What Is an Endoscopy?

An endoscopy is a medical procedure that uses a thin, flexible tube (endoscope) equipped with a camera and light to examine the inside of the digestive system. This allows for real-time visualization of the esophagus, stomach, small intestine, and colon. Endoscopy is commonly used to:

  • Diagnose digestive disorders such as acid reflux, ulcers, or celiac disease
  • Identify causes of symptoms like persistent nausea, bloating, or difficulty swallowing
  • Detect early signs of cancer in the gastrointestinal tract
  • Perform minor procedures, such as removing polyps or treating bleeding ulcers

Types of Endoscopy Procedures

Depending on the symptoms and area of concern, different types of endoscopy may be recommended:

  • Upper Endoscopy (EGD) – Examines the esophagus, stomach, and upper small intestine to detect acid reflux, ulcers, or swallowing disorders.
  • Colonoscopy – Evaluates the colon and rectum to identify polyps, inflammation, or early signs of colon cancer.
  • Flexible Sigmoidoscopy – Focuses on the lower portion of the colon, often used for diagnosing rectal bleeding or inflammatory conditions.
  • Endoscopic Ultrasound (EUS) – Combines ultrasound imaging with endoscopy to assess organs surrounding the digestive tract, such as the pancreas and liver.
  • Capsule Endoscopy – Uses a small, swallowable camera pill to capture images of the small intestine, particularly for conditions that may not be visible with standard endoscopy.

What to Expect Before an Endoscopy

Proper preparation ensures a successful and accurate procedure. Prior to your EGD in Chandler & Mesa at AZ Gastro Care, you will receive specific instructions based on the type of procedure you are undergoing. For upper endoscopy, patients are typically required to fast for several hours before the procedure.

For colonoscopy or sigmoidoscopy, a bowel preparation regimen (liquid diet and laxatives) may be needed to clear the digestive tract. Arrange for transportation, as sedation is commonly used to ensure comfort during the procedure.

What Happens During an Endoscopy?

Endoscopies are generally quick, minimally invasive, and well-tolerated procedures.

  • Sedation is administered to ensure relaxation and comfort.
  • For an upper endoscopy, the endoscope is gently inserted through the throat to examine the esophagus, stomach, and small intestine.
  • For a colonoscopy or sigmoidoscopy, the endoscope is inserted through the rectum to examine the lower digestive tract.
  • The procedure typically takes 15 to 60 minutes, depending on the findings and whether any additional treatments, such as polyp removal or biopsy, are needed.

What Happens After the Procedure?

Following the procedure, patients recover in a monitored setting until the effects of sedation wear off. Mild side effects such as bloating, gas, or a sore throat may occur but usually resolve quickly. For colonoscopies, a small amount of blood in the first bowel movement may be normal, especially if polyps were removed. Results will be reviewed, and any additional follow-up testing or treatments will be discussed as needed.
