Abstract
Objective: To determine the risk factors which influence the recurrence of endometriomas after laparotomy or laparoscopic surgery.
Design: Between 2000 and 2007, 98 patients who had endometrial cysts were treated by laparotomy or laparoscopic surgery at the Osaka Rosai Hospital. The surgical procedures consisted of cystectomy or an adnexectomy. Sixty-three patients underwent a cystectomy and 35 patients underwent an adnexectomy. The patients who were followed for at least 6 months were eligible for inclusion. The definition of a recurrence was based on the detection of a diffuse, hypoechoic area, the long axis of which was at least 3 cm on transvaginal ultrasonogram. Using the Cox regression test, we analyzed each patient's background variables, which included age, cyst size, BMI, and the revised American Society of Reproductive Medicine score (r-ASRM score) .
Result: The mean postoperative observation period was 31 months. Among the patients who underwent cystectomy, 11 (17.4%) of 63 patients had a recurrence. The cumulative recurrence rate per patient was 22.6% over 60 months. Among the prognostic factors, age, cyst size, and BMI had a negative correlation, whilc r-ASRM score had a positive correlation with cyst recurrence.
Conclusion: Among prognostic factors, the r-ASRM score was associated with a higher recurrence of endometriomas.
