It is the procedure used to help diagnose and treat a series of gastrointestinal and respiratory problems.
It uses an endoscope, which is a long, very flexible tube that carries a very small camera attached on its end. In addition, within the tube there is a canal that allows the usage of instruments such as snares and biopsy items.
Such procedure is normally recommended when X-ray, urine and blood test could not provide an answer for the problem. It can tell the presence of foreign object in the stomach area as well as any suspicious or abnormal areas within stomach, respiratory, colon and intestine tract. The procedure is not painful once general anesthesia is required.
