An upper endoscopy is a minimally invasive diagnostic medical procedure that assesses the upper digestive system and the interior surfaces of the esophagus and stomach by inserting a tube into the body. The instrument may have a rigid or flexible tube with a camera that provides images for visual inspection. It can also take biopsies and retrieve foreign objects. Endoscopy is the vehicle for minimally invasive surgery.
A capsule endoscopy differs from an upper endoscopy in that the camera is inside a pill-sized capsule that you swallow. The camera then takes pictures of your small intestine, which is harder to reach and assess with an upper endoscopy, and transmits to a belt you wear equipped with a recorder so your gastroenterologist can review the images and assess your individual condition.
Endoscopic procedures help diagnose a number of digestive disorders and conditions:
- Crohn’s disease
- Diverticulosis and diverticulitis
- Gastroesophageal reflux disease (GERD)
- Hiatal hernia
- Lactose intolerance
- Ulcerative colitis
- Ulcers of the stomach and duodenum
