Intussusception in the Adult

Abstract

lntussusception in the adult is an uncommon cause of intestinal obstruction. Seventeen cases were seen at two teaching hospitals over a twenty-year period. A local causative lesion was preent in all cases; a malignant tumour was present in two out of seven intussusceptions arising in the small intestine and in seven out of ten arising in the large intestine. More than half the cases had a protracted clinical course prior to diagnosis.

Clinical Entity and Treatment Strategies for Adult Intussusceptions: 20 Years' Experience

“…Lipomas were the most common enteric lesions in our study, not metastatic tumors as has been reported in other studies. 1,3,22 Adenocarcinomas (80 percent) are the most prevalent pure malignant colonic lesions. 1,3,22 There also were four idiopathic intussusceptions (16.7 percent) in our study.…”

A Case of Multiple Intussusceptions in the Small Intestine Caused by Metastatic Renal Cell Carcinoma

“…Intussusception is a rare entity in adults and it accounts for one percent of all the cases of bowel obstruction (12). The intussusception in adult patients is often difficult to diagnose preoperatively, and the diagnosis is most often established at the time of surgery.…”

Association of Intussusception and Celiac Disease in Adults

“…A structural lesion or lead point is only identified in 5-15% of cases, and the majority of cases ([80%) resolve with conservative management [1,2]. In contrast, adult intussusception is uncommon (approximately 5% of all cases) and is thought to be due to structural lesions in over 80-90% of cases in retrospective series of surgical cases [3][4][5][6][7]. While this data has been supported by retrospective reviews in the surgical literature, more recent reviews of intussusception identified on imaging studies found that only 30% of patients had an identifiable lead point, and that over 50% of patients without an identifiable lead point had ''idiopathic'' intussusception [8][9][10][11].…”
