Pulmonary Function After Lobectomy: Video-Assisted Thoracoscopic Surgery Versus Muscle-Sparing Mini-thoracotomy.

Although pulmonary function was better after video-assisted thoracoscopic surgery (VATS) lobectomy than after open thoracotomy lobectomy, it is unclear whether postoperative pulmonary function after VATS lobectomy is better than that after mini-thoracotomy lobectomy. The aim of this study is to determine whether the former is better than the latter. VATS lobectomies were performed using endoscopic techniques through a 3-4-cm skin incision spread by a silicon rubber retractor and two or three trocars.

Recurrence and metastasis of lung cancer demonstrate decreased diffusion on diffusion-weighted magnetic resonance imaging.

Background: Diffusion-weighted magnetic resonance imaging (DWI) is reported to be useful for detecting malignant lesions. The purpose of this study is to clarify characteristics of imaging, detection rate and sensitivity of DWI for recurrence or metastasis of lung cancer.

Methods: A total of 36 lung cancer patients with recurrence or metastasis were enrolled in this study.
