Changes in pulmonary function in lung cancer patients after segmentectomy or lobectomy: a retrospective, non-intervention, observation study

Overall loss of pulmonary function was much greater after LE than after both SSE and MSE. MSE was associated with higher postoperative pulmonary function decline compared to SSE but was still beneficial over LE. Both LE and SE groups had similar PFT loss per segment (P > 0.05).
