This study analyzed 98 patients treated for endometriomas and found that higher r-ASRM scores correlate with increased recurrence, while age, cyst size, and BMI correlate negatively.

This study evaluated recurrence risk factors for endometriomas after laparotomy or laparoscopic surgery in 98 patients treated with cystectomy or adnexectomy between 2000 and 2007. Eligible patients had at least 6 months of follow-up, and recurrence was defined using transvaginal ultrasonography as a diffuse hypoechoic area with a long axis of at least 3 cm. After a mean postoperative observation of 31 months, 17.4% of 63 cystectomy patients had recurrence, with a cumulative recurrence rate of 22.6% over 60 months. Cox regression found age, cyst size, and BMI negatively correlated with recurrence, while the revised ASRM (r-ASRM) score positively correlated; the paper’s results are limited by inclusion criteria focused on those followed ≥6 months. This paper is centrally about endometriosis — it analyzes recurrence of endometriomas after surgical intervention and identifies prognostic associations, including r-ASRM score.

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.
