High resolution computed tomography HRCT has been used for the preoperative detection of ELCs. However the traditional HRCT method uses only the axial view which is perpendicular to the distribution of ELCs. This is not an ideal diagnostic method for the evaluation of ELCs. Methods Forty-eight patients with pneumothorax had multi-detector computed tomography MDCT reconstruction using the coronal view. ELCs were evaluated in the axial and coronal view by a radiologist. A surgeon performed intra-operative examinations of the ELCs. The sensitivity of the different views was compared. Results The detection sensitivity was 70 94 for the axial view and 86 94 for the axial-coronal combined view. The intra-operative detection rate was 90 94 . The preoperative detection of ELCs on the axial-coronal combined view was significantly higher than on the conventional axial view alone p . Conclusions Evaluation of ELCs on the axial and coronal combined HRCT improved the sensitivity of preoperative detection of ELCs compared to the conventional single axial HRCT. This increased sensitivity will help decrease the recurrence with VATS. Background The recurrence of a pneumothorax after video assisted thoracic surgery VATS after the treatment of primary spontaneous pneumothorax is higher than after thoracotomy procedures 1-8 . Although it is difficult to prove the cause of higher recurrence rates it has been suggested that videoscopic inspection is less accurate than direct inspection this
