Can a gastroscope detect throat lesions?

Generally speaking, the throat refers to the pharynx. Whether an endoscope can detect pharyngeal lesions depends on the specific circumstances. If there are obvious lesions in the pharyngeal area, they can usually be observed; however, if the pharyngeal lesions are minor, they may not be visible. Detailed explanation is as follows:

The primary purpose of an endoscope is to examine the interior of the esophagus, stomach, and duodenum. However, while passing through the throat to reach the esophagus, doctors can simultaneously observe certain structures of the pharynx, such as the epiglottis, arytenoid cartilage, and pyriform sinus. If there are obvious abnormalities in these areas, such as large masses, ulcers, or severe inflammation, they may be detected by endoscopy. As the endoscope passes through the throat, its tube glides over these areas, giving the physician an opportunity to observe their appearance. Therefore, to some extent, abnormalities in the pharyngeal region can be detected via endoscopy.

However, if the pharyngeal lesions are minor, they may be difficult to detect. This is because the throat is not the main focus of endoscopic observation, and the complex structure and relatively narrow space of the pharynx pose certain challenges for visualization. Consequently, subtle lesions or abnormalities deeply embedded within the tissue may not be accurately identified by endoscopy.

If there is suspicion of pharyngeal discomfort or lesions, it is recommended to undergo laryngoscopy under the guidance of a physician.
