Rectal bleeding is a frequent symptom in proctology. In most cases frequent causes, such as anal fissures and hemorrhoidal disease can be diagnosed and treated using a structured patient history and basic proctological diagnostic assessment; however, it is not uncommon for proctitis to be the reason for rectal bleeding, which necessitates interdisciplinary diagnostics and treatment. In addition to proctitis associated with chronic inflammatory bowel disease, prolapse-induced, radiogenic, ischemic, infectious types and proctitis associated with sexually transmitted diseases represent important differential diagnoses. Moreover, rectal cancer has to be excluded as the cause of rectal bleeding. Finally, with appropriate diligence most causes of rectal bleeding can be securely identified and effectively managed; however, special circumstances can necessitate interdisciplinary diagnostics and management, including conservative, topical, interventional and surgical treatment options.
