Meckels Diverticulum

This is usually found on the antimesenteric side of the ileum and is a remnant of the vitelline duct. It is the most common cause of lower GI bleeding in children. Presentation ranges from asymptomatic to pain and bleeding. There is ectopic gastric mucosa in approximately half of all Meckel's. The Rule of Twos states that it is usually two inches in length, within two feet of the ileocecal valve, two percent of patients are symptomatic, and two times more common in males. It's diagnosis can be confirmed by technetium pertechnetate scan. Surgical therapy involves wedge resection with transverse closure or sleeve excision and end-to-end anastomosis if the base of the diverticulum is wide.
