True about Intussusceptions in children
**Core Concept**
Intussusception is a medical emergency in children where a part of the intestine invaginates into another, leading to bowel obstruction and potentially life-threatening complications. The condition is characterized by abdominal pain, vomiting, and bloody stools.
**Why the Correct Answer is Right**
The correct answer is related to the management of intussusception. The Henoch-Schönlein purpura (HSP) is a common cause of intussusceptions in children. The condition often involves the ileocolic junction, where the ileum invaginates into the colon. The diagnosis is typically made with ultrasound, and the treatment involves air enema reduction under fluoroscopic guidance. If unsuccessful, surgical intervention may be required.
**Why Each Wrong Option is Incorrect**
**Option A:** Intussusception is most commonly caused by lead points such as Meckel's diverticulum. While this can be a cause of intussusception, it is not the most common cause in children.
**Option B:** The most common age group affected by intussusception is infants younger than 6 months. However, the correct answer is related to a specific cause of intussusception.
**Option C:** Intussusception is a rare condition in adults. While it can occur in adults, the correct answer is related to a specific cause of intussusception in children.
**Option D:** The treatment of intussusception involves surgical intervention. While surgical intervention may be required, the correct answer is related to a specific cause of intussusception.
**Clinical Pearl / High-Yield Fact**
The classic triad of intussusception in children includes abdominal pain, vomiting, and bloody stools. The presence of this triad should raise suspicion for intussusception, and prompt evaluation with ultrasound is essential.
**Correct Answer:** D.
