A Study to Evaluate the Efficacy and Safety of Fenestrated Cup Forceps Versus Fenestrated Alligator Forceps for Performing Transbronchial Lung Biopsy in Patients With Sarcoidosis

Sarcoidosis is a systemic disease that results from granulomatous inflammation that involves multiple body organs. The diagnosis requires the presence of compatible clinicoradiological features along with histologic evidence that demonstrates non-caseating.1 Mediastinal lymph nodes and the lung parenchyma are the most commonly involved structures in sarcoidosis that can be sampled by, performing various bronchoscopic techniques. In a recent study the use of alligator forceps had a better yield in comparison to cup forceps. The investigators hypothesize that use of fenestrated alligator forceps in comparison to fenestrated cup forceps will yield larger samples, thereby improving the diagnostic yield and reducing the number of biopsy samples irrespective of the stage of sarcoidosis.
