Impact of uterine weight on robotic hysterectomy: Analysis of 500 cases in a single institute

摘要

BACKGROUNDS: Robotic surgeries have been used frequently for benign diseases in gynecology. However, the advantage of robotic surgery for huge uterus is unclear. METHODS: We analyzed surgical outcomes of 527 patients who underwent robotic hysterectomies for benign diseases, separating uterine sizes into five groups by every 250 g. RESULTS: Median operative time in the five groups was 123 minutes (<250 g), 130 minutes (250-500 g), 144 minutes (500-750 g), 180 minutes (750-1000 g), and 170 minutes (>1000 g). Median estimated blood loss was 50, 100, 100, 200, and 400 mL in the five groups, respectively. The incidence of intraoperative complications did not correlate with uterine weight. CONCLUSIONS: Operative time, estimated blood loss, and the incidence of conversion to laparotomy increased with uterine size during robotic hysterectomies, especially evident in a uterus >750 g.
