[Analysis of postoperative pulmonary complications after esophagectomy for esophageal cancer].

We examined factors contributing to an onset of postoperative pulmonary complications following esophagectomy for esophagus cancer. One hundred thirty-two cases of the resected esophageal cancer were studied. We considered the relationship between preoperative patient factors, operative factors, clinical stage factors and postoperative pulmonary complications. Postoperative pulmonary complication was observed in 27 cases (20%). The incidence of postoperative pulmonary complications was significantly higher in patients aged 70 and above and those with a preoperative serum albumin value of less than 4 .0 g/dL. Additionally, these two factors were correlated with an onset of postoperative pulmonary complications in multivariate analyses. A decrease of preoperative serum albumin value was reflecting the chronic poor nutritional condition. Moreover, it was possible that poor nutritional condition served as a prognostic factor of postoperative complications in relation to reduction of cellular immunity. The results indicated that there was a possibility of decreasing an onset of postoperative pulmonary complications using various nutrition managements before operations.
