Polyps in the Utsunomiya et al study patients occurred as follows:

  • Small intestine: 64% of patients
  • Colon: 63.2% of patients
  • Stomach: 48.6% of patients
  • Rectum: 32% of patients

The incidence of polyps within the small intestine is greatest in the jejunum and progressively decreases in the ileum and duodenum. [20, 47, 59, 60, 61, 62]
