PURPOSE: Pulmonary complications after esophagectomy are still common and are a major cause of mortality. The aim of this study was to clarify the risk factors for the occurrence of pulmonary complications after esophagectomy. METHODS: The clinical courses of 299 patients who underwent elective subtotal esophagectomy with lymph node dissection for esophageal cancer were retrospectively analyzed. Group I included patients who had pulmonary complications (n = 53), and group II included patients who did not (n = 246). The clinicopathological factors, surgical procedures and surgical results were compared between the groups. RESULTS: The frequency of any pulmonary complication was 17.7 %. Pneumonia (n = 26; 8.7 %) and respiratory failure that needed initial ventilatory support for 48 h or reintubation (n = 16; 5.4 %) were the major morbidities. The results of the logistic regression analysis suggested that smoking with a Brinkman index ≥800, salvage esophagectomy after definitive chemoradiotherapy and the amount of blood loss/body weight were independent factors associated with the occurrence of pulmonary complications. CONCLUSION: Pulmonary complications after esophagectomy remain common despite advances in perioperative management. Cases with a history of heavy smoking, preoperative definitive chemoradiotherapy, and high blood loss during surgery require more careful postoperative pulmonary care.
