[Therapy of recurrent menorrhagia--Cavaterm balloon coagulation versus roller-ball endometrium coagulation--a prospective randomized comparative study].

In a prospective study 20 patients suffering from recurrent, therapy-refractory menorrhagias were pre-treated for endometrial ablation after exclusion of intrauterine abnormalities and histological pathology. Two injections of GnRH-analogues (3.75 mg leuprorelinacetate depot, Enantone Gyn, Takeda Pharma GmbH Aachen, Germany). Two weeks after the last injection a hysteroscopic surgery by roller-ball-techniques was performed in 10 patients and a balloon-thermocoagulation by Cavaterm-technique (Wallsten Medical, Morges, Schweiz) was performed in 10 patients. Both patients groups were comparable according to age and anamnesis. In a follow-up of 9 to 15 months we found about identical results. All 20 patients were satisfied with the treatment. The Cavaterm-coagulation is in comparison to the operative hysteroscopy a simple method for endometrial coagulation, and can also be used by an hysteroscopically inexperienced gynaecologists with simple technical equipment. In strict indication the Cavaterm-coagulation is a simple method of endometrial ablation in many patients.
