Blood in the stool is a common symptom of many pediatric diseases. It can be caused by systemic diseases, such as various blood diseases, or by upper gastrointestinal diseases, such as various inflammatory diseases; it can also be caused by anorectal diseases.
The following are some of the common anorectal diseases caused by bleeding: pediatric rectal polyps: blood in the stool is the most common symptom of rectal polyps, mostly caused by bleeding when stool abrasion and polyp tip fracture. The amount of blood is variable, bright red, does not mix with stool, and is painless.
Pediatric intussusception: Pediatric intussusception is one of the acute intestinal obstruction, mostly seen in infancy. The main symptoms are blood in the stool, vomiting, abdominal pain and abdominal mass. Blood in stool is often found during rectal examination and is an important basis for definitive diagnosis.
Anal fissure: Anal fissure blood in stool is usually caused by tearing the anal edge with forceful defecation when the stool is dry and hard, with severe pain.
Hemorrhoids: Bleeding internal hemorrhoids, mostly after a bowel movement, no pain, blood mostly attached to the stool, bright red color. Although the incidence of pediatric hemorrhoids is low and blood in the stool is rare, they are the most common disease of the anus, so they should not be ignored in clinical practice.
Infant hemorrhoids: I’m afraid it’s a little known fact that infants can also have hemorrhoids. The symptoms of infant hemorrhoids are redness and swelling on both sides of the buttocks, which sometimes turn into perianal ulcers. For those who don’t know, it is often mistaken for diaper rash. The bleeding is a small, fresh amount of blood on paper wipes after a bowel movement.
