Objective: To determine the rate of oophorectomy and associated factors at the time of hysterectomy in premenopausal women with benign diseases.
Materials and Methods: The medical records of the premenopausal women that underwent hysterectomy with or without oophorectomy due to benign gynecologic conditions between January 1, 2012 and December 31, 2017 at Khon Kaen University Hospital (Thailand) were retrospectively reviewed. The data collected included age, BMI, parity, indication for surgery, family history of carcinoma, route of hysterectomy, procedure, specialization of the surgeon, operative notes, and histopathological reports of the ovaries.
Results: Six hundred thirty-eight subjects underwent hysterectomy due to benign gynecologic conditions. Bilateral salpingo-oophorectomy (BSO) was performed in 57.37% (366) of the cases. In 81.97% (300) of these cases, either one or both patient’s ovaries were grossly normal. The rate of prophylactic oophorectomy among all cases was 47.02% (300 in 638). The strongest associated factor with BSO was age (odds ratio 8.421, 95% CI 5.488 to 12.921). Other associated factors were irregular menstrual history, the surgeon being a gynecologic oncologist, and abdominal hysterectomy. No cases of ovarian cancer were found.
Conclusion: Nearly half of premenopausal women that underwent hysterectomy due to benign conditions underwent prophylactic oophorectomy. Associated factors were age, irregular menstruation, the surgeon being a gynecologic oncologist, and abdominal hysterectomy.
