Which of the following is a type of intussusception?

  1. Ileocolic

  2. Ileostomy

  3. Jejunoileal

  4. Colovesical

The correct answer is: Ileocolic

Intussusception refers to a condition in which a segment of the intestine telescopes into an adjacent segment, leading to obstruction and potentially compromising blood supply. The correct choice, ileocolic, specifically describes one of the most common types of intussusception seen, particularly in children. In this case, ileocolic intussusception involves the ileum (the last portion of the small intestine) sliding into the cecum or the beginning of the large intestine. This type is significant clinically because it can lead to major complications, such as bowel ischemia if not addressed promptly. While the other choices like ileostomy (a surgical procedure), jejunoileal (which refers to the connection between the jejunum and ileum but does not indicate intussusception), and colovesical (a fistula between the colon and bladder, not classified as intussusception) are relevant terms in gastrointestinal pathology, they do not describe a specific type of intussusception. Thus, the ileocolic type is correctly identified as a defined and actionable subtype of this serious condition.
