  • 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.

  • 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.
