MRCP revision battle 53.6: Meckel's diverticulum

Meckel's diverticulum is the vestigial remnant of the vitellointestinal duct.

Its features are often recalled as a series of '2s':
  • found in 2% of the population
  • around 2 inches long
  • at 2 foot from the ileocaecal valve

It may present with:
  • painless rectal bleeding
  • GI obstruction
  • abdominal pain due to faeces trapped inside diverticulum

Investigation is with radionucleotide scan.

Treatment for complications is surgical.

Now to end on an unusual condition - cat scratch disease.
