Overview

Intussusception may be classified into several subtypes based on location and etiology. According to location of intussusception it is classified into ileocolic, ileo-ileo-colic, jejuno-jejunal, jejuno-ileal, and colo-colic. According to etiology of intussusception it is classified into idiopathic or lead point (pathologic) types.

Classification

Intussusception can be classified according to various parameters:-
- Classification of intussusception based on its location:-
  - Ileocolic intussusception^[1]
    - 90% cases.
    - It involves the ileocecal junction.
  - Ileo-ileo-colic
  - Jejuno-jejunal
  - Jejuno-ileal
  - Colo-colic

Types

Ileocolic

Ileo-Ileo-Colic

Jejuno-jejunal

Jejuno-Ileal

Colo-Colic

Classification based on etiology
- Intussusception can be classified into 2 types based on etiology:
  - Idiopathic:
    - In the idiopathic type there is no clear trigger point.
    - Most commonly seen in children.
  - Lead point:
    - In the lead point type there is a clear pathologic trigger.
    - Most commonly seen in adults.

Children

Idiopathic- no lead point

Pathologic- Lead point
