A retrospective comparative cohort study on the efficacy and safety of bi-port robotic-assisted lobectomy and multi-port robotic-assisted lobectomy

Abstract

Background: The pursuit of less surgical incisions brings better postoperative experience of patients and earns extensive popularity recently. As the update to the da Vinci robotic surgical system has reduced the size of the robotic arm, a new surgical method with fewer ports has become feasible. We performed 20 cases of robotic surgery with only 2 ports and compared the efficacy and safety between bi-port robotic-assisted lobectomy and multi-port robotic-assisted lobectomy. Methods: To compare the efficacy and safety of the different surgery strategies, we retrospectively reviewed 20 cases of bi-port robotic-assisted thoracic surgery (RATS) and 40 cases of multi-port RATS which were performed at the Shanghai Chest Hospital Between February 2021 and May 2021. The baseline characteristics and their perioperative data were collected and analyzed. Chest tube drainage, chest tube removal time, lymphadenectomy outcomes, operation duration were collected to compare the efficacy of the two groups and blood loss, perioperative complications were recorded to value the safety. Results: 5.1±1.3 days in the bi-port surgery group and control group. No statistical significance was found between the two groups (P>0.05). Conclusions: Compared to multi-port RATS, Bi-port robotic-assisted lobectomy was safe and showed promising efficacy in patients with early staged operable lung cancer.
