  Objective: The feasibility of systematic node dissection (SND) for stage 1 primary lung cancer by video-assisted thoracic surgery (VATS) remains controversial. The aim of this study was to assess the feasibility of SIND by VATS. Methods: Four hundred and eleven patients with clinical stage I primary lung cancer were enrolled in this study. Two hundred and twenty-one patients, VATS group, underwent a major pulmonary resection with SIND by VATS through a minithoracotomy (30-70 mm) and two access ports; 190 patients, open thoracotomy (OT) group, did so through anterolateral thoracotomy. The two groups were compared regarding clinical data including number of dissected nodes in each nodal station for evaluating the feasibility of SND by VATS. Results: In the right side, the total number (N) of nodes dissected (VATS 31 vs OT 31, P=0.899), N of mediastinal nodes dissected (20 vs 21, P=0.553), and N of dissected nodes in each nodal station were similar between the two groups. In the left side, total N of nodes dissected (28 vs 27, P=0.714), N of mediastinal nodes dissected (16 vs 17, P=0.333), and N of dissected nodes in each nodal station were similar between the two groups. There were three (1.4%) and five (2.6%) operation related deaths in the VATS group and OT group, respectively (P=0.48). Chest tube duration was shorter in the VATS group than the OT group (5.8 vs 7.6 days, P=0.001). The incidences of chylothorax, recurrent laryngeal nerve injury and pleural effusion requiring thoracentesis after surgery were similar between the two groups (3 vs 4, P=0.709; 5 vs 3, P=0.4807 3 vs 8, P=0.122). The 5-year actuarial recurrence-free survival rate and cumulative survival rate of pathological stage IA cases were similar between the two groups (88.6 vs 92.4%, P=0.698; 92.9 vs 86.5%, P=0.358). Conclusions: The SND by VATS was as technically feasible as SND through OT regarding number of dissected nodes and morbidity. It seems acceptable as an oncological treatment for clinical stage 1 lung cancer. © 2005 Elsevier B.V. All rights reserved.

  In this report, we describe a new, easy method for putting "U" stitches inside the chest wall. The method does not require extension of the skin incision nor subcutaneous dissection and it minimizes chest wall injury. This method may also be applied to other surgical fields where needles can penetrate the wall of the cavity when it is difficult to stitch from the inside of the cavity.
