Résumé
BACKGROUND: The preoperative diagnosis of adult intussusceptions (AIs) remains difficult, and the assessment of the radiological methods has been evaluated very little in the literature. The aim of this study was to evaluate the interest of the different imaging modalities for the preoperative diagnosis of AI and describe causes of AI. PATIENTS AND METHODS: Consecutive patients of 15 years and older with the postoperative diagnosis of intussusception from 1979 to 2004 were reviewed retrospectively for this multicentric study. Data concerning clinical considerations, morphological examinations, surgical procedure, histological conclusions, mortality rate and recurrence were analysed. RESULTS: Forty-four patients with documented intussusception were included. The mean age was 51 years (15-93 years). The preoperative diagnosis of intussusception was made in 52% of the cases. The sensitivities of the different radiological methods were abdominal ultrasounds (35%), upper gastrointestinal barium study (33%), abdominal computed tomography (CT) (58%) and barium enema (73%). An organic lesion was identified in 95% of the cases. There was 29 enteric and 15 colonic (including appendicular) intussusceptions. Thirty-seven percent of the enteric lesions were malignant, and a bit less than 50% of them were metastatic melanomas. The benign enteric lesions were Meckel's diverticulum and Peutz-Jeghers syndrome in half of the cases. Fifty-eight percent of the pure colonic lesions (excluding appendix) were malignant, and 85% of them were primary adenocarcinomas. The benign colonic lesions were lipomas in 80% of the cases. All patients, except one, had a surgical treatment, and 13 of them had a complete reduction of the intussusception before resection. The mortality rate was 16% and recurrence occurred in three patients; two of them had a Peutz-Jeghers syndrome. CONCLUSION: Intussusception rarely occurs in adults, but nearly half of their causes are malignant. The CT scan is a helpful examination for enteric intussusceptions whether barium enema seems to be the most performing method for colonic lesions. Surgery is the recommended treatment, with or without a primary reduction of the intussusception. During the surgical procedure, this reduction can lead to a more limited bowel resection.
