RESUMO
Introduction: Intussusceptions in adults are rare, representing 1% to 5% of intestinal obstructions in this age group. This condition can be caused by benign and malignant lesions acting as lead points, the latter being the most frequent. Furthermore, the diagnosis is challenging due to the non-specific symptoms with variable duration. Case Presentation: A 43-year-old man, with a history of localized clear-cell renal carcinoma (ccRCC) treated 9 years earlier with a right radical nephrectomy, presented with bowel obstruction symptoms. An abdominal computed tomography scan showed an ileocolonic intussusception. Hence, the patient required a right hemicolectomy with ileotransverse anastomosis. The histopathological analysis showed a metastatic ccRC to the terminal ileum causing the intussusception. Discussion: Adult intussusceptions are rare. However, they should be considered in the differential diagnosis of patients with abdominal pain and symptoms of bowel obstruction. Metastases of renal cancer to the small bowel are uncommon and even more so in the form of intussusception. Definitive treatment must be tailored to the patient's condition and underlying cause. (AU)

RESUMEN La invaginación o intususcepción intestinal es rara en adultos, el 5 % la padecen y constituye el 1 % de las obstrucciones intestinales. Su presentación clínica es muy variada, puede presentarse como obstrucción intestinal aguda o con obstrucción parcial y recurrente, los estudios de imágenes juegan un papel crucial en el diagnóstico. El 90 % de los pacientes presentan una causa subyacente, por el cual la mayoría se acompaña de resección intestinal.
ABSTRACT Intussusception or intestinal intussusception is rare in adults, 5% suffer from it and constitutes 1% of intestinal obstructions. Its clinical presentation is very varied, it can present as acute intestinal obstruction or with partial and recurrent obstruction, imaging studies play a crucial role in the diagnosis. 90% of patients have an underlying cause, for which the majority is accompanied by intestinal resection.
RESUMO
Objective To improve diagnosis and therapy of intussusception in adult.Methods The clinical datas of 57 hospitalized cases with intussusception in adult were collected from Jan.1997 to May. 2006.Results 19 cases were diagnosised preoperation37 of 57 cases wereoperated on ,among them ,11 cases benigh,26 cases with malgnent disease.2 cases died of serious condition,the others recovery smoothly, 43 cases followed up for 8 mon to 8 years without relapse one.Conclusions The key is to emphasis on the disease and the primary choice was to operat on.
