Background: Chest wall tumors are uncommon. The surgical objective is local disease control and the relief of symptoms. Due to the heterogeneity of cases, the great variety of reconstructions, size of resection, and clinical and surgical outcomes are still uncertain.

- Sternal cleft (SC) is a rare birth defect characterized by a lack of fusion in the sternum, leading to abnormal midline movement, and can be detected before or after birth through imaging methods.
- SC is categorized into complete (full gap between sternal bars) and incomplete (superior or inferior gaps), with surgery recommended primarily for newborns due to their flexible chests which lowers the risk of complications.
- The text discusses various surgical techniques and materials used for repair, highlights challenges faced during surgery, and presents proposed modifications to improve the surgical process.
Introduction: Almost 20 % of patients with Non-Seminomatous Germinative Cell Tumors (NSGCT) will require intrathoracic metastasectomy after chemotherapy. The authors aim to determine their long-term survival rates.
Methods: Retrospective study including patients with NSGCT and intrathoracic metastasis after systemic therapy from January 2011 to June 2022.
Article Synopsis
- The study aimed to identify risk factors for developing empyema after talc slurry pleurodesis in patients with malignant pleural effusion to improve patient selection and reduce complications.
- Among 86 analyzed patients, 23.3% developed empyema, with significant risk factors identified as prolonged pleural drainage and prior antibiotic use.
- The findings suggest avoiding antibiotic therapy before the procedure and exercising caution with patients who have extended chest tube durations or incomplete lung expansion, as they may have a higher risk of complications.
Objective: To compare 90-day morbidity in patients undergoing lung lobectomy performed by either robotic-assisted thoracic surgery (RATS) or video-assisted thoracic surgery (VATS). Intraoperative complications, drainage time, length of hospital stay, postoperative pain, postoperative quality of life, and readmissions within 90 days were also compared.
Methods: This was a two-arm randomized clinical trial including patients with lung lesions (primary lung cancer or lung metastasis) who were candidates for lung lobectomy.
Objective: in Latin America, especially Brazil, the use of a robotic platform for thoracic surgery is gradually increasing in recent years. However, despite tuberculosis and inflammatory pulmonary diseases are endemic in our country, there is a lack of studies describing the results of robotic surgical treatment of bronchiectasis. This study aims to evaluate the surgical outcomes of robotic surgery for inflammatory and infective diseases by determining the extent of resection, postoperative complications, operative time, and length of hospital stay.

However, only a subset of patients derives clinical benefits. Although programmed death-ligand 1 (PD-L1) and tumor mutational burden (TMB) are known to be prognostic and demonstrated utility in selecting patients for immunotherapy response, they are imperfect biomarkers.
View Article and Find Full Text PDFObjective: To describe the morbidity, mortality, and rate of complete resection associated with robotic surgery for the treatment of non-small cell lung cancer in Brazil, as well as to report the rates of overall survival and disease-free survival in patients so treated.
Methods: This was a retrospective study of patients diagnosed with non-small cell lung carcinoma and undergoing resection by robotic surgery at one of six hospitals in Brazil between February of 2015 and July of 2018. Data were collected retrospectively from the electronic medical records.
Objective: to report our initial experience with pulmonary robotic segmentectomy, describing the surgical technique, the preferred positioning of portals, initial results and outcomes.
Methods: we collected data, from a prospective robotic surgery database, on patients undergoing robotic segmentectomy between January 2017 and December 2018. All patients had lung cancer, primary or secondary, or benign diseases, and were operated on with the Da Vinci system, by the three portals technique plus one utilitarian incision of 3cm.
Background: In the last decade, robotic video-assisted thoracic surgery (R-VATS) has grown significantly and consolidated as an alternative to video-assisted thoracic surgery. The objective of this study is to present the implementation as well as the experience with R-VATS accumulated by 2 Brazilian groups. We also compared the outcomes of procedures performed during the learning curve and after a more mature experience.
View Article and Find Full Text PDFObjectives: The objective of this study is to describe the experience of a Brazilian public university hospital regarding the treatment of metastatic or benign spine lesions with en bloc vertebrectomy of the thoracic and lumbar spines.
Methods: This study was a retrospective case series and included all medical records of patients with benign aggressive, primary malignant, or metastatic spine lesions who underwent en bloc vertebrectomy from 2010 to 2015.
Results: A total of 17 patients were included in the analysis.
Ultrasound-guided intrapleural positioning of pleural catheters: influence on immediate lung expansion and pleurodesis in patients with recurrent malignant pleural effusion.
J Bras Pneumol
September 2017
Objective:: To evaluate the role of intrapleural positioning of a pleural catheter in early lung expansion and pleurodesis success in patients with recurrent malignant pleural effusion (RMPE).
Methods:: This was a retrospective study nested into a larger prospective cohort study including patients with RMPE recruited from a tertiary university teaching hospital between June of 2009 and September of 2014. The patients underwent pleural catheter insertion followed by bedside pleurodesis.
Objective: To describe the implementation of a robotic thoracic surgery program at a public tertiary teaching hospital and to analyze its initial results.
Methods: This was a planned interim analysis of a randomized clinical trial aimed at comparing video-assisted thoracoscopic surgery and robotic surgery in terms of the results obtained after pulmonary lobectomy. The robotic surgery program developed at the Instituto do Câncer do Estado de São Paulo, in the city of São Paulo, Brazil, is a multidisciplinary initiative involving various surgical specialties, as well as anesthesiology, nursing, and clinical engineering teams.
