Endometrial Thermal Coagulation – Degree of Uterine Fibrosis Predicts Treatment Outcome

OBJECTIVE: To study the uterine cavity after thermal endometrial destruction for the treatment of menorrhagia by means of a balloon catheter, the Cavaterm system. To relate the appearance of the uterine cavity to the outcome of the treatment. METHODS: Fifty-one of the first 60 women treated with balloon endometrial destruction were examined with hysteroscopy and saline infusion sonography 11-28 months after treatment. RESULTS: Patients with minimal or no bleeding after thermal endometrial destruction had more uterine fibrosis than patients bleeding more. CONCLUSION: The greater the degree of fibrosis of the uterine cavity after balloon endometrial destruction by thermal coagulation, the better the effect on menorrhagia.
