Prophylactic procedures associated with gynecological surgery for the management of superficial endometriosis and adhesions. Clinical practice guidelines from the French College of Gynecologists and Obstetricians (CNGOF).

Objective: To provide guidelines from the French College of Obstetricians and Gynecologists (CNGOF), based on the best currently available evidence, for the prophylactic procedures associated with gynecological surgery for benign disease such as superficial endometriosis lesions and adhesions.

Methods: The CNGOF has decided to adopt the AGREE II and GRADE systems for grading scientific evidence. Each recommendation for practice was allocated a grade that reflects the quality of evidence (QE) (clinical practice guidelines).

Results: Endometriosis and pelvic pain Superficial endometriosis can be entirely asymptomatic. Surgical treatment of asymptomatic superficial peritoneal endometriosis is not recommended in women of childbearing age for the prevention of pelvic pain, especially in case of proximity to noble organs (e.g., the ureters, rectum and sigmoid, and ovaries in nulligravida) as there is no evidence that the disease will progress to become symptomatic (low level of evidence). In case of accidental discovery of superficial endometriosis in women of childbearing age with pelvic pain, it is recommended that the lesions are excised, if surgically accessible. Removal of superficial endometriosis lesions in patients with painful symptoms improves quality of life and pain (low level of evidence). Endometriosis and infertility It appears that women with isolated superficial endometriosis diagnosed by laparoscopy with histological confirmation have a significantly higher incidence of primary infertility than patients without endometriosis. However, there is no data regarding the impact of treatment of these lesions on the fertility in these women or on the natural course of their disease (low level of evidence). It is recommended that excision is performed rather than monopolar coagulation of superficial endometriosis lesions in infertile women, as this results in a higher spontaneous pregnancy rate (low level of evidence). Adhesions and pelvic pain There is limited data in the literature regarding the benefit of performing systematic adhesiolysis during laparoscopy to prevent pelvic pain when incidental pelvic adhesions are discovered. For patients with pelvic pain, it is probably better not to perform adhesiolysis to prevent pelvic pain, although this can be decided on a case-by-case basis depending on the extent of the adhesions, the topography, and the type of surgery considered (low level of evidence). For asymptomatic patients, it is recommended not to perform adhesiolysis to prevent pelvic pain due to the lack of clear efficacy both short- or long-term and due to the increased risk of surgical injuries (low level of evidence). Adhesions and infertility There is limited data in the literature regarding the potential benefit of performing systematic adhesiolysis when there is an incidental discovery of pelvic adhesions during laparoscopy to prevent infertility. For infertile women, in the event of fortuitous discovery of adhesions at laparoscopy, it is probably better not to perform complex adhesiolysis. Only adhesiolysis of tubo-ovarian adhesions that are minimal or slight in terms of their extension and/or their nature may be useful to improve the chances of spontaneous pregnancy. However, it remains to be decided on a case-by-case basis depending on other potential causes of infertility (low level of evidence). For women without known infertility issues, it is probably better not to perform systematic adhesiolysis in order to improve their pregnancy chances, considering the balance between the unknown benefit and the risks of complications inherent to surgery (low level of evidence).

Conclusion: Further investigations are needed in order to increase the quality of management regarding associated interventions such as the treatment of superficial endometriosis or adhesions performed during a gynecologic surgical procedure and, thereby, bolster these recommendations.
