Selection of pulmonary resection procedures to reduce postoperative complications in 200 patients.

PURPOSE

We previously demonstrated in a pilot study that postoperative cardiopulmonary complications could be reduced by selecting pulmonary resection procedures based on the results of a combination of specific preoperative cardiopulmonary function tests. The present study reports a re-examination of the criteria for preoperative screening and prospectively assessed whether the selected surgical procedures were appropriate in 200 patients who underwent the planned extent of pulmonary resection.

METHODS

In 200 patients requiring lung tumor resection, five preoperative parameters (forced expiratory volume in 1 s on the intact side, maximal oxygen uptake, ejection fraction, occluded pulmonary artery pressure, and occluded total pulmonary vascular resistance index) were used to assign each patient to one of five risk categories in order to select the optimal resection procedure. Thereafter, the postoperative course was investigated to determine the value of this selection method.

RESULTS

Thoracotomy was performed in 195 of the 200 patients (97.5%). Two patients (1%) died; one patient succumbed to acute exacerbation of interstitial pneumonia and the other patient died from pulmonary embolism. Six patients (3.1%) developed major complications after surgery and 12 patients (6.2%) had mild complications, while 175 (89.7%) showed a good postoperative course.

CONCLUSION

The use of five preoperative parameters to select the pulmonary resection procedure minimized postoperative death and major complications.
