“…6 Jabbardarjani et al 13 found no difference in the rate of tissue damage at voltages 20 and 40. When Rault et al 14 evaluated the impact of hot biopsy on endobronchial tissue samples, soft coagulation at power settings of 20, 25, and 30 W, did not affect the quality of specimens. Their findings are in agreement with our study.…”

Background: Flexible bronchoscopy-guided endobronchial biopsy (EBB) is routinely performed as an outpatient daycare procedure. Bleeding after EBB is a common complication, that at times disrupts the procedure and can rarely lead to a catastrophe. We aimed to compare the efficacy of prebiopsy prophylactic bronchoscopic electrocautery with adrenaline and cold saline instillation in achieving hemostasis in patients with endobronchial lesions with a higher risk of bleeding during EBB. Methods: In this open-label, randomized controlled trial, 60 patients with endobronchial lesions were randomized to either the prophylactic electrocautery arm or the adrenaline and cold saline arm. Postbiopsy endobronchial bleed was quantified in millimeters using the Visual Analog Scale (VAS) and graded as per the British Thoracic Society grading system. Electrocautery-induced tissue damage was graded by the pathologist as “no damage,” “mild,” “moderate,” and “severe.” Results: The median VAS score of bleeding was 6.14 mm (interquartile range: 8 mm) in the electrocautery arm and 10.17 mm (interquartile range: 7 mm) in the adrenaline and cold saline arm. Though the difference in the VAS score of bleeding between the two groups was statistically significant, there was no significant difference in the proportion of grade 2 or higher bleeding. Conclusion: No difference in postbiopsy bleed was observed between the application of electrocautery or instillation of cold saline plus adrenaline before biopsy of those endobronchial lesions which were likely to bleed more after biopsy. Although controlled prophylactic electrocautery using 15 watts did not impair the quality of EBB specimens, a higher wattage may change this observation, as well as the bleeding quantity.
