[Adult ileocaecal and colic invagination: a case report].

Intestinal invagination or intussusception is the telescoping of a segment of the intestinal tract into an adjacent one. In most cases the invagination is ileocolic, consisting of the small intestine penetrating into the colon through the ileocaecal valve; in other cases it could be ileoileal or colocolic. It is a common entity in paediatric subjects, especially in the first two years of life (90-95% of cases), but is a rare condition in the adult where it accounts for only 5-10% of all intestinal invaginations and around 1% of all intestinal occlusions. We report a case observed in a 65-year-old patient. The patient underwent ileo-caeco-colic resection. Histological examination of the specimen showed an ulcerated submucosal intestinal lipoma. Computed tomography is the most accurate imaging technique for intestinal invagination. The recommended treatment of adult intestinal invagination is surgical resection of the intestinal segments involved.
