Answer

Benign anorectal disease (eg, hemorrhoids, anal fissures, anorectal fistulas) can cause intermittent rectal bleeding. Massive rectal bleeding due to benign anorectal disease has also been reported. A review of the Department of Veterans Affairs (VA) database revealed that 11% of patients with LGIB had hemorrhage from anorectal disease. [13]

Postpolypectomy hemorrhage is reported to occur in 0.1%-3% of patients up to 1 month following colonoscopic polyp resection.

Various small intestinal conditions, such as Crohn disease, Peutz-Jeghers syndrome, hemangiomas, and small intestinal adenocarcinomas, may cause small intestinal bleeding, but these hemorrhages are usually occult in nature.
