The aim of this work was to retrospectively assess clinical and anatomical features of children with Morgagni congenital diaphragmatic hernias. The study group included 5 boys and 3 girls, aged between 5 months and13 years, at the time of the diagnosis. Morgagni diaphragmatic hernia was diagnosed with non-acute symptoms in 8 children. A retrosternal defect of the diaphragm was left-sided in 7 subjects and bilateral in 1 boy. A hernial sac was found in 6 children. In 3 subjects, the hernial sac contained the liver, in 2 subjects the omentum, in 2 subjects the transverse colon and small intestinal loops and in one child it contained the transverse colon with the omentum. In all cases, the diaphragmatic defect was closed using primary plasty. All subjects healed without complications. A differential diagnosis of congenital Morgagni hernia must be considered in children with unusual respiratory and gastrointestinal symptoms with abnormal x-ray findings on chest examination. A stricture of the congenital Morgagni diaphragmatic hernia is rare, and was not recorded in our group.
