Despite technical advances, the incidence of anastomotic leaks in elective colorectal surgery remains around 14%. Recent studies suggest that the use of low-energy lasers may enhance wound healing in different tissues in a selective, nondestructive manner. Based on these findings we have attempted to provide experimental background on the histological effects of He:Ne laser during the early stages of healing in 70 colonic anastomoses performed on rats. The irradiation of the anastomoses by two doses of 3.6 J/cm2 produces an increase in the populations of round cells and fibroblasts of the scar tissue, an increase in new vessel formation, and a significant improvement in epithelialization. This suggests that the irradiation of colonic wounds with He:Ne lasers can result in an enhancement of healing.
尽管技术有所进步，但择期结直肠手术中吻合口漏的发生率仍约为14%。最近的研究表明，使用低能量激光可能以一种选择性、非破坏性的方式促进不同组织的伤口愈合。基于这些发现，我们试图为70例大鼠结肠吻合口愈合早期氦氖激光的组织学效应提供实验依据。用两剂3.6 J/cm²对吻合口进行照射，可使瘢痕组织中的圆形细胞和成纤维细胞数量增加，新血管形成增加，上皮化显著改善。这表明用氦氖激光照射结肠伤口可促进愈合。
