Introduction to Esophagoscopy: Types, Contraindications, Procedure, and Hazards

Esophagoscopy is the term used to describe the examination of the oesophagus using an Esophagoscope. An esophagoscope is an instrument used to observe the oesophagus. It is made of a narrow tube with a light and lens connected to it. It has several uses as a trustworthy diagnostic and therapeutic tool.

What Is an Esophageal Scan?

Esophagoscopy is the term for the endoscopic examination of the oesophagus. An esophagoscope is an instrument used to observe the oesophagus. It is made of a narrow tube with a light and lens connected to it. Long and muscular, the oesophagus assists in moving food and drink from the mouth cavity to the stomach. Moreover, it has a tool for slicing up the oesophagus so that tissue may be removed for biopsy or other testing.

Are Endoscopy and Esophagoscopy the Same Thing?

The process used to observe inside organs and cavities is called an endoscopy. The endoscope and other necessary instruments for the treatment may need to be inserted via an incision.

While an esophagoscopy is likewise a sort of endoscopy, it varies from an endoscopy in that it does not involve making incisions. An endoscope is instead placed via the mouth into the food pipe (oesophagus) during an esophagoscopy to observe the upper digestive system. Both a physical examination and ultrasound imaging may be used in the treatment.

What Kinds of Esophagoscopies Are There?

The many esophagoscopy procedures include:

Rigid Esophagoscopy: During this technique, a hard, stiff tube is inserted via the mouth into the oesophagus. The upper GI tract’s interior features, including the oesophagus, may be seen using the tube’s eyepiece, lenses, and illumination. This kind is often used for diagnostic reasons and in small procedures.

Flexible esophagoscopy: In this kind, the oesophagus is examined via the mouth using a thin, flexible tube. In the tube are little electrical lines that provide light to observe the construction. To see the photos that were collected, these connections are connected to the display.

The least invasive method, transnasal esophagoscopy is performed without the need of anaesthetic. The endoscope, which is mostly used for diagnostic reasons, is put into the nose, through the nasal cavity, down the back, and into the oesophagus.

The Purpose of an Endoscopy

If the patient complains of laryngopharyngeal reflux (stomach acid moving through the oesophagus into the throat), persistent heartburn despite medication and lifestyle changes, difficulty swallowing, feeling a lump in the throat while swallowing, etc., an esophagoscope may be used as part of the physical examination. It makes diagnosis for disorders of the oesophagus, stomach, and intestine. Esophagoscopy is often only performed in conjunction with a more thorough endoscopy to see the oesophagus, stomach, and upper portions of the intestine. It is used to

  • Look into the reasons behind any unusual intestinal, stomach, or throat problems.
  • To identify diseases like a cancerous tumour or others like dysphagia or GERD, do a biopsy (Gastroesophageal reflux disease).
  • Eliminate any foreign material or huge bolus of food from the oesophagus.
  • Imagine the digestive system under anaesthesia.
  • Barrett’s oesophagus is a disorder where intestinal tissue takes the place of the normal esophageal tissue.
  • Veins in the oesophagus are enlarged.
  • A neoplastic tissue growth.

When Should an Endoscopy Not Be Performed?

With a complication risk of 1 in 1000 operations, esophagoscopy is a rather safe treatment. In the following circumstances, it is categorically contraindicated:

An inadequate blood supply to the organs may result from hemodynamic instability, a condition in which there is an unnatural instability in blood pressure.

  • Not getting permission for the surgery.
  • High likelihood of perforation

The following relative contraindications:

  • Anticoagulation given the right circumstances (like esophageal dilation).
  • Neck and head surgery.
  • The lower portion of the neck joins the higher portion of the oesophagus to produce the pharyngeal diverticulum, also known as Zenker’s diverticulum.
  • Patients who have previously had procedural intolerance.

The Process of an Endoscopy

Depending on the treatment, it might take anywhere from 30 minutes to 3 hours. The surgery is often performed as an outpatient, allowing the patient to leave the hospital the same day. The steps consist of:

  • In order to make the surgery more comfortable, anaesthesia is administered. A topical anaesthetic or an IV might be used, depending on the surgery.
  • The endoscope is slowly and delicately pushed into the throat via the mouth or nose.
  • Via the eyepiece or the monitor showing the recorded pictures, the doctor observes. A little quantity of air may sometimes be pumped into the oesophagus to help with visualisation.
  • In order to remove the aberrant tissues or bulk or to suction out any obstructions in the oesophagus, instruments like forceps or a hollow suction tube are utilised.
  • Carries out any operations required to address esophageal problems.
  • The endoscope is gently withdrawn after the surgery. The patient is given time to recover from the anaesthetic while being watched for any issues after the treatment.

What Consequences Come With an Esophagoscopy?

An esophagoscopy is thought to have very minor hazards. The majority of recorded problems are transient and resolve promptly. Potential dangers include:

  • Discomfort, agony, or soreness in the throat.
  • Voice that is hoarse.
  • A brief period of mild swallowing difficulties.
  • Esophageal tissue irritation, damage, and perforation (tearing).
  • Air embalmed under the skin (subcutaneous surgical emphysema).
  • Hemorrhage or bleeding internally.
  • Infection.
  • Fever.
  • Responses due to allergies to the anaesthetic administered.
  • Negative effects of medicine.
  • Aspiration.
  • Oversedation.
  • Airway blockage.

How Has the Post-Procedure Recovering Been?

  • After the surgery, the patient would likely feel exhausted, particularly if anaesthetic was used. Yet, the anesthesia’s effects would wear off after a day. After a few hours of monitoring after the surgery, the patient would be released. The patient should go home with a bystander since they may be too weak to drive alone. The procedure’s pain will eventually subside. See a doctor if any of the following occur:
  • With time, discomfort and pain become worse.
  • Vomit or stools contain blood.
  • Trouble breathing
  • Chest pain
  • Fever.


Esophagogastric endoscopy is a versatile diagnostic and therapeutic technique using a Esophagoscope. It is one of the most reliable and efficient diagnostic methods for diseases of the upper GI tract.
