Can hyperglycaemia cause jejuno-jejunal intussusception?

Ileocolic Intussusception in a Leukemic Adult Patient: A Case Report and Review of the Literature

We present a rare case of intussusception in a 41-year-old man with acute myeloid leukemia without an evidence of leukemic infiltration of the bowel. The patient presented to the emergency room with right lower quadrant pain. Initially he was diagnosed with typhlitis. CT scan was done and showed ileocolic intussusception without a definitive lead point identified. Patient underwent hemicolectomy and histopathological study of the specimen did not show any leukemic infiltrate. High suspicion of intussusception should be kept in mind with leukemic patients presenting with abdominal pain.

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.
