A Surgical Conundrum in Feeding Jejunostomy-Jejunojejunal Intussusception: A Case Series.

Intussusception is a common cause of intestinal obstruction in the pediatric population. Usually, it is primary and benign and can be managed by nonoperative interventions in 80% of the cases. Adult intussusception accounts for only 5% of all cases of intussusception and 1%-5% of all cases of intestinal obstruction. Unlike in the pediatric population, intussusception in adults is usually caused by a pathologic lead point. The initial investigation to diagnose it is an ultrasound abdomen followed by contrast-enhanced computed tomography (CECT) of the abdomen. The placement of an intestinal tube for feeding purposes has been rarely reported as a cause of intussusception. Here, we present a case series of four patients who had jejunojejunal intussusception following the placement of feeding tubes into the jejunum. Three patients were operatively managed and one was managed conservatively.
