What is an endoscopy?

AnEndoscopyis a procedure where the surgeon uses specialized instruments to examine and operate on the bodys internal organs and vessels. It helps doctors to see issues inside the body without making large incisions. A surgeon inserts an endoscope through a small cut or a natural opening in the body. An endoscope is a flexible tube with a camera attached to it that lets your doctor see. Your doctor can control forceps and scissors at the end of the endoscope, to performBiopsyoperations.

Why do I need an endoscopy?

To screen for cancer, and prevent it:

For example, doctors use a type ofEndoscopyto test colorectal cancer, called a colonoscopy. Your doctor may remove growths, called polyps, during a colonoscopy. Without removal, polyps may lead to cancer.

To treat determine the cause of the symptoms:

The type ofEndoscopyrecommended by your doctor is dependent on the part of the body being examined.

To give treatment:

Doctors use endoscopes for certain treatments. Treatments possibly involving an endoscope include:

• Laparoscopic surgery:Done through small incisions in the skin
• Laser therapy:Uses a powerful beam of light to destroy cancer cells
• Microwave ablation: Uses heat to destroy cancerous tissue
• Endoscopic mucosal resection:Surgeryusing an endoscope inserted into the gastrointestinal tract
• Photodynamic therapy:To destroy a tumor with a laser after injecting it with a light-sensitive substance
• Medication delivery:To administer any medication directly at the site of the disease.

The doctor will confirm the symptoms, do a physical exam, and probably orderBlood TestsbeforeEndoscopy. Such assessments will help your physician gain a greater understanding of the potential cause of your symptoms. These tests may also help them determine whether they can treat the problems withoutEndoscopyorSurgery.

How is an Endoscopy performed?

The doctor puts the endoscope into your mouth. He or she can ask you to swallow, as the scope passes through your throat. You may feel some pressure in your throat but you do not necessarily experiencePain. Once the endoscope passes your throat you cannot speak, but you can make noises. The endoscope should not mess with the respiration.

A small camera at the tip transmits pictures to the video display. Your doctor will watch the monitor look into your digestive tract for abnormalities. If there are abnormalities in your digestive tract, your doctor can record pictures for subsequent tests. Gentle air pressure can be injected into the esophagus to inflate the digestive tract. This allows free movement of the endoscope. It helps the doctor to inspect the folds of the digestive tract more easily. Your doctor can pass special surgical equipment through the endoscope to retrieve a tissue sample or remove a polyp, if necessary. Your doctor will use the video display to direct and control the devices. The endoscope is slowly retracted through your mouth after your doctor has finished the exam. Depending on the case, anEndoscopyusually requires about 15 to 30 minutes.
