Meckel's Diverticulum (MD) originates from the incomplete obliteration of the omphalomesenteric duct during the seventh week of gestation. The classic clinical description of MD follows the "rule of two: 2% of the population, 2 inches in length, 2 feet from the ileocecal valve, a 2:1 ratio between males and females, and presentation at two years of age. This study evaluates to what extent the "rule of two" applies to a Spanish pediatric cohort.
