Endoscopy

What is an endoscopy?

An endoscopy, also called an upper endoscopy, is a diagnostic procedure that evaluates the upper part of your digestive system, which includes your esophagus, stomach, and duodenum (the first portion of your small intestine). 

During the procedure, Dr. Lau uses a lighted, flexible tube called an endoscope to evaluate the tissue. 

JKAN Gastroenterology PLLC also offers the capsule endoscopy. During the minimally invasive test, you swallow a special pill with a camera that takes pictures of your intestines as it travels through the length of your digestive system. 

Why would I need an endoscopy?

Dr. Lau may recommend an endoscopy for a number of reasons. You may benefit from the diagnostic procedure to detect:

• Ulcers
• Abnormal growths
• Precancerous conditions
• Bowel obstruction
• Inflammation
• Hiatal hernia
• Gastric reflux
• Bleeding in the upper gastrointestinal tract
• Barrett’s esophagus
• Celiac disease
• Crohn’s disease

She may also recommend an upper endoscopy to find the cause of your gastrointestinal symptoms, such as abdominal pain, nausea and vomiting, or swallowing difficulties. Dr. Lau may also recommend it if you have anemia or unexplained weight loss. 

How do I prepare for an endoscopy?

The team at JKAN Gastroenterology PLLC provides written instructions on how to prepare for your endoscopy. The goal of your preparation is to clear out all food and debris from your upper digestive system.

Your preparation may require you not to eat or drink for up to eight hours prior to the procedure. You may also be asked not to smoke or chew gum during this time.

Dr. Lau may also request that you modify your usual medication and supplement schedule to minimize the risk of bleeding. 

You cannot drive for up to 24 hours after upper endoscopy, and the team requests that you also arrange to have someone drive you home after the procedure. 

What happens during an endoscopy?

The upper endoscopy is an outpatient procedure performed under sedation. During the procedure, Dr. Lau inserts the endoscope into your mouth and through your esophagus, stomach, and duodenum.

The endoscope transmits video images of the tissue, allowing Dr. Lau to look for signs of abnormalities, which she biopsies to confirm or rule out a diagnosis. 

After your endoscopy, you’re taken to the recovery area until the sedative wears off. Dr. Lau reviews the preliminary findings of your endoscopy and schedules a follow-up appointment if needed to develop your treatment plan.
