Combining myoma coagulation with endometrial ablation/resection reduces subsequent surgery rates

This study compares results of endometrial ablation alone and in combination with myoma coagulation. Subsequent surgery rates were 38% for ablation alone and 12% for combined therapy.

The purpose of this study was to compare hysterectomy rates following various surgical procedures to treat profuse uterine bleeding as well as myomatous uteri.

This is a descriptive study of women who underwent endometrial ablation alone, endometrial ablation with myoma coagulation, or endometrial resection with myoma coagulation to treat profuse uterine bleeding as well as myomatous uterus. From 1986 to 1995, the author performed 52 endometrial ablation procedures; 88 myoma coagulation and endometrial ablation procedures; and 28 myoma coagulations with resection of submucous myomas in patients who were subsequently available for follow-up. Patients were followed up for up to ten years.

Of the patients undergoing ablation alone, 20 (38%) of 52 required a second surgery for continued symptoms during a mean follow-up of 47 months. Five of these patients (9.6%) underwent hysterectomy. Of the patients who underwent endometrial ablation plus myoma coagulation (myolysis), 11 (12.5%) of 88 required a repeat surgical procedure during a mean follow-up of 25 months. Five of these patients (5.7%) underwent hysterectomy. Volumetric measurements revealed an average reduction in fibroid volume of 54.5% in this patient group following treatment with a gonadotropin-releasing hormone (GnRH) agonist and combined myoma coagulation and endometrial ablation surgery. Of the 28 patients who underwent myoma coagulation plus resection, five (18%) required a repeat procedure. Of these five, one (4%) required hysterectomy. Fibroid volume in this group was reduced by a mean of 72.6% following administration of a GnRH agonist and combined laparoscopic and hysteroscopic surgery as described. The rate of reoperation was significantly lower among patients receiving endometrial ablation with myoma lysis with or without resection compared with those undergoing endometrial ablation alone (P<0.01).

Myoma coagulation (myolysis), when combined with endometrial ablation among women with symptomatic fibroids and bleeding, reduces all subsequent surgery rates compared with endometrial ablation alone. Myolysis with endometrial resection also results in a reduced need for hysterectomy.
