Patients And Methods: In this study, a total of 32 NSCLC primary tumor tissues and 32 matching 32 normal tissues were analyzed with Western Blot for CD70, CD27, CD3, and FOXP3; positive and negative results were evaluated according to a quantitative analysis of expression with ImageJ.

Awake versus intubated video-assisted thoracoscopic surgery for pleural disease: a retrospective cohort study from a single tertiary center.

Introduction: Awake video-assisted thoracoscopic surgery (A-VATS) has gained increasing attention as an alternative to classical intubated VATS (I-VATS), particularly in patients with comorbidities that have increased the risk of surgery under general anesthesia. This study aimed to compare the perioperative and postoperative outcomes of patients who underwent A-VATS vs. I-VATS for pleural diseases.

The diagnostic value of thoracic ultrasound in thoracic surgery consultations: a new tool in pleural effusion decision-making.

Introduction: Thoracic ultrasound (US) is a practical tool in radiology that has been commonly used for decades. Its daily clinic use in thoracic surgery is rising, and scientific evidence is needed to support its use.

Aim: We aimed to determine the diagnostic value of handheld, portable thoracic ultrasound scanning (HH-US) in patients referred to the thoracic surgery outpatient clinic with suspected pleural effusion and compare the diagnostic role with chest X-rays (CXR) or computed tomography (CT).

Outcomes of minimally invasive surgery for pulmonary metastasis: who benefits the most?

Introduction: Metastatic disease is one of the main causes of death and factors affecting overall survival. It is known that selected patients with pulmonary oligometastases whose primary tumor is under control and who have adequate respiratory capacity may benefit from metastasectomy by resecting all detected lesions.

Aim: To report our findings on the use of video-assisted thoracoscopic surgery (VATS) for pulmonary metastasectomy, with a focus on identifying suitable candidates.

Prevalence and quantity of lymph nodes at mediastinal stations in patients with lung cancer: lessons from 181 bilateral mediastinal lymphadenectomies.

Background: This study evaluated the prevalence and quantity of lymph nodes at particular stations of the mediastinum in patients with lung cancer. These data are important to radiologists, pathologists, and thoracic surgeons because they can serve as a benchmark when assessing the completeness of lymph node dissection. However, relevant data in the literature are scarce.

The IL-25/ILC2 axis promotes lung cancer with a concomitant accumulation of immune-suppressive cells in tumors in humans and mice.

Background: Group 2 innate lymphoid cells (ILC2) can be activated by interleukin (IL)-33 or IL-25. IL-25-activated ILC2 cells help protect the host against helminth infection while exacerbating allergic-like inflammation and tissue damage in the lung. In the context of cancer, IL-33-activated ILC2 cells were found to bear anti-tumoral functions in lung cancer while IL-25-activated ILC2 cells promoted tumorigenesis in colorectal cancer.

Post bar removal results of pectus deformity patients who underwent minimally invasive correction.

Introduction: The most common chest wall deformities are pectus excavatum and pectus carinatum. Surgical repair of these deformities via minimally invasive technique using pectus bars is commonly preferred by numerous thoracic surgeons. Despite this common choice for treatment, the duration of the bar stay, the bar removal process, the possible complications and ways to prevent them have been debated over the years and still there is no single decision.

Uniportal pure robotic-assisted thoracic surgery-technical aspects, tips and tricks.

The uniportal access for robotic thoracic surgery presents itself as a natural evolution of minimally invasive thoracic surgery (MITS). It was developed by surgeons who pioneered the uniportal video-assisted thoracic surgery (U-VATS) in all its aspects following the same principles of a single incision by using robotic technology. The robotic surgery was initially started as a hybrid procedure with the use of thoracoscopic staplers by the assistant.

Mediastinal lymph node removal modulates natural killer cell exhaustion in patients with non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death globally. In this study, the effect of complete removal of mediastinal lymph nodes by video-assisted mediastinoscopic lymphadenectomy (VAMLA) on natural killer (NK) cell phenotype and functions in patients with NSCLC was evaluated. The study included 21 NSCLC patients (cIA-IVA) undergoing VAMLA staging and 33 healthy controls.

Can postoperative complications be reduced by the application of ERAS protocols in operated non-small cell lung cancer patients?

Background: In our study, we aimed to evaluate the length of hospital stay and complication rate of patients before and after application o f t he E nhanced R ecovery A fter S urgery ( ERAS) protocols.

Methods: Between January 2001 and January 2021, a total of 845 patients (687 males, 158 females; mean age: 55±11 years; range, 19 to 89 years) who were operated with the diagnosis of non-small cell lung carcinoma were retrospectively analyzed. The patients were divided into three groups as follows: patients between 2001 and 2010 were evaluated as pre-ERAS (Group 1, n=285), patients between 2011 and 2015 as preparation for ERAS period (Group 2, n=269), and patients who had resection between 2016 and 2021 as the ERAS period (Group 3, n=291).

A case report of subconjunctival emphysema as a rare complication of pulmonary resections.

Lung volume reduction surgery (LVRS) is performed to the selected patients with lung emphysema who have higher residual volume, restricted pulmonary functions and limited diaphragmatic movement. Post-operative prolonged air leak is not uncommon following LVRS due to pulmonary emphysema. In some patients with prolonged air leak, pneumoderma may develop.

Comparison of uniportal robotic-assisted thoracic surgery pulmonary anatomic resections with multiport robotic-assisted thoracic surgery: a multicenter study of the European experience.

Background: Robotic-assisted thoracic surgery (RATS) has seen increasing interest in the last few years, with most procedures primarily being performed in the conventional multiport manner. Our team has developed a new approach that has the potential to convert surgeons from uniportal video-assisted thoracic surgery (VATS) or open surgery to robotic-assisted surgery, uniportal-RATS (U-RATS). We aimed to evaluate the outcomes of one single incision, uniportal robotic-assisted thoracic surgery (U-RATS) against standard multiport RATS (M-RATS) with regards to safety, feasibility, surgical technique, immediate oncological result, postoperative recovery, and 30-day follow-up morbidity and mortality.

An intrapericardial thymoma resected by uniportal video-assisted thoracoscopic surgery.

Thymomas are usually located in the normal location of the thymus in the anterior mediastinum. It is very rare for thymomas to arise primarily intrapericardially. A 76-year-old male patient with a known human immunodeficiency virus positivity and has been under close follow-up for five years was admitted to our clinic.
