Today, tens of millions of endoscopies are carried out each year. In this article, we will explain some of the types of endoscopy, why and how they are performed, the general procedure, and any potential risks.
Capsule endoscopy was developed in the mids and involves a wireless camera. The camera is small enough to fit into a capsule roughly the size of a vitamin tablet and can, therefore, be swallowed.
As the capsule travels through the digestive tract, it takes thousands of pictures, which are transmitted to a device attached to a wearable belt. Capsule endoscopy is used to image the small intestine, a region that is difficult to image using standard endoscopy.
The capsule usually passes through the digestive system within hours. To date, more than , capsule endoscopy procedures have been carried out, and nearly 1, articles have been published covering its clinical use.
The procedure does not require an overnight stay in the hospital and usually only takes around 1 hour to complete. The doctor will provide instructions about the preparation for the procedure. For many types of endoscopy, the individual needs to fast for around 12 hours, though this varies based on the type. For procedures investigating the gut, laxatives may be taken the night before to clear the system.
A doctor will carry out an examination before the endoscopy. It is important to mention all current medications including supplements and any previous procedures. Sometimes, endoscopy will be combined with another procedure such as an ultrasound scan. Contact your doctor or go to the hospital if you experience severe abdominal pain, vomiting, or pass blood or have black bowel actions.
Long-term outlook Recovery time following endoscopy is rapid, usually a few hours to one day or so. Alternatives to endoscopy The main alternatives to endoscopy are x-rays for diagnostic procedures or open surgery for treatment procedures. Diagnoses of the gut may be made by swallowing x-ray contrast barium or having it passed into the rectum. The disadvantages of x-ray procedures include: An unpleasant taste or discomfort No biopsies can be taken for tissue diagnosis A therapeutic procedure such as removal of a polyp tumour cannot be performed at the same time.
The disadvantages of open surgery include: Longer hospital stay Increased risk of complications, including infection Longer convalescence recovery time Comparatively extensive scarring. Where to get help Your doctor The hospital or centre where the procedure was performed.

During a capsule endoscopy, you swallow a small pill with a tiny camera inside. The capsule passes through your digestive tract, without any discomfort to you, and creates thousands of images of the intestines as it moves through. Chromoendoscopy is a technique that uses a specialized stain or dye on the lining of the intestine during an endoscopy procedure.
EUS uses an ultrasound in conjunction with an endoscopy. A thin needle can then be inserted into the organ or structure to retrieve some tissue for viewing under a microscope. This procedure is called fine needle aspiration. EMR is a technique used to help doctors remove cancerous tissue in the digestive tract.
In EMR, a needle is passed through the endoscope to inject a liquid underneath the abnormal tissue. This helps separate the cancerous tissue from the other layers so it can be more easily removed. NBI uses a special filter to help create more contrast between vessels and the mucosa.
The mucosa is the inner lining of the digestive tract. Endoscopy has a much lower risk of bleeding and infection than open surgery. Still, endoscopy is a medical procedure, so it has some risk of bleeding, infection, and other rare complications such as:. For example, dark-colored stools , vomiting , and difficulty swallowing after a colonoscopy could indicate that something is wrong. A hysteroscopy carries a small risk of uterine perforation, uterine bleeding , or cervical trauma.
