Objective: To compare surgical morbidity and clinical-pathologic factors for patients with endometrial cancer (EC) undergoing robotic-assisted laparoscopic hysterectomy (RALH) versus total abdominal hysterectomy (TAH) with aortic and/or pelvic lymphadenectomy (LA).
Methods: During the first 14 months of a robotics surgical program, 56 patients with EC were scheduled to undergo RALH with LA. Cases were analyzed for operative (op) time, estimated blood loss (EBL), transfusion, intra- and post-op complications, surgical-pathologic data, patient demographics and length of stay (LOS). Data was compared to 106 serially treated patients with EC who underwent TAH with LA immediately prior to initiation of our robotics program.
Results: Three robotic cases (5.4%) were converted to TAH secondary to intra-op factors. FIGO stages for RALH vs. TAH were: stage I (82 vs. 69%), stage II (7 vs. 7.5%) and stage III (11 vs. 21.5%). Patients' mean age was 59+/-10 vs. 63+/-11 years (p=0.05) and body mass index (BMI) was 29+/-6.5 vs. 34+/-9 kg/m(2) (p=0.0001) for the robotic and open groups, respectively. Severe medical co-morbidities affected 5.4% of robotic patients compared to 8.5% of open cases (p>0.05). Comparing RALH and TAH, mean op time was 177+/-55 vs.79+/-17 min (p=0.0001), EBL was 105+/-77 vs. 241+/-115 ml (p<0.0001), transfusion was 0 vs. 8.5% (p=0.005), and LOS was 1.0+/-0.5 vs. 3.2+/-1.0 days (p<0.0001). Robotic patients incurred a 3.6% major peri-operative complication rate while women undergoing open procedures had an incidence of 20.8% (p=0.007). Total lymph node count was 19+/-13 nodes for robotic cases vs. 18+/-10 nodes obtained from open hysterectomy patients.
Conclusions: Patients with EC who underwent RALH with LA during the first year of our robotics program were younger, thinner and had less cardio-pulmonary illness than patients previously treated with TAH and LA. LOS, EBL and peri-op complication rates were significantly lower for the robotic cohort.
