RESUMEN
BACKGROUND: Adult intestinal intussusception is a rare condition caused by the mechanical disruption of bowel motility. A bezoar is defined as indigestible material inside the gastrointestinal tract that develops into a trapped mass; the most frequent bezoar is a trichobezoar. When a trichobezoar extends into the small intestine it is defined as Rapunzel's syndrome. Literature describing complications related to this pathology remains scarce. CASE PRESENTATION: A 16-year-old Mexican girl presented to our emergency room with acute abdomen and a presumptive diagnosis of intestinal obstruction. Computed tomography was suggestive of intussusception. Surgery confirmed a jejunal-jejunal intussusception with a mass within the gastric cavity extending into her small intestine, corresponding to a trichobezoar. A manual intussusception reduction and a gastrotomy with extraction of the trichobezoar were performed. CONCLUSIONS: We present a case of a jejunum intussusception as a complication of Rapunzel syndrome. Our patient had a favorable outcome after surgical intervention with a manual intussusception reduction, with retrograde displacement of the trichobezoar into the gastric lumen, and a complete extraction through a gastrostomy. Follow-up included psychiatric evaluation.
