His chest X-ray on admission suggested a large mass in his left lung field (Figure 1(a)) and his chest computed tomography revealed a tumor invading the left secondary carina (Figure 1(b)).
(a) Chest X-ray 3 days after admission revealed the progression of atelectasis in the left lung. (b) Chest X-ray on the day of intubation revealed complete atelectasis of the left lung. (c) Chest X-ray a day after the second electrocautery procedure showed marked improvement of the atelectasis of the left lung.

While waiting for the diagnostic bronchoscopy, he required tracheal intubation and mechanical ventilation due to atelectasis and obstructive pneumonia (Figures 2(a) and 2(b)). He was extubated following improvement of the atelectasis and obstructive pneumonia (Figure 2(c)).
(a) A polypoid tumor completely occluded the lumen of the left main bronchus. (b) After the first electrocautery procedure, the left inferior lobar bronchus could be partially visualized. (c) After the second electrocautery procedure performed 4 days after the first one, the left inferior lobar bronchus could be fully visualized.

Bronchoscopic examination showed that the left main bronchus was completely occluded by a polypoid tumor (Figure 3(a)). The first and second electrocautery required 153 and 108 minutes, respectively. The patency of the left inferior lobar bronchus was restored without complication after electrocautery (Figures 3(b) and 3(c)).
