An endoscopy is a simple procedure that allows a doctor to look inside human bodies using an instrument called an endoscope. A cutting tool can be attached to the end of the endoscope, and the apparatus can then be used to perform minor procedures such as tissue biopsies, banding of oesophageal varices or removal of polyps.
Also, in cystoscopy, which is the examination of the urinary bladder with an endoscope, narrow-band imaging is useful in differentiating between benign and malignant cells. [6] Alternative methods to improve visualization of the mucosa in endoscopy include chromoendoscopy, confocal microscopy and optical coherence tomography. [citation needed]
Upper endoscopy within 24 hours is the recommended treatment. [ 15 ] [ 23 ] The benefits versus risks of placing a nasogastric tube in those with upper gastrointestinal bleeding are not well known. [ 15 ]
An endoscope is an inspection instrument composed of image sensor, optical lens, light source and mechanical device, which is used to look deep into the body by way ...
Endoscopy, the examination of the stomach with a fibre-optic scope, is not routinely needed if the case is typical and responds to treatment. [42] It is recommended when people either do not respond well to treatment or have alarm symptoms, including dysphagia , anemia , blood in the stool (detected chemically), wheezing , weight loss, or voice ...
The most common is endoscopy. This procedure is performed as an outpatient and utilizes a small flexible camera. The procedure does require intravenous sedation and takes about 30–45 minutes; the endoscope is inserted via the mouth and can visualize the entire swallowing tube, stomach and duodenum.
Confocal endoscopy, or confocal laser endomicroscopy (CLE), is a modern imaging technique that allows the examination of real-time microscopic and histological features inside the body. In the word "endomicroscopy", endo- means "within" and -skopein means "to view or observe".
The endoscope is then passed over the tongue and into the oropharynx. This is the most uncomfortable stage for the patient. Quick and gentle manipulation under vision guides the endoscope into the esophagus. The endoscope is gradually advanced down the esophagus making note of any pathology.
