Chest computed tomography is commonly used in patients with primary spontaneous pneumothorax to detect the presence of pulmonary blebs or bullae. The aim of this study is to calculate the accuracy of chest computed tomography to detect surgically resectable blebs or bullae in patients with primary spontaneous pneumothorax.
This is a retrospective study includes all patients with primary spontaneous pneumothorax who underwent chest computed tomography evaluation for their disease over the period from January 2005 to December 2015. Patients who underwent surgical exploration were sub-grouped to calculate the sensitivity and the specificity of the chest computed tomography to detect surgically resectable pulmonary blebs or bullae.
A total of 143 patients were included in the study. Among them, 120 patients underwent surgical exploration with the finding of 95.7% sensitivity and 42.3% specificity for the chest computed tomography in detection of surgically resectable pulmonary blebs or bullae.
The sensitivity of the chest computed tomography scan is high in detecting surgically resectable pulmonary blebs or bullae. However, the specificity is low. This may lead to overdiagnosis of the patients to have pulmonary blebs and bullae. Therefore, the routine use of chest computed tomography scan before the surgical exploration in patients with primary spontaneous pneumothorax should depend on the clinical judgment.
胸部计算机断层扫描常用于原发性自发性气胸患者，以检测肺疱或大疱的存在。本研究旨在计算胸部计算机断层扫描检测原发性自发性气胸患者可手术切除疱或大疱的准确性。
这是一项回顾性研究，包括 2005 年 1 月至 2015 年 12 月期间因疾病接受胸部计算机断层扫描评估的所有原发性自发性气胸患者。对接受手术探查的患者进行亚组分析，以计算胸部计算机断层扫描检测可手术切除的肺疱或大疱的敏感性和特异性。
共有 143 例患者纳入研究。其中，120 例患者接受了手术探查，胸部计算机断层扫描对可手术切除的肺疱或大疱的检测敏感性为 95.7%，特异性为 42.3%。
胸部计算机断层扫描在检测可手术切除的肺疱或大疱方面具有较高的敏感性。然而，特异性较低。这可能导致对患者存在肺疱和大疱的过度诊断。因此，在原发性自发性气胸患者进行手术探查前，常规使用胸部计算机断层扫描应取决于临床判断。
