Association Between Body Mass Index, Uterine Size, and Operative Morbidity in Women Undergoing Minimally Invasive Hysterectomy

Major operative morbidity after minimally invasive hysterectomy is rare regardless of the surgical approach. A vaginal approach to hysterectomy is associated with the shortest operative times, but increasing BMI results in a rapid escalation of operative time in women with large uteri. Total laparoscopic hysterectomy is associated with shorter hospitalizations and lower odds of blood transfusion across the BMI spectrum, particularly in women with small uteri. Laparoscopic-assisted vaginal hysterectomy appears to confer no specific advantage over the vaginal or laparoscopic approaches.
