Background: Meckel's diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1-3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult.

Methods: We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel's diverticulum causing intussusception.

Conclusions: Intestinal obstruction in patients with Meckel's diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture. Conclusions: Consideration of Meckel's diverticulum although a rare diagnosis is imperative and this case raises the question "should surgeons routinely examine the bowel for Meckel's diverticulum at laparoscopy?"
