Background: Lung transplantation (LTx) is still limited by the shortage of suitable donor lungs. Developing flexible surgical procedures can help to increase the chances of LTx by unfolding recipient-to-donor matching options based on the pre-existing organ allocation concept. We report a case in which a successful left-to-right inverted LTx was completed using the interposition of a pericardial conduit for pulmonary venous anastomosis. Case presentation: A left lung graft was offered to a 59-year-old male who had idiopathic pulmonary fibrosis with predominant damage in the right lung. He had been prescribed bed rest with constant oxygen inhalation through an oxymizer pendant and had been on the waiting list for 20 months. Considering the condition of the patient (LAS 34.3) and the scarcity of domestic organ offers, the patient was highly likely to be incapable of tolerating any additional waiting time for another donor organ if he was unable to accept the presently reported offer of a left lung. Eventually, we decided to transplant the left donor lung into the right thorax of the recipient. Because of the anterior-posterior position gap of the hilar structures, the cuff lengths of the pulmonary veins had to be adjusted. The patient did not develop any anastomotic complications after the transplantation. Conclusions: A left-to-right inverted LTx is technically feasible using an autologous pericardial conduit for pulmonary venous anastomosis in selected cases. This technique provides the potential benefit of resolving challenging situations in which surgeons must deal with a patient’s urgency and the logistical limitations of organ allocation.

Perioperative assessment and care, such as enhanced recovery after surgery (ERAS), is very important for improving the clinical outcomes of patients who have undergone surgery. However, professional assessments and care cannot be achieved through the actions of only 1 surgical department. We established a perioperative management center(PERIO) comprised of surgeons, dedicated nurses, anesthesiologists, dentists, physiotherapists, pharmacists, and nutritionists to perform intensive cross-sectoral perioperative management. In this manuscript, we investigated the impact of PERIO on the clinical outcomes of 127 elderly patients who underwent thoracic surgery for the resection of non-small cell lung cancer (NSCLC). We categorized these 127 patients into 3 groups:① those treated before the introduction of PERIO (between January 2006 to August 2008), ② those treated during the early phase after PERIO introduction (September 2008 to December 2011), and ③ those treated during the late phase after PERIO introduction( January 2012 to December 2014). Radical operations were performed significantly more frequently after PERIO introduction than before PERIO introduction, while the postoperative complication rates were similar among the 3 groups. The duration of postoperative hospitalization was reduced after the introduction of PERIO, and the hospital surplus increased after the introduction of PERIO. In conclusion, PERIO may play an important role in improving the clinical outcomes of thoracic surgery, especially for elderly patients with NSCLC.
