Endoscopic Procedure - Indications, Types, How It Is Done, Risks, And Complications

An endoscopy is a procedure to visualize internal organs using an endoscope, which is a long, thin, flexible tube that has a light and camera at one end.
Images of internal organs are shown on a television screen.
Endoscopy is indicated for investigation of various clinical presentations.
Some of them include, dysphagia, or difficulty in swallowing, Unexplained abdominal pain and heartburn, vomiting of blood, bleeding per rectum, unintentional weight loss with other gastrointestinal symptoms, unexplained respiratory symptoms etc.
In addition, endoscopy may be used to take biopsies, and for the treatment of certain disease conditions.
Endoscopes can be put through the oral cavity into the gastrointestinal tract, to the larynx and trachea, or through the anus.
In addition, endoscope can also be inserted through a small cut made in the skin, when laparoscopic surgery is being done.
If the esophagus, stomach, or proximal part of the small intestine is being looked at, it is known as upper GI endoscopy.
If the colon is being looked at, it is known as lower GI endoscopy or colonoscopy.
Other types of endoscopies include, Bronchoscopy, to visualize the Airways, Hysteroscopy, to visualize the uterus, Cystoscopy, to visualize the bladder, Arthroscopy, to visualize and repair joints, and endoscopic ultrasound, to yield images of internal organs such as pancreas and take biopsies.
