Robotic versus abdominal hysterectomy for very large uteri.

BACKGROUND AND OBJECTIVES

We sought to examine the outcomes of patients with myomatous uteri weighing >1000 g who underwent hysterectomy by one of two modalities, either with a robotic system or by laparotomy.

METHODS

All patients who underwent robotic hysterectomy for uteri weighing >1000 g at our institution between May 2007 and January 2011 were identified, and a retrospective chart review was performed. These patients were matched to a laparotomy control group by body mass index and uterine weight, and the postoperative outcomes in both groups were analyzed and compared.

RESULTS

Sixty patients with uteri weighing >1000 g underwent hysterectomy, 30 with the robotic system and 30 by laparotomy. The median body mass index was 31.8 kg/m(2) (range, 18.5-56.3 kg/m(2)) and the median uterine weight was 1259 g (range, >1000 -3543 g) in the robotic group versus 30.2 kg/m(2) (range, 18 - 48 kg/m(2)) and 1509 g (range, 1000 -3570 g), respectively, in the laparotomy group (P = .31). The median operating time was 255 minutes (range, 180 -372 minutes) in the robotic group versus 150 minutes (range, 100 -285 minutes) in the laparotomy group (P < .001). There were no conversions to laparotomy. In both groups the operative time was not increased with increasing specimen weight. The median blood loss was 150 mL in the robotic group versus 425 mL in the laparotomy group. Of 30 patients in the robotic group, 23 (76.6%) were discharged from the hospital on postoperative day 1. The median hospital stay for the robotic group was 1 day, and for the laparotomy group, it was 2.5 days (P < .01).

CONCLUSION

Robotic surgeries for very large myomatous uteri are feasible and have minimal morbidity even in morbidly obese patients. The robotic surgery requires a longer operative time but results in a shorter hospital stay and decreased intraoperative blood loss.
