Routine hysterectomy for large asymptomatic uterine leiomyomata: a reappraisal.

As part of an ongoing quality improvement process, the records of 104 consecutive patients undergoing hysterectomy for uterine leiomyomata were reviewed. The diagnosis was confirmed histologically in 93 cases (89%) and in eight of the remaining 11, other disease such as adenomyosis or an ovarian neoplasm was discovered. The 93 consecutive patients with a confirmed diagnosis of uterine leiomyomata were then stratified according to preoperative estimate of uterine size and actual uterine weight. The physician's clinical estimate of uterine size correlated well with specimen weight (r = 0.65, P less than .001). Intraoperative estimated blood loss correlated less well with actual change in hematocrit (r = 0.31, P = .03). Women with a uterine size estimate larger than 12 weeks' gestation were no more likely to suffer perioperative complications than were those with smaller uteri. Furthermore, there was no significant increase in mean estimated blood loss or blood transfusion in women with larger uteri compared with those with smaller uteri. We conclude that there is no increase in adverse short-term outcomes associated with hysterectomy for leiomyomata in women with uteri greater than 12 weeks' size. Therefore, hysterectomy need not be routinely recommended to asymptomatic women with larger uteri as prophylaxis against increased operative morbidity associated with future growth.
