Some issues Dr. Xiang-Yang Y. David Guo, MD, PhD can help you with:

Colonoscopy

Colonoscopy is the use of a special tool called a colonoscope (a thin, flexible tube with a camera on the end) to examine the inside of the colon and rectum. The tube is typically inserted anally, and it allows the physician to examine the large intestine from the inside. It may be done at any time to diagnose bowel problems, but routine colonoscopies are advised after the age of 50 to screen for colon cancer.

A colonoscopy may be performed to diagnose:

Intestinal ulcers
Polyps
Bowel cancer
An unidentified source of pain or bleeding in the intestine

Patients may be asked to drink only liquids in the days before a colonoscopy, or they may be given an enema to remove residual fecal matter. Before the exam, patients are given medication to help them relax, and then lay on their side on a table. The scope is inserted into the anus and gently moved all the way through the large intestine. Air may be pumped into the intestine to improve the view for the physician. Any polyps that are found will be removed. Then the colonoscope will be withdrawn. A colonoscopy is not usually painful, but patients may feel some bloating or have some cramps right afterward. If patients have polyps removed, they might experience a small amount of bleeding. Any side effects should go away within a few hours.

Enteroscopy

Enteroscopy visually examines the small bowel and identifies such issues as bleeding, tumors, polyps, ulcers, and swollen lymph nodes. Common reasons this exam may be ordered are abnormal X-ray results and unexplained diarrhea.

Enteroscopies may be used alone or in combination with other procedures. For example, if a doctor suspects malignancy (cancer) in the small bowel, she may use an enteroscope to take a sample of tissue from the small bowel and have it examined in a laboratory. If there is a blockage in the small intestine that cannot be surgically removed, an enteroscopy-guided stent placement may help relieve some of the symptoms associated with the obstruction. Enteroscopes may also be used to treat intestinal bleeding and remove abnormal growths like tumors and polyps, as well as foreign objects that might have found their way into the small bowel.

There are several ways to perform an enteroscopy:

Push enteroscopy involves the use of a long tube with a camera, called an enteroscope. Depending on the location of the problem, the enteroscope is either passed through the mouth or rectum. This technique is often used to detect and stop bleeding in the upper small intestine.
Balloon enteroscopy uses scopes that have tiny balloons at the tip. The balloons inflate and deflate to help make the passage of the scope into the small bowel easier. This method is used when there is a need to access and treat certain parts of the small intestine that push enteroscopy cannot reach.
Capsule enteroscopy involves swallowing a capsule with a tiny camera inside it. As the capsule travels through the small intestine, the camera records and sends images that are then downloaded and analyzed by the doctor. The capsule eventually leaves the body during bowel movement. If the doctor needs to visualize the entire small intestine, capsule enteroscopy is the only option. The only drawback to this technique is that it cannot be combined with any treatment.

Enteroscopy is typically performed at the doctor's office and takes about 20 to 30 minutes, but may take longer if combined with another procedure. Patients may have a sore throat for a few hours if the scope was inserted through the mouth. Normal activities may be resumed about 24 hours following enteroscopy.
