A nonsurgical method used for examining the digestive tract of the human body is endoscopy. In this procedure, a flexible tube having a camera and light is used to view pictures of the digestive tract on the TV monitor.
When upper endoscopy is conducted via mouth an endoscope is inserted into the esophagus to view the small intestine’s upper part, stomach, and esophagus.
For examining the large intestine endoscope is inserted via the rectum.
Endoscopy can be combined with other procedures too like ultrasound. With endoscope and ultrasound probe are attached for getting better images of the stomach or esophagus. Organs that are hard to reach like the pancreas images can also be created by using endoscopic ultrasound.
Endoscopes also allow doctors to use advanced technology known as narrow-band imaging. It makes use of special light facilitating in finding precancerous conditions.
