Colonoscopy

A colonoscopy is now the gold standard used to detect or prevent individuals from getting colon cancer. Adults starting at age 45 years are strongly recommended to have a colonoscopy or some other test to screen for colon cancer.

Capsule Endoscopy

During the procedure, a patient swallows a vitamin-sized pill with a camera inside (pill camera). Transported smoothly and painlessly through the GI tract by the body’s own natural peristalsis, the video pill capsule transmits images of different parts of your intestine, such as the small intestine and the esophagus.

ERCP

An endoscopic retrograde cholangiopancreatography, more commonly known as ERCP, is an endoscopic procedure that is also combined with X-rays. ERCP is very much like a typical upper GI endoscopy; however, your gastroenterologist will inject a dye during the procedure, which highlights problems in certain digestive organs through X-ray technology.

Flexible Sigmoidoscopy

A sigmoidoscopy is an internal exam of the lower part of the large intestine (colon) using a short, thin, flexible, lighted tube with a camera at the tip. This procedure helps determine the cause of abdominal pain, rectal bleeding, changes in bowel habits, chronic diarrhea, and other intestinal problems.

Hemorrhoid Treatments

Two of the most common treatments for hemorrhoid removal are hemorrhoid banding, which cuts off blood flow to the hemorrhoid, and infrared coagulation (IRC) therapy, which uses infrared light to shrink and shrivel hemorrhoids. The treatment method depends highly upon whether the hemorrhoids are external (around the anus) or internal (in the rectum).

Upper Endoscopy

An endoscopy is a very common and safe procedure that is used to examine the esophagus, stomach, and upper part of the small intestine, known as the duodenum, to get a closer look at what may be causing symptoms.

Celiac Disease

Celiac disease is an autoimmune disease where a patient’s immune system abnormally responds to the ingestion of gluten. It is estimated that 1 in 100 people worldwide is affected by celiac disease. However, up to 2.5 million people in the United States may have celiac disease and not know it, as the symptoms range from mild to severe.

Constipation

Constipation is defined as having a bowel movement fewer than three times per week. With constipation, stools are usually hard, dry, small in size, and difficult to eliminate. Some people who are constipated find it painful to have a bowel movement and often experience straining, bloating, and the sensation of a full bowel.

GERD

Gastroesophageal reflux disease (GERD) is a more serious form of gastroesophageal reflux (GER) which is common. GER occurs when the lower esophageal sphincter (LES) opens spontaneously, for varying periods of time, or does not close properly, and stomach contents rise up into the esophagus.

Hemorrhoids

Hemorrhoids are swollen veins in the anal canal. This common problem can be painful and can be caused by too much pressure on the veins in the pelvic rectal area. Normally, tissue inside the anus fills with blood to help control bowel movements, but if you strain or sit on the toilet a long time to move stool, the increased pressure causes the veins in this tissue to swell and stretch.

Inflammatory Bowel Disease + Crohn's Disease & Ulcerative Colitis

Inflammatory bowel disease (IBD) encompasses a set of gastrointestinal diseases where parts of the digestive tract are chronically inflamed by a dysfunctional interaction immune system. Hereditary factors and an abnormal interaction between microorganisms and the immune system are felt to play a role.

Irritable Bowel Syndrome

It is estimated that 10 to 15 percent of Americans have Irritable Bowel Syndrome (IBS). IBS is a functional GI disorder that refers to a group of symptoms that affect the digestive tract, often resulting in abdominal pain, bloating, or cramping. However, some people with IBS have no symptoms at all.
