Patient selection, surgery and perioperative management in lung transplantation in Japan.

Lung transplantation (LT) is the final treatment option for end-stage respiratory diseases. The current prognosis of LT recipients in Japan is good, however, the reason for the good prognosis is unclear. In Japan, the waiting time for cadaveric LT is long, which is approximately 900 days on average. A long waiting time affects several aspects of LT. The diseases progress while they await LT in most patients are waiting for LT. Along with the disease progression of the disease, secondary pulmonary hypertension can newly emerge. Some patients suffer from refractory secondary pneumothorax and may receive pleurodesis. Transplant operations can become more difficult, and postoperative management becomes more complicated owing to the disease progression. Thoracic surgeons in Japan have managed the tough difficult situation of LT patients with LT. Possible explanations for how we to maintain a better prognosis in such a situation include sophisticated surgical techniques and ideas, and vigorous postoperative management by thoracic surgeons. Thoracic surgeons are vigorously involved both in operations and in postoperative management in the intensive care unit with or without intensivists in Japan. On the other hand, the long waiting time in Japan and allocation rules with age restriction without considering the severity of patients may have resulted in the selection of recipients to include relatively young recipients, fewer patients with interstitial lung disease and fewer recipients with extracorporeal membrane oxygenation (ECMO) as a bridge to LT. These recipients' characteristics possibly may have affected the prognosis of LT patients with LT in Japan. There is a chance that a future increase in the number of cadaveric donors in Japan may result in a prognosis close that is similar to the international average if the current waiting time in Japan decreases. We review patient selection, surgery and perioperative management in LT in Japan to address the question of why the current prognosis of LT recipients in Japan is good.
