    Background:
    Prediction of postoperative forced expiratory volume in 1 second (FEV1.0) is known as the basis for surgical indications of lung resection. The 0.8L or less estimated postoperative FEV1.0 has been reported an increase in surgery related deaths. In fact, there are some cases that the postoperative FEV1.0 is less than prediction of postoperative FEV1.0. The postoperative respiratory function have been reported in segmentectomy and lobectomy, but little is known in sleeve lobectomy.
    
    Methods:
    Between January 2008 and October 2014, 37 patients underwent sleeve lobectomy and evaluated respiratory function tests of preoperative and passing more than six months after surgery at the Juntendo university, Tokyo, Japan. We defined postoperative FEV1.0 / prediction of postoperative FEV1.0 ratio as postoperative FEV1.0 ratio. The patients were divided by postoperative FEV1.0 ratio into the 16 patients who evaluated postoperative FEV1.0 ratio < 1 and the 21 patients who postoperative FEV1.0 ratio ≧ 1. We investigated clinic-pathological features, postoperative complications and predictive factors in postoperative reduction of FEV1.0.
    
    Results:
    In the group of postoperative FEV1.0 ratio < 1, the median age was 63 years old (range, 35-77 years), 14 cases (88%) were male, the median postoperative FEV1.0 was 2.05L (range, 0.99-2.54) and the median prediction of postoperative FEV1.0 was 1.82L (range, 0.97-2.23). The group of postoperative FEV1.0 ratio < 1 had marginally more phrenic nerve resection (19%) and blood transfusion (50%) than the group of postoperative FEV1.0 ratio ≧ 1 (p=0.077 and p=0.072). There was no difference in the incidence of morbidity between both groups. The phrenic nerve resection was marginally risk factors of postoperative reduction of FEV1.0 in univariate analysis (p =0.053). The phrenic nerve resection and right side were risk factors of postoperative reduction of FEV1.0 in multivariate analysis (p =0.026 and p =0.048).
    
    Conclusion:
    Right side and phrenic nerve resection were independent factors to predict the postoperative FEV1.0 falls below postoperative prediction FEV1.0.
