We present the case report of a 24-day-old infant admitted to the Department of Paediatric Surgery in order to treat suspected obstruction of the gastrointestinal tract. For two days prior, the patient had experienced gas and stool retention. On the day of admission, vomiting occurred with gastric contents, later followed by faecal. Ultrasound and scout film of the abdomen were performed, showing radiological features of obstruction of the gastrointestinal tract. The newborn was urgently referred for surgery. The procedure was performed under general anaesthesia. Intraoperatively, at the level of the ileum, 5 cm before the cecum, obstruction of the gastrointestinal tract was found in the form of a lesion resembling Meckel’s diverticulum. Resection of the lesion was performed and end-to-end ileoileal anastomosis was formed. The resected lesion was sent for histopathological examination, which revealed a cystic duplication of the gastrointestinal tract.
