Endoscopy: Introduction, Risk, Uses & Type

Endoscopy is the insertion of a long, thin tube directly into the body to observe an internal organ or tissue in detail. It can also be used to carry out other tasks including imaging and minor surgery.

A surgeon inserts an endoscope through a small cut, or an opening in the body such as the mouth. An endoscope is a flexible tube with an attached camera that allows the doctor to observe and can use forceps (tongs) and scissors on the endoscope to operate or remove tissue for biopsy.

There are the different type of endoscope. The length and flexibility of endoscope is totally depend on body parts.

When do we need an Endoscope?

An endoscopy to visually examine an organ. An endoscope’s lighted camera allows the doctor to view potential problems without a large incision.

  • Surgery through small incision in the skin, called Laparoscopy Surgery.
  • laser therapy using powerful beam of light to destroy cancer cell.
  • Microwave ablation, using heat to destroy cancerous tissue.
  • Surgery using an endoscope inserted into gastrointestinal tract, called endoscopic mucosal resection or endoscopic submucosal dissection.
  • Photodynamic therapy destroying the tumor with a laser after injecting it with a light-sensitive substance.

Part of an Endoscopes

An endoscope consists of the following components:Image result for endoscope parts

  • Tube: Its depend on body parts either rigid or flexible.
  • Light: The light source is normally outside of the body and directs light internally via an optical fibre system.
  • Lens system: Its designed to transmit the image from the internal end of the endoscope to the viewer. In rigid endoscopes, this is achieved by relay lenses; for flexible scopes, optic fibers are used.
  • Eyepiece:  Endoscopes might be replaced by a display screen.
  • Additional channel: This allows for medical instruments or manipulators to be passed through the endoscope into the body.

Risk

Endoscopy has a much lower risk of bleeding and infection than open surgery. Still, endoscopy is a medical procedure and other rare complications such as:

  • Chest pain
  • Damage to organs, including possible perforation
  • Fever
  • Persistent pain in the area of endoscopy
  • Redness and swelling at the incision site

If any of the following symptoms occur following an endoscopy indicates something went wrong;

  • Dark colored stool
  • Shortness of breath
  • Severe and persistent abdominal pain
  • Chest pain
  • Vomiting blood
