What is Endoscopy
Endoscopy is a procedure which is used by doctors to visually examine the internal body organs by
using an instrument called an endoscope. Endoscopy procedures are quick and relatively safe
procedures and is a common procedure used by doctors to perform minimally invasive surgeries.
The endoscope is an instrument with a tiny camera on the end of a long, flexible tube. It is inserted
into the body to observe internal organs or tissue in detail for diagnosis or treatment. Endoscopes
can be inserted into the openings of the body such as the mouth or anus. They can also be inserted
through small incisions, for instance, in the knee or abdomen. Surgery completed through a small
incision and assisted with special instruments.
Indications – When is Endoscopy preformed?
Endoscopy is done for investigating/treating many systems within the human body. Endoscopy is
often combined with other procedures. For instance, an imaging tool may be attached to the
endoscope to create focused images. One such example is an endoscopic ultrasound. These
techniques help the doctor to create images of hard-to-reach organs to provide clearer images.
Many organs in the human system may need endoscopy for investigation. These include:
       The Gastrointestinal tract which includes esophagus, stomach, duodenum, small intestine,
        large intestine/colon, bile duct, rectum and anus.
       Respiratory tract organs: Nose, lower respiratory tract
       Ear
       Urinary tract
       Female reproductive tract which includes the cervix, uterus and fallopian tubes.
       Apart from these the abdominal cavity, bone joints such as knee and organs of the chest
        may also need endoscopic intervention.
Endoscopic surgeries
With advancement in technology, Endoscopy is being used widely in recent years to perform non-
invasive surgeries. The common surgeries include removal of the gallbladder, sealing and tying the
fallopian tubes, removal of small tumours etc.
The advanced endoscope (commonly referred as a Laparoscope) requires only a small incision. Apart
from smaller cuts, this technique involves less blood loss, less pain and faster recovery.
