In addition to stent insertion, a multitude of endobronchial endoscopy-assisted procedures can be carried out. In the case of complete bronchial occlusion, stent insertion immediately opens the postobstructed broncho-alveolar system. Often, postobstructive pneumonia, abscess formation or mucus retention can be treated with suction and lavage after stent insertion. In the case of mucosal tumors causing obstruction, endobronchial therapeutic measures such as laser ablation can be carried out to remove tumor burden prior to stent placement. 

TABLE 147.3 Objective Tumor Response of PDT versus Nd-YAG Laser for Obstructing Endobronchial Cancer (211 Patients)... 

George and colleagues (1992) treated nine patients with malignant central airway obstruction due to tracheal (n=3) or main bronchial ( =6) stenosis with Gianturco stents. All patients suffered from severe dyspnea or asphyxia (four were emergency treatments). All patients had dramatic and rapid reUef of their symptoms after stent insertion. Two patients with intraluminal tumor growth required additional endobronchial measures to control local tumor progression. Patients survived between 3 weeks and 8 months after the intervention. Causes of death were cachexia or pneumonia.
