Name of the Procedure:

Esophagoscopy, flexible, transoral; with biopsy, single or multiple

Summary

Esophagoscopy is a medical examination of the esophagus using a flexible tube with a camera (endoscope) inserted through the mouth. This procedure allows the doctor to view the esophagus and take tissue samples (biopsies) for further analysis.

Purpose

The procedure is used to diagnose and evaluate conditions affecting the esophagus, such as inflammation, tumors, infections, or other abnormalities. The goal is to identify the cause of symptoms like difficulty swallowing or persistent heartburn and to collect biopsy samples for laboratory testing.

Indications

• Persistent or unexplained heartburn (GERD)
• Difficulty swallowing (dysphagia)
• Unexplained weight loss
• Esophageal bleeding
• Suspected esophageal tumors or cancers
• Chronic cough or throat pain
• Abnormalities detected in imaging studies

Preparation

• Patients may be asked to fast for 6-8 hours before the procedure.
• Inform the doctor of any medications, especially blood thinners or anti-inflammatory drugs.
• Adjustments to medication may be required.
• Pre-procedure diagnostic tests like blood tests or imaging studies might be performed.

Procedure Description

1. Patient Preparation: The patient changes into a gown and lies on their side.
2. Sedation: Local anesthesia is sprayed into the throat, and sedatives are administered to help the patient relax.
3. Insertion: The flexible endoscope is gently inserted through the mouth and guided down the esophagus.
4. Examination: The doctor visually inspects the esophagus via the camera on the endoscope.
5. Biopsy: If abnormalities are detected, instruments are passed through the endoscope to take tissue samples.
6. Completion: The endoscope is carefully withdrawn.

Tools and Equipment:

• Flexible endoscope
• Biopsy forceps
• Sedatives and local anesthetic spray

Duration

The procedure typically takes 15-30 minutes.

Setting

Esophagoscopy is usually performed in a hospital, outpatient clinic, or an ambulatory surgical center.

Personnel

• Gastroenterologist or surgeon
• Nurses
• Anesthesiologist or anesthesia nurse

Risks and Complications

• Minor risks: Sore throat, mild bleeding at biopsy sites
• Less common risks: Perforation of the esophagus, infection, adverse reaction to sedation
• Rare complications: Significant bleeding or airway issues

Benefits

• Accurate diagnosis of esophageal conditions
• Direct visualization of the esophagus to identify abnormalities
• Early detection and treatment planning for esophageal diseases
• Biopsy samples for precise analysis

Recovery

• Observation for a short period post-procedure until sedation effects wear off.
• Mild throat soreness and bloating are common but temporary.
• Avoid eating or drinking until the gag reflex returns (usually a few hours).
• Follow-up appointment to discuss biopsy results and further treatment if needed.

Alternatives

• Barium swallow X-ray: Less invasive but not as detailed
• CT or MRI scans: Provide images of the esophagus but cannot take biopsies
• Capsule endoscopy: Swallowed camera pill, better for small intestine

Pros and Cons:

• Barium swallow: Less detailed, but no sedation required.
• CT/MRI: Detailed imaging, but cannot perform biopsies.
• Capsule endoscopy: Non-invasive, but limited to visualizing and cannot take tissue samples.

Patient Experience

• The patient might feel slight discomfort during the insertion of the endoscope.
• Sedation helps minimize discomfort and anxiety.
• Post-procedure, mild sore throat and a feeling of bloating are common but temporary.
• Pain management and comfort measures are provided throughout the recovery period.
