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. Methods: Retrospective cohort study included all R-VATS procedures performed since April 2015 until April 2018. We describe the process of implantation of robotic surgery, highlighting the peculiarities and difficulties found in a developing country. Moreover, we reported our descriptive results and compared the first 60 patients to the subsequent cases. Results: Two hundred and five patients included 101 females/104 males. Mean age was 61.7 years. There were hundred and sixty-four pulmonary resections, 39 resections of mediastinal lesions, 1 diaphragmatic plication, and 1 resection of a hilar tumor. Median operative times were 205 min for lung resections and 129 min for mediastinal. There was no conversion to VATS or thoracotomy or major intraoperative complications. Median length of stay was 3 days for pulmonary resections and 1 day for mediastinal. Postoperative complications occurred in 35 cases (17.0%)—prolonged air leak was the most common (17 cases). One fatality occurred in an elderly patient with pneumonia and sepsis (0.4%). Comparison of the first 60 patients (learning curve) with subsequent 145 patients (consolidated experience) showed significant differences in surgical and ICU time, both favoring consolidated experience. Conclusions: Our results were comparable to the literature. Robotic thoracic surgery can be safely and successfully implemented in tertiary hospitals in emerging countries provided that all stakeholders are involved and compromised with the implementation process.

Objective: The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil. Methods: Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery) were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy. Demographic, surgical, and postoperative data were collected with a standardized instrument, after which they were compiled and analyzed. Results: The surgeons provided data related to a collective total of 786 patients (mean number of resections per surgeon, 43.6). However, 137 patients were excluded because some data were missing. Therefore, the study sample comprised 649 patients. The mean age of the patients was 61.7 years. Of the 649 patients, 295 (45.5%) were male. The majority--521 (89.8%)--had undergone surgery for neoplasia, which was most often classified as stage IA. The median duration of pleural drainage was 3 days, and the median hospital stay was 4 days. Of the 649 procedures evaluated, 598 (91.2%) were lobectomies. Conversion to thoracotomy was necessary in 30 cases (4.6%). Postoperative complications occurred in 124 patients (19.1%), the most common complications being pneumonia, prolonged air leaks, and atelectasis. The 30-day mortality rate was 2.0%, advanced age and diabetes being found to be predictors of mortality. Conclusions: Our analysis of this representative sample of patients undergoing pulmonary resection by video-assisted thoracoscopy in Brazil showed that the procedure is practicable and safe, as well as being comparable to those performed in other countries.

Objective: the study aims to analyze the performance and outcome of resuscitation thoracotomy (TR) performed in patients victims of penetrating and blunt trauma in a trauma center in southern Brazil during a 7 years period., Methods: retrospective study based on the analysis of medical records of patients undergoing TR, from 2014 to 2020, in the emergency service of the Hospital do Trabalhador, Curitiba - Paraná, Brazil., Results: a total of 46 TR were performed during the study period, of which 89.1% were male. The mean age of patients undergoing TR was 34.1±12.94 years (range 16 and 69 years). Penetrating trauma corresponded to the majority of indications with 80.4%, of these 86.5% victims of gunshot wounds and 13.5% victims of knife wounds. On the other hand, only 19.6% undergoing TR were victims of blunt trauma. Regarding the outcome variables, 84.78% of the patients had declared deaths during the procedure, considered non-responders. 15.22% of patients survived after the procedure. 4.35% of patients undergoing TR were discharged from the hospital, 50% of which were victims of blunt trauma., Conclusion: the data obtained in our study are in accordance with the world literature, reinforcing the need for a continuous effort to perform TR, respecting its indications and limitations in patients victims of severe penetrating or blunt trauma.

