Abstract
BACKGROUND: Systematic lymph node dissection is an important part of radical resection for lung cancer. Insufficient incision of the mediastinal pleura results in a tapered or tunnel-like operation surface, which increases the difficulty of uniportal video-assisted thoracoscopic mediastinal lymph node dissection. The objective of this study was to report our concept of broad exposure and investigate the efficacy and safety of this concept in uniportal video-assisted thoracoscopic mediastinal lymph nodes dissection. METHODS: We retrospectively analyzed the clinical data of the 204 non-small cell lung cancer patients who underwent uniportal video-assisted thoracoscopic surgery for anatomical lobectomy and systematic lymph node dissection following the concept of broad exposure. SPSS 23.0 software was used for statistical analysis. RESULTS: All operations were completed under uniportal video-assisted thoracoscopic surgery following the concept of broad exposure. The median surgery time was 102 (range, 76-285) minutes and the median blood loss was 50 (range, 20-900) milliliters. The median chest tube duration time was 2 (range, 1-6) days, the median postoperative hospital duration time was 5 (range, 4-10) days. The median number of dissected lymph node stations and dissected lymph nodes were 8 (range,6-9) and 15(range,12-19), respectively. The median number of dissected mediastinal lymph nodes stations and dissected mediastinal lymph nodes were 5(range,3-6) and 11(range,10-15), respectively. The up-staging rate of N staging was 6.86%. The postoperative complication rate was 10.29% and there was no perioperative death. CONCLUSIONS: According to our results, it's effective and safe to perform uniportal video-assisted thoracoscopic mediastinal lymph nodes dissection following the concept of broad exposure. This new concept not only emphasizes sufficient exposure, but also focuses on protection of important tissues.
