Meckel's Diverticulitis

Aka: Meckel's Diverticulitis, Meckel's Diverticulum, Meckel Diverticulum
  1. See Also
    1. Appendicitis
  2. Epidemiology
    1. More common in males by ratio of 3:2
    2. Lifetime complication rate: 4%
      1. More than 50% of complications occur before age 10
  3. History
    1. Initial report by Hildanus in 1598
    2. Detailed description by Johann Meckel in 1809
  4. Pathophysiology: Meckel's Diverticulum
    1. Incomplete vitelline duct (omphalomesenteric) closure
    2. Location
      1. Proximal to ileocecal valve by 100 cm
      2. Usually within 45 to 60 cm of ileocecal valve
  5. Differential Diagnosis of Meckel's Diverticulitis
    1. See Appendicitis
  6. Complications of Meckel's Diverticulum
    1. GI Bleeding (25-50% of complications)
      1. Often associated with ectopic gastric mucosa
      2. Hemorrhage is most common presentation under age 2
    2. Meckel's Diverticulitis (10-20% of complications)
      1. Similar in presentation to Appendicitis
    3. Bowel Obstruction
      1. Volvulus at fibrotic band attached to abdominal wall
      2. Intussusception
      3. Incarcerated Inguinal Hernia (Littre's Hernia)
    4. Other complications
      1. Carcinoid Tumor
  7. Radiology
    1. Radionuclide Scintigraphy (Sodium Tc-pertechnetate)
      1. Preferential uptake by gastric tissue
      2. Most accurate test in Meckel's Diverticulum
        1. Test Sensitivity: 85% in children
        2. Test Specificity: 95% in children
      3. Less accurate in adults
        1. Cimetidine increases accuracy in adults
    2. Small Bowel enema
      1. Indicated for negative scintigraphy in adults
    3. Arteriography (indicated for acute Hemorrhage)
    4. Tests not useful in evaluation for Meckel's
      1. CT Abdomen
      2. Ultrasound
      3. Abdominal XRay
  8. Management: Meckel's Diverticulum
    1. Symptomatic (e.g. Meckel's Diverticulitis)
      1. Prompt surgical resection
    2. Asymptomatic incidental finding on other surgery
      1. Prophylactic resection recommended

Meckel Diverticulum (C0025037)

Definition (MSHCZE) Vrozený divertikl vyskytující se u některých osob na tenkém střevě jako zbytek embryonální tkáně. Může být zdrojem zánětu, krvácení nebo střevní neprůchodnosti. Je přítomen cca u 1% populace. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI) A congenital pouch in the distal ileum. It may cause painless rectal bleeding and bowel obstruction.
Definition (MSH) A congenital abnormality characterized by the outpouching or sac formation in the ILEUM. It is a remnant of the embryonic YOLK SAC in which the VITELLINE DUCT failed to close.
