Is balloon ablation as effective as endometrial electroresection in the treatment of menorrhagia?
GROUND: Hot-fluid balloon therapy is a recently introduced, relatively simple endometrial ablation procedure for menorrhagia. Because it is thought to be safer than other ablation procedures, it would be superior to other types of ablation if it is equally effective. The purpose of the present study was therefore to compare the safety and effectiveness of balloon ablation and transcervical resection of the endometrium (TCRE) for the treatment of menorrhagia. PATIENTS AND METHODS: We performed a prospective cohort study comparing TCRE and hot-fluid balloon ablation in consecutive patients suffering from menorrhagia and not responding to medical treatment. Between 1992 and 1994, all patients had TCRE, whereas from 1995 onward, all patients had balloon therapy. Outcome measures were surgical reintervention, menstrual pattern, and patient satisfaction. Assuming a 9% reintervention rate after TCRE, a series of 150 patients was required to show balloon ablation to be equally effective. RESUL
