可彎曲胸腔鏡和硬質(zhì)胸腔鏡診斷不明原因胸腔積液的對比臨床研究
[Abstract]:Objective to compare the accuracy and safety of bendable thoracoscopy and rigid thoracoscopy in the diagnosis of unexplained pleural effusion. Methods prospective randomized controlled study was used to screen consecutive inpatients with unexplained pleural effusion aged 1875 years from March 2012 to March 2014 in Huaxi Hospital of Sichuan University. After informed consent, the patients were randomly assigned to the bendable or rigid thoracoscopic group. Results 49 patients in the flexible thoracoscopy group and 48 patients in the rigid thoracoscopy group. A total of 44 patients in both groups were diagnosed as malignant diseases and 48 benign diseases by thoracoscopy. The overall accuracy of the two groups in the diagnosis of pleural effusion of unknown cause was 93.9% and 95.8.The sensitivity of the flexible thoracoscopic group was 96.0 and that of the rigid thoracoscopic group was 95.2%. The specificity of diagnosis of tumor in the two groups was 100.0 and there was no significant difference between the two groups. Most of the complications of the two thoracoscopic techniques were mild and the patients were well tolerated. Conclusion for unexplained pleural effusion, the diagnostic accuracy of bendable thoracoscopy is equivalent to that of rigid thoracoscopy. Although the bendable thoracoscopic tissue is small, the tissue samples obtained by multiple points and multiple times can meet the needs of pathologists for the diagnosis of diseases, including immunohistochemical detection.
