Upper Endoscopy: What is it, Who needs it, What it involves, Risks and Benefits

In the realm of gastroenterology, upper endoscopy is a vital diagnostic and treatment procedure. During an upper endoscopy, a gastroenterologist employs a specialized tool known as an endoscope to examine the inner workings of the esophagus, stomach, and duodenum, which is the initial segment of the small intestine. This versatile technique is employed to identify and address a spectrum of gastrointestinal issues, encompassing acid reflux, stomach ulcers, celiac disease, gastrointestinal disorders, and a multitude of other digestive system complications.

Upper Endoscopy Overview

Understanding the Basics of Upper Endoscopy

Also referred to as esophagogastroduodenoscopy, or simply EGD, upper endoscopy is a procedure designed to investigate the upper part of the digestive tract. A gastroenterologist wields an endoscope—a slender, flexible tube equipped with a light and a tiny video camera—to explore the inner lining of the following organs:

  1. Esophagus: This conduit transports food from the mouth to the stomach.
  2. Stomach: The hub for food storage and the commencement of the digestion process.
  3. Duodenum: The upper portion of the small intestine.

Indications for an Upper Endoscopy

Individuals may necessitate an upper endoscopy if they experience unexplained symptoms such as:

  • Abdominal pain
  • Bleeding in the upper digestive tract
  • Nausea and vomiting
  • Swallowing difficulties
  • Unexplained weight loss

The Role of Upper Endoscopy in Healthcare

Upper endoscopy offers the advantage of direct visualization and the collection of biopsies, rendering it more precise than X-rays in diagnosing upper digestive system ailments. These include:

  • Acid reflux (gastroesophageal reflux disease or GERD) and heartburn
  • Both cancerous and noncancerous tumors
  • Inflammatory conditions like esophagitis, gastritis, and duodenitis
  • Gastrointestinal disorders, including celiac disease and Crohn’s disease
  • Peptic ulcers in the stomach
  • Swallowing disorders

Diverse Applications of Upper Endoscopy

In addition to diagnostics, healthcare providers can also perform therapeutic interventions with an endoscope. In certain cases, your doctor might use upper endoscopy to:

  • Manage upper digestive tract bleeding
  • Dilate narrowed digestive passages
  • Extract polyps, tumors, or ingested objects

Integration with Other Procedures

Upper endoscopy is sometimes paired with other medical techniques, such as:

  • X-rays: This combination, known as endoscopic retrograde cholangiopancreatography (ERCP), is employed to diagnose and treat issues impacting the liver, pancreas, gallbladder, and bile ducts by utilizing injected dye.
  • Ultrasound: Endoscopic ultrasound (EUS) is utilized to create imagery of the digestive tract and its neighboring structures, encompassing organs, lymph nodes, and tissues.

Procedure Details

Preparation for Upper Endoscopy

To ensure a clear view of the digestive tract, it’s essential to undergo the procedure on an empty stomach. Your doctor will guide you through the preparation process, which may include:

  • Dietary restrictions: You’ll typically be limited to clear liquids (like broth, gelatin, popsicles, water, black coffee, or tea) for six to eight hours prior to the procedure.
  • Medication adjustments: Certain medications, especially blood thinners like aspirin, might need to be temporarily discontinued. In some instances, modifications to diabetes or high blood pressure medications may be necessary.

The Upper Endoscopy Process

An upper endoscopy is generally conducted as an outpatient procedure, meaning you can return home on the same day. While the procedure might be slightly uncomfortable, it should not be painful. You’ll receive an intravenous sedative or another form of anesthesia. For safety reasons, arrange for someone to drive you home after the procedure.

During the procedure, you’ll lie on your left side, which typically takes around 30 minutes. Your doctor follows this sequence:

  • Administers a numbing spray to your throat and places a mouthguard to protect your teeth.
  • Guides the endoscope through your mouth and into the esophagus, stomach, and duodenum.
  • Introduces air through the endoscope to facilitate organ visibility.
  • Monitors images from the endoscope on a video screen while assessing problems or administering treatments.
  • Collects small tissue samples for biopsy, if required.
  • Performs treatments if deemed necessary.

Recovery Following Upper Endoscopy

After the procedure, you’ll spend a brief recovery period as the sedative gradually wears off. Upper endoscopy may cause throat irritation, resulting in temporary hoarseness or a cough that lasts a few days. You can ease any discomfort by consuming soft foods, drinking ice water, and utilizing throat lozenges.

Some patients might encounter bloating (a consequence of the introduced air) and experience mild nausea due to the anesthesia. Typically, you can resume your regular activities, including work and driving, with your doctor’s consent the following day.

Risks and Benefits of Upper Endoscopy

Potential Complications of Upper Endoscopy

Upper endoscopy is considered a low-risk procedure. Potential complications may encompass:

  • Allergic reactions to the sedative
  • Bleeding or infection within the digestive tract
  • Perforations in the digestive tract lining

Recovery and Outlook

Receiving Test Results

Your doctor may provide immediate diagnostic findings. However, if biopsies are conducted, it might take up to two weeks to receive the results.

When to Contact Your Doctor

Don’t hesitate to contact your healthcare provider if you encounter any of the following symptoms:

  • Chronic cough or coughing up blood or vomit containing blood
  • Difficulty swallowing
  • Fever and chills
  • Rectal bleeding, characterized by black, tarry stool
  • Severe throat pain, chest pain, or abdominal pain

In Conclusion

Upper endoscopy is a remarkably safe procedure that assists in diagnosing the underlying causes of specific digestive tract issues. It also serves as a valuable tool for treatment. While some post-procedural discomfort may be experienced, it’s a minor inconvenience considering the wealth of information it provides for medical practitioners and their patients.
