Recurrent intussusception occurs in about:
**Core Concept**
Recurrent intussusception refers to the repeated invagination of a part of the intestine into another, leading to bowel obstruction and potentially life-threatening complications. This condition requires prompt diagnosis and treatment to prevent long-term consequences.
**Why the Correct Answer is Right**
The exact cause of recurrent intussusception is often unclear, but it is thought to be related to the presence of a lead point, such as a Meckel's diverticulum, intestinal polyp, or other anomaly. The invagination of the intestine can lead to bowel obstruction, ischemia, and even perforation if left untreated. In some cases, recurrent intussusception may be associated with underlying conditions such as Henoch-Schönlein purpura or cystic fibrosis.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not provide a specific percentage or frequency of recurrent intussusception.
**Option B:** This option is incorrect as it is too low and does not accurately reflect the frequency of recurrent intussusception.
**Option C:** This option is incorrect as it is too high and may not accurately reflect the true frequency of recurrent intussusception.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that recurrent intussusception often requires surgical intervention, and prompt diagnosis is crucial to prevent long-term complications. A high index of suspicion and a thorough physical examination, including a digital rectal exam, can help identify this condition early.
**Correct Answer: C. 5-10%**
