Résumé
OBJECTIVE: To report 18 months follow up results of radiofrequency myolysis and analysis the factors which effect the success rate of myolysis. METHODS: 153 patients who took radiofrequency myolysis between October 2004.~June 2006 in this hospital were enrolled this retrospective study. Except 14 patients which had incomplete data, total 139 patient's charts were reviewed. Sonographic evaluations were checked after a week, 1 month, 3 months, 6 months, 12 months, and 18 months after myolysis. Questions about complications like vaginal bleeding, abdominal pain, feber and vaginal discharge were asked to patients in every visits. Volume of the myoma were checked via 3D ultrasonography. RESULTS: Reduction rate of the volume of myoma after 18 months were 73% and reoperation rate were 4.3%. Improvement rates of patients symptom were 87% (menorrhagea 95%, dysmenorrheal 75%, pelvic pain 60%) The patients who had myomas sized over 100 ml before treatments showed statistically higher rate of reoperation, and decreased rate of satisfaction. Reoperation rate and reduction rate of myoma showed no difference through pathologic diagnosis. The patients who had initial symptoms showed higher rate of satisfaction after myolysis. Total satisfaction rate were 62%, and no serious complications like bowel injury, bladder injury, sepsis and peritonitis were not reported. CONCLUSION: Satisfaction rate after radiofrequency myolysis was increased in symptomatic leiomyoma especially smaller than 6.5 cm in diameter.
