[Management of ovarian cysts]

Ovarian cysts occur frequently in women of reproductive age. These are usually functional cysts which resolve spontaneously and whose evolution can be followed with ultrasound. Non-functional cysts have diverse histologic origins. The most common are serous and mucinous cystadenomas which arise from the epithelial wall of the ovary, endometriomas which arise in the setting of pelvic endometriosis, and dermoid cysts which arise from the germinal cells of the ovary. Endovaginal ultrasound with Doppler enhancement is the best imaging technique to establish the nature of cysts and to distinguish cysts suspicious for malignancy which require more invasive investigation. Pelvic laparoscopy is the surgical approach of choice for the treatment of non-functional benign ovarian cysts. Conservative treatment to shell out the cyst and preserve functional ovarian tissue should be reserved for women desirous of future pregnancies. The risk of ovarian cancer remains a major preoccupation of the surgeon. Where malignancy is suspected, laparoscopy is contraindicated and a median laparotomy is appropriate for radical extirpative surgery. This article describes the diagnostic techniques which allow a laparoscopic approach to presumably benign cysts and discusses surgical techniques specifically adapted to their different histologic nature of ovarian cysts.
