This retrospective study compared ovarian reserve effects after laparoscopic excision of unilateral ovarian endometrioma using either bipolar electrocoagulation (26 women) or suturing of the ovarian parenchyma (22 women) for hemostasis. Serum anti-Mullerian hormone (AMH), FSH, and estradiol were measured preoperatively and 1 month postoperatively, and antral follicle count (AFC) was assessed from the operated and contralateral intact ovary. AMH levels decreased significantly 1 month after surgery in both groups, while FSH and estradiol did not differ significantly pre- versus postoperatively in either group; in the suture group, AFC in the operated ovary was significantly reduced compared with the contralateral ovary. The authors’ main limitation is the short follow-up window (only 1 month) and the retrospective nonrandomized design, which may affect interpretability. This paper is centrally about endometriosis—specifically how laparoscopic excision of ovarian endometrioma and hemostatic technique (electrocoagulation vs suturing) affect short-term ovarian reserve markers.

Abstract

Objective: To assess whether coagulation or suture for hemostasis during laparoscopic excision of unilateral endometrioma affects short-term ovarian reserve. Methods: From April 2008 to March 2011, 48 women underwent laparoscopic excision of endometrioma. In 26 patients, bipolar electrocoagulation was used for hemostasis, while in 22, the ovary was sutured. We reviewed these cases retrospectively. Age, BMI, menstrual cycle day, tumor size, and American Society for Reproductive Medicine (rASRM) score at laparoscopy were observed as baseline clinical characteristics for each patient. Serum anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol levels were measured preoperatively and 1 month postoperatively and compared in both groups. The antral follicle count from the operated ovary and the intact ovary in each group were also analyzed 1 month postoperatively.Results: Age, BMI, and menstrual cycle day were similar in the 2 groups. There was no significant difference between the 2 groups in rASRM score or size of endometriomas. No significant differences in preoperative and post-operative serum FSH and Estradiol levels were found in either group. Serum AMH levels were significantly decreased postoperatively in both groups. In the suture group, the mean number of AFC was significantly reduced in the operated ovary compared with the contralateral intact ovary.Conclusions: Laparoscopic excision of unilateral endometrioma appears to adversely affect AMH hormonal values 1 month after operation. Our results suggest that suturing of the ovarian parenchyma after laparoscopic excision of endometrioma adversely affects ovarian reserve in the short-term. We suggest that these findings might be of particular interest when treating women with risk factors of postoperative ovarian reserve impairment.

Abstract

Objective: To assess whether coagulation or suture for hemostasis during laparoscopic excision of unilateral endometrioma affects short-term ovarian reserve.

Methods

From April 2008 to March 2011, 48 women underwent laparoscopic excision of endometrioma. In 26 patients, bipolar electrocoagulation was used for hemostasis, while in 22, the ovary was sutured. We reviewed these cases retrospectively. Age, BMI, menstrual cycle day, tumor size, and American Society for Reproductive Medicine (rASRM) score at laparoscopy were observed as baseline clinical characteristics for each patient. Serum anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol levels were measured preoperatively and 1 month postoperatively and compared in both groups. The antral follicle count from the operated ovary and the intact ovary in each group were also analyzed 1 month postoperatively.

Results

Age, BMI, and menstrual cycle day were similar in the 2 groups. There was no significant difference between the 2 groups in rASRM score or size of endometriomas. No significant differences in preoperative and post-operative serum FSH and Estradiol levels were found in either group. Serum AMH levels were significantly decreased postoperatively in both groups. In the suture group, the mean number of AFC was significantly reduced in the operated ovary compared with the contralateral intact ovary.

Conclusions

Laparoscopic excision of unilateral endometrioma appears to adversely affect AMH hormonal values 1 month after operation. Our results suggest that suturing of the ovarian parenchyma after laparoscopic excision of endometrioma adversely affects ovarian reserve in the short-term. We suggest that these findings might be of particular interest when treating women with risk factors of postoperative ovarian reserve impairment.

Results

Age, BMI, and menstrual cycle day were similar in the 2 groups. There was no significant difference between the 2 groups in rASRM score or size of endometriomas. No significant differences in preoperative and post-operative serum FSH and Estradiol levels were found in either group. Serum AMH levels were significantly decreased postoperatively in both groups. In the suture group, the mean number of AFC was significantly reduced in the operated ovary compared with the contralateral intact ovary.

Laparoscopic excision of unilateral endometrioma appears to adversely affect AMH hormonal values 1 month after operation. Our results suggest that suturing of the ovarian parenchyma after laparoscopic excision of endometrioma adversely affects ovarian reserve in the short-term.
