Patent vitelline duct as a cause of acute abdomen: Case report of an adult patient.

A patent vitelline duct is an uncommon condition. Diagnosis is based on clinical and radiological findings. Complications include prolapse, intestinal obstruction, hemorrhage, and perforation. Here, we report the case of a 23-year-old man with patent vitelline duct who presented with umbilical discharge, severe abdominal pain, fever of 38.5°C, no gas/feces passage, and nausea and vomiting for three days. Laparotomy with midline incision was performed because of acute abdomen. A patent vitelline duct from the terminal ileum to the umbilicus was observed. Meckel's diverticulitis and ileus were also noted. En bloc resection of the umbilicus, patent vitelline duct and a 15 cm ileal segment was performed. The patient was discharged five days after the operation.
