2. What is an Upper Endoscopy (EGD)?

EGD or an upper endoscopy is a procedure in which the first part of your small intestine (duodenum), stomach, and esophagus are viewed with the help of a thin, flexible tube containing a camera. It is as though a small light, soft robot is sent into your body. Your doctor can view inflammation, ulcers, tumors or bleeding by using the camera because it provides a real-time video.

With an EGD we can see crystal-clear, high quality images, according to Dr. Bharat Pothuri. It is not so invasive as surgery and it gives quick answers to the patients of upper GI symptoms.

3. When will you require an EGD procedure?

Being aware of your need to have an EGD procedure can make you receive the care you need when you need it. The following are typical causes of doctors in Houston or elsewhere suggesting upper endoscopy:

• Chronic Heartburn ((GERD)) - When the acid reflux does not respond to diet or medicine.
• Difficulty Swallowing (Dysphagia) - To detect strictures, rings, or motor problems.
• Abdominal Pain- This could be persistent without imaging explanation.
• Bleeding Signs- Anemia, black stools or vomited blood (hematemesis)
• Unexplained Loss of weight - In order to exclude cancer or severe inflammation.
• Constant Nausea or Vomiting - When basic tests are reported normal.

At what point are you required to do an EGD? Should your gastroenterologist be suspicious of something serious such as the esophagus of Barrett or a bleeding ulcer an upper endoscopy is usually the quickest method to detect and cure the problem, notes Dr. Pothuri.

4. A Step-by-step Guide to an Endoscopy.

Knowing the step by step working of an endoscopy can calm you down. The following is the average flow in a Houston outpatient center or hospital:

Step 1: Consultation

You get to see your gastroenterologist. You talk about symptoms, medical history and medications.

Step 2: Prep Instructions

• None of the solid food 6-8 hours before.
• Crystallized until two hours previous.
• Stop anticoagulant when ordered.

Step 3: Arrival and Check-In

• Sign consent forms.
• Change into a gown.
• An IV is placed for sedation.

Step 4: Sedation and Positioning

• You lie on your side.
• Sedatives and/or local throat spray make you feel good.

Step 5: Insertion of the Endoscope

• The scope is carefully inserted in your throat by the doctor using your mouth.
• You breathe without difficulty as the range of view moves down your esophagus, stomach and duodenum.

Step 6: Image Capture and Biopsy

• The camera transmits live video to a display.
• The doctor takes biopsies (small pieces of tissue), or medicines the bleeding, using small tools, where necessary.

Step 7: Completion and Recovery

• The breadth is pulled back.
• You sleep until the sedation has lost its effect (80-120 minutes or so).
• Your vital check and post-care instructions is performed by a nurse.

5. Diagnosis What is the Diagnosis of an Upper Endoscopy (EGD)?

The question most people ask is, what is diagnosed through an upper endoscopy (EGD)? Here's a breakdown:

• Esophagitis and GERD damage
• Barretts esophagus (pre-cancer)
• Stomach or duodenum peptic ulcers
• Inflammation of the stomach lining (gastritis)
• Hiatal hernia
• Celiac disease alters (through duodenal biopsy)
• Benign or malignant upper GI tumor
• Esophagus or stomach varices (enlarged veins)
• Mallory-Weis tears (tears of the esophageal lining)
• Removal of foreign bodies (e.g., coins swallowed)

Dr. Pothuri says that an EGD is a powerful diagnostic tool because it allows us to look directly at the esophagus, stomach, and upper small intestine. It can help identify inflammation, ulcers, narrowing, bleeding, reflux-related changes, or other concerns. When needed, we can also take small tissue samples during the procedure and send them for microscopic review. This helps confirm the diagnosis and guide the right treatment plan.
