Pdf Summary

This study aimed to compare the intraoperative and acute surgical outcomes of the minimally invasive open surgery (MIOS) approach to video-assisted thoracic surgery (VATS) in patients with stage I lung cancer. The MIOS approach, performed through an 8-cm thoracotomy, offers direct vision during surgery and the ability to manage emergencies. A total of 474 patients with stage I lung cancer who underwent lobectomies using either MIOS or VATS were evaluated. <br /><br />Results showed that MIOS had shorter operative times and less blood loss compared to VATS. There were no significant differences in acute postoperative surgical outcomes between the two approaches. The median operative time for MIOS was 139 minutes compared to 174 minutes for VATS. Median blood loss was 11 g for MIOS and 60 g for VATS. The number of dissected lymph nodes was similar between MIOS (16) and VATS (14). The frequency of patients requiring a blood transfusion was 0.5% for MIOS and 2.2% for VATS. The frequency of grade 2 postoperative complications was 11.6% for MIOS and 16.7% for VATS. The median duration of chest tube drainage, postoperative hospital stay, and readmission within 30 days after discharge were all comparable between the two approaches. However, there was one death within 30 days after surgery using the VATS approach. <br /><br />In conclusion, the MIOS approach for lung cancer surgery showed superior intraoperative outcomes compared to VATS, with shorter operative times and less blood loss. There were no significant differences in acute postoperative surgical outcomes. These findings suggest that wound size is not essential in determining the success of lung cancer surgery.
