Bipolar electrocoagulation versus suture of solitary ovary after laparoscopic excision of ovarian endometriomas.
OBJECTIVE
To compare the functional ovarian damage associated with the use of bipolar coagulation versus ovarian suture after laparoscopic excision of ovarian endometriomas in patients with a solitary ovary.


METHODS
Retrospective study (Canadian Task Force classification II-3).


METHODS
Tertiary care center.


METHODS
Forty-seven consecutive women with a single ovary and regular menses who underwent laparoscopic stripping of one or more ovarian endometriomas between June 1996 and June 2001. Intervention. Twenty-one patients had bipolar electrocoagulation (group A), while 26 had suturing of the ovary (group B). Plasma follicle-stimulating hormone (FSH) and estradiol levels were determined before surgery and re-evaluated at 3-, 6-, and 12-month follow-up.


RESULTS
At 12-month follow-up, six patients (29%) in group A had oligo-amenorrhea versus three patients (12%) in group B (p = .14). Follicle-stimulating hormone levels between 10 and 20 mlU/mL were found in five patients (24%) in group A and in three patients (12%) in group B, whereas FSH levels above 20 mlU/mL were found in three patients (14%) in group A and in no patient in group B. Eight patients (38%) in group A had FSH levels greater than 10 mlU/mL versus three patients (12%) in group B (p = .042). Overall, repeated analysis of variance showed a marginally significant difference (p = .06) in FSH values between the two groups.


CONCLUSIONS
Our results suggest that bipolar electrocoagulation of the ovarian parenchyma after laparoscopic stripping of an endometriotic ovarian cyst adversely affects ovarian function.
