However, it was noticed later, that when the infant strained or cried, a thick, bubbling and offensive green-brown discharge came out of the clamped umbilical cord with umbilical flatus. An ultrasound abdomen and umbilical cord confirmed the presence of a persistent omphalomesenteric duct (POMD). He was then transferred to the paediatric surgical unit. There, he underwent a laparotomy and surgical resection of the POMD and was discharged home 2 days later.
