Although internal haemorrhoids and anal fissures are both bright red blood in the stool, the accompanying symptoms and clinical indications are somewhat different. While internal haemorrhoids may be painless, most anal fissures are painful and persistent after a bowel movement. Through anoscopy, internal haemorrhoids bleeding in the stool can be seen as bleeding from a ruptured mucosa of the haemorrhoidal nucleus, whereas anal fissures bleeding in the stool are located as localised fissures in the anal canal mucosa.
