Once you are slightly sedated, he will insert a slim, plastic tube with light and lens at the end to detect abnormalities. This tube is also known as endoscope. With this method, the doctor can find out injury to the esophagus. At times, a biopsy can also be done where he can use forceps or small tweezers to go through the endoscope so that he can take a piece of little tissue and study it under the microscope for abnormalities and infection.
pH monitoring examination
