Thoracic surgery in Brazil: an overview.

Brazil is an emerging country with continental proportions, being one of the largest in the world. As big as its territory, are the complexities and singularities within it. Brazilian thoracic surgery reflects the picture of this unique giant, with all its virtues and problems. This peculiar framework of thoracic surgery in Brazil unfolds that the surgeons are usually well trained and can perform this specialty with technical and scientific excellence, making the country to play a true major role in Latin American thoracic surgery. Nevertheless, the chronic social imbalance present in every aspect of the Brazilian daily life hampers this ultra-specialized workforce to be equally and universally available for every citizen, in every corner of the country. Lung transplantation and minimally invasive approaches (including robotics) are performed by many surgeons with good results, comparable to those observed in high-income countries from North America, Europe and Asia. However, these procedures are still performed more often in centers of academic excellence, located at the main cities of the country, which also reflects an unequal access to these approaches within the Brazilian territory. The aim of this paper is to present a broad overview of the practice of general thoracic surgery in Brazil, as well as its main idiosyncrasies.

Tracheal Diverticulum as a Cause of Recurrent Infection in Post-Lung Transplant Patients: A Report of 2 Cases.

BACKGROUND: Tracheal diverticulum (TD) is a rare entity in clinical practice, accidentally found by imaging methods. It is a potential factor for the development of chronic respiratory infections, contributing to the progression of preexisting lung diseases and putting the success of lung transplantation at risk. OBJECTIVES: This paper reports 2 cases of TD with atypical clinical presentation in post-lung transplant patients with recurrent infections and aims to present the importance of this differential diagnosis. DISCUSSION: Case 1: A 30-year-old man with terminal lung disease underwent bilateral lung transplantation with a satisfactory postoperative period. He presented with TD as a focus of recurrent infection associated with persistent hemoptysis. Indicated for surgical resection (cervicotomy with resection of tracheal diverticulum), without complications. He evolved uneventfully in the postoperative period and was clinically stable at follow-up. Case 2: A 57-year-old woman with hypersensitivity pneumonia associated with secondary pulmonary arterial hypertension and bronchiectasis underwent bilateral lung transplantation without complications. She presented with TD as a focus of infection associated with esophageal symptoms. Indicated for the surgical approach (cervicotomy with resection of tracheal diverticulum), she was asymptomatic at follow-up. CONCLUSION: Conservative treatment is recommended in elderly and asymptomatic patients. Surgical resection is based on the recurrence of symptoms and failure of clinical therapy and is the preferred approach for reported cases.

Chronic Pain After Lung Transplantation and Its Impact on Quality of Life: A 4-Year Follow-up.

Aiming to investigate the prevalence of chronic pain and its impact on quality of life of lung transplantation (LTx) recipients, we performed a transversal study collecting data using a standard interview model in 2 different periods: first, in 2016 we studied LTx recipients after 3 to 11 months of the transplantation; and second, in 2019, we studied the same patients after 39 to 55 months of transplantation surgery. The chosen questionnaires were the Brief Pain Inventory and Short-Form Health Survey. Chronic pain was identified in 47.2% of the analyzed recipients at the initial interview and in 40.7% at the second evaluation. In both periods, the domain quality of life was the most affected in contrast to functional capacity, which was the least affected. On the first analysis, a moderate negative correlation was found between pain intensity and functional capacity domains (-0,42/P = .010), pain (-0,46/P = .005), and mental health (-047/P = .004); meanwhile, the second survey showed a moderate/high negative correlation for most of the domains, except for the mental health (-0,036/P = .120). We conclude that the prevalence of chronic pain after LTx is high, and the pain intensity had a moderate negative correlation with domains such functional capacity, mental health, and pain at the first analysis in contrast to the moderate/high negative correlation for almost every domain, except mental health, at the second analysis.

Technical Challenges in Lung Transplantation of Kartagener Syndrome Recipients: A Unique Team Experience With 12 Patients.

Kartagener syndrome (KS) is a rare congenital disorder related to bronchiectasis, chronic sinusitis, and situs inversus, predisposing patients to recurrent respiratory infections that can evolve to end-stage lung disease; lung transplantation (LTx) is one of the therapeutic options. This study highlights some concerns in this group of patients, mainly related to the difficulty of performing the transplantation in recipients with suppurative disease and situs inversus. We conducted a retrospective analysis of all KS patients who underwent LTx at 2 national reference centers by the same LTx team. During 29 years of analysis, we performed 12 cases of bilateral sequential LTx in KS patients, representing 2.4% of all Ltx that we performed. Special perioperative care is needed, including vascular access sites and lung isolation techniques; operative concerns include the arteriotomy and bronchotomy during the back table preparation of the graft and concern about the length of the arterial and bronchial anastomosis. We found a higher incidence of bronchial complications is this group that had not been previously reported. Bilateral sequential orthotopic LTx is feasible in this group of patients, and more studies are needed to understand possible reasons for the apparent higher incidence of bronchial complications.
