From: Pneumoperitoneum caused by tracheal rupture due to tracheotomy: a case report
Tracheobronchoscopic view showing rupture of the tracheal membrane and granulation tissue proliferation. (A) The mucosa exhibited discontinuity, beginning approximately 3.5Â cm from the carina and extending to the membrane at the end of the intubation tube. (B) A false lumen was observed on the right wall during inhalation, with limited visibility of the distal end. (C) Increased presence of purulent slough covering the mucosal surface compared to previous observations
