Introduction to Gastroenterology

Gastroenterology is the area of medicine that deals with the digestive system and how our bodies break down food so it can be absorbed by our intestines to fuel the rest of our body. A gastroenterologist is a doctor who specializes in the digestive system. The Introduction to Gastroenterology video explores the basic anatomy of the esophagus, stomach, small intestine, large intestine (colon). It also explains why you might need to see a gastroenterologist.

EGD / Upper Endoscopy
What is upper endoscopy?

Upper endoscopy lets your doctor examine the lining of the upper part of your gastrointestinal tract, which includes the esophagus, stomach and duodenum (first portion of the small intestine). Your doctor will use a thin, flexible tube called an endoscope, which has its own lens and light source, and will view the images on a video monitor. You might hear your doctor or other medical staff refer to upper endoscopy as upper GI endoscopy, esophagogastroduodenoscopy (EGD) or panendoscopy.

Colonoscopy
What is a colonoscopy?

Colonoscopy enables your doctor to examine the lining of your colon (large intestine) for abnormalities by inserting a flexible tube as thick as your finger into your anus and slowly advancing it into the rectum and colon. If your doctor has recommended a colonoscopy, this brochure will give you a basic understanding of the procedure – how it’s performed, how it can help, and what side effects you might experience. It can’t answer all of your questions since much depends on the individual patient and the doctor. Please ask your doctor about anything you don’t understand.

Capsule Endoscopy
What is Capsule Endoscopy?

Capsule Endoscopy lets your doctor examine the lining of the middle part of your gastrointestinal tract, which includes the three portions of the small intestine (duodenum, jejunum, ileum). Your doctor will give you a pill sized video camera for you to swallow. This camera has its own light source and takes pictures of your small intestine as it passes through. These pictures are sent to a small recording device you have to wear on your body.

Your doctor will be able to view these pictures at a later time and might be able to provide you with useful information regarding your small intestine.

ERCP
What is ERCP?

Endoscopic retrograde cholangiopancreatography, or ERCP, is a specialized technique used to study the bile ducts, pancreatic duct and gallbladder. Ducts are drainage routes; the drainage channels from the liver are called bile or biliary ducts. The pancreatic duct is the drainage channel from the pancreas.

Endoscopic ultrasonography (EUS)
What is EUS?

Endoscopic ultrasound (EUS) allows your doctor to examine your esophageal and stomach linings as well as the walls of your upper and lower gastrointestinal tract. The upper tract consists of the esophagus, stomach and duodenum; the lower tract includes your colon and rectum. EUS is also used to study other organs that are near the gastrointestinal tract, including the lungs, liver, gall bladder and pancreas.

Endoscopists are highly trained specialists who welcome your questions regarding their credentials, training and experience. Your endoscopist will use a thin, flexible tube called an endoscope that has a built-in miniature ultrasound probe. Your doctor will pass the endoscope through your mouth or anus to the area to be examined. Your doctor then will use the ultrasound to use sound waves to create visual images of the digestive tract.
