Objective:
To determine the difference between two laparoscopic methods for the management of endometriomas with regard to recurrence of signs and symptoms and pregnancy rate.
Design:
Prospective, randomized clinical trial.
Setting:
Infertility and gynecologic endoscopy units of two medical university hospitals.
Patient(S):
One hundred patients with endometriomas who had either infertility or pelvic pain.
Intervention(S):
Patients were randomly divided into two groups; one group underwent cystectomy (group 1), and fenestration and coagulation were performed for the other (group 2).
Main Outcome Measure(S):
A comparison of recurrence of signs and symptoms of endometriomas and pregnancy rates in two groups.
Result(S):
Fifty-two patients were studied in group 1 and 48 in group 2. The recurrence of symptoms, such as pelvic pain and dysmenorrhea, was 15.8% in group 1 and 56.7% in group 2 after 2 years. The rate of reoperation was 5.8% in group 1 and 22.9% in group 2 and these differences were statistically significant. The cumulative pregnancy rate was significantly higher in group 1 (59.4%) than in group 2 (23.3%) at 1-year follow-up.
Conclusion(S):
Laparoscopic cystectomy of endometriomas is a better choice than fenestration and coagulation because the former technique leads to a lower recurrence of signs and symptoms and a lower rate of reoperation and a higher cumulative pregnancy rate than the latter.
