Flexible sigmoidoscopy is a method for evaluating the rectum and lower part of the large bowel (the colon) for the presence of growths or other conditions, especially cancer. The American Cancer Society recommends that people age 50 and older, of average risk, should have a flexible sigmoidoscopy exam to screen for colon cancer every five years. The flexible sigmoidoscope is a tubular instrument that allows physicians to visualize the lining of the colon and to take samples (biopsy), if necessary.

Physicians who serve Rutgers Health Gastroenterology are skilled in the flexible sigmoidoscopy procedure. Our doctors are faculty members of Rutgers New Jersey Medical School, a part of Rutgers University, one of the top research institutions in America. Our physicians are also active in research and in teaching about all aspects of gastroenterology and hepatology. Each brings life-changing knowledge from the classroom to the exam room.

How Does Flexible Sigmoidoscopy Work?

Patients assume a comfortable position on their left side, which allows a physician to insert the sigmoidoscope into the rectum. Small amounts of air blow into the rectum so the bowel lining can be seen cleanly. If the physician detects abnormalities, such as polyps, he or she may perform a biopsy using a special pair of forceps (tweezers), with samples going to the pathology laboratory for evaluation. Biopsies are usually painless but may cause a small amount of blood to show up in the stool over the next few days. People who have had difficulty with abnormal bleeding in the past or are on blood thinning medications should let their physician know before the test.

A flexible sigmoidoscopy typically takes 15 to 20 minutes. Patients may experience some abdominal cramping or the sensation of needing a bowel movement during the procedure; this is entirely normal. If there is a lot of discomfort during the procedure, inform the physician. Once the procedure is complete, the examining physician will discuss results with the patient and send a report to the referring physician.
