Completely portal robotic lobectomy in lung cancer: is subcostal specimen removal necessary?

Background: The best place for specimen extraction is a relevant question since either after robotic or video-thoracoscopic lobectomy, both intercostal and subcostal routes can be potential extraction routes. In this study, we studied completely portal robotic lobectomies (CPRL-4) for pulmonary neoplasms to investigate the efficacy and feasibility of subcostal specimen removal by comparing the two techniques.

Material and methods: Between January 2014 and July 2021, data from 90 patients who underwent robotic thoracic surgery with a Da Vinci Surgical System SI (Intuitive Surgical Inc., Mountain View, California, USA) were collected and retrospectively analyzed. Out of 90 patients, we analyzed 36 CPRL-4 cases. We removed specimens traditionally via intercostal utility thoracotomy in the first 22 patients (group A) and via subcostal incision in the next consecutive 14 patients (group B). Operative parameters, postoperative parameters, the visual analog scale (VAS) and SF36 life quality scoring were comparatively analyzed.

Results: The mean docking time was significantly higher in group B than in group A (26.2 ± 5.3 vs 17.8 ± 4.1) (p = .001). In terms of early-stage postoperative pain, group B had significantly lower pain scores compared to group A (p < .05). There was no significant difference between the groups in terms of SF36 life quality scoring.

Conclusion: We can conclude that performing a subcostal incision is not a sophisticated process, though it significantly prolongs the docking time. Although our study is based on a small group, we noticed that removing the specimen through the subcostal incision after CPRL-4 is potentially useful, has several advantages and it is a practical, feasible, and safe method.
