[Animal experiments to study use of CO2 laser for salpingolysis (author's transl)].

The animal experiments reported in this paper were applied to the uterine cornu of rabbit for the purpose of finding out whether CO2 laser could be used for successful salpingolysis. -Continuous intraluminal pH measurement was undertaken along with laser irradiation. Second-look operations were performed and accompanied by repeated pH measurement and histological tissue tests, after four weeks had elapsed from irradiation, in an attempt to verify radiation effects. Short-time pH decline was observed. Neither any adhesion nor induration was found to exist any longer in the irradiated area, four weeks after surgery. Low-residue healing of the uterine cornua, with no involvement of internal functional layers, was histologically confirmed. - The above experiments are likely to show that laser radiation has been of little functional and morphological impact upon the uterine cornu of rabbit. The authors, therefore, support the idea of using CO2 laser in salpingolysis to cut adhesions close to the fallopian tube and to stop bleeding at the same time.
