The accompanying symptoms were prolonged diarrhea (31.2%), anemia (31.2%), abdominal pain (27.6%). Lesions on colonoscopy were found in 93.1% of patients in which 61.2% was polyp. Common causes of lower gastrointestinal bleeding were are polyps (60.6%), infectious diarrhea (14.6%), inflammatory bowel disease (9.4%), Meckel’s diverticulum (4.7%).
