Sigmoidoscopy is a minimally invasive endoscopic procedure used to examine the rectum and sigmoid colon for abnormalities affecting the lower gastrointestinal tract. It plays an important role in diagnosing conditions such as rectal bleeding, chronic diarrhea, inflammatory bowel disease, colorectal polyps, diverticular disease, and early colorectal cancer. The procedure provides direct visualization of the intestinal lining and enables targeted tissue biopsy when required.
Diagnostic sigmoidoscopy facilitates early identification of colorectal diseases before symptoms become severe. It allows gastroenterologists to detect inflammation, ulcers, polyps, strictures, infections, and malignant lesions with high precision. Early diagnosis supports timely medical or surgical intervention, improves treatment outcomes, and reduces the risk of progression to advanced colorectal disease.
Beyond diagnosis, sigmoidoscopy offers several minimally invasive therapeutic procedures, including sclerotherapy, banding, Argon Plasma Coagulation (APC), polypectomy, and Endoscopic Mucosal Resection (EMR). These interventions effectively control lower gastrointestinal bleeding, remove precancerous polyps and early cancers, treat vascular lesions, and reduce the need for conventional surgery, resulting in faster recovery and improved patient outcomes.
