Differential Diagnosis for Rectal Bleeding in a Child
Single Most Likely Diagnosis
- Constipation with Anal Fissure: The presence of blood in the stool after wiping, combined with a history of hard bowel movements, suggests that the child may have an anal fissure caused by constipation. The use of a stool softener by the mother also supports this diagnosis.
Other Likely Diagnoses
- Gastroenteritis: Infections such as gastroenteritis can cause rectal bleeding, especially if the child has a history of diarrhea or abdominal pain.
- Hemorrhoids: Although less common in children, hemorrhoids can cause rectal bleeding, especially if the child has a history of constipation or straining during bowel movements.
- Food Allergy or Intolerance: Certain food allergies or intolerances, such as a milk protein allergy, can cause rectal bleeding in children.
Do Not Miss Diagnoses
- Intussusception: A serious condition where a part of the intestine telescopes into another part, causing bowel obstruction and potentially life-threatening complications. Although less common, it is a critical diagnosis to consider in a child with rectal bleeding.
- Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause rectal bleeding, abdominal pain, and changes in bowel habits. Early diagnosis and treatment are crucial to prevent long-term complications.
- Meckel's Diverticulum: A congenital anomaly of the small intestine that can cause rectal bleeding due to the presence of gastric mucosa.
Rare Diagnoses
- Juvenile Polyps: Benign growths in the colon that can cause rectal bleeding, although they are relatively rare in children.
- Vascular Malformations: Abnormalities of the blood vessels in the gastrointestinal tract that can cause rectal bleeding.
- Infectious Colitis: Certain infections, such as Salmonella or Shigella, can cause rectal bleeding, although they are less common in children.
