Multiple intestinal intussusceptions as a complication of severe hyperglycemia in a patient with diabetic ketoacidosis.

Intussusception in adults is a rare phenomenon, occurring in approximately 1 in 30,000 hospital admissions annually. When it does occur, the majority of cases involve an organic lesion serving as a lead point for intussusception, such as tumors or postoperative adhesions. In a small percentage of cases, a lead point is not found, and intussusception is thought to be idiopathic or secondary to a disease process contributing to dysrhythmic peristalsis of the gastrointestinal tract. A few cases of functional intussusception have been reported as being secondary to severe hyperglycemia and metabolic derangements, including metabolic acidosis and hyperkalemia, by causing impaired gastrointestinal motility. We present a case of a 23-year-old Caucasian male who presented with severe hyperglycemia and diabetic ketoacidosis. Imaging of the abdomen revealed three intussusceptions involving the small intestine, which were easily reduced manually during exploratory laparotomy.
