Effects of a low-power He-Ne laser on the healing of experimental colon anastomoses: our experience
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 effects of a He-Ne laser during the early stages of healing in 155 colonic anastomoses performed on rats. The irradiation (external or endoscopical) ofthe anastomoses by repeated doses below 4 J/cm 2 suggest (1) the laser-induced enhancement of anastomotic healing can be obtained in both healthy colons or in situations in which anastomotic breakdown is mor…
Histological effects of He-Ne laser on the healing of experimental colon anastomoses in the rat
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 anastornoses performed on rats, The irradiation of the anastomoses by two doses of 3.6 J/cm 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.
