[The biological effects of the CO2 laser studied in experimental intestinal resections].
An histological and E.M. study has been performed on rat's intestinal tract resection to evaluate CO2 laser effects. Necrotic effect of laser is evident up to 120 micron. While the intestinal tissue results normal at 480 micron from resection line. Muscular and fibrous components appear more resistant to damage while E.M. presents a new organization of its components forming a new compact and continue tissue. This new organization may be involved in the protection of the subepithelial spaces, and may have an important role in intestinal anastomosis scar process.
