The classification of thymoma has always been controversial topil in recent years. It hasn’t been unified because of the morphological diversity of thymoma, the heterogeneity of tumour cells and the lack of simple and effective observation index. With the development of diagnostic technique and oncobiology research, several classification methods have been drawn off, including its World Health Organization(WHO) lassification. We reviewed the main classification and discussed the problems of each classification method and their clinical guiding significamce, summarized the development tendency, methods assist the classification and clinical research of thymoma.
Lung transplantation has been the only valid method in treating end-stage lung diseases, airway complications are the main cause to the failure of surgery and common postoperative complications. With the development on patient selection, organ preservation, surgical technique, immunosuppressive therapy and postoperative surveillance, the successful ratio of surgery has become most satisfactory. However, airway complications are still common after lung transplantation. Among these, the airway anastomosis stenosis is more predominant than others. The living quality and long-dated survival rate are highly improved by paying enough attention to the formation,corresponding management for tracheal stenosis. The progress of the cause, prevention and treatment of airway anastomosis stenosis after lung transplantation is reviewed in this article.
