We here report the case of a 5-years-old child with recurrent abdominal pain and chronic constipation. For that reason, the baby came to our hospital several times with symptoms' resolution after enema. Despite the medical therapy and the instrumental approaches, the situation of the last admission proceeded to intestinal obstruction and therefore to specialistic surgery in emergency during the night, with resolution of the obstruction that was due to a congenital malformation that was gone undiagnosed during pregnancy, at birth and during the previous admissions. Such anomaly is rarely diagnosed after the neonatal period, anyway the present case underlines that this condition must be taken into account in every patient with recurrent abdominal pain and constipation episodes.
