How is Endoscopy Performed?

During an endoscopy procedure, the patient is typically given sedation to help them relax and minimize discomfort. The endoscope is then inserted into the body through a natural opening, such as:

  • Upper endoscopy (esophagogastroduodenoscopy or EGD): Used to examine the esophagus, stomach, and duodenum.

  • Colonoscopy: Used to examine the large intestine (colon) and rectum.

  • Flexible sigmoidoscopy: Similar to a colonoscopy but focuses on the lower part of the colon and rectum.

  • Endoscopic ultrasound (EUS): Combines endoscopy with ultrasound imaging to visualize structures deep within the body, such as the digestive tract and surrounding tissues.

  • Capsule endoscopy: Involves swallowing a pill-sized camera that takes pictures as it travels through the digestive tract.

  • Laparoscopy: Involves inserting a thin, lighted tube through a small incision in the abdomen to examine the abdominal organs or perform surgical procedures.

The camera at the tip of the endoscope transmits images to a monitor, allowing the healthcare provider to examine the inside of the body in real-time.
