[Respiratory function evaluation in esophageal surgery. Predictive value of tests].

In the context of major surgery the predictive significance of respiratory function tests in relation to postoperative pleuro-pulmonary complications is assessed. A statistical analysis is performed on a series of 85 oesophagectomy after thoracotomy and laparotomy. The most significant respiratory function indices are found to be those relating to volume restriction and the Mottley index.
