What is an Endoscopy?

Endoscopy is a procedure in which a long, thin tube is inserted into the body to thoroughly examine an organ or tissue. It can also be used for imaging and minor surgery. Endoscopes are instruments that can be inserted into body openings such as the mouth or the anus. It enables your doctor to examine an organ without making a large incision; the doctor can view the endoscope on a screen in the operating room.

Who performs an Endoscopy?

Specialists of different diseases can perform endoscopy according to the body part that needs to be examined. For example, a Gastroenterologist will perform an endoscopy if your GI tract needs an examination.

Types of Endoscopy

Endoscopy can be used to examine a wide range of body parts, including:

• Esophagogastroduodenoscopy: (upper GI endoscopy) for esophagus, stomach, and duodenum
• Enteroscopy: for small  intestine
• Colonoscopy: examines  large intestine/colon
• Retinoscopy: for bile duct, rectum, and anus.
• Rhinoscopy: for lower  respiratory tract
• Bronchoscopy: for the nose
• Otoscopy: for the inner ear.
• Cystoscopy: examines the urinary tract.
• Gyroscope: of the  female reproductive tract
• Laparoscopy: for the  abdominal or pelvic cavity
• Arthroscopy: examines  the interior of a joint
• Thoracoscopy: for the  organs of the chest

Preparations before an Endoscopy

Your doctor will provide you with detailed information on how to prepare for your procedure:

• Dietary Restrictions: Your doctor might ask you to stop eating high-fiber foods like whole grains, raw vegetables, nuts, and seeds.
• Fasting: The majority of endoscopies need you to fast for up to 12 hours before the operation. Some clear beverages, such as water or juice, may be consumed up to two hours before the treatment only if your doctor advises.
• Laxatives: To empty your system the night before the treatment, your doctor may prescribe laxatives or enemas. This is a common occurrence in operations involving the GI tract and the anus.
• Physical Exam: Your doctor will perform a physical examination and review your whole medical history before the endoscopy, including any previous procedures.
