Endoscopy Laboratories

The Endoscopy Laboratory is located at the General Surgery & Endoscopy Center. DMA General Surgeons regularly perform the following procedures on-site:

Upper Endoscopy (EGD) – A flexible fiber optic scope is inserted through the mouth to look at a patient’s stomach and esophagus for abnormalities. The anesthetist uses IV medications to sedate the patients. This procedure is used for swallowing problems, stomach pain, ulcers and removing foreign objects.

Colonoscopy – After IV sedation, a flexible fiber optic scope is inserted in the colon and is used by the physician to view the entire large intestine and where the large and small intestine meets. Patients follow a special diet for a day before the procedure to cleanse the colon and are sedated during the colonoscopy.

This procedure can be a screening for colon cancer or to check for diverticulosis (pockets in the colon), colitis or illness than produce altered bowel habits, as well as polyps (growths that can be pre-cancerous or cancerous). When polyps are found, they are removed during the colonoscopy and are sent to a laboratory to check for cancer. If other abnormalities are found they can usually be biopsied and sent to be analyzed on the same day.

Sigmoidoscopy – Are most often used as a screening tool to check for colon cancer and polyps for people less than 50 years of age, and without a family history of colon cancer. It can also be used to check for diverticulosis (pockets in the colon), hemorrhoids, and other rectal illness.

A flexible fiber optic scope is inserted into the colon and is used by the physician to view the sigmoid portion of large intestine.

Small Bowel Capsule Endoscopy – This procedure enables the physician to examine your entire small intestine. Your physician will have you ingest a vitamin-pill sized video capsule, which has its own camera and light source. During the 8 hour exam, you are free to move about. While the video capsule travels through your body, it sends images to a data recorder you will wear on a waist belt. Most patients find the test comfortable. Afterwards your doctor will view the images on a video monitor. Capsule endoscopy helps your doctor determine the cause for recurrent or persistent symptoms such as abdominal pain, diarrhea, bleeding or anemia.

Bravo pH monitoring system– A minimally invasive test for heartburn or GERD (Gastroesophageal Reflux Disease). The test involves a miniature pH capsule, approximately the size of a gel cap that is attached to your esophagus. Throughout the test period, the Bravo pH capsule measures the pH in the esophagus and transmits this information to a pager-sized receiver worn on your belt or waistband just like a pager or mobile phone. You will be given a diary to write down the times when you have reflux symptoms (for example, coughing, heartburn, regurgitation). After the test is completed, you return the diary and the Bravo Receiver to your physician. The test data is then uploaded to a computer, and analyzed by your doctor to diagnose your condition.
