Definition of endoscopy

An endoscopy is a procedure in which your doctor uses specialized instruments to view and operate on the internal organs and vessels of your body. It allows surgeons to see problems within your body without making large incisions.

A surgeon inserts an endoscope through a small cut or an opening in the body such as the mouth. An endoscope is a flexible tube with an attached camera that allows your doctor to see. Your doctor can use forceps and scissors on the endoscope to operate or remove tissue for biopsy.

 

Why do I need an endoscopy?

Endoscopy allows your doctor to visually examine an organ without having to make a large incision. A screen in the operating room lets the doctor see exactly what the endoscope sees.

Endoscopy is typically used to:

• help your doctor determine the cause of any abnormal symptoms you’re having
• remove a small sample of tissue, which can then be sent to a lab for further testing; this is called an endoscopic biopsy
• help your doctor see inside the body during a surgical procedure, such as repairing a stomach ulcer, or removing gallstones or tumors

Your doctor may order an endoscopy if you’re having symptoms of any of the following conditions:

• inflammatory bowel diseases (IBD), such as ulcerative colitis (UC) and Crohn’s disease
• stomach ulcer
• chronic constipation
• pancreatitis
• gallstones
• unexplained bleeding in the digestive tract
• tumors
• infections
• blockage of the esophagus
• gastroesophageal reflux disease (GERD)
• hiatal hernia
• unusual vaginal bleeding
• blood in your urine
• other digestive tract issues

Your doctor will review your symptoms, perform a physical examination, and possibly order some blood tests prior to an endoscopy. These tests will help your doctor gain a more accurate understanding of the possible cause of your symptoms. These tests may also help them determine if the problems can be treated without endoscopy or surgery.

 

How do I prepare for an endoscopy?

Your doctor will give you complete instructions on how to prepare. Most types of endoscopy require you to stop eating solid foods for up to 12 hours before the procedure. Some types of clear liquids, such as water or juice, might be allowed for up to two hours before the procedure. Your doctor will clarify this with you.

Your doctor may give you laxatives or enemas to use the night before the procedure to clear your system.

Be sure to tell your doctor about any medications you’re taking, including over-the-counter drugs and nutritional supplements. Also alert your doctor about any allergies you might have. You may need to stop taking certain medications, such as anticoagulant or antiplatelet drugs.

You may want to plan for someone else to drive you home after the procedure because you might not feel well from the anesthesia.

 

What are the risks of an endoscopy?

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:

• chest pain
• damage to your organs, including possible perforation
• fever
• persistent pain in the area of the endoscopy
• redness and swelling at the incision site

 

The risks for each type depend on the location of the procedure and your own condition.

Ask your doctors about symptoms to look out for following your endoscopy.

 

The patient should not do following works up to 24 hours after receiving hypnotic drugs:

• Driving
• Taking care of another person (child, elderly)
• Signing any legal form
• consumption of alcohol

The effects of hypnotic drugs usually disappear after 24 hours, but if you still feel drowsy, rest for another 24 hours.
