Objectives: Fibrinolytic therapy can be effective for management of complex pleural effusions. Tissue plasminogen activator (tPA, 10 mg) and deoxyribonuclease (DNAse) every 12 h with a dwell time of one hour is a common strategy based on published data. We used a simpler protocol of tPA (4 mg) without DNAse but with a longer dwell time of 12 h, repeated daily.

Objectives: Shortening hospital length of stay after lobectomy for stage I non-small-cell lung cancer (NSCLC) remains a challenge, and the literature regarding factors associated with safe early discharge is limited. We sought to evaluate the safety of postoperative day (POD) 1 discharge after lobectomy and its correlation with institutional caseload using the National Cancer Database, jointly sponsored by the American College of Surgeons and the American Cancer Society.

Methods: We identified patients with stage I NSCLC (tumour ≤4 cm, clinical N0, M0) in the National Cancer Database who underwent lobectomy from 2010 to 2015.

Objective Talc slurry pleurodesis (TSP) can lead to permanent small loculations. Intrapleural tissue plasminogen activator (tPA) breaks down loculations, and therefore may improve results but may also inhibit pleurodesis. tPA was given with and after talc slurry to promote more uniform talc distribution and eliminate loculations.

Introduction Published trials of intrapleural therapy for complex pleural effusions rely on fibrinolytics and deoxyribonuclease (DNase) with dwell times of less than six hours and frequent dosing. We reviewed our experience with fibrinolytics alone but with a longer dwell time (12 hours). Methods Tissue plasminogen activator (tPA, 1-6 mg per dose) was given through pigtail catheters placed using image guidance.

Purpose: We examined the relationship between short-term outcomes and hospitals and surgeons who met minimum volume thresholds for lung cancer resection based on definitions provided by the Volume Pledge. A secondary aim was to evaluate the volume-outcome relationship to determine alternative thresholds in the event the Volume Pledge was not associated with outcomes.

Patients And Methods: We conducted a retrospective study (2015-2017) using the Society of Thoracic Surgeons General Thoracic Surgery Database.

Lung cancer is the deadliest cancer worldwide and is of particular concern for Latin America. Its rising incidence in this area of the world poses myriad challenges for the region's economies, which are already struggling with limited resources to meet the health care needs of low- and middle-income populations. In this environment, we are concerned that regional governments are relatively unaware of the pressing need to implement effective strategies for the near future.

The outcomes research efforts based on The Society of Thoracic Surgeons (STS) General Thoracic Surgery Database include two established research programs with dedicated task forces and with data analyses conducted at the STS data analytic center: (1) The STS-sponsored research by the Access and Publications program, and (2) grant and institutionally funded research by the Longitudinal Follow-Up and Linked Registries Task Force. Also, the STS recently introduced the research program enabling investigative teams to apply for access to deidentified patient-level General Thoracic Surgery Database data sets and conduct related analyses at their own institution. Last year's General Thoracic Surgery Database-based research publications and the new Participant User File research program are reviewed.

Background: Data from selected centers show that robotic lobectomy is safe and effective and has 30-day mortality comparable to that of video-assisted thoracoscopic surgery (VATS). However, widespread adoption of robotic lobectomy is controversial. We used The Society of Thoracic Surgeons General Thoracic Surgery (STS-GTS) Database to evaluate quality metrics for these 2 minimally invasive lobectomy techniques.

Accurate mediastinal staging is essential to determining the optimal therapeutic strategy for many patients with lung cancer. Computed tomography and positron emission tomography are first steps, but frequently tissue sampling is recommended to confirm the radiographic findings. Mediastinoscopy has been the gold standard for thirty years, but the new technologies of esophageal endoscopic ultrasound and endobronchial ultrasound provide a less invasive method for biopsy.

Background: No guidelines exist regarding the number of mediastinal lymph node stations that should be sampled to ensure adequate preoperative staging of lung cancer patients. In recent reports of esophageal endoscopic ultrasound and endobronchial ultrasound (EBUS), fewer than two stations/patient were sampled. An experience with systematic sampling using EBUS to determine how many stations should be sampled to adequately detect mediastinal disease was evaluated.

Background: Esophageal endoscopic ultrasound (EUS) and endobronchial ultrasound (EBUS) are gaining popularity for mediastinal staging of patients with lung cancer. Endoscopic ultrasound and then EBUS were introduced into a single-surgeon thoracic surgical practice. Records were reviewed to determine what effect this had on performance of mediastinoscopy for lung cancer staging, and on discovery of unsuspected N2 disease at the time of resection.

Background: Media reports of ethical transgressions in research with human subjects have increasingly focused attention on clinical investigators and have served to undermine public confidence in medical research. A series of editorials in The Annals of Thoracic Surgery and The Journal of Thoracic and Cardiovascular Surgery in 2002 and 2003 emphasized integrity in research publication. We investigated the extent to which the ethical process was mentioned in reports of thoracic surgical research with human subjects since 2002.

Chronic aspiration is a difficult and potentially lethal problem. Patients who have persistent soilage of the upper respiratory tract despite discontinuing oral intake may be offered surgical intervention to avoid life-threatening pulmonary infections. The Lindeman procedures (tracheoesophageal diversion and laryngotracheal separation) have gained popularity as surgical treatments for intractable aspiration because of their efficacy in preventing aspiration and their technical simplicity.
