Gastroscope-assisted oral cavity and nasopharynx examination.

ABSTRACT:

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 anatom
