Uterine Weight & Complications After Hysterectomy

Am J Obstet Gynecol; ePub 2018 Jun 27; Louie, et al

Uterine weight is an independent factor for post-hysterectomy complications, with abdominal hysterectomy having higher odds of any complication, compared to laparoscopic hysterectomy, a recent study found. Researchers sought to determine if there is an association between uterine weight and post-hysterectomy complications and if differences in that association exist among vaginal, laparoscopic, and abdominal approaches. Patients were compared with respect to 30-day postoperative complications and uterine weight, stratified by surgical approach. They found:

  • 27,167 patients were included in the analysis.
  • After adjusting for confounders, women with 500 g uteri were >30% more likely to have complications compared to those with uteri ≤100 g, women with 750 g uteri were nearly 60% as likely, and women with uteri ≥1000 g were >80% more likely.
  • The incidence of 30-day post-surgical complications was nearly double in the abdominal hysterectomy group compared to the laparoscopic group.
  • Larger hysterectomies can safely be performed laparoscopically.
