Hysteroscopic endometrial ablation was introduced in the 1980's as an alternative to hysterectomy in women who failed medical management. Global endometrial ablation was introduced in the 1990's as an easier, safe, and equally effective alternative to hysteroscopic ablation. Several devices have been introduced, some of which are still undergoing feasibility studies or clinical trials. These devices include: three hot water intrauterine balloons, two intrauterine free saline solutions, a multielectrode electrocoagulating balloon, a 3-D bipolar electrocoagulation probe, a microwave, a diode fibre laser, and at least three cryoprobes. These devices require less operator skill and no irrigant or distending solutions. All require either heat or cold to destroy the endometrium. Although all devices are promising and have produced impressive preliminary results, the long-term efficacy, complication rates, and cost effectiveness have not been established. This review describes all devices as they appeared chronologically and presents only peer-reviewed data.
