Background: Minimally invasive surgery (MIS) techniques, currently considered the gold standard in the treatment of early-stage non-small cell lung cancer (NSCLC), are mainly represented by video-assisted thoracoscopic surgery (VATS), both uniportal and multiportal, and by robotic-assisted thoracoscopic surgery (RATS). While multiportal RATS has been accepted as a valid alternative to VATS, carrying the advantages of three-dimensional high-definition visualisation and improved maneuverability, very few reports exist in literature on the application of uniportal RATS (U-RATS). Therefore, we describe our initial experience with this recently developed method in the treatment of early-stage NSCLC.
Materials and methods: U-RATS was conducted through a single 4 cm long antero-lateral mini-thoracotomy (ALMT) in the sixth intercostal space at the mid-axillary line. Three 8 mm robotic trocars were positioned and connected, from back to front, to robotic arms as follows: 30° camera arm, robotic arm 2 (bipolar fenestrated grasper) and 1 (Maryland bipolar forceps). Assistant access was identified as the most anterior part of ALMT.
Results: Case 1: an 82-year-old woman (American Society of Anaesthesiologists [ASA III]) underwent a left S6 segmentectomy for a clinical stage IA2 NSCLC, complicated by an air leak that resolved spontaneously by postoperative day three (POD 3). Case 2: a 75-year-old man (ASA III) underwent an uncomplicated right lower lobectomy for a clinical stage IA3 NSCLC. Case 1 and 2 were discharged on POD 5 and 4, respectively.
Conclusions: From what emerged in our small series, U-RATS with the Da Vinci Xi surgical system might be considered a safe, reliable, and effective alternative to other MIS techniques. Larger prospective studies are required to validate these findings.
