Abstract
OBJECTIVE:
To compare two second-generation endometrial ablation systems in women with dysfunctional uterine bleeding (DUB) who want conservative surgical treatment.
DESIGN:
A double-blind, randomized trial.
SETTING:
A minimal access gynecological surgery unit in northeast England.
PATIENT(S):
Fifty-seven women diagnosed with DUB were recruited, with 55 undergoing surgery and completing 12-month follow-up.
INTERVENTION(S):
Thirty-seven women underwent a NovaSure endometrial ablation, and 18 had a Cavaterm endometrial ablation. Clinical and quality of life data were collected 6 and 12 months after treatment.
MAIN OUTCOME MEASURE(S):
Amenorrhea, menstrual change, quality of life, sexual activity, patient satisfaction, and procedure acceptability.
RESULT(S):
Amenorrhea, hypomenorrhea, eumenorrhea, and menorrhagia rates for the Cavaterm and Novasure groups at 12 months were 2/18 (11%) vs. 16/37 (43%); 11/18 (61%) vs. 10/37 (27%); 5/18 (27%) vs. 6/37 (16%); and 0/18 vs. 5/37 (13%), respectively. At 12 months, 83% and 92% of women were either satisfied or very satisfied in the Cavaterm or Novasure groups, respectively. There were no major complications in either group.
CONCLUSION(S):
Both the Cavaterm and the Novasure endometrial ablation systems are effective in reducing menstrual loss in women with DUB and achieve high rates of patient satisfaction. The Novasure system achieved a statistically significantly higher rate of amenorrhea in this study.
