Overview

Irritable bowel syndrome (IBS) may be classified according to Rome IV criteria into IBS with predominant constipation , IBS with predominant diarrhea, IBS with mixed bowel habits, and unclassified IBS. In addition, IBS occurring subsequent to gastrointestinal infections is known as post infectious-IBS (PI-IBS). The rationale behind these different sub-types is to maintain consistency of patient selection. This increases understanding of pathophysiological mechanisms, aids in effective diagnosis, treatment, and patient recruitment for clinical trials.

Classification

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

Types

• Classification based on etiology .
  • Intussusception can be classified into 2 types based on etiology.
    • Idiopathic
      • In this there is no clear trigger point.
      • Most commonly seen in children.

Lead point

• In this there is a clear pathologic trigger.
• Most commonly seen in adults.

Children

Idiopathic- no lead point

Pathologic- Lead point
