What is a Flexible Sigmoidoscopy?
A flexible sigmoidoscopy is a critical diagnostic tool to evaluate the health of your large intestine or colon. An ultra-thin, flexible tube called a sigmoidoscope is inserted in the rectum and guided up through the intestine.
The tube contains a tiny camera at the end which provides the doctor with a view of your sigmoid colon, which is the last two feet of the large intestine. The sigmoidoscope also allows the doctor to take samples of tissue for later biopsy. Tissue biopsy is the definitive way to determine whether there are precancerous or cancerous changes in your tissue cells.
The sigmoidoscopy procedure is often combined with a colonoscopy because the sigmoidoscope doesn’t show the entire colon, only the lower portion. Sigmoidoscopy may be recommended over colonoscopy because it often doesn’t require anesthesia and is a faster procedure than colonoscopy.
A flexible sigmoidoscopy can be used to determine the cause of intestinal problems like abdominal pain and bowel issues like diarrhea and constipation. It is also used to look for abnormal growths or polyps. It is also a vital tool to screen for colon and rectal cancer.
Flexible sigmoidoscopy may be recommended if you are over 50 years old to help detect colon and rectal cancer in the early stages when it is the most treatable. Colorectal cancer is the third leading cause of cancer-related deaths in the United States, according to the American Cancer Society. Each year, about 150,000 new cases are diagnosed in this country, and 50,000 people will die of the disease.
The flexible sigmoidoscopy procedure is a safe, effective way to determine the health of your sigmoid colon. It is a vital tool in maintaining your good health. If you are having abdominal issues, or you are at least 50 years old, flexible sigmoidoscopy can help you. Your gastroenterologist can tell you more about flexible sigmoidoscopy and other procedures to help you feel better.
