Anal fistula is the sequelae of perianal abscess, which has a causal relationship with perianal abscess, a chronic infectious disease, which is characterized by frequent and repeated pain at the external opening of the anal fistula, breakage of a small amount of purulent, bloody, mucus secretions and itching caused by secretions irritating the skin, while hemorrhoids are normal structures with important physiological functions that everyone has —– The anal cushion becomes pathologically enlarged and The main symptoms are bleeding and prolapse during defecation, which are almost identical to hemorrhoids in terms of etiology, symptoms, signs and site of onset, so it is easy to distinguish, and the initial diagnosis can be made basically based on the patient’s complaints alone, and then combined with routine anorectal examinations (including visual examination, finger examination + anoscopy) can completely distinguish and clearly diagnose, and the treatment methods adopted for them are completely different. The treatment methods for them are also completely different. Therefore, in the opinion of anorectal specialists, anal fistula and hemorrhoids are two different diseases that are basically unrelated. Although anal fistula is one of the common diseases in anorectology, like perianal abscess, anal fistula is not as well known as hemorrhoids, so there are often patients with anal fistula who claim to have hemorrhoids (they think they have hemorrhoids because they are uncomfortable in the anus), when in fact they have anal fistula and not hemorrhoids. The most important thing is to make sure that you have a good idea of what you are doing.
