panendoscopy
Comprehensive endoscopic examination of the upper aerodigestive tract including nasal cavity, oral cavity, pharynx, and larynx. Standard staging procedure in head and neck cancer.
Full Definition
Panendoscopy is a systematic endoscopic evaluation of the entire upper aerodigestive tract performed under general anesthesia to assess the extent of disease and identify synchronous primary tumors. The procedure includes direct laryngoscopy, esophagoscopy, and bronchoscopy, allowing visualization of areas from the nasal cavity to the upper esophagus and tracheobronchial tree. In head and neck oncology, panendoscopy is essential for accurate staging, biopsy of suspicious areas, and detection of second primary malignancies, which occur in 10-15% of patients with squamous cell carcinomas of the head and neck.
Usage
Usage note: Distinguish from individual endoscopic procedures; implies comprehensive multi-site examination.
