Endoscopies are performed by highly trained Doctors of Gastroenterology at NWH. The Chief of the NWH Gastroenterology Division is Elie Abemayor, MD.

Endoscopies are non-surgical procedures that use a thin flexible tube with a fiber-optic light and camera to examine the digestive tract. Some of the common endoscopic services performed at NWH include Colonoscopies, Gastroscopy or Upper Endoscopy, Bronchoscopy, Endoscopic Retrograde Cholangiopancreaticography (ERCP), and Endoscopic Ultrasound.

Endoscopic services include:

Colonoscopy is a procedure for viewing the walls of the colon (large intestine). The doctor passes the scope through the rectum into the colon. Colonoscopy is one of the best ways of screening for colon and rectal cancer.
The procedure lasts about one hour; it may be shorter or longer depending on what needs to be done. The recovery period after the procedure is usually about 30 to 60 minutes.

Colonoscopy Procedure—What to Expect and How to Prepare
Sedatives are given to make you drowsy and comfortable. During the procedure you will lie on your side on an examining table. The instrument used to perform a colonoscopy is a flexible tube called a colonoscope, containing a small hollow channel and a light & lens system. The colonoscope is ½ inch in diameter. It is inserted in the rectum and passed through the large intestines. This permits a visual and photographic inspection of the colon.

If the doctor sees something abnormal during the colonoscopy, the doctor can perform minor surgical procedures with the colonoscope such as: biopsy, hemostasis, injection of medication, dilation, removal of polyps, and others.

Gastroscopy or Upper Endoscopy
By passing the scope through the mouth and throat, the doctor can view the esophagus, stomach, and upper part of the small intestines.

By passing the scope through the mouth and throat, the doctor can examine your throat, larynx, trachea and lower airway.

Endoscopic Retrograde Cholangiopancreaticography (ERCP)
This type of upper endoscopy allows the doctor to take pictures of the pancreas and gallbladder.

Endoscopic or Bronchoscopic Ultrasound
This procedure combines an upper endoscopy or bronchoscopy with an ultrasound examination. The endoscopic or bronchoscopic ultrasound is one of the innovations NWH has instituted. The ultrasound allows NWHdoctors to pinpoint a tumor more accurately, resulting in better visualization of a tumor and better quality of the biopsy.
