Hysteroscopic management of uterine bleeding.

Hysteroscopy provides a means of accurately diagnosing and treating most forms of abnormal uterine bleeding. Submucous myomas and endometrial polyps may be easily removed with the resectoscope. If the myomas are large, pre-treatment with GnRH agonists will shrink the tumours, and facilitate hysteroscopic removal. One third of patients undergoing hysteroscopic myomectomy will have recurrent symptoms that require intervention. In the absence of malignancy, and in patients not desiring fertility, persistent dysfunctional uterine bleeding may be treated by endometrial ablation. These patients should be pre-treated with either danazol or GnRH agonists. Success with these techniques approaches 85%, but information about the long-term outcome for the majority of the reported cases is not available. Complications include uterine perforation and damage of intra-abdominal structures, fluid and electrolyte imbalance including pulmonary oedema, and anaphylactic reactions to certain distention media (32% dextran 70). These procedures provide the gynaecologist with an effective means of treating abnormal uterine bleeding without the attendant morbidity of a hysterectomy.
