Robotic Single-Site Hysterectomy versus Robot-Assisted Multiport Hysterectomy in Benign Gynecologic Diseases: A Retrospective Comparison of Clinical and Surgical Outcomes

ABSTRACT

OBJECTIVE: The purpose of this study was to compare clinical and surgical outcomes of robotic single-site hysterectomy (RSSH) and robot-assisted multiport hysterectomy (RH) in benign disease. METHODS: We retrospectively reviewed the medical records of 38 women who underwent RSSH (N=12) or RH (N=26) for the treatment of benign uterine disease between June 2015 and November 2017. RESULTS: There were no intergroup differences in parity, comorbidities, and number of previous abdominal surgery. Mean age was older (49.5±5.05 years vs. 44.4±3.54 years, P=0.001) and mean body mass index was higher (27.4±2.47 kg/m2 vs. 25.3±3.12 kg/m2, P=0.045) in RSSH group than RH group. Surgical outcomes, including operative time (165.0 minutes vs. 159.2 minutes, P=0.727), estimated blood loss (115.8±33.15 mL vs. 108.1±56.42 mL, P=0.662), uterus weight (445.9±157.21 g vs. 374.5±197.91 g, P=0.291), postoperative hospital stay (5.4±0.51 days vs. 5.8±1.20 days, P=0.289), postoperative hemoglobin change in day 1 (1.8±0.89 g/dL vs. 1.4±1.53 g/dL, P=0.431) and day 3 (2.1±1.32 g/dL vs. 1.7±1.83 g/dL, P=0.601), and perioperative complications did not significantly differ between two groups. The use of additional analgesics after 6 hours, 24 hours, and 48 hours, and mean NRS score after 6 hours, 24 hours, and 48 hours were not significantly different between two groups. CONCLUSION: RSSH might be an effective and safe alternative to RH, even if in older and/or obese women with large uteri.
