Sigmoidoscopy in New Jersey

The Digestive Health & Nutrition Center has two convenient locations in Lawrenceville and Princeton, New Jersey where you can receive the exceptional care you deserve. Angela Merlo, MD is an experienced Gastroenterologist and highly skilled in performing flexible Sigmoidoscopy in both adults and children.

What is Sigmoidoscopy?

Sigmoidoscopy is a specialized test for examining the lining of the rectum and lower one-third portion of colon. Sigmoidoscopy is similar in concept to colonoscopy and utilizes similar technology but does not permit examination of the higher two-thirds of colon. The sigmoidoscope is a flexible tube with a video camera that transmits images to a computer monitor. The sigmoidoscope is much shorter than a colonoscope. Other instruments can be inserted through the sigmoidoscope to obtain biopsies, resect tumors or polyps or control bleeding. Sedation is not usually administrated during sigmoidoscopy.

When is Sigmoidoscopy Recommended?

The main reasons for sigmoidoscopy are to follow the healing of ulcers, treated polyps or tumors or assess other disorders located within reach of the sigmoidoscope. Sigmoidoscopy is also used to diagnose the cause of:

  • Bleeding
  • Diarrhea

The limitation of the examination is the inability to examine the entire colon. Dr. Merlo recommends a colonoscopy whenever a more complete examination is necessary to properly diagnose and treat your condition.

Is Preparation Necessary?

Yes! Usually two enemas within one to two hours of your procedure are needed but Dr. Merlo will provide detailed instructions for your particular situation and what to do about your medications.  No sedation is administered during sigmoidoscopy so you may drive yourself and resume all normal activities immediately following the procedure.

If you have symptoms suggesting a problem in the rectum or lower colon or are in otherwise in need of sigmoidoscopy contact the Digestive Health & Nutrition Center for an appointment.
