Objectives. From a personal series of 217 pediatric cases and a meta-analysis of 8 389, the author made a study of the uniqueness embryopathogenique in clinical and surgical correlations. XResults. With a frequency of 1.69% with a male General Sex Ratio 1.9, Meckel's diverticulum dominates the abdominal surgical pathology by its deceptive nature, << too often silent and discovered incidentally, that loud and updated at the opportunity of a complication >>. The author focuses on the forms << variants >>, in particular the << Meckel equivalent >> DM << at minimum >>, DM << plated >>, << mesenteric included or also called DM intraluminal >>, each form can cause its own complications. Mechanical complications (intussusception, volvulus diverticular axial or flange Littre hernia) remain the most frequent (62.7%). Hemorrhagic stroke, abrupt or insidious complement the complications, but there is no clinicopathological parallelism in the same way that no histo-clinical parallelism. Conclusions. Its clinical masks and diagnostic pitfalls can be appreciated by applying the << Rule of 2 >> applying to eight parameters (frequency, age, sex, clinic, office, size, diameter, heterotopia) in connection with the notion of << second appendix >> of the ancient authors. Therapeutic rule should not not derogate from the dogma of the T resection with end to end anastomosis in open surgery, laparoscopy still only a great ally.
