Modified 2-cm super single port vs. the traditional 3-cm single port for video-assisted thoracoscopic surgery lobectomy.

PURPOSES We introduce a novel 2-cm single port designed to minimize intercostal muscle and nerve damage in video-assisted thoracoscopic surgery (VATS) lobectomy, and compared it with the 3-cm traditional single port. METHODS We analyzed, retrospectively, the clinical data, safety, convenience, incision complications, and postoperative pain and numbness in 81 patients who underwent either modified (n = 42) or traditional (n = 39) single-port VATS lobectomy. RESULTS The preoperative variables were comparable between both single-port VATS lobectomy groups after matching. There were no serious complications and there was no mortality in either group. There were no remarkable differences between the groups in intraoperative blood loss, chest tube duration, lymph node dissection, or postoperative complications. The modified single-port group had a longer operation time (p < 0.05), but the static and dynamic postoperative VAS scores and incisional numbness were better in the modified single-port group (p < 0.05). The modified single-port group also had an obvious advantage in incision seepage, healing, and appearance. CONCLUSIONS Our 2-cm modified single port for lobectomy is safe and effective, and results in less postoperative pain and incisional numbness than the 3-cm traditional single port.
