Tracheal resection is the preferred treatment for primary tracheal tumors. Anastomotic tension can be a problem, even when various tension-relieving release maneuvers are employed. Excessive tension can cause anastomotic sutures to pull through the tracheal tissue, with resultant early tracheal anastomotic dehiscence. To test the hypothesis that interrupted horizontal mattress sutures would withstand the forces of tension better than interrupted simple sutures, an experimental study of rat tracheal anastomoses was done.
Twenty rats were killed and their tracheas excised. The tracheas were divided in the mid portion and end to end anastomoses were done using interrupted 7-0 polypropylene sutures. Ten tracheas had anastomoses done with interrupted simple sutures, and 10 had interrupted horizontal mattress suturing.
Anastomotic breaking strength was 2.30 +/- 0.57 N for the interrupted simple sutured anastomoses and 2.15 +/- 0.48 N for the interrupted horizontal mattress group (P = 0.54). The difference was not significant.
In this animal study, interrupted simple and horizontal mattress suturing withstood the disruptive forces of anastomotic tension equally well.
气管切除术是原发性气管肿瘤的首选治疗方法。即使采用各种缓解张力的释放操作，吻合口张力仍可能是一个问题。过度的张力会导致吻合口缝线穿过气管组织，从而导致早期气管吻合口裂开。为了验证间断水平褥式缝合比间断单纯缝合更能承受张力的假设，进行了一项大鼠气管吻合的实验研究。
处死20只大鼠并切除其气管。将气管在中部切断，然后用间断7-0聚丙烯缝线进行端端吻合。10个气管采用间断单纯缝合进行吻合，10个采用间断水平褥式缝合。
间断单纯缝合吻合口的断裂强度为2.30±0.57 N，间断水平褥式缝合组为2.15±0.48 N（P = 0.54）。差异无统计学意义。
在本动物研究中，间断单纯缝合和水平褥式缝合在承受吻合口张力的破坏力方面同样有效。
