Endoscopy Center Pune - Inamdar Multispeciality Hospital
Endoscopy means looking inside the body for medical reasons using an endoscope, an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ. Endoscopy can also refer to using a borescope in technical situations where direct line-of-sight observation is not feasible. An upper GI endoscopy is done in patients having problems in swallowing, frequent heartburn, abdominal pain, chest discomfort, vomiting especially of blood or abnormal findings on gastrointestinal X-rays. Colonoscopy is performed on patients passing blood in the stools, to check for colon cancer and to remove precancerous lesions such as polyps.
As an alternative to endoscopy, barium contrast X-rays may be done which use a contrast medium (barium) to highlight the intestinal tract on X-rays. There is minimal risk that the endoscope may injure or puncture some part of your body. For more specific risks related to a particular type of endoscopy, check with your doctor. Endoscopy helps the doctor to make a more accurate diagnosis of diseases of the gastrointestinal tract. In addition, endoscopy can be used to provide treatment like removing foreign bodies, benign tumors such as polyps, opening up of strictures, removing obstructed gallstones and stopping active bleeding from ulcers or from dilated veins called varices.
What is Capsule Endoscopy?
Capsule endoscopy is used to see the area inside your small intestine, which is not easily reachable with the help of traditional endoscopy procedures. Traditional endoscopy such as colonoscopy or esophagogastroduodenoscopy involves passing a long, flexible tube equipped with a video camera down your throat or through your rectum.
Capsule endoscopy procedure uses a wireless camera, which is same as the size and shape of a pill. After you swallow the capsule, it takes thousands of pictures on the inside of the gastrointestinal tract that is transmitted to a recorder you wear on a belt around your waist.
Your doctor will direct you to the capsule endoscopy preparations. You have to stop eating and drinking at least 12 hours before the procedure. Your doctor might ask you to start or stop certain medications. You may be asked to take a laxative before your capsule endoscopy to flush out your small intestine.
Your doctor will watch the video made by special software that strings the images together with the help of a computer and share the results of capsule endoscopy. Capsule endoscopy is a very safe diagnostic method. However, there are very few chances of capsule endoscopy side effects such as abdominal pain, distension, and nausea.!
What Happens During Capsule Endoscopy?
The diagnostic procedure is almost as simple as swallowing a pill the size of a large vitamin tablet, but this capsule contains lights, a wireless transmitter and a camera housed in clear plastic. Your doctor will fit you with a monitoring device to wear as the pill moves through you. Some monitors are connected to adhesive patches the doctor will place on your abdomen. For the next 8 to 12 hours, you will wear the monitoring device as the capsule moves slowly through your gastrointestinal tract.
You will not feel any unusual sensations during the test, but the camera you have swallowed will be working overtime. During a typical test, the camera takes about 50,000 pictures of your stomach and intestinal walls. Like a camera flash, the LED lights in the capsule provide light for the images the camera takes and transmits to the compact monitoring device you wear.
After the wireless camera completes its tour of your stomach, small intestine and colon, it is expelled. The capsule may emerge after a few hours, or it may not make its reappearance for up to 72 hours; both possibilities are normal. The camera is disposable and can be flushed, so you do not need to retrieve it. The information it gathered is stored in the monitoring device, not the capsule.
Advantages of Capsule Endoscopy
Because you need no anaesthesia for capsule endoscopy, the procedure involves no recovery time. For many patients, swallowing a pill is considerably more pleasant than undergoing conventional endoscopy. The middle portions of your gastrointestinal tract are difficult to see by other means, but capsule endoscopy creates a detailed, up-to-date image of your intestinal lining. Conditions that can be challenging to diagnose by other means are often readily revealed by capsule endoscopy.
