Initial experience with and surgical outcomes of da Vinci single-port system in general thoracic surgery

Abstract

Background: The da Vinci single-port system (SPS) (Model SP1098, Intuitive Surgical Inc., Sunnyvale, CA, USA) has been used in genitourinary and general surgical procedures; however, its clinical application in general thoracic surgery has not been attempted. This retrospective study investigated the clinical outcomes of SPS in general thoracic surgery.

Methods: After approval from the Ministry of Food and Drug Safety in Korea, the surgical details of SPS in simple thoracic surgeries at two independent institutions were collected and retrospectively reviewed.

Results: Overall, 17 surgeries were performed using SPS without conversion to multiport surgery. The patients included six males, and the overall median age was 52 years (range, 28-83 years). The commonest pathological diagnoses were thymoma (8 cases) and benign cystic lesions (6 cases). The approach for SPS was subxiphoid, subcostal, and intercostal in 11, 4, and 2 cases, respectively. All patients underwent the surgeries without complications. The median operation time and peak pain score were 120 minutes (range, 58-250 minutes) and 3 (range, 2-4). The median duration of in situ chest tube and hospital stay was 1 day (range, 1-2 days) and 3 days (range, 2-7 days), respectively. SPS showed a shorter duration of in situ chest tube and hospital stay than robotic single-site surgeries.

Conclusions: The application of SPS in the field of general thoracic surgery is feasible and can be successful. Although this study reported preliminary data and the cases were relatively simple, advanced and complex procedures should be attempted with the SPS in the near future.
