BACKGROUND AND AIMS: The oral cavity and nasopharynx are often overlooked during EGD, despite their relevance in early detection of upper aerodigestive pathologies. This video introduces a standardized, cap-assisted gastroscope technique to assess these areas during routine EGD that aims to improve anatomical recognition and opportunistic screening.
METHODS: We demonstrate a cap-assisted technique using a standard gastroscope with a distal attachment to evaluate the oral cavity presedation via 4 standardized positions (tongue down, right, left, up), and the nasopharynx via retroflexion in sedated patients. Both assessments are completed within 20 seconds and recorded for educational and diagnostic value.
RESULTS: Oral cavity assessment enables visualization of key anatomical landmarks and allows identification of mucosal abnormalities. Nasopharyngeal visualization is successful in more than 90% of cases, with clear views of structures such as the Eustachian tubes and posterior pharyngeal wall. Both techniques are safe, efficient, and reproducible, enhancing procedural scope and trainee education.
CONCLUSIONS: Cap-assisted oral cavity and nasopharynx examinations can be safely integrated into routine EGD, expanding its diagnostic reach. These standardized techniques offer educational value and potential for early lesion detection, justifying further prospective validation in high-risk populations.
