An endoscopy is the process of examining the internal parts of human body using an instrument known as endoscope. An endoscope is a medical device having a flexible tube with light and a camera. Using the endoscopy, the images of the interior of the body can be seen on a screen. Endoscopy was first carried out in 1805 which included a large tube and a candle. But this was cumbersome and large. Later when after discovery of fiber optics, endoscopy became easy and effective.
An endoscope mainly consists of:
A rigid or flexible tube.
A light that helps the doctor to see the interior of the body.
A lens system that is used to transmit the image on the screen from the fiberscope.
Another channel to allow the entry of medical manipulators.
A doctor can recommend an endoscopy for:
Confirmation of diagnosis, by performing biopsy to check for anemia, inflammation, bleeding, cancers of digestive systems.
Investigation of symptoms like vomiting, nausea, gastrointestinal bleeding, abdominal pain.
Providing treatments like widening of narrow esophagus, cauterization of bleeding vessels, removing of foreign object from the body.
Endoscopy is performed when a person is awake and is not painful. A local anesthetic or sedative may be given to relax. The endoscope is properly inserted in the body where the test has to be carried out. It can take about 15-20 minutes depending on which body part is to be examined.
There are different types of endoscopies done today.
Some of them are listed below:
Laparoscopy: a small incision done to examine abdominal cavity.
Amnioscopy: examination of fetus and amniotic cavity.
Cystoscopy: examination of urinary bladder.
Arthroscopy: examination of the joints.
Fetoscopy: examination of the fetus.
Colonoscopy: examination of the colon.
Thoracoscopy: examination of the lungs or organs in chest cavity.
Proctoscopy: examination of the end of colon and the rectum.
Endoscopy hardly causes any major complications, few occurring are:
An allergy due to anesthetic.
Bleeding more than expected.
Infection, where the endoscope was inserted.
Piercing or tearing of the organ.
Infection caused due endoscopy can show following symptoms:
Fluid or Pus Discharge
