Abstract

Importance: Minimally invasive colectomies are increasingly popular options for colon resection.
Objective: To compare the perioperative outcomes and costs of robot-assisted colectomy (RC), laparoscopic colectomy (LC), and open colectomy (OC).
Design, setting, and participants: The US Nationwide Inpatient Sample database was used to examine outcomes and costs before and after propensity score matching across the 3 surgical approaches. This study involved a sample of US hospital discharges from 2008 to 2010 and all patients 21 years of age or older who underwent elective colectomy. MAIN OUTCOMES AND MEASURES In-hospital mortality, complications, ostomy rates, conversion to open procedure, length of stay, discharge disposition, and cost.
Results: Of the 244129 colectomies performed during the study period, 126284 (51.7%) were OCs, 116261 (47.6%) were LCs, and 1584 (0.6%) were RCs. In comparison with OC, LC was associated with a lower mortality rate (0.4% vs 2.0%), lower complication rate (19.8% vs 33.2%), lower ostomy rate (3.5 vs 13.0%), shorter median length of stay (4 vs 6 days), a higher routine discharge rate (86.1% vs 68.4%), and lower overall cost than OC ($11742 vs $13666) (all P<.05). Comparison between RC and LC showed no significant differences with respect to in-hospital mortality (0.0% vs 0.7%), complication rates (14.7% vs 18.5%), ostomy rates (3.0% vs 5.1%), conversions to open procedure (5.7% vs 9.9%), and routine discharge rates (88.7% vs 88.5%) (all P>.05). However, RC incurred a higher overall hospitalization cost than LC ($14847 vs $11966, P<.001).
Conclusions and relevance: In this nationwide comparison of minimally invasive approaches for colon resection, LC demonstrated favorable clinical outcomes and lower cost than OC. Robot-assisted colectomy was equivalent in most clinical outcomes to LC but incurred a higher cost
