title: [Comparing the therapeutic effect of lung transplantation with the therapeutic effect of whole lung lavage for the patients with end-stage pneumoconiosis].
abstract: OBJECTIVE
  To explore the therapeutic effects of lung transplantation (LTx) and whole lung lavage (WLL) for patients with end-stage pneumoconiosis.
  
  
  METHODS
  From June 2002 to February 2011, 5 cases with end-stage pneumoconiosis were treated with LTx and 12 cases with end-stage pneumoconiosis were treated with WLL. The clinical symptoms, pulmonary functions, pulmonary artery pressures, blood gas analysis, imagings of chest and survival status were retrospectively analyzed.
  
  
  RESULTS
  In LTx group, the clinical symptoms (cough, sense of suppression in the chest), pulmonary functions and blood gas indicators were improved, pulmonary artery pressures decreased to normal levels, the imaging of chest showed that the implanted lung inflated well and was with clear lung markings. But the contralateral lungs without treatment appeared the progression of disease in the imaging of chest. In WLL group, the clinical symptoms in a half year after treatment were improved but the symptomatic relief rate declined with time, the pulmonary functions in half year after treatment were improved but decreased after 2 years, the pulmonary artery hypertension enhanced generally, as compared with that prior to WLL. The disease progression in the chest imaging examination was not found in a half year after WLL, but appeared in 1 ∼ 2 years after WLL. During following-up. the mean survival times in LTx and WLL groups were 40.5 and 21.4 months, respectively. In LTx group, one patient died of multiple organ dysfunctions (MODS) caused by primary graft dysfunction (PGD), one case died of severe infection in seven months after LTx. Up to now, other 3 cases have survived for 65, 41 and 29 months, respectively. In WLL group, 3 cases died of pulmonary infection, 2 cases died of respiratory failure, one case died of heart failure and one case died of encephalon vascular accident, the mean survival time of these 7 patients was (19.0 ± 8.7) months. So far other 5 cases have survived for 7, 9, 13, 18 and 26 months, respectively.
  
  
  CONCLUSIONS
  LTx has greater risk of death during preoperative period, but patients after LTx may have long survival times with good quality of life. The clinical symptoms and pulmonary functions of patients can be improved temporarily after WLL, but the survival time of WLL is inferior to that of LTx.
