[Intussusception in adults. Case report with uncommon etiology and review of the literature].

OBJECTIVE: To present a case of adult intussusception with uncommon etiology.
BACKGROUND: Intussusception is a relatively common cause of intestinal obstruction in children, but is a rare clinical entity in adults, representing less than one per cent of intestinal obstruction in this patient population.
METHOD: We report on 72-year old female patient with intestinal obstruction due to ileocolic intussusception related to leiomyosarcoma of the terminal ileum. A synchronic adenocarcinoma in the cecum was identified. The patient underwent right hemicolectomy and terminal ileum resection with primary anastomosis. Her postoperative course was uneventful. The patient is free of all evidence of disease at 2 year of follow-up. A thorough review of the literature of adult intussusception was carried out.
CONCLUSION: From this review, the recommendation is to resect all cases of adult intussusception, different from the recommended approach in pediatric population.
