Abstract 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. Treatment outcomes and overall survival were analyzed with the Kaplan-Meier method. Results Thirty-seven male patients were included with a median age of 31.8 years. Six presented with synchronous mediastinum and lung metastasis, nine had only lung, and 22 had mediastinal metastasis. Over half had retroperitoneal lymph node metastasis. Twenty-two had dissimilar pathologies, with a discordance rate of 62 %. Teratoma and embryonal carcinoma were the prevalent primary tumor types, 40.5 % each, while teratoma was predominant (70.3 %) in the metastasis group. Thoracotomy was the main surgical approach (39.2 %) followed by VATS (37.2 %), cervico-sternotomy (9.8 %), sternotomy (5.8 %), and clamshell (3.9 %). Lung resection was performed in 40.5 % of cases. Overall, 10-year survival rates were 94.3 % with no surgical-related mortality. Conclusion Multimodality treatment with systemic therapy followed by radical surgery offers a high cure rate to patients with intrathoracic metastatic testicular germ cell tumors. 2 NonSeminomatous Non Seminomatous (NSGCT chemotherapy longterm long term 201 2022 KaplanMeier Kaplan Meier method Thirtyseven Thirty seven 318 31 8 31. years Twentytwo Twenty two pathologies 6 types 405 40 5 40. each 70.3 703 70 3 (70. group 39.2 392 39 (39. 37.2 372 37 (37. %, , cervicosternotomy cervico 9.8 98 9 (9. 5.8 58 (5. 3.9 (3. . cases Overall 10year year 10 943 94 94. surgicalrelated related mortality tumors 202 4 70. 7 (70 39.

Abstract Objective: This study aims to correlate the RAPID score with the 3-month survival and surgical results of patients undergoing lung decortication with stage III pleural empyema. Methods: This was a retrospective study with the population of patients with pleural empyema who underwent pulmonary decortication between January 2019 and June 2022. Data were collected from the institution’s database, and patients were classified as low, medium, and high risk according to the RAPID score. The primary outcome was 3-month mortality. Secondary outcomes were the length of hospital stay, readmission rate, and the need for pleural re-intervention. Results: Of the 34 patients with pleural empyema, according to the RAPID score, patients were stratified into low risk (23.5 %), medium risk (47.1 %), and high risk (29.4 %). The high-risk group had a 3-month mortality of 40 %, while the moderate-risk group hada 6.25 % and the low-risk group had no deaths within 90days, confirmingagood correlation with the RAPID score (p < 0.05). Sensitivity and specificity for the primary outcome in the high-risk score were 80.0 % and 79.3%, respectively. The secondary outcomes did not reach statistical significance. Conclusions: In this retrospective series, the RAPID score had a good correlation with 3-month mortality in patients undergoing lung decortication. The morbidity indicators did not reach statistical significance. The present data justifies further studies to explore the capacity of the RAPID score to be used as a selection tool for treatment modality in patients with stage III pleural empyema.

Abstract Background and objective This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects. Materials and methods The authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023. Results 463 chest tube insertions and 200 thoracenteses were performed during the study period. Most procedures were conducted by 1st-year Thoracic Surgery residents, with Ultrasound Guidance (USG). There was a notable preference for small-bore pigtail catheters, with a low rate of immediate complications. Conclusion Bedside thoracic procedures are commonly performed in current medical practice and are significant in surgical resident training. The utilization of pigtail catheters and point-of-care ultrasonography by surgical residents in pleural procedures is increasingly prevalent and demonstrates high safety. aspects 202 2023 46 20 period 1styear styear 1st year st USG.

ABSTRACT Objective: This study aims to evaluate the role of TUSG in the postoperative period and the detection of early complications after surgical treatment, pulmonary resection, or decortication for infectious and inflammatory thoracic diseases, comparing with the standard method (Chest Radiography ‒ CXR). Methods: Prospective non-randomized self-controlled study. Twenty-one patients over 16 years of age have undergone surgical treatment of inflammatory and infectious lung diseases. These patients were followed up with CXR and TUSG (performed on the 1st and 3rd postoperative days and/or after the chest tube removal). Results: Both exams demonstrated similar results regarding their ability to safely predict the adequate moment for chest drain removal. TUSG allowed chest drain removal in 30% of cases and CXR in 34%. Statistical analysis demonstrates that both exams have similar capabilities in detecting postoperative changes in the pleural space. However, the authors report that TUSG is statistically more accurate in detecting subcutaneous emphysema than CXR (p = 0.037, Kappa [κ = 0.3068]). The analysis of other parameters showed no statistical difference. Conclusion: The authors conclude that TUSG in trained hands is equivalent to CXR in searching for postoperative complications regarding the surgical treatment of infectious and inflammatory thoracic diseases and can be used as a complement, and not a substitute, to CXR, when CCT is not feasible, or a more urgent diagnosis is needed.

Abstract Objective: Identify the one-year survival rate and major complications in patients submitted to pneumonectomy for infectious disease. Methods: Retrospective data from all cases of infectious disease pneumonectomy over the past 10 years were collected from two reference centers. The authors analyzed: patient demographics, etiology, laterality, bronchial stump treatment, presence of previous pulmonary resection, postoperative complications in the first 30 days, the treatment used in pleural complications, and one-year survival rate. Results: 56 procedures were performed. The average age was 44 years, with female predominance (55%). 29 cases were operated on the left side (51%) and the most frequent etiology was post-tuberculosis (51.8%). The overall incidence of complications was 28.6% and the most common was empyema (19.2%). Among empyema cases, 36.3% required pleurostomy, 27.3% required pleuroscopy and 36.3% underwent thoracoplasty for treatment. Bronchial stump fistula was observed in 10.7% of cases. From all cases, 16.1% were completion pneumonectomies and 62.5% of these had some complication, a significantly higher incidence than patients without previous surgery (p = 0.0187). 30-day in-hospital mortality was (7.1%) with 52 cases (92.9%) and 1-year survival. The causes of death were massive postoperative bleeding (1 case) and sepsis (3 cases). Conclusions: Pneumonectomy for benign disease is a high-risk procedure performed for a variety of indications. While morbidity is often significant, once the perioperative risk has passed, the one-year survival rate can be very satisfying in selected patients with benign disease.

ABSTRACT Bronchial anastomotic complications are a cause of grave concern for surgeons that perform lung transplantations. There are several risk factors that may lead to this complication, being inadequate surgical technique one of them, specifically regarding adequate exposure and manipulation of the bronchial stump and anastomosis. Here we report the use of Octopus™ Tissue Stabilizer as a mean to allow for a better exposure of the stump and facilitate a “no-touch” approach towards anastomosis. Systematic application of devices that facilitate the employment of the correct surgical techniques can have an effect in reducing the incidence of bronchial anastomotic complications. transplantations complication them anastomosis Octopus notouch no touch “no-touch
