Sigmoidoscopy
SIG
Description
"Sigmoidoscopy" test examines the rectum and lower part of the colon to screen for colorectal cancer, polyps, or inflammation. A flexible tube with a camera is carefully positioned through the rectum to capture images of the colon lining. It’s often recommended for those over 50 or with a family history of colon issues. This test helps identify early signs of disease, support clinical decisions, and promote preventive care through routine monitoring of lower gastrointestinal health.

Test Group Description
Endoscopic Procedure Group: This group encompasses a range of diagnostic and therapeutic procedures performed using an endoscope, a flexible tube with a camera and light at its tip. These procedures allow healthcare providers to visualize internal organs and tissues, such as the gastrointestinal tract, respiratory system, and urinary tract.
Optimal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Normal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Anal fissures (Small tears in the lining of the anus)
Anal fistula (Abnormal tunnel-like passage between the anal canal and the skin near the anus)
Anorectal abscess (Collection of pus in the anal or rectal area)
Colorectal cancer (Malignant growth or tumor in the colon or rectum)
Colitis (Inflammation of the colon)

Key Reasons For Testing
Colorectal Cancer Screening: Detects precancerous polyps or early cancers in the sigmoid colon and rectum.
Diagnostic Evaluation: Identifies conditions like inflammatory bowel disease, diverticulosis, and colorectal infections.
Symptom Assessment: Investigates rectal bleeding, bowel habit changes, abdominal pain, and unexplained weight loss.
Therapeutic Intervention: Allows for polyp removal, biopsies, and treatment of bleeding lesions or hemorrhoids.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
