A 3-year-old child presents to the emergency department with intermittent abdominal pain, vomiting, and “currant jelly” stools. The clinical team suspects intussusception and plans to confirm the diagnosis through imaging studies. They are considering the common types of intussusception that occur in this age group.
What is the most common type of intussusception?
A. Ileo-colic
B. Ileo-ileal
C. Colo-colic
D. No one is common
E. All are common
The Correct Answer is: A. Ileo-colic
Explanation:
– Ileo-colic (A): The most common type of intussusception, particularly in children, is ileo-colic intussusception. This type occurs when the ileum (the last part of the small intestine) telescopes into the colon (large intestine), leading to obstruction and potential ischemia. It is the most frequently observed type in pediatric cases.
Explanation of Incorrect Options:
– Ileo-ileal (B): Ileo-ileal intussusception, where one part of the ileum telescopes into another segment of the ileum, is less common than ileo-colic intussusception.
– Colo-colic (C): Colo-colic intussusception, where one part of the colon telescopes into another part of the colon, is rarer and more commonly seen in adults, particularly in cases with underlying pathology.
– No One is Common (D): This option is incorrect as ileo-colic intussusception is indeed common in pediatric populations.
– All Are Common (E): While various types of intussusception exist, not all are common. Ileo-colic intussusception is the most prevalent type, making this option incorrect.
In summary, ileo-colic intussusception is the most common type, particularly in children, making option A the correct answer.
