Two-Centimeter Single-Port Incision Minimizing Intercostal Nerve Damage Applied in Video-Assisted Thoracoscopic Surgery Segmentectomy for Pulmonary Ground Glass Nodules.

Purposes: We introduced a novel modified 2-cm single-port incision made by blunt separation minimizing intercostal muscle and nerve damage applied in video-assisted thoracoscopic surgery (VATS) segmentectomy, and compared it with the traditional single-port incision or the novel incision plus a 3-mm tiny port, aiming to explore a more minimally invasive single-port technique for VATS segmentectomy. Materials and Methods: We retrospectively analyzed the clinical data of 174 pulmonary ground glass nodule patients who received single-port VATS segmentectomy (54 modified 2-cm single port, 67 modified single port plus tiny port, and 53 traditional single port, respectively) in our medical center from May 2020 to December 2022. Three kinds of approaches were compared retrospectively, concerning their safety, feasibility, and postoperative pain. Results: There were no serious complications and mortality in either group. The blood loss, tube duration, and hospitalization time were comparable among the three groups ( P  > .05). The 2-cm single-port and 2-cm single-port plus tiny-port group were obviously more advantageous in the visual analog scores of postoperative pain, the wound numbness, incision healing and appearance than that in the traditional group ( P  < .05), while they were comparable. Notably, the operation time of the 2-cm plus tiny-port group was shorter than that of the 2-cm group ( P  < .05) and similar to the traditional single-port group. Conclusions: The 2-cm modified single-port applied for VATS segmentectomy is feasible and safe, and has obviously advantages in postoperative pain, numbness, and appearance of incision. With addition of tiny port, the convenience of the operation can be significantly increased without increasing pain. Our finding could provide a promising new incision mode for VATS segmentectomy.
