Gastroscopy

Gastroscopy, also known as upper endoscopy, is a medical procedure that allows a doctor to visually examine the upper digestive system, including the esophagus, stomach, and duodenum (the first part of the small intestine).

What is Gastroscopy Used For?

Gastroscopy is used to diagnose and treat various conditions affecting the upper digestive system, such as:

• Gastroesophageal reflux disease (GERD)
• Peptic ulcers
• Gastritis
• Cancer of the esophagus, stomach, or duodenum
• Inflammatory bowel disease (IBD)
• Bleeding in the upper digestive system
• Difficulty swallowing (dysphagia)
• Abdominal pain or nausea and vomiting

How is Gastroscopy Performed?

Gastroscopy is typically performed as an outpatient procedure, and the patient is usually given a sedative to help them relax during the procedure. The doctor will:

1. Insert a flexible tube with a camera and light on the end (endoscope) through the mouth and into the esophagus
2. Guide the endoscope through the esophagus, stomach, and duodenum to visually examine the lining of these organs
3. Take tissue samples (biopsies) if necessary
4. Remove any polyps or other growths if present
5. Stop any bleeding if found

Preparation for Gastroscopy

To prepare for a gastroscopy, the patient should:

• Fast for at least 6-8 hours before the procedure to ensure the stomach is empty
• Avoid eating or drinking anything that may interfere with the procedure, such as antacids or medications that can affect bleeding
• Tell their doctor about any medications they are taking, including blood thinners and diabetes medications
• Remove any dentures or other oral appliances before the procedure

Risks and Complications of Gastroscopy

While gastroscopy is generally a safe procedure, there are some potential risks and complications to be aware of, including:

• Bleeding or perforation of the digestive tract
• Infection
• Allergic reaction to the sedative or other medications used during the procedure
• Damage to the teeth or mouth
• Reaction to the biopsy, such as bleeding or infection

After the Procedure

After a gastroscopy, the patient should:

• Rest for at least 1-2 hours after the procedure to allow the sedative to wear off
• Avoid eating or drinking anything for at least 1-2 hours after the procedure
• Avoid driving or operating heavy machinery for at least 24 hours after the procedure
• Follow any specific instructions provided by their doctor, such as taking medications to manage discomfort or bleeding

Results of Gastroscopy

The results of a gastroscopy are usually available immediately after the procedure. The doctor will:

• Discuss the findings with the patient, including any abnormalities or conditions found during the procedure
• Provide recommendations for further testing or treatment if necessary
• Explain the results of any biopsies taken during the procedure
