The intussusception (IIA) is an invagination of the immediate part of the intestine. She is responsible for a syndrome with an occlusive venous compression and swelling that can rapidly progress to intestinal necrosis. Most cases occur in children aged 6 to 18 months and occur more frequently in boys than girls. There are two types of IIA: the IIA idiopathic representing 90-95% of invaginations of the child and the IIA secondary to local injury of the gastrointestinal tract or occurring in a particular context whose frequency are between 5 and 10%. The pathogenesis of the IIA remains uncertain, but the infectious origin is criminalized in most idiopathic invaginations. This component is dominated by viral agents including adenovirus, rotavirus, enterovirus, human herpesvirus 6 and 7, cytomegalovirus and Epstein-Barrvirus. Bacterial agents are rather found and include Yersinia enterocolitica, Staphylococcus aureus, Escherichia coli O157, H7, Salmonella and Campylobacter. In a small proportion parasitic agents may be reported in the IIA, the most frequently found are Entamoeba histolytica, Trichuris trichuira, Ascaris lumbricoides, Ankylostoma and Giardia.
肠套叠（IIA）是一段肠管的紧邻部分发生套入。它会引发一种伴有闭塞性静脉受压和肿胀的综合征，可迅速发展为肠坏死。大多数病例发生在6至18个月大的儿童中，男孩比女孩更易发病。IIA有两种类型：特发性IIA占儿童肠套叠的90 - 95%，继发性IIA继发于胃肠道局部损伤或发生在特定背景下，其发生率在5%至10%之间。IIA的发病机制尚不确定，但在大多数特发性肠套叠中，感染源被认为是致病因素。这一因素以病毒为主，包括腺病毒、轮状病毒、肠道病毒、人类疱疹病毒6型和7型、巨细胞病毒和爱泼斯坦 - 巴尔病毒。细菌也有发现，包括小肠结肠炎耶尔森菌、金黄色葡萄球菌、大肠杆菌O157、H7、沙门氏菌和弯曲杆菌。在一小部分肠套叠病例中可能会报告寄生虫感染，最常见的是溶组织内阿米巴、鞭虫、蛔虫、钩虫和贾第虫。
