A sigmoidoscopy procedure is primarily used for:

The sigmoidoscopy procedure is primarily utilized for examining the sigmoid colon, which is the part of the large intestine located just above the rectum. This procedure allows healthcare professionals to visually inspect the inner lining of the sigmoid colon and the rectum for abnormalities such as inflammation, polyps, or signs of disease. By introducing a flexible tube equipped with a light and camera into the rectal area, clinicians can obtain valuable information which can assist in diagnosing various gastrointestinal conditions.

The focus on this specific area is essential because many diseases can originate there or affect it, and early detection can lead to more effective treatment options. This specialization makes sigmoidoscopy an important tool in gastrointestinal diagnostics and screening, particularly for conditions like colorectal cancer.
