Meckel’s diverticulum − a congenital defect of the gastrointestinal tract underestimated in differential diagnostics. own experience

Meckel’s diverticulum is a vestigial remnant of the omphalomesenteric duct. It is the most frequent defect of the gastrointestinal tract and is present in approx. 2% of the population: more often in boys than in girls, at a 3:1 ratio. Meckel’s diverticulum causes clinical symptoms only in 4-6% of individuals. It is situated approximately 60-100 cm away from the Bauhin’s valve. The wall of Meckel’s diverticulum consists of all layers typical of the small intestine. It is usually approx. 2-3 cm long, but it can reach lengths of over 10 centimetres. It is usually set on a narrow base. Related symptoms usually occur by the 2^nd-3^rd year of life and have an acute character. They may occur in older children, which must be remembered in differential diagnosis. An example can be the case of an 8.5-year-old boy with symptoms indicating obstruction of the gastrointestinal tract in which a large, atypically accreted and partly twisted Meckel’s diverticulum was found with strangulation of the small intestine between the diverticulum and the mesentery.
