Bleeding
None	19 (38%)
Mild	19 (38%)
Moderate	12 (24%)
Severe	0
Pneumothorax
Mild	5 (10%)
Severe	0

Bleeding severity scale: no bleeding, mild bleeding (requiring suction to clear but no other endoscopic procedures), moderate bleeding (requiring instillation of ice-cold saline and/or adrenaline and/or bronchial blocker re-inflation), and severe bleeding (causing hemodynamic or respiratory instability, requiring tamponade, transfusions or admission to the intensive care unit). Pneumothorax severity scale: mild (small pneumothorax >2 cm rim present between the lung edge and chest wall, requiring only high flow oxygen supplementation), severe (large pneumothorax <2 cm rim present between the lung edge and chest wall, requiring active intervention (requiring chest drain insertion).
