Comparison between Injection of Diluted Vasopressin and Saline Only in Laparoscopic Excision of Ovarian Endometrioma

Background: The formation of tissue that resembles endometrium outside of the uterus is a hallmark of the chronic inflammatory disease known as endometriosis. Ovarian endometriosis typically affects women. 19%–28% of endometriosis patients have bilateral ovarian endometriomas. Laparoscopic cyst excision for endometriotic ovarian cysts improves fertility and reduces recurrence. The vasopressin injection approach was developed to reduce endometrioma recurrence and preserve ovarian reserve after laparoscopic cystectomy.
