High MIH case volume may up risk for adverse events in women with large uteri

Even after investigators controlled for age, body mass index, uterine weight, history of laparotomy, and parity, as well as surgeon volume and operative time, they found that higher monthly MIH volume, estimated blood loss, and operative time remained significantly associated with both intraoperative adverse events (adjusted odds ratios, 1.9, 2.0, and 22.1, respectively) and postoperative adverse events (aOR, 1.3, 1.4, and 1.9, respectively), she said.

Higher BMI was associated with a lower incidence of intraoperative complications (aOR, 0.1).

“As for conversion to laparotomy, increasing surgeon volume was associated with a lower incidence of conversion (aOR, 0.4), but higher estimated blood loss and uterine weight were associated with a higher incidence of conversion (aOR, 2.6 and 7.1, respectively).”

Study subjects were women with a mean age of 47 years and mean BMI of 31 kg/m² who underwent MIH during January 2014–June 2016 at a tertiary care referral center. Median uterine weight was 409 g, and indications for hysterectomy included fibroids, pelvic pain, abnormal uterine bleeding, and prolapse. Patients with malignancy were excluded.
