Esophagoscopy is a medical procedure that involves the use of a flexible endoscope to visualize the esophagus, which is the tube that connects the throat to the stomach. This procedure is specifically performed to control bleeding within the esophagus, utilizing various methods such as injection, cautery, laser, heater probe, stapler, plasma coagulator, or other techniques. The flexible endoscope is introduced through the mouth and carefully advanced into the esophagus, allowing for a thorough examination of the velopharyngeal closure, the base of the tongue, and the hypopharynx. During the procedure, the motion of the vocal cords is observed, and the musculature of the pharynx is evaluated to ensure proper function. As the endoscope reaches the cricopharyngeus, the patient may be instructed to burp or swallow, which aids in the smooth passage of the scope through the esophagus to the gastroesophageal junction. Any abnormalities encountered during this process are meticulously noted. Once the scope is withdrawn, a comprehensive examination of the entire circumference of the esophagus is conducted to identify the specific site of bleeding. The control of bleeding is typically achieved through the application of heat via contact thermal modalities, such as bipolar or unipolar cautery or a heater probe, which are applied directly to the bleeding point while pressure is maintained. Additionally, an injection of epinephrine may be utilized to act as a vasoconstrictor, helping to reduce or halt the bleeding. Noncontact devices, such as YAG (Yttrium-Aluminum Garnet) laser coagulation and the argon plasma coagulator, are also employed to effectively coagulate the bleeding site. In cases of tears or lacerations, staples or hemoclips may be used to approximate the margins, facilitating proper healing and control of the bleeding.
