  • COVID-19 after lung transplantation: Four case reports

    From December 2022 to January 2023, 4 lung transplant recipients (3 males and 1 female, aged 52-60 years, all received transplantation less than 1 year) were hospitalized in the Department of Thoracic Surgery of the First Affiliated Hospital of Xi'an Jiaotong University due to COVID-19 after surgery. The clinical manifestations were mostly characterized by elevated body temperature accompanied by shortness of breath, and indicators such as heart rate, oxygen saturation, and oxygenation index could reflect the severity of the condition. The therapy was timely adjusted to immunosuppressive drugs, upgraded oxygen therapy, anti-bacterial and anti-fungal therapy, prone ventilation, general treatment, and anticoagulant therapy, depending on the situation. Finally, 3 patients were cured and discharged from hospital, and 1 died.

  • Thoracic surgery perspective of comprehensive treatment of esophageal cancer with esophagus preserved

    Surgery is a classic traditional method for the treatment of early-stage esophageal cancer, and it is also recognized as an effective first-choice method in the medical community. With the development of endoscopic technology, esophagus-preserving comprehensive treatment of esophageal cancer has almost the same or even better effects in some aspects in the treatment of early esophageal cancer than surgery. Many clinical guidelines have also recommended it as the first-choice treatment for early esophageal cancer. The room for surgical treatment of esophageal cancer has been further compressed. This article discusses the comprehensive treatment model of esophageal cancer from the perspective of thoracic surgery, aiming to find a new position of thoracic surgery in the treatment of esophageal cancer.

  • Short-term efficacy and safety of pembrolizumab combined with neoadjuvant chemotherapy for the treatment of non-small cell lung cancer

    ObjectiveTo explore the short-term efficacy and safety of pembrolizumab combined with chemotherapy in the neoadjuvant treatment of non-small cell lung cancer. MethodsThe clinical data of 11 male patients with non-small cell lung cancer who underwent pembrolizumab combined with neoadjuvant chemotherapy in the Department of Thoracic Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from December 2019 to June 2021 were retrospectively analyzed. The average age of the patients was 52.0-79.0 (62.0±6.9) years. The imaging data and pathological changes before and after neoadjuvant treatment were compared, and adverse reactions during neoadjuvant treatment were recorded. Objective remission rate (ORR) and main pathological remission rate (MPR) and pathological complete remission rate (pCR) were the main observation endpoints. ResultsAfter preoperative neoadjuvant therapy with pembrolizumab combined with platinum or paclitaxel, all patients successfully underwent thoracoscopic radical resection of lung cancer. The ORR was 72.7%, and the MPR was 81.8%. Among them, 45.5% of patients achieved pCR. The main adverse reactions were hypoalbuminemia, decreased appetite and nausea. The mortality rate within 30 days after surgery was 0, and no tumor metastasis was observed. ConclusionPembrolizumab combined with neoadjuvant chemotherapy is safe and feasible to treat non-small cell lung cancer, and the short-term efficacy is beneficial.

  • Experimental study on the method of establishing a pig left lung orthotopic transplantation model

    ObjectiveTo explore the method for establishing a pig left lung orthotopic transplantation model. MethodsDetailed surgical procedures, including animal anesthesia, tracheal intubation, donor lung retrieval, and recipient transplantation, were thoroughly reported. By examining the histological morphology and blood gas analysis of the transplanted lung 2 hours after reperfusion, the histological changes and function of the transplanted lung were assessed. ResultsThis method was applied to four male Yorkshire pigs with an average weight of (40 ±2.50) kg for left lung in situ transplantation, effectively simulating conditions relevant to human lung transplantation. Two hours post-transplantation, arterial blood gas analysis showed PaO2 values ranging from 155.4 to 178.6 mmHg, PaCO2 values ranging from 53.1 to 62.4 mmHg, and PaO2/FiO2 ratios ranging from 310.8 to 357.2 mmHg. Hematoxylin and eosin (H&E) staining indicated a low degree of pulmonary edema and minimal cellular infiltration. ConclusionsThe pig left lung orthotopic transplantation model possesses strong operability and stability. Researchers can replicate this model according to the described methods and further conduct basic research and explore clinical translational applications.
