Intussusception in a young female with Vibrio gastroenteritis and diabetic ketoacidosis.

The incidence of functional intussusception is extremely rare in adults. A 23-year-old woman, previously diagnosed with type 1 diabetes mellitus (DM), complained of colicky abdominal pain associated with vomiting of 1-day duration. Currant jelly stool was observed. Irrespective of hydration and intravenous insulin injection under the diagnosis of diabetic ketoacidosis (DKA), her abdominal pain and laboratory parameters did not improve. Abdominal computerized tomography (CT) revealed a jejunojejunal intussusception. We maintained large-volume fluid administration, and her abdominal pain began to subside. The stool culture was positive for Vibrio parahaemolyticus. We confirm the intussusception that was resolved by supportive management without surgical intervention in a patient with gastroenteritis and diabetic ketoacidosis.
