Background

  • Most common cause of intestinal obstruction in 3mo-6yr
    • Usually occurs in 3-36 months
  • Due to telescoping of one part of intestine into another
    • Mesentery involvement > ischemia, bloody/mucous stool
  • Peds - typically no pathological lesions
  • Adults
    • Rare
    • 80% involve small bowel

Diagnosis

  • Classic Triad:
    • Sudden colicky pain
    • Palpable sausage shaped mass on right
    • Currant jelly stool (only 50% of cases)
  • Intermittent episodes of pain
    • Child pulls up knees
    • May be asymptomatic between episodes
    • Later stages may be associated with lethargy
  • Guaiac-positive stool (~50%)
  • Adults
    • Typically have partial/SBO symptoms
    • Vomiting, rectal bleeding, constipation
    • Distended
    • Late Stage: sepsis
    • Large bowel obstruction associated with malignancy
  • Imaging
    • Ultrasound
      • Sensitivity and specificity approach 100%, but operator dependent
      • Classically see bulls eye lesion
    • Air contrast enema
      • Diagnostic and frequently curative
      • Prior to procedure, IV hydration, NG tube decompression, surgery consult
    • CT for adults (air contrast or barium enemas not sufficient)[1]
      • Up to 20% of cases don't have lead point
      • 70% risk of malignancy
  • All labs nonspecific

Differential Diagnosis

Pediatric Abdominal Pain

0–3 Months Old

3 mo–3 y old

3 y old–adolescence

Treatment

  1. Stable patients with a high clinical suspicion and/or radiographic evidence of intussusception and no evidence of bowel perforation should be treated with nonoperative reduction.
    1. NPO/NG tube
    2. Air-contrast enema (reduces 80%)
  1. Surgery consult
    1. Surgery is indicated when nonoperative reduction is incomplete.
    2. In stable, asymptomatic patient with ileo-ileo intussusception, short length of intussusception <2.3 cm, expectant management is reasonable as many of these cases will resolve spontaneously

Disposition

  • Admit
  • Recurrence occurs in ~10% of cases reduced by enema
    • initial management same
