Differences in postoperative changes in pulmonary functions following segmentectomy compared with lobectomy

Abstract OBJECTIVES To clarify differences in postoperative changes in systemic and regional pulmonary functions between segmentectomy and lobectomy in patients with lung cancer, we compared the 2 procedures using lung perfusion scintigraphy with a fusion image of single-photon emission computed tom...

Description
Summary:Abstract OBJECTIVES To clarify differences in postoperative changes in systemic and regional pulmonary functions between segmentectomy and lobectomy in patients with lung cancer, we compared the 2 procedures using lung perfusion scintigraphy with a fusion image of single-photon emission computed tomography and computed tomography. METHODS This study is a retrospective matched cohort study of consecutively acquired data. Pulmonary function tests and perfusion single-photon emission computed tomography/computed tomography were conducted before surgery and 6 months after surgery to measure changes in forced expiratory volume in 1 s of a whole lung, contralateral lung and a lobe. After exactly matching the site of the resected lobe between the 2 procedures, propensity scores for age, sex, smoking status and pulmonary function were used to match them. RESULTS Of the 184 patients treated with segmentectomy and the 208 patients treated with lobectomy between 2013 and 2016, 103 patients were selected from each group after the matching. Whole lung function was significantly more preserved after segmentectomy than after lobectomy (P
