An endoscopy is the insertion of a thin, long tube directly into a body opening, such as the mouth or anus, to examine tissue or an internal organ in detail. The procedure can also be used to carry out other tasks, including minor surgery and imaging.
Dr Webner may recommend an endoscopy to diagnose symptoms or find the causes for certain digestive complaints. The procedure can be used to test for any abnormalities or infections in a particular vessel or organ, as well as to detect precancerous and cancerous growths.
A sigmoidoscopy procedure lets Dr Webner examine a portion of the colon and the lining of the rectum. The procedure involves inserting a flexible tube into the anus and slowly advancing it into the rectum and lower part of the colon. A sigmoidoscopy evaluates the lower third of the colon. The procedure is often done without any sensation, although sedation is used when necessary.
An ERCP is a special technique used to diagnose and treat problems of the liver, pancreas and, on occasion, the gallbladder. To reach the small passageways that connect these organs, an endoscope is passed through the mouth, past the stomach and into the small intestine.
An EGD is an endoscopic procedure that diagnoses and treats conditions related to the upper gastrointestinal tract. During the procedure, an endoscope is inserted into the mouth and guided through the pharynx to the oesophagus; then, it passes through the stomach and intestines.
A EUS is a procedure in which a flexible endoscope has a small ultrasound device built into a video camera to view the wall and lining of the stomach, small bowel, colon or oesophagus. Endoscopic ultrasound examinations ( may be performed through the mouth or through the anus. EUS is performed under sedation.
After you have an endoscopy, you will stay in the clinic or hospital for 1 to 2 hours to allow the medication to wear off. You'll be able to go home after your doctor or nurse checks to make sure that you're not having any problems.
You might have to stay overnight if you had treatment during the test. Some people have a sore throat for a day or two after the procedure. If you have a sore throat, you can use an over-the-counter spray to numb your throat.
You should be able to resume your daily activities the day after the test. Rest enough and follow Dr Webner's directions for eating after the test. Drink plenty of fluids (unless Dr Webner has advised you not to).
