Comparison between quantitative computed tomography, scintigraphy, and anatomical methods for prediction of postoperative FEV₁ and DLCO: effects of chronic obstructive pulmonary disease status and resected lobes.

ABSTRACT:

Background

Postoperative assessment of pulmonary function is important for estimating the risk of thoracic surgery and long-term disability following pulmonary resection, including predicted postoperative (ppo) forced expiratory volume (FEV) in one second (ppoFEV₁) and percent predicted lung diffusion capacity for carbon monoxide (ppo%DLCO) estimation. The ppo values were compared using four different estimation methods between chronic obstructive pulmonary disease (COPD) and non-COPD patients and according to the resected lobe.

Methods

This prospective study included 59 eligible patients requiring single lobectomy and succeeded in performing pulmonary function tests at 3 and 12 months after lobectomy. The ppoFEV₁ and ppo%DLCO were compared with poFEV
