Esophagoscopy, flexible, transoral, with endoscopic mucosal resection, is a specialized medical procedure that involves the use of a flexible endoscope to visualize and treat lesions within the esophagus. This procedure is particularly significant for addressing dysplastic or precancerous lesions, as well as small, early-stage cancerous lesions that are confined to the mucosal layer of the esophagus. The flexible endoscope is introduced through the mouth and carefully advanced into the esophagus, allowing the physician to reach the specific area where the lesion is located. During the procedure, the borders of the lesion are marked using electrocautery, which helps delineate the area for removal. To facilitate the excision, diluted adrenaline is injected into the submucosal layer surrounding the lesion, effectively lifting the mucosal layer and creating a separation from the underlying muscle tissue. This technique enhances the visibility and accessibility of the lesion. A snare equipped with a suction cup is then employed to grasp and excise the lesion, which is subsequently captured for analysis. After the lesion is removed, the endoscope is withdrawn, and a thorough examination of the entire esophagus is conducted to ensure no additional lesions are present. The excised tissue is sent for pathological examination, which is reported separately, providing critical information for further management and treatment decisions.
