[Intestinal occlusion caused by persistent omphalomesenteric duct and Meckel's diverticulum: report of 2 cases].

Two rare cases of mechanical intestinal obstruction due to an omphalomesenteric duct remnant and/or to a Meckel's diverticulum, respectively, are reported. The first case was a 20-year-old man and the second an 87-year-old woman. In contrast with various reports in the literature, our experience demonstrates that this kind of obstruction may also affect elderly female patients in western countries.
