What Is an Endoscopy? | Stomach Problems


Endoscopy is where we examine the upper digestive
tract with a flexible tube that’s passed from the mouth, into the esophagus, the stomach,
and the small bowel. This flexible tube basically has a light source,
and a bunch of different channels through which we can pass instruments to take biopsies
or to treat lesions. This is a great tool to evaluate the esophagus,
the stomach, and the small bowel. We can take biopsies. We can see where ulcers are. We can biopsy any lesions to see if there
is any cancer or tumors. So this is a great tool that gastroenterologist
use to examine the upper digestive tract. It was invented in the 1930’s or 40s’, and
perfected in the 1960’s, and now it’s basically a fiber optic tube that has a light source
that allows us to see around corners, and we can control the visualization of the gastrointestinal
wall.
