目的探讨术中用充气法检查已完成的吻合口缝合效果。方法术中吻合完成以后,以纱条对吻合上下进行轻柔阻断,经胃管注入空气检查吻合口区域。有气泡自液面溢出则标明吻合口有物理破口,重新吻合。随机抽查100例作为试验组,其结果与不作充气检查的102例(对照组)比较。结果试验组术后发生吻合口瘘1例(1.0%),明显少于对照组的8例(7.8%)(P<0.05)。结论用充气法能及时发现术中吻合失败的病例,有效降低术后吻合口瘘的发生率。 Objective To investigate the effect of anastomosis sutured by the inflation method in operation. Methods After the anastomosis was completed in the operation, the sliver was gently closed to the anastomosis, and the air was injected into the anastomotic area through the gastric tube. A bubble overflow from the surface of the fluid is marked with an agreement to have a physical break, re-match. A random sample of 100 cases was used as the test group, and the results were compared with 102 cases (control group) that were not inflated. Results One case (1.0%) had anastomotic fistula after operation, which was significantly less than that of the control group (7.8%) (P <0.05). Conclusion Inflatable method can promptly find cases of intraoperative anastomosis failed to reduce the incidence of postoperative anastomotic leakage.
