Background: In this study, we aimed to evaluate the effects of the transition from the 6th edition of the Tumor, Node, Metastasis (TNM) staging system to the 7th edition, and from the 7th edition to the 8th edition by comparing the stage migrations. We also aimed to externally validate the 8th edition of the TNM staging system. Methods: Between September 2005 and June 2015, a total of 1,077 patients (986 males, 91 females; mean age: 59.6±8.3 years; range, 35 to 84 years) with non-small cell lung cancer who underwent lung resection were retrospectively analyzed. We re-staged patients according to 6th, 7th, and 8th TNM staging and compared the stage migrations of cases among the three staging systems. Results: Stage migration in the transition to the 7th edition of the TNM staging system was observed in 368 (34.1%) patients whereas it was observed in 541 (50.2%) patients in the transition to the 8th edition (p<0.001). The rate of upstaging in transition to the 7th edition staging system was 50.2% (n=185), whereas it was 98.1% (n=531) for the transition to the 8th edition (p<0.001). The survival rates of Stages 1B, 2B and 3A increased with transition to the 7th edition and the survival rates of Stages 1B, 2A, 2B, 3A, and 3B increased with the transition to the 8th edition. The best stratification in the survival curves in the 6th edition was between 1B-1A and 3B-3A. In the 7th edition, it occurred between 1B-1A, 3A-2B and 3B-3A and, in the 8th edition, between 1B-1A and 3B-3A. Conclusion: Stratification according to the 7th edition showed better prognostic validity compared to the 6th edition; and that of the 8th edition was better compared to the 7th edition.

Background: Our aim in this study was to compare the results of video-assisted thoracoscopic surgery with those of open surgery regarding efficacy, morbidity, and long-term recurrence of bronchogenic cysts in light of the literature. Methods: This study comprises the data of 51 patients whose pathological diagnosis revealed bronchogenic cyst after surgical excision between January 2010 and December 2016. There were two groups according to the type of resection: video-assisted thoracoscopic surgery (VATS) and thoracotomy. Results: Of the patients included in the study, 25 (49%) were male and 26 (51%) were female. Their average age was 41.7 ± 14.1 years. While 14 patients (27.5%) were asymptomatic in the preoperative period, 37 patients (72.5%) had symptoms. The Charlson Comorbidity Index was 0 in 35 patients (68.6%) and 1 and above in 16 patients (31.4%). While 22 (43.1%) patients underwent cyst excision via VATS, 29 (56.9%) patients underwent thoracotomy. The average length of hospital stay was 1.77 ± 0.68 days for patients who had VATS, whereas it was 3.82 ± 3.3 days for patients who had thoracotomy (p <0.001). Conclusion: VATS procedure is a safe method in the surgical treatment of bronchogenic cysts, with less hospitalization and similar recurrence rates.

Background: Although postoperative hemorrhage after thoracic surgery is uncommon, it is the most common indication for revision surgery after these procedures. Most postoperative hemorrhages are due to surgical technique, although some comorbidities can predispose the patient to bleeding. We investigated whether video-assisted thoracoscopic surgery (VATS) and re-thoracotomy had the same outcomes in the management of postoperative hemorrhage in patients who underwent open thoracotomy or VATS. Materials and Methods: We retrospectively analyzed patients with postoperative hemorrhage after thoracotomy (n = 659) or VATS (n = 883) between 2018 and 2020. Revision surgery was performed after thoracotomy in 22 patients (3.3%) and after VATS in 4 patients (0.4%). Of these, 11 patients (42.3%) were re-operated by re-thoracotomy (Re-thoracotomy Group) and 15 patients (57.7%) by revision VATS (VATS Group).Results: Revision due to postoperative hemorrhage was required significantly more frequently after thoracotomy than VATS (3.3% vs. 0.4%, p < 0.001). In patients with hemorrhage after pneumonectomy (n = 14), revision by VATS was preferred to re-thoracotomy (n = 10, 71.4% vs. n = 4, 28.6%). The mean time to discharge after revision surgery was 5.1 ± 2.2 days (range, 2-12 days) overall and was significantly shorter in the revision VATS Group than in the Re-thoracotomy Group (4.4 ± 1.5 days vs. 6.2 ± 2.5 days, p = 0.004).Conclusions: VATS has similar results to re-thoracotomy and is advantageous in terms of earlier recovery and shorter hospital stay. Therefore, VATS should be the preferred method for postoperative hemorrhage management.
