Using electrocautery connected to the forceps (hot biopsy) is a way for controlling bleeding during sampling. But the main concern is if the sample tissue is sufficient for diagnosis, histological and pathologically or not. The aim of this study is to compare the diagnostic value of these two methods and also study their bleeding as a side effect.Materials and methods: In this study 36 patients with endobronchial lesions underwent flexible bronchoscopy. First, three samples were taken without coagulation (Cold) and then three more were taken with coagulation (hot) at voltages 10,20 and 40. The samples were blindly studied by pathologist. The severity of bleeding was determined by a non bronchoscopist.Results: There was a meaningful difference between the amount of bleeding in hot and cold methods (p<0/05), but not between different voltages (p>0/05). There was no difference in the rate of tissue damage in voltages 20 and 40, but a meaningful difference was observed between the two voltage sets of 10 and 40 (p=0/048), and in 10 and 20 (p=0/047).Conclusion: Using hot biopsy method in diagnosing endobronchial tumoral lesions reduced the amount of severe bleeding and the rate of tissue damage was not affecting the histological and pathological studying.
