Uterine weight as a predictor of morbidity after a benign abdominal and total laparoscopic hysterectomy.

OBJECTIVE

To determine if an enlarged uterus is associated with an increased rate of intraoperative and postoperative complications and prolonged hospital length of stay (LOS) after benign total abdominal hysterectomy (TAH) or total laparoscopic hysterectomy (TLH).

STUDY DESIGN

Women who underwent TAH or TLH were stratified, according to uterine weight, into 3 groups: group 1, uterine weight < 200 g; group 2, 201-500 g; and group 3, > 500 g. Indications included uterine leiomyomas, chronic pelvic pain, prolapsed uterus, endometriosis and adenomyosis, dysfunctional uterine bleeding; all had benign final pathology. Statistical analysis compared risks of intraoperative and postoperative morbidity and prolonged hospital stay.

RESULTS

Prolonged hospital stay risk increased for uterine weight > 500 g (p < or = 0.001). There was a significant association between postoperative complications and uterine size (p < or = 0.001). Mean estimated blood loss (EBL) also increased with uterine weight > 500 g (p < or = 0.001). TLH was associated with fewer postoperative complications, shorter LOS and reduced EBL (p < or = 0.001).

CONCLUSION

Average LOS and risk of blood loss, blood transfusion and other postoperative complications after hysterectomy for benign disease increased with increasing uterine weight. TLH is an excellent alternative for enlarged uteri; it was strongly associated with decreased morbidity, shorter LOS, and reduced EBL and blood transfusion rate in all uterine weight groups when adjusted for other variables.
