Effect of hysterectomy on pain in women with endometriosis : a population-based registry study

Objective: To assess pain symptoms before and after hysterectomy in women with endometriosis. Design: A population-based registry study. Setting: Sweden. Population: Women aged 18-45 years who underwent hysterectomy for endometriosis between 2010 and 2015. Methods: Pain symptoms before hysterectomy and 12 months after surgery were collected from the Swedish National Quality Register for Gynaecological Surgery (GynOp). Pain symptoms were also assessed by follow-up surveys after a median follow-up period of 63 months. Main outcome measures: Pelvic or lower abdominal pain after hysterectomy. Results: The study included 137 women. The proportion of women experiencing pain of any severity decreased by 28% after hysterectomy (P < 0.001). The proportion of women with severe pain symptoms decreased by 76% after hysterectomy (P < 0.001). The majority of women (84%) were satisfied with the surgical result. Presence of severe pain symptoms after the hysterectomy was associated with less satisfaction (P < 0.001). Pain symptoms after surgery, patient satisfaction and the patient's perceived improvement were not significantly different between women whose ovarian tissue was preserved and women who underwent bilateral oophorectomy. Conclusions: We observed a significant, long-lasting reduction in pain symptoms after hysterectomy among women with endometriosis. Hysterectomy, with the possibility of ovarian preservation, may be a valuable option for women with endometriosis who suffer from severe pain symptoms. Tweetable abstract: Hysterectomy is a valuable option for women with endometriosis and severe pain symptoms
