The development of surgical and postoperative management techniques has improved the treatment outcomes of esophageal cancer resection. However, respiratory morbidity is still the most frequent complication after esophagectomy. The objective of the present study was to identify risk factors for respiratory complications following resection for esophageal cancer. This study included 96 patients with esophageal cancer who had undergone esophagectomy with lymph node dissection. The patients were divided into 2 groups according to the presence (20 patients, 17 had pneumonia and 3 had acute respiratory distress syndrome) or absence (76 patients) of postoperative respiratory complications (PRC). The two groups were compared with respect to their preoperative clinical variables, such as age, body mass index, smoking history, serum albumin, serum C-reactive protein (CRP), number of lymphocytes, %VC, FEV1.0% and FEV1.0. Furthermore, multiple logistic regression analyses were used to estimate relative risk factors for respiratory complications. Results of the univariate analysis showed that smoking history (+/-, patients with PRC, 19/1 and without PRC, 53/23), serum CRP (≥1.0 mg/dl/
