PREOPERATIVE ASSESSMENT FOR THE RISK OF POSTOPERATIVE PULMONARY COMPLICATIONS IN PATIENTS WITH ESOPHAGEAL CANCER
Retrospective study was carried out to assess pulmonary complications in 50 patients with esophageal cancer who underwent esophagectomy over the last 5 years. Spirometrical parameters such as V
25 and V
50/V
25, which reflect small air way closure of the lung, were studied preoperatively and compared with the incidence of postoperative expectoration disorders such as atelectasis and/or pneumonia. All patients developed the pulmonary complications after the operation in following conditions : 1) V
25<0.3 l/sec and V
50/V
25>4 in patients without thoracotomy ; 2) V
25<1.0l/sec and V
50/V
25>3 in patients with thoracotomy ; 3) V
25<1.0 l/sec and V
50V
25<3 with closed pattern of the V-V curve in patients with thoracotomy.
Although the causes of postoperative pulmonary complications are multifactorial, the preoperative values of V
25 and V
50/V
25 are considered to be useful indices to decide the optimal operative procedure and predict the postoperative pulmonary complications.
