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.
