Chest X-ray showed a reticular shadow in the left lung hilum (Fig. 1A). Chest CT imaging showed segmental atelectasis of the left lower lobe and a round tumor shadow at the orifice of the left lower bronchus that protruded into the left main bronchus (Fig. 1B).
(A) Chest X-ray at 1 month after patient's first visit to our hospital, showing total atelectasis of the left lung field. (B) Chest CT scan showing total atelectasis of the left lung due to obstruction of left main bronchus by endobronchial tumor in the left main bronchus.

Chest X-ray showed total atelectasis of the left lung field (Fig. 2A). Chest CT scan showed total atelectasis of the left lung due to obstruction of left main bronchus by the endobronchial tumor in the left main bronchus (Fig. 2B).

The chest X-rays showed re-expansion of the left upper lobe (Fig. 4).
(A) Bronchoscopy performed at 2 weeks after surgery showed bronchial kinking, and the formation of an ulcer at the opposite site of the anastomosis line, (B) which spontaneously healed after 1 month. (C) Chest X-ray at 2 year after surgery.

Although the patient's postoperative condition was uneventful, bronchoscopy performed at 2 weeks after surgery showed bronchial kinking and small ulcer formation at the opposite site of the anastomosis line (Fig. 5A). However, this ulcer spontaneously healed 1 month later (Fig. 5B). The patient has been carefully followed at our outpatient clinic using CT imaging and bronchofiberscopy, and left bronchial luminal patency was good without recurrence or stenosis 2 years after surgery (Fig. 5C).
