What Is Endoscopy? What Is An Endoscope?
An endoscopy involves examining the inside of a person's body using an endoscope. An endoscope is a medical device consisting of a long, thin, flexible (or rigid) tube which has a light and a video camera. Images of the inside of the patient's body can be seen on a screen. The whole endoscopy is recorded so that doctors can check it again. Endoscopy is a minimally invasive diagnostic medical procedure. It is used to examine the interior surfaces of an organ or tissue.
The endoscope can also be used for enabling biopsies and retrieving foreign objects.
When is an endoscopy used?
To confirm a diagnosis
An endoscopy is often used to confirm a diagnosis when other devices, such as an MRI, X-ray, or CT scan are considered inappropriate.
An endoscopy is often carried out to find out the degree of problems a known condition may have caused. The endoscopy, in these cases, may significantly contribute towards the doctor's decision on the best treatment for the patient.
The following conditions and illnesses are most commonly investigated or diagnosed with an endoscopy:
- Breathing disorders
- Chronic diarrhea
- Incontinence
- Internal bleeding
- Irritable bowel syndrome
- Stomach ulcers
- Urinary tract infections
Biopsies
Endoscopies are commonly used for the diagnosis of cancer. They are used for biopsies - taking samples of tissue to find out whether it is cancerous. Thanks to an endoscope, biopsies of the intestines or lungs can be done without the need for major surgery. This study explains that colonoscopy is the most effective screening option for colorectal cancer.
Surgery
Some surgical procedures can be carried out with a modified endoscope, such as the removal of the gallbladder, tying and sealing the fallopian tubes, and taking out small tumors and foreign objects from the lungs or digestive system. A study found that the removal through endoscopy of tumors that affect only the superficial layers of the esophagus can avoid complete extirpation of this part of the digestive tract.
