GI / Endoscopy Services
Northwest Tucson Surgery Center provides gastrointestinal procedures for screening purposes and treatment of existing conditions. The two most common procedures performed are colonoscopy and an upper GI endoscopy, commonly referred to as EGD (Esophogastroduodenoscopy). Your primary care physician will help determine if you are a candidate for either procedure.
Colonoscopy
A colonoscopy is the visual examination of the large intestine (colon) to identify and/or correct a problem using a lighted, flexible video endoscope. The video endoscope uses a tiny, optically sensitive computer chip at the end. Electronic signals are then transmitted up the scope to a computer, which displays the image on a large video screen. There is an open channel in the scope that allows other instruments to be passed in order to perform certain procedures, such as polyp removal and biopsy to obtain small tissue samples for microscopic analysis. Directly viewing the inside of the colon by colonoscopy is usually the best exam. The test enables a diagnosis to be made and specific treatment provided.
A colonoscopy can be performed on an outpatient basis using mild sedation, and all patients will require a ride to and from Northwest Tucson Surgery Center. The procedure takes 15 to 30 minutes. Following the colonoscopy, patients will remain in a recovery area to monitor vital signs until fully awake. It is normal to experience mild cramping or abdominal pressure following the exam.
Preparation for the exam varies based on physician preference, but usually involves drinking a solution to flush the colon clean or taking laxatives and enemas. For clear visualization of the large intestine, preparation must be completed as prescribed.
Upper GI Endoscopy
Upper GI endoscopy, sometimes called EGD, is a visual exam of the upper intestinal tract using a lighted flexible video endoscope. EGD allows the physician to visualize the esophagus, the stomach and the entrance into the small intestine known as the duodenum.
The flexible endoscope can be directed and moved around the many bends in the gastrointestinal tract. The endoscope has a tiny, optically sensitive computer chip at the end. Electronic signals are then transmitted up the scope to the computer, which then displays the image on a large video screen. An open channel in these scopes allows other instruments to be passed through in order to take tissue samples, remove polyps and perform other exams.
A UGE is performed on an outpatient basis primarily to identify and/or correct a problem in the upper gastrointestinal tract. The exam takes from 15 to 30 minutes after which time the patient is taken to the recovery area. All patients will require a ride to and from Northwest Tucson Surgery Center on the day of the exam, as driving is prohibited for 24 hours after the administration of the sedatives.
It is important not to eat or drink anything for at least eight hours before the exam. Your physician will instruct you about the use of regular medications, including blood thinners before your exam.
GERD
Gastroesophageal reflux disease, or GERD, is a serious heartburn brought on by the esophagus being constantly exposed to stomach acid, which irritates the lining. The esophagus is the muscular tube that connects the throat to the stomach. Heartburn is that burning sensation felt behind the breastbone and sometimes in the neck and throat. Occasional heartburn is nothing to be concerned about; however, anyone who has heartburn on a regular basis should consult a physician. An endoscopy is the most important test for patients with GERD.
Lifestyle changes can help and there are many medications that can be used to treat GERD. A good medical program can contribute to a successful treatment.
Patient results may vary. Consult your physician about the benefits and risks of any surgical procedure or treatment.
