A case of jejuno-jejunal intussusception caused by a small intestinal lipoma / 대한내과학회지

ABSTRACT

Intussusception is a prolapse of a segment of the intestine into the lumen of the adjacent intestine. The majority of intussusceptions occur in infancy and early childhood. Intussusception arising in adulthood represents only about 5% of all intussusceptions and is usually caused by a malignant small bowel lesion acting as an apex for intussusception. Lipoma is not a common tumor in the gastrointestinal tract, and gastrointestinal lipomas may be submucosal or subserosal. Most of them are asymptomatic, although they may cause abdominal pain, bowel obstruction, and gastrointestinal bleeding. Intestinal intussusception caused by lipoma is uncommon and is particularly rare when the lipoma is located in the small intestine. We report an unusual case of intussusception in an adult male patient, which was caused by a lipomatous lesion located in the proximal jejunum acting as a lead point.
