Overview

Colonoscopy is considered as a gold standard for evaluating intestine, diagnostic and therapeutic approaches. Tissue biopsy and polypectomy could be done during colonoscopy. Findings on a colonoscopy and flexible sigmoidoscopy suggestive of familial adenomatous polyposis include visual detection of multiple colon polyps. Colonoscopy has 0.02% mortality and 0.2% morbidity 0.2%. Colonoscopy has side effects including pain, risk of perforation and bleeding.

  • Capsule endoscopy may be helpful in the diagnosis of familial adenomatous polyposis.[9]
    • Findings on a capsule endoscopy suggestive of colon polyps include visual detection of multiple polyps.
    • It assesses the location, size, and number of small-bowel polyps.
    • It is recommended for the surveillance of jejunal-ileal polyps in selected patients.
    • Relative contraindication for capsule endoscopy is abdominal surgery.
  • Forward-viewing and side-viewing endoscopy may be helpful in the diagnosis of familial adenomatous polyposis.
    • Forward-viewing and side-viewing endoscopy are used for surveillance of periampullary and duodenal polyposis.
