Diagnostic and Therapeutic Procedures

Our staff offers the following diagnostic and therapeutic procedures to treat GI ailments and look for colorectal cancer:


Screening and Surveillance Colonoscopy

Colonoscopies save lives. These procedures are used to detect colon cancer. Colonoscopies are done under sedation and take about 30 minutes to complete. During the procedure your physician examines your lower digestive tract and may take biopsies or remove polyps in the large intestine.

Learn what to expect before, during and after the procedure in this video:

At Enloe, our staff is committed to prevention and early detection of cancers of the colon and rectum. They follow national screening and surveillance guidelines for appropriate and timely colonoscopy exams.

If you're scheduled for a colonoscopy with us, see how to prepare for your procedure.

Esophagogastroduodenoscopy (EGD)

Also known as upper GI endoscopy, esophagogastroduodenoscopy (EGD) is done under sedation to examine and take biopsies, if needed, of the esophagus, stomach and small intestine.

Your doctor will use an endoscope, a long, thin tool that has a light and camera at the end of it. This procedure can help find ulcers, infections and growths.

During this examination, your physician will guide the small device into your mouth, down your esophagus, and into your stomach and duodenum. 

If you have liver disease, your doctor may use an EGD exam to treat esophageal varices. Learn more about this procedure in the video below:

Video Capsule Endoscopy

During this in-office procedure, you will swallow a pill-sized capsule that will take pictures of your digestive system as it travels through you. 

These pictures are saved on  a recorder you wear, and the capsule leaves your body through your stool in about three days.

This test can help doctors see conditions, such as bleeding and tumors, that are hard to detect with other examinations. A video capsule endoscopy can also help diagnose Crohn’s disease, which causes inflammation, sores and narrowing of the bowel.

24-Hour pH Monitoring

24-hour pH monitoring measures the severity of acid reflux disease. During this procedure, your nurse will place a thin, plastic tube into your nostril, down your throat and into your esophagus.

At the end of the tube there is a sensor that measures acidity.

The other end of the tube will remain outside your body and will be connected to a monitor that records the pH levels for 24 hours.

During this time you should go about your normal daily routine once you leave the doctor's office. Be sure to keep record of any symptoms of reflux, or any activities that seem to trigger it.

Esophageal Motility Studies

This test measures how well your esophageal muscles and sphincter valve are functioning.

During this procure, your nurse will insert a tube through your nose and guide it into your stomach. Then it will be withdrawn slowly to measure the pressure changes.

You may be asked to take a few breaths with the tube inside you or you may be asked to take a few swallows of salty fluid to see how well your esophageal muscles are functioning.

The procedure lasts about 45 minutes and is not performed with sedation since this could affect how the esophageal muscles function.

Small Bowel Enteroscopy

This procedure is done under anesthesia and enables your physician to visualize the small bowel for bleeding, tumors, polyps or other issues.

If you have a small bowel enteroscopy, you will be given a sedative through an IV, and your doctor will insert an endoscope into your mouth. The tube will then be guided to your esophagus, stomach and small bowel, allowing your doctor to examine the area.

If the doctor finds growths or abnormalities, he or she may remove or biopsy the tissue in question. However, you will not feel this.

A  small bowel enteroscopy usually takes between 1 and 2 hours. Please note that you will not be able to drive after this procedure, so you should have someone accompany you to your visit.

Endoscopic Submucosal Dissection

Endoscopic Submucosal Dissection (ESD) is a highly advanced endoscopic procedure used to remove premalignant and early-stage lesions of the stomach, esophagus, and colorectum.

During this procedure, a long, narrow tube is passed through the throat to reach a stomach lesion, or the tube is passed through the anus to reach a lesion in the colon. Small amounts of fluid are injected into the areas of dysplasia (damaged cells) and diseased tissue is carefully removed.

To prepare for your procedure, you should not eat or drink anything 8 hours before your ESD if the tumor is located in your stomach. If it is located in your colon, you'll be given a prescription to prepare your colon.

An overnight hospital stay may be required when you have this procedure. The following day you will have an upper endoscopy, at which time your doctor will evaluate the dissection sites for any complications.


Barrx, or barrx ablation, is a procedure used to treat Barrett’s esophagus, a condition that can result from having chronic heartburn or gastroesophageal reflux disease (GERD).  It is performed during an upper endoscopy and uses radiofrequency energy to destroy abnormal cells.

Terminating these cells can prevent the tissue from developing into cancer. Once the abnormal cells are destroyed, new healthy cells can replace them.

If you are going to have a barrx ablation, you will not be allowed to eat or drink anything 8 to 12 hours before the procedure. During the procedure, you will lie on your side and a tube will be inserted into the esophagus to deliver energy to the abnormal tissue.

It is important that you continue with your treatment for GERD on a long-term basis as advised by your doctor to prevent further damage to the lining of the esophagus.


Cholangioscopy is used when X-ray imaging from an ERCP is insufficient to diagnose or treat problems in the bile and pancreatic ducts. Used in conjunction with ERCP, cholangioscopy allows your doctor to directly visualize and examine these ducts to diagnose, take tissue samples and, in many cases, treat bile duct stones, gallstones, and narrowing or blockage of the liver ducts.

It is also a vital diagnostic tool for confirming or ruling out cancer of the biliary tract.

During the procedure, you will be sedated and lie on your left side. A small endoscope will then be passed through a traditional endoscope (a flexible, lighted scope) down the esophagus into your biliary tract.

To prepare for your procedure, you should not eat or drink anything 8 to 12 hours prior to your procedure. You'll need to make plans to have someone take you home.

Fecal Microbiota Transplantation (FMT)

Fecal microbiota transplantation (FMT) is used to treat clostridium difficile (C. diff) infections, which affect the intestinal tract. These infections can cause a range of symptoms, from mild diarrhea to severe inflammation of the large intestine.

During this procedure, your doctor will transplant healthy stool from a donor into your colon through a colonoscopy, endoscopy, sigmoidoscopy or enema. This procedure is used to replace good bacteria that has been killed or harmed usually from the use of antibiotics. 

Hemorrhoidal Banding

Your doctor may use hemorrhoidal banding to treat internal hemorrhoids. Hemorrhoid tissues actually play an important role in eliminating waste. During bowel movements, hemorrhoids swell with blood and become larger to protect the anal canal as stool passes. Then the tissues return to their normal size.

However, pressure can cause hemorrhoid tissues to remain swollen. If this happens, your doctor may perform hemorrhoidal banding endoscopically or in the outpatient clinic to remove any internal hemorrhoids you may have.

During this procedure, your doctor will tie off the hemorrhoids at their base, cutting off blood flow to the hemorrhoids so they will shrink and die.
