Current Operative Management of Meckel Diverticulum
Meckel diverticulum is a true diverticulum, containing all layers of the bowel wall. It results from failure of the omphalomesenteric duct to regress. The incidence is estimated to be 1–2%, though the true rate is unknown as only approximately 4% are symptomatic and the risk of developing symptoms decreases with age. While the actual values vary, the often taught “rule of 2s” remains useful: the incidence is 2%, the male to female ratio is 2:1, the presentation is mostly before 2 years of age, the location is within 2 ft. (60 cm) from the ileocecal valve, and they are approximately 2 cm in diameter and 2 in (5 cm) long and can contain two types of heterotopic mucosa.
