UNASSIGNED: To assess possible differences in the perioperative profile between men and women in lung cancer surgery.
UNASSIGNED: A prospective cohort multicenter study was design, in which consecutive patients undergoing curative intent surgery for lung cancer in 24 Thoracic Services throughout Spain were included. Clinical features, tumor- and surgery-related data, postoperative complications, and mortality were recorded.
UNASSIGNED: There were 2,566 men and 741 women. Women were younger than men [mean (SD) age, 61.8 (10.8) vs. 66.5 (9.1) years, P<0.0001] and showed a more favorable preoperative characteristics, with significantly higher percentages of ECOG grade 0 and lower percentages of active smokers (28.4% vs. 33.9%; pack-years 18.8 vs. 26.9) and comorbidities [chronic obstructive pulmonary disease (COPD), diabetes, hypertension, cardiac disorders]. There were significant differences (P<0.001) in histological types and TNM stages with adenocarcinoma (70.1% vs. 46.4%) and IA stage (41.5% vs. 33.6%) more frequent in women. The use of VATS or thoracotomy was similar. The rate of pneumonectomy was higher in men (10.9%) than in women (5.1%) (P<0.001) but the distributions of other procedures were similar. Postoperative complications (pneumonitis, atelectasis, air leak, hemorrhage, fistula, empyema, wound dehiscence, and need of reintubation) were lower in women. Significant differences (P<0.0001) in the severity of postoperative complications (Clavien-Dindo classification) were also found, with higher percentages of grades I (51.6% vs. 43%) and II (37.5% vs. 33%) and lower percentages of grades III and IV among women. The mean length of hospital stay was 7.8 (7.1) days in men versus 6.3 (5.0) days in women, and the 30-day mortality rate 0.3% in women versus 2.9% in men (P<0.0001). The percentage of readmissions within 30 days after surgery was also higher in men (8.6% vs. 2.8%).
UNASSIGNED: This multicenter nationwide study of lung cancer surgery with curative intent shows that the perioperative profile is better in women than in men.

OBJECTIVE: Chest drains are used routinely after wedge resection by video-assisted thoracoscopic surgery (VATS), although this practice is based largely on tradition rather than evidence. Chest drains may furthermore cause pain, infections, and prolonged length of stay. The aim of this prospective observational study was to assess the feasibility of avoiding chest drains following VATS wedge resection for pulmonary nodules.
METHODS: Between 1 February and 25 August 2015 166 consecutive patients planned for VATS wedge resection of pulmonary nodules were screened for inclusion using the following criteria: Forced expiratory volume in 1 s (FEV1) ≥60 % of expected, FEV1/forced vital capacity ≥70 %, tumour diameter ≤2 cm, distance from tumour to visceral pleura ≤3 cm, ≤2 separate wedges, no air leak on an intraoperative air leakage test and absence of severe adhesions, bullous/emphysematous disease, pleural effusion and coagulopathy. Chest X-rays were done twice on the day of surgery. 30-day complications were compiled from patient records.
RESULTS: 49 patients underwent 51 unilateral VATS wedge resections without using a post-operative chest drain. No patient required reinsertion of a chest drain. 30 (59 %) patients had a pneumothorax of mean size 12 ± 12 mm on supine 8-h post-operative X-ray for which the majority resolved spontaneously within 2-week control. There were no complications on 30-day follow-up. Median length of stay was 1 day.
CONCLUSIONS: The results support that VATS wedge resection for pulmonary nodules without a post-operative chest drain may be safe in a selected group of patients.

Improving surgical outcomes is important to the thoracic surgical community and operative mortality is often used as a benchmark to gauge the quality of lung resection. In lung cancer surgery, increasing hospital volume is associated with better survival although the categorisation of procedure volume is arbitrary. When US and UK data are scrutinised, the association holds true for increasingly higher volumes up to 150 resection per year and more. The reason may be due to better infrastructure, better-staffed units, more resources and wider specialist and technology-based services in higher volume centers. For individual surgeon volume, reports are not consistent. However, studies suggest that surgeon sub-specialty is an important consideration. The results of general thoracic surgeons and cardiac surgeons are reported to be better than general surgeons for lung resection surgery, and the effects of specialty training was also associated with an increase in the number of patients undergoing lung resection. We conclude that the current evidence strongly supports the association between increasing hospital volume with lower mortality and improved long-term survival following lung resection. Whilst the data presented supports centralization of lung cancer surgery in high volume hospitals, patient choice and the threshold of quality of improvement required to overcome travel and closure of local services need to be considered.

While undergoing an intrapericardial pneumonectomy for a massive right pulmonary inflammatory pseudotumor that had invaded the mediastinum, an 18-year-old woman experienced a nearly fatal iatrogenic complication. Dense scarring adjacent to the pseudotumor had drawn in the superior vena cava posterolaterally and fused the right main pulmonary artery to the right superior pulmonary vein within the pericardium. The failure of a linear stapler to secure the pulmonary vessels led to torrential hemorrhage. Attempts to control the bleeding resulted in inadvertent superior vena cava occlusion and central venous pressure elevation. Because cardiopulmonary bypass might not have been reliably established in time to avoid irreversible cerebral ischemia, we borrowed a technique from congenital heart surgery and rapidly fashioned a cavoatrial connection. The patient survived the operation without negative neurologic or cardiac sequelae, recovered fully, and had no recurrence of the pseudotumor. Herein, we describe the intraoperative decisions that were made under intense time pressure to avert catastrophe.
