[Linear salpingotomy in the treatment of unruptured tubal pregnancy. Animal experiment study, comparison of 3 laser systems (CO2, Nd:YAG contact, argon)].

The efficacy of three different laser systems for linear salpingotomy was tested in an animal model. For that purpose, the uterus horns of 22 white New Zealand rabbits were incised with the CO2-Laser, the Nd: YAG contact laser and the argon laser using the "bare fiber" technique. The length of uterotomy was between twice and three times of the diameter of the uterine horn. Secondary healing of the incision site was investigated macroscopically (patency, fistulas, formation of adhesions) and microscopically (quantity and quality of the scars) six weeks after the operation. Despite the different primary tissue effect of the laser systems we did not find any significant difference in our postoperative controls.
