P04.05 - Efficacy of Uniportal Video-Assisted Thoracic Surgery (U-VATS) Simple Segmentectomy for Early Lung Cancer (ID 3871)

- Abstract
Introduction
Uniportal video-assisted thoracic surgery (U-VATS) has already spread over the world, especially in Asia. My purpose is to
assess the feasibility and safety of U-VATS simple segmentectomy using electrocautery and stapler for clinical stage I lung cancer.
Methods
U-VATS segmentectomy (42) was performed for stage I lung cancer between 2013 and 2020. In uniportal segmentectomy , an approximately 4-cm small incision was placed at the fourth or fifth intercostal space from the anterior to posterior axillary line. Segmentectomy using electrocautery (SE:n=18) or segmentectomy using stapler (SS:N=24) for early lung cancer was carried out. The evaluation items were general operative outcomes, pain stress using the numeric rating scale (NRS) on postoperative day 30. All segmentectomies were simple segmentectmies.
Results
SE showed similar perioperative outcomes (blood loss, operation time, drainage duration, postoperative hospital stay, the number of lymph node retrieval and frequency of postoperative complications compared to SS. The most frequent segment removed was the S6 (13 cases, 31%). The mean operation time(min.) in ES and SS was 165±19 and 148±18 , respectively. and also there was no significant difference between SE and SS in regard to blood loss, the number of lymph node retrieval, drainage duration, hospital stay, conversion to thoracotomy, and the frequency of air leakage more than 7 days. Additionally, the average NRS in SE was almost the same as that in SS on postoperative day 30 (SE:2.3 ± 0.5 vs. SS:2.4 ± 0.7, P=0.62). 5-years disease free survival rate was 94.4% in all cases.
Conclusion
U-VATS simple segmentectomy for early lung cancer was safe and feasible. Generally, U-VATS segmentectomy was performed using stapler, however U-VATS surgeons should also master the technique using electrocautery in view of surgical margin and residual lung function.
