowel in 8 cases, in large bowel in 11 cases, in esophagus in 12 cases, in esophago-intestinal in 2 cases, in gastrojejunum in 1 cases. The postoperative serial X-ray examinations showed that BAR maintained good integration two weeks postoperation. The ring disintegrated into several small fragments that passed out of the body in feces from the 14th postoperative day after surgery. All of the dogs were killed on the 28th operative day and autopsied. The anastomosis site had smooth serosa and scar membrane in gross and were substituted by regenerative fibrous tissue. The specimen barim-air double contrast X-ray revealed that GI tract was coherent without leakage and stenosis. Therefor, the authors recognized that BAR can be recommended as a safe technique in GI operation.
为研究和探讨生物可降解吻合环（BAR）用于胃肠道（GI）重建的可行性，我们对34只犬进行了胃肠吻合术。8例在小肠、11例在大肠、12例在食管、2例在食管-肠道、1例在胃空肠进行了外径和间隙大小合适的BAR吻合。术后系列X线检查显示，术后两周BAR保持良好的整合状态。术后第14天起，吻合环分解为几个小碎片并随粪便排出体外。所有犬在手术第28天处死并进行尸检。吻合部位肉眼可见浆膜光滑，有瘢痕膜，被再生纤维组织替代。标本钡气双重造影X线显示胃肠道连贯，无渗漏和狭窄。因此，作者认为BAR可作为GI手术中的一种安全技术推荐使用。
