A peculiar cause of small-bowel intussusception and iron deficiency anaemia

Abstract

Small-bowel intussusception is much less common in adults than in the pediatric population [ [1] Marinis A. Yiallourou A. Samanides L. et al. Intussusception of the bowel in adults: a review. World J Gastroenterol. 2009; 15: 407-411 Crossref PubMed Scopus (383) Google Scholar ]. Intussusception may be classified on the basis of whether is present a lead point due to an intraluminal lesion that can be either benign (lipoma, adenoma, hamartoma, leiomyoma and hyperplastic polypsadenomatous polyp, inflammatory bowel disease, efferent loop of gastrojejunostomy with intestinal intubation) or malignant (metastasis, lymphoma, adenocarcinoma, mesothelioma, leiomyosarcoma, gastrointestinal stromal tumour, carcinoid tumour) [ 2 Wang N.

Intussuception without any identifiable lead point is defined idiopathic and is commonly ascribed to dysrhythmic contractions, sometimes triggered by post-operative adhesion formation, and could be transient [ [5] Kim Y.H.
