We offer a variety of testing options to diagnosis and treat the diseases of the gastrointestinal tract. Our specially trained staff are committed to your care and comfort.


Upper endoscopy enables your ADH physician to look inside the esophagus, stomach, and duodenum (upper portion of the small intestine). This procedure can be used to diagnose the cause of swallowing difficulties, chronic nausea, vomiting, reflux, bleeding, indigestion, abdominal pain, or chest pain. Upper endoscopy is also called an EGD.

The endoscope transmits an image of the inside of the esophagus, stomach, and duodenum, so the physician can carefully examine the lining of these organs. The scope also blows air into the stomach; this expands the folds of tissue and makes it easier for the physician to examine the stomach.

The physician can see abnormalities, like inflammation or bleeding, through the endoscope that aren’t clearly visible on x-rays. The physician can also insert instruments into the scope to remove samples of tissue (biopsy) for further tests or to treat bleeding abnormalities.

You may experience a mild sore throat after the procedure. The staff will give you all the information you will need to make an informed decision; as well as everything you need to prepare for your EGD. The procedure takes 15 to 30 minutes. Because you will likely be sedated, you will need to rest at the endoscopy facility for 1 to 2 hours until the medication wears off.

Flexible sigmoidoscopy enables the physician to look at the inside of the lower one-third of the colon, called the sigmoid or descending colon. With flexible sigmoidoscopy, your ADH physician can see bleeding, inflammation, abnormal growths, and ulcers in the descending colon and rectum. Flexible sigmoidoscopy is not sufficient to detect polyps or cancer in the ascending or transverse colon (two-thirds of the colon).

Flexible sigmoidoscopy takes 10 to 20 minutes. During the procedure, you might feel pressure and slight cramping in your lower abdomen. You will feel better afterward when the air leaves your colon.


ERCP is a procedure that enables the physician to diagnose problems in the liver, gallbladder, surrounding bile ducts, and pancreas. If the exam shows a gallstone or narrowing of the ducts, the physician can insert instruments into the scope to remove or relieve the obstruction. Also, tissue samples can be taken for further testing.

ERCP normally can take as little as 30 minutes or up to 2 hours. You may have some discomfort when the physician blows air into the duodenum and injects the dye into the ducts, but your pain will be managed by your ADH team.


Endoscopic Ultrasound (EUS) allows your doctor to examine the lining and the walls of your upper and lower gastrointestinal tract. The upper tract is the esophagus, stomach and duodenum; the lower tract includes your colon and rectum. EUS can also used to study internal organs that lie next to the gastrointestinal tract, such as the gall bladder and pancreas.

EUS provides your doctor more detailed pictures of your digestive tract anatomy. Your doctor can use EUS to diagnose the cause of conditions such as abdominal pain or abnormal weight loss. In addition, an EUS can also used to evaluate a previously detected abnormality. Because an EUS provides a very detailed picture of the abnormality, they can be extremely helpful to your doctor in determining its nature and decide upon the best treatment.

In addition, EUS can be used to diagnose diseases of the pancreas, bile duct and gallbladder when other tests are inconclusive.


PEG stands for percutaneous endoscopic gastrostomy, a procedure in which a flexible feeding tube is placed through the abdominal wall and into the stomach. PEG allows essential nutrition, fluids and/or medications to be put directly into the stomach, bypassing the mouth and esophagus. It is only used When disease or circumstance interferes with the body getting the nutrients that it needs.

If you, or a loved one, needs a PEG procedure your ADH physician will carefully explain the procedure - both benefits and potential risks - and answer any questions you might have.


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 use a pill sized video capsule called an endoscope, which has its own lens and light source and will view the images on a video monitor.

The most common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine. It may also be useful for detecting polyps, inflammatory bowel disease (Crohn’s disease), ulcers, and tumors of the small intestine.
