Background Segmentectomy has been increasingly used for lung cancer treatment, however there are very limited data evaluating the postoperative pulmonary function of patients treated with complex segmentectomy. We evaluated the postoperative pulmonary function of patients who underwent complex segmentectomy compared with simple segmentectomy, wedge resection, and lobectomy. Methods We retrospectively analyzed data from 580 patients who underwent surgical resection. The patients were divided into four groups: complex segmentectomy (n = 135), simple segmentectomy (n = 83), wedge resection (n = 89), and lobectomy (n = 273). Functional testing included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and predicted diffusing capacity of the lung for carbon monoxide (%DLCO) measured preoperatively and at 12 months after surgery. Results During the postoperative course, the complex segmentectomy and simple segmentectomy groups showed a comparable course of pulmonary function. The complex segmentectomy group significantly preserved pulmonary function compared with the lobectomy group (FVC, p = 0.017; FEV1, p = 0.010; %DLCO, p = 0.0043). A similar trend was observed even when restricted to lung diseases in the right upper lobe. On the other hand, when comparing complex segmentectomy with wedge resection, complex segmentectomy showed a trend that was more disadvantageous than wedge resection, but this difference was not significant (FVC, p = 0.19; FEV1, p = 0.40; %DLCO, p = 0.96). Conclusions Complex segmentectomy showed comparable postoperative pulmonary functions as simple segmentectomy. Complex segmentectomy could preserve pulmonary function significantly compared with lobectomy and did not result in significant loss compared with wedge resection.
