Abstract
Interstitial laser photocoagulation (ILP), which is a new method of low power laser destruction of tumors, has been used to treat laparoscopically 50 consecutive patients with symptomatic uterine leiomyomas which were difficult or impossible to remove via laparoscopy. The KTP/YAG laser, with wavelengths of 532 and 1064 nm respectively, was employed. Holes 2 cm apart were drilled with a 600 micrometers quartz laser fiber employing the KTP component at 8 W and subsequent coagulation of the surrounding myoma tissue was accomplished during the withdrawal of the fiber over the course of 10 - 30 s but using the YAG component at 8 W until the whole myoma had been treated. Thirty seven became symptom free and have remained so. Six were lost to follow up. Of 10 complaining of subfertility 4, in whom uterine myomas were the only etiological factor, have become pregnant. Seven patients required further treatment: Two were retreated because their myomas were excessively large and did not completely disappear with the initial ILP, 2 received further ILP because of the development of new myomas and 3 were subjected to laparoscopically assisted vaginal hysterectomy at patients' request (2 because of the development of new myomas and 1 because of the development of further endometriosis). Finally, in 7 cases, residual tumor or scar tissue was biopsied and examined for the presence of oestrogen and progesterone receptors. None was discovered and in 2 subsequent pregnancy did not cause further growth of residual myoma tissue.