Objective: To compare two thoracotomy closure techniques (pericostal and transcostal suture) in terms of postoperative pain and pulmonary function., Methods: This was a prospective, randomized, double-blind study carried out in the Department of Thoracic Surgery of the Luzia de Pinho Melo Hospital das Clínicas and at the University of Mogi das Cruzes, both located in the city of Mogi das Cruzes, Brazil. We included 30 patients (18-75 years of age) undergoing posterolateral or anterolateral thoracotomy. The patients were randomized into two groups by the type of thoracotomy closure: pericostal suture (PS; n = 16) and transcostal suture (TS; n = 14). Pain intensity during the immediate and late postoperative periods was assessed by a visual analogic scale and the McGill Pain Questionnaire. Spirometry variables (FEV1, FVC, FEV1/FVC ratio, and PEF) were determined in the preoperative period and on postoperative days 21 and 60., Results: Pain intensity was significantly greater in the PS group than in the TS group. Between the preoperative and postoperative periods, there were decreases in the spirometry variables studied. Those decreases were significant in the PS group but not in the TS group., Conclusions: The patients in the TS group experienced less immediate and late post-thoracotomy pain than did those in the PS group, as well as showing smaller reductions in the spirometry parameters. Therefore, transcostal suture is recommended over pericostal suture as the thoracotomy closure technique of choice.

Objective: Lack of Brazilian publications regarding this disease in Brazil led us to perform the current work to describe the historical evolution and to analyze results of the surgical treatment of Giant Emphysematous Lung Bullae at the Santa Casa de São Paulo., Methods: We have retrospectively assessed, between January 1979 and June 2005, the medical records of 83 patients submitted to one of four surgical modalities: the thoracoscopic bullectomy, VATS bullectomy, VATS bullae drainage and bullae drainage with local anesthesia, totaling 92 surgeries. Parameters analyzed were hospitalization time, post-surgical complications, perioperative and late mortality in addition to clinical and functional pre- and post- surgical parameters., Results: Morbidity was 40.2% and early post-surgical mortality 4.3%. Post-surgical complications were associated to the patient's morbid history. Factors such as diffuse pulmonary emphysema, multiple bullae and age did not influence early complications. There was an improvement in the symptomatology and functional results in 94.5% of the patients. There was no return on he operated bullae. Mortality five years after surgery was of 18.3% and arose, primarily from clinical progression of the diffuse pulmonary emphysema., Conclusions: Several surgical modalities were performed to treat the emphysematous lung bullae, from bullectomy to thoracotomy, at the initial phase until drainage of the bullae with local anesthesia and sprayed talc, the currently preferred modality. Regardless of the method used, however, notwithstanding the relatively high morbidity, post-surgical results are highly favorable with low mortality and uncontestable clinical-functional improvement of the operated patients.

The authors evaluated the usefulness of different trauma indices in the prediction of outcome following penetrating cardiac wounds. Sixty-three patients were retrospectively reviewed. Age, mechanism of injury, Physiologic Index (PI) on admission, site of injury, associated injuries, ISS, RTS, Penetrating Cardiac Trauma Index (PCTI), Penetrating Thoracic Trauma Index (PTTI), Penetrating Trauma Index (PTI), TRISS and mortality rate were reviewed. There were 34 patients with a gunshot wound (GSW) and 29 with a stab wound (SW). Shock was present on admission in 88.9 per cent. Mortality was 83 per cent for GSW, 44 per cent for SW, and 39 per cent for patients arriving the hospital with measurable blood pressure. RTS, PI, PCTI, PTTI, PTI, and ISS reached statistical significance when comparing survivors and nonsurvivors. The probability of survival (PS) based on the TRISS methodology was 37.84 +/- 5.14. The observed survival rate was 38 per cent. Fourteen patients were considered "fatal" on admission and underwent an emergency thoracothomy. Mortality rate for this selected group was 100 per cent. We conclude that physiologic impairment, shock, and GSW are variables with high significance on mortality. Trauma indices such as PI, RTS, PCTI, PTTI, PTI, and ISS are good predictors of outcome. Trauma indices are an important tool to objectively compare results among different institutions.
