An endoscope is a testing instrument that integrates conventional optics, ergonomics, precision instruments, modern electronics, mathematics, and software. One is equipped with an image sensor, optical lens, light source illumination, mechanical equipment, etc. so that it can enter the body from the mouth to the stomach or through another natural opening. Endoscopy is very useful for doctors because it allows you to see lesions that are not visible on X-rays. For example, with the help of an endoscope, doctors can look for ulcers or tumors in the stomach and plan the best treatment accordingly.
Discover the causes of symptoms
When you see a doctor with the symptoms you may have, you may be able to find the cause with an endoscope. For instance:
- Laryngoscopy to examine the vocal cords of people with slow hoarseness.
- Gastroscopy in people with dysphagia.
- Colonoscopy in people with anemia of unknown cause (low red blood cell count).
- Colonoscopy in people with blood in the stool.
Look at problems endoscopes use for:
- To remove a tissue sample
- To take a closer look
- To capture better images
- Endoscopic Ultrasound (EUS)
- Endoscopic Retrograde Cholangiopancreatography (ERCP)
- Destruction or removal of cancer cell
- Surgery to remove the cancerous tumor
