A study from Beijing compared three treatment arms to find the most effective treatment for endometrial ovarian cysts.  152 patients with endometrial ovarian cysts were divided into three groups: an integrated laparoscopy and Chinese herbal medicine (combination group), a Chinese herbal medicine group, and a Danazol group.  The clinical efficacy, side-effects and reproductive hormones were compared.  The shrinking rate and disappearance rate of the cysts were highest in the combination group as was the pregnancy rate.  Few side effects were noticed in the combination and Chinese herbal medicine group.  The authors conclude that combining laparoscopy with Chinese herbal medicine is an effective treatment for endometrial ovarian cysts with minimal side effects and a maximal preservation of the reproductive function.
