“…Twenty studies reported total inpatient LoS of < 10 days; none of these studies used an open approach for the thoracic or abdominal phases. 25 , 41 , 43 , 44 , 52 , 56 – 69 In comparison, 27 studies reported total LoS > 14 days, of which six used an open approach in either the abdominal or thoracic phases. 5 , 24 , 25 , 33 , 42 , 45 , 46 , 55 , 70 – 85 This indicates the robotic and conventional minimally invasive approaches are associated with shorter LoS, however clinical trials are required to validate this.…”
