OCAMPO ANDUAGA, Edward et al. Case Reports of Atypical Presentation of Meckel’s Diverticulum. Rev Col Gastroenterol [online]. 2017, vol.32, n.2, pp.166-170. ISSN 0120-9957.  https://doi.org/10.22516/25007440.144.

Meckel’s diverticulum is an embryonic vestibule of the vitelline duct which normally disappears completely between the fifth and seventh week of gestation. It is located at the anti-mesenteric ileal border approximately 60 cm from the ileocecal valve. Its incidence is 2% in the general population with a 2:1 male:female ratio. It has the same layers as the intestinal wall but contains ectopic tissue in approximately half of all cases: gastric tissue in 60% to 82%, pancreatic tissue in 1% to 16% and gastric and pancreatic tissue in 5% to 12% of cases. It is often asymptomatic and is most frequently found during laparotomies and autopsies. While it is true that the vast majority of cases manifest as low gastrointestinal bleeding, there are less frequent forms of presentation such as intestinal obstruction and intestinal perforation. Intestinal obstruction associated with the Meckel’s Diverticulum can occur as a result of herniation or intussusception around the fibrous cord that extends from the abdominal wall to the diverticulum, mesentery, or intestinal segment, which can lead to severe obstructive torsion that sometimes causes necrosis and perforation.

We present five cases of patients with Meckel’s diverticulum with atypical presentations, two with internal hernias, one with intestinal invagination and two with blocked perforation.
