What is the impact on sexual function of laparoscopic treatment and subsequent combined oral contraceptive therapy in women with deep infiltrating endometriosis?

Introduction: Deep infiltrating endometriosis (DIE) is a form of endometriosis in which the lesion penetrates for more than 5 mm under the peritoneal surface. It is a chronic disease which can impair women's sexual function. There is a growing body of evidence supporting combined surgical/medical treatment in the management of DIE.

Aims: The aims of this article are to evaluate the impact of the laparoscopic full excision of endometriosis and postoperative combined oral contraceptives (COC) administration on sexual function in patients with DIE and to compare sexual function outcomes of women submitted to intestinal resection and nodule excision.

Methods: It is a prospective cohort study in a tertiary care university hospital on 106 sexually active women, with histologically confirmed DIE, managed by laparoscopy and subsequent COC therapy for 6 months. Patients filled preoperatively and 6-month postoperatively a quality of sexual life questionnaire, the Sexual Health Outcomes in Women Questionnaire (SHOW-Q) and they ranked their symptom intensity using a 10-point visual analogue scale (VAS).

Main outcome measures: Sexual function was measured through the SHOW-Q scores and pain symptoms through VAS scores. Intraoperative details, type of intervention and perioperative complications were noted.

Results: Six months after surgery and postoperative COC treatment, a significant improvement was observed in the SHOW-Q domains of pelvic problem interference, sexual satisfaction and desire (P<0.05). Laparoscopic management of DIE did not change significantly the orgasm area of the sexual functioning (P=0.7). No significant difference was found in SHOW-Q scores between patients submitted to intestinal resection and patients submitted to intestinal nodule excision (P>0.05).

Conclusions: Sexual desire, satisfaction with sex and pelvic problem interference with intercourse are significantly improved after 6 months from laparoscopic excision of DIE combined with postoperative COC therapy. No difference in sexual outcomes was detected between patients submitted to intestinal resection and nodule excision.
