Diagnostic Value And Morphological Features For Unexplained And Malignant Pleural Effusion Under Medical Thoracoscopy Examiantion

Objective To investigate the clinical diagnostic value and the morphological features of malignant pleural effusion under medical thoracoscopy examination.Methods The results of pathological biopsy,the morphological features of malignant pleural effusion under medical thoracoscopy,the perioperative complications,CEA and ADA of 98 patients,who accepted the examination of medical thoracoscopy in our department because of unknown pleural effusion from January 2015 to January 2018 were analyzed retrospectively.Results There were 89 cases were definitely diagnosed(90.82%)including 36 malignant pleural effusion(94.74%)among 98 patients.The morphological features of malignant pleural effusion under medical thoracoscopy showed mainly 1 normal pleura,2 lesions of ulcerative erosion,1 single nodule,2 miliary nodules,27 multiple nodules and 3 multiple nodules to extensive leukoplakia like lesions.Complications of the patients underwent medical thoracosopy were mainly chest pain,subcutaneous emphysema and fever.Conclusions Medical thoracoscopy examination is a minimally invasive,safe and effective technology for diagnosis of unexplained pleural effusion with high exact diagnosis rate.It has a significant value in diagnosing unknown pleural effusion.Malignant pleural effusions take on with unique morphological features under medical thoracoscopy examination.The exact awareness of morphological features of malignant pleural effusions under medical thoracoscopy is of significance for guiding precise multipoint biopsy and early diagnosis.
