Meckel’s diverticulum is a congenital true diverticulum of the distal ileum, occurring in 2-3 % of the population. It is a vestigial remnant of the omphalomesenteric duct, which normally becomes obliterated between the fifth and the seventh week of gestation. The diverticulum is usually localized within 100 cm of the ileocecal valve and may contain heterotopic gastric mucosa. Symptoms are uncommon, and most Meckel’s diverticula are incidentally found during autopsy, surgery, or barium studies. Symptoms are typically related to the onset of complications (4-40 % of patients), which may manifest as acute abdomen. Complications may occur at all ages, but they are more common in children than adults. In the pediatric population, hemorrhage is the most frequent complication, followed by bowel obstruction and inflammation. Diagnosis is difficult, but ultrasonography represents the first-level diagnostic method in emergency.

Abstract
Meckel’s diverticulum is a congenital true diverticulum of the distal ileum, occurring in 2-3 % of the population. It is a vestigial remnant of the omphalomesenteric duct, which normally becomes obliterated between the fifth and the seventh week of gestation. The diverticulum is usually localized within 100 cm of the ileocecal valve and may contain heterotopic gastric mucosa. Symptoms are uncommon, and most Meckel’s diverticula are incidentally found during autopsy, surgery, or barium studies. Symptoms are typically related to the onset of complications (4-40 % of patients), which may manifest as acute abdomen. Complications may occur at all ages, but they are more common in children than adults. In the pediatric population, hemorrhage is the most frequent complication, followed by bowel obstruction and inflammation. Diagnosis is difficult, but ultrasonography represents the first-level diagnostic method in emergency.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
