Comparison of Robotic-Assisted Hysterectomy to Other Minimally Invasive Approaches

OBJECTIVE To compare surgical outcomes for robotic assisted total laparoscopic hysterectomy (RH) to other minimally invasive hysterectomy (MIH) types, including total laparoscopic hysterectomy (TLH), laparoscopic-assisted vaginal hysterectomy (LAVH), and vaginal hysterectomy (VH). METHODS Retrospective cohort study of all patients who underwent RH or MIH for benign indications between January 2007 and May 2010 at 2 Henry Ford Health System teaching hospitals. Age, race, body mass index (BMI), procedure duration, estimated blood loss (EBL), peri-operative hemoglobin change, uterine weight, length of hospital stay (LOS), and complications were collected from electronic medical records and were compared between RH and MIH groups. RESULTS Included in the analysis were 135 RH and 162 MIH cases (n = 34 VH, n = 82 LAVH, n = 46 TLH). There were no differences in age, race, or BMI between groups, but RH patients had significantly larger uteri (P = .007; RH, 13.5%>500g; MIH 4.0%>500g). MIH patients had significantly greater EBL (P < .001) and drop in hemoglobin (P = .02) than RH patients with a 150 mL difference in median EBL (200 mL versus 50 mL) between groups. RH had longer procedure durations than MIH (P = .0002) overall, but not compared to the TLH subgroup. RH patients had a shorter LOS than MIH patients had (P = .02) who had a longer LOS for LAVH patients. Although readmission and major complication rates were similar in both groups, minor adverse events occurred more frequently in the MIH group (21.6%) than the RH group (8.9%) (P = .003). CONCLUSION RH has comparable surgical outcomes, and possibly decreased blood loss, shorter length of stay, and fewer minor complications than other methods of MIH.
