Endoscopy Procedures

Upper Endoscopy

Upper endoscopy allows a physician to examine the lining of the upper part of your gastrointestinal tract, which includes the esophagus, stomach and duodenum (first portion of the small intestine). A physician will use a thin, flexible tube called an endoscope, which has its own lens and light source, and will view the images on a video monitor. You might hear the physician or other medical staff refer to upper endoscopy as upper GI endoscopy, esophagogastroduodenoscopy (EGD) or panendoscopy.

Capsule Endoscopy

Capsule Endoscopy enables the examining of the duodenum, jejunum, ileum of your small intestine. A physician will use a vitamin-pill sized video capsule as an endoscope, which has its own camera and light source. While the video capsule travels through your body, images are sent to a data recorder you will wear on a waist belt. Most patients consider the test comfortable.


Colonoscopy is well-tolerated and rarely causes much pain. You might feel pressure, bloating or cramping during the procedure. Your may receive a sedative to help you relax and better tolerate any discomfort. Before colonoscopy you will be given a mild sedative and sometimes a painkiller as well. The instrument is passed via the anus and examination of the entire colon is usually possible. The examination is usually straightforward and takes less than 30 minutes to complete. Any abnormal areas are identified and tissue samples may be taken via the instrument. Any polyps can often be removed at the time of the examination.


For flexible Sigmoidoscopy, there is usually no sedation or pain killer required and the examination will usually take about ten minutes.
