What is Esophagoscopy?
Esophagoscopy is a procedure in which your surgeon looks inside your food pipe. You may wonder about the purpose of esophagoscopy.
Why is an Esophagoscopy done?
When a foreign object like a coin, chicken bone, mutton bone, denture gets stuck in the throat, it’s serious. If it’s stuck anywhere in the food pipe, not going up or down then it has to be removed. Esophagoscopy is done to remove the foreign object.
Anything stuck in the food pipe will make eating and swallowing painful difficult and eventually can cause serious life-threatening infection. Esophagoscopy is done to remove the foreign object lodged in the esophagus or food pipe.
It is also done to take a biopsy or perform some procedure.
What is an Esophagoscope?
Esophagoscope is an endoscope.
There are two types of Flexible and rigid esophagoscope. The availability and ability for it in India depend on the tier of healthcare service.
A rigid esophagoscope is a tube-like structure which has a light attached to it and is introduced into the food pipe under general anesthesia. A flexible esophagoscope is, narrower and flexible and can be performed under local or General Anaesthesia.
Simple right?
Not really.
The procedures require a lot of skill and expertise of both the surgeon and anesthesia and has some serious contraindications and complications. The good news is if the patient presents early and has no serious medical condition and is an adult the course is easier. It gets complicated with toddlers, young children and elderly with multiple chronic lifestyle diseases.

Never delay checking with your doctor, if you suspect impaction of any foreign body in the throat or anything sticking in your throat for a long time than normal.
What are the conditions when an X-ray doesn’t show a foreign object and the patient has a complaint?
In case of a non-metallic foreign substance like plastic whistles etc, the Xray doesn’t pick up the object. Sometimes when people eat meat, post a heavy bout of drinking, the meat bolus may get stuck in the throat. This again will need a different set of investigation.
