Sarcoidosis involves the respiratory system in \\> 90% of cases, usually the hilar and mediastinal nodes, and, less frequently, the lung tissue. Airway involvement, as judged by clinical features, physiologic testing, imaging techniques, bronchoscopy, and airway mucosal biopsy, has been observed in nearly two-thirds of patients with sarcoidosis. Although sarcoidosis involving thoracic lymph nodes and pulmonary parenchyma is familiar to most clinicians, airway involvement is often overlooked. The frequency of airway involvement increases as the parenchymal disease progresses, and\\\\airway involvement is associated with increased morbidity, respiratory symptoms, and mortality. The initial airway abnormality is the inflammation manifested by mucosal edema, erythema, and the formation of granulomas. As the airway disease progresses, the mucosa may demonstrate granularity, nodularity, cobble stoning, and friability. Sarcoid granulomas tend to develop along the bronchovascular bundle or in the vicinity of the airways. Overall quality of the endobronchial biopsy (EBB) will depend on the method by which it is obtained and cryo-EBB will most likely to provide better tissue for the diagnosis in comparison to forceps biopsy which has smaller sample as well as crush artifacts. Therefore, it is hypothesized that cryo-EBB will be better than forceps EBB and combined together it will increase the overall diagnostic yield of the sarcoidosis when combined with lymph node sampling by endobronchial ultrasound guided trans-bronchial needle aspiration (EBUS-TBNA).\n\n1. Primary objective: To compare the diagnostic yield of cryo-EBB with forceps biopsy in patients undergoing routine EBUS-TBNA for suspected sarcoidosis.\n2. Secondary Objective: To evaluate the overall diagnostic yield of combined endobronchial biopsy and EBUS-TBNA in patients undergoing routine EBUS-TBNA for suspected sarcoidosis.\n\nThe relevance and the expected outcome of the proposed study\n\n1. The study will provide insight to obtain an endobronchial biopsy either with cryo probe or forceps\n2. The study will also provide information regarding overall increase in diagnostic yield if any when the endobronchial biopsies are combined with EBUS-TBNA.', 'detailedDescription': 'The study will consist of consecutive patients undergoing routine EBUS-TBNA for suspected sarcoidosis AND subsequently confirmed on clinical, radiology and non-caseating granuloma on histopathology. .\n\n150 patients will be randomized into either cryo-EBB or forceps biopsy from a computer-generated randomized table. 75 patients will be included in each arm.\n\nDetermination of the sample size was based on the primary outcome of the proportion of diagnostic yield between two independent groups. Using the z test of proportion for two independent samples to detect a one-sided target difference between the groups of 15% with 85% power and a level of significance of 5%, each group required 69 participants. With an expected attrition rate of 8-10%, we capped the total number of participants in each arm of the study at 75.\n\nSubsequent to EBUS-TBNA, video bronchoscopy will be performed to obtain the endobronchial biopsy by using either forceps or cryo-proble. Three endobronchial biopsies from primary carina and both left and right secondary carina will be taken in each patients irrespective of the endobronchial abnormality. Additional biopsies will be taken from any endobronchial abnormality detected during the examination.\n\nThe biopsy samples will be fixed in neutral 10% buffered formalin. In the pathology laboratory the sample will be embedded in paraffin followed by staining with hematoxylin and eosin or special stain according to the requirement to allow an exact classification. The samples will be analyzed and assessed by one pathologist according to common standards describing adequacy of the sample, crush artifacts, specific diagnosis. The pathologist will be blinded from the biopsy technique that has been used.\n\nDiagnostic yield will be defined by the ability to make an adequate diagnosis on histopathological examination of the sampled tissue. Diagnostic yield will be calculated for each biopsy technique as the number of diagnostic procedures divided by number of non-diagnostic procedures plus the number of diagnostic procedures.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nAll patients of suspected pulmonary sarcoidosis scheduled for routine EBUS-TBNA\n\nExclusion Criteria:\n\n1.
