OBJECTIVE: To compare perioperative outcome of robot-assisted radical hysterectomy with abdominal radical hysterectomy for early-stage cervical cancer and endometrial cancer and to evaluate the feasibility of robotic-assisted radical hysterectomy. METHODS: We reviewed medical record of 37 patients who had radical hysterectomy at Hallym university for cervical cancer stage Ia1 to IIa and endometrial cancer stage Ia to Ib. Abdominal radical hysterectomy was carried out in 27 (Abdominal group) patients and robot-assisted radical hysterectomy carried out in 10 patients (Robotic group). We compared patient's characteristics between two groups. Perioperative characteristics compared included cancer stage, operative time, number of nodes, estimated blood loss, length of hospital stay and complications. RESULTS: There were no differences in age, parity, history of medical disease, body mass index between two groups (p>0.05). Robotic operative times were significantly longer than for abdominal (480.0+/-117.8 vs. 286.9+/-65.6 min, p<0.0001). Blood loss (660.0+/-245.9 vs. 1,137.0+/-608.4 mL. p<0.0001) and length of hospital stay (7.2 versus 17.1 days, p<0.0001) were significantly lower for the robotic group. Lymph node yield in the robotic group was equivalent to that for the abdominal group (30.1+/-8.7 vs. 35.4+/-16.9, p=0.356). No major operative complications occurred with both groups. CONCLUSION: Robot-assisted radical hysterectomy appears safe and feasible in early-stage cervical and endometrial cancer.
