Intussusception can also prevent food or fluid from passing through the intestines, causing an obstruction.

套叠也会使食物和液体无法通过道，梗阻。

Could be a precursor to intestinal intussusception.

可套叠的前兆。

A barium or air enema, can be used to unfold the intussusception, especially in children.

钡剂或空气灌可复位套叠管，尤其适用于儿童。

Although these are well known mechanisms for intussusception, the majority of cases are considered idiopathic, meaning that they happen without a clear cause.

以上关于套叠的已知机制，但大多数病例特性的，意味着没有明确的病因。

Alright, as a quick recap, intussusception happens when part of the intestine slides into an adjacent part of the intestine, a process called telescoping.

好，快速回顾一下：套叠指部分管套入邻近管中，这个过程称为伸缩。

Intussusception can lead to intestinal obstruction and can also cut off the blood supply to that part of the intestines, resulting in bowel ischemia.

热并不常见，但情况严重时，如梗死，道屏障受损，细菌进入体内败血症和热。

Risk factors include having had one previously or having a sibling with intussusception, as well as having intestinal malrotation - which is a condition where the intestine doesn't rotate correctly during fetal development.

危险因素包括曾有类似病史、家族中兄弟姐妹患过套叠、以及旋转不良，一种由胚胎期道正常旋转停滞所致的疾病。
