Background: This study aimed to compare early results in patients who underwent subxiphoid wedge resection with those operated on using a multiportal approach. Methods: We retrospectively evaluated 151 patients who underwent diagnostic wedge resection for suspected interstitial lung disease. Patients who underwent wedge resection via subxiphoid video-assisted thoracoscopic surgery and conventional video-assisted thoracoscopic surgery were compared. Results: The study included 90 men (59.6%) and 61 women (40.4%) with a mean age of 54.8 ± 12 years. Of these, 127 patients underwent conventional video-assisted thoracoscopic surgery and 24 patients underwent subxiphoid video-assisted thoracoscopic surgery. Postoperative complications occurred in 13 patients (8.6%), with no significant difference according to surgical technique. Sex was a significant factor in the rate of complications (12.2% in men vs. 3.2% in women). There was no intraoperative mortality; the 30-day mortality rate was 4% (n = 6). Five nonsurviving patients were in the conventional video-assisted thoracoscopic surgery group and 1 was in the subxiphoid video-assisted thoracoscopic surgery group (p = 0.95). Conclusion: The results of this study indicate that the subxiphoid approach reduced procedure time and length of hospital stay in the early period, while there was no significant difference between the techniques in terms of complications or mortality. Based on these findings, we conclude that surgical outcomes were as successful with the subxiphoid approach as with conventional video-assisted thoracoscopic surgery. [ABSTRACT FROM AUTHOR]

Background: We investigated whether all size-based pathological T4N0–N1 non-small cell lung cancer patients with tumors at any size >7 cm had the same outcomes. Methods: We reviewed non-small cell lung cancer patients with tumors >7 cm who underwent anatomical lung resection between 2010 and 2016. A total of 251 size-based T4N0–N1 patients were divided into two groups based on tumor size. Group S (n = 192) included patients with tumors of 7.1–9.9 cm and Group L (n = 59) as tumor size ≥10 cm. Results: The mean tumor size was 8.83 ± 1.7 cm (Group S: 8.06 ± 0.6 cm, Group L: 11.3 ± 1.6 cm). There were 146 patients with pathological N0 and 105 patients with pathological N1 disease. Mean overall survival and disease-free survival were 64.2 and 51.4 months, respectively. The five-year overall survival and disease-free survival rates were 51.2% and 43.5% (five-year OS; pT4N0:52.7%, pT4N1:47.9%, DFS; pT4N0:44.3%, pT4N1: 42.3%). No significant differences were observed between T4N0 and T4N1 patients in terms of five-year OS or DFS (p = 0.325, p = 0.505 respectively). The five-year overall survival and disease-free survival rates were 52% and 44.6% in Group S, and 48.5% and 38.9% in Group L. No significant difference was observed between the groups in terms of five-year overall survival or disease-free survival (p = 0.699, p = 0.608, respectively). Conclusions: Above 7 cm, any further increase in tumor size in non-small cell lung cancer patients had no significant effect on survival, confirming it is not necessary to further discriminate among patients with tumors in that size class.

Background Posterior mediastinal lesions are classified as solid lesions and cysts. The treatment for both types is surgery. We evaluated the surgical outcomes and recurrence rates after video-assisted thoracic surgery and thoracotomy for posterior mediastinal lesions. Methods Data of 66 resections for posterior mediastinal masses between 2000 and 2014 were reviewed retrospectively. Twenty-two patients were treated by video-assisted thoracic surgery (group V) and 44 underwent thoracotomy (group T); 29 (43.9%) were female and 37 (56.1%) were male, the mean age was 45.9 ± 14.7 years. Results Bronchogenic cyst was the most common cystic lesion (10/12, 83.3%), and benign schwannoma was the most common solid lesion (32/54, 59.2%). The mean diameter of solid lesions was 5.19 ± 2.4 cm (group V 3.98 ± 1.8 vs. group T 5.78 ± 2.5 cm, p = 0.006). The tumor diameter was 4.06 ± 1.9 cm in asymptomatic patients and 6.93 ± 2.2 cm (p < 0.001) in symptomatic patients. In group V, hospital stay and duration of drainage were significantly shorter than in group T (p = 0.02, p = 0.01). Local recurrence was detected in 4 (6.1%) patients. Cystic lesions had a higher recurrence rate than solid lesions (p = 0.01). There was no significant difference in recurrence rates in groups V and T (p = 0.59). Conclusion Video-assisted thoracic surgery is a safe method for surgical treatment of posterior mediastinal lesions, with a shorter drainage time and postoperative hospitalization and similar recurrence rates. More recurrences are seen in patients with cystic lesions. [ABSTRACT FROM AUTHOR]
