Experience with 800 hysteroscopic endometrial ablations

Study Objective. To determine the safety and efficacy of hysteroscopic endomet Design. Retrospective record review. Setting, A credentialing program in teaching and nonteaching hospitals. Patients, Eight hundred women who underwent endometrial ablation in 54 hospitals, with indications of abnormal uterine bleeding disrupting lifestyle, postmenopausal bleeding during hormone, replacement therapy, poor surgical risk for hysterectomy, or desire to preserve the uterus. Interventions. Seventy percent of the patients were treated with danazol 100 to 600 mg/day to, 6 to 12 weeks, 8% received gonadotropin-releasing hormone analogs, 7% received progestins, and 15% were given no preoperative treatment. Under appropriate anesthesia the cervix was dilated to 10 mm and the uterine cavity was distended with 1.5% glycine solution under gravity inflow of 80 to 100 cm water and outflow suction of 80 to 100 mm Hg pressure. Electrocoagulation with or without resection was completed using 100 and 125 W respectively. Measurements and Results, At 12 months 60% of patients reported amenorrhea, 29% hypomenorrhea, 6% eumenorrhea, and 5% no change. Repeat ablation was performed in 4% of patients. An additional 2% had hysterectomy for malignancy (endometrium 2, sarcoma 1, atypical hyperplaisa 1), pelvic pain (4), fibroids (4), persistent bleeding (3), and endometritis (2). The complication rate was 3.9%: false passage (6), uterine perforation (dilator 4, resectoscope 2, Laminaria 1), fluid absorption greater than 1500 ml (8), minor bleeding (5), endomyometritis (4), and intrauterine pregnancy (1). Conclusions, Hysteroscopic endometrial ablation is a safe and effective treatment for with menometrorrhagia.
