1, a section of the intestine into its connected intestinal lumen is called intussusception A section of the intestine into its connected intestinal lumen is called intussusception. According to the occurrence of the part can be divided into ileocecal, small intestine and colonic overlap and other types. 2, a variety of reasons can cause pediatric acute intussusception Most of the causes of pediatric acute intussusception are due to viral and bacterial infections resulting in the consequences of intestinal dysfunction, and a few are due to congenital intestinal malformations, tumors and other abdominal organic lesions. 3, intussusception can cause abdominal colic intussusception can cause abdominal colic, manifested as the original quiet children suddenly appear obvious irritability and discomfort, there may be general ankylosis. The legs are flexed to the abdomen, the expression is painful, and the symptoms are sudden and abrupt; the small infants who cannot express themselves appear to cry in paroxysms, and perform normally or sleep quietly between attacks. As the disease progresses, indifference and drowsiness may occur between episodes of abdominal pain. Vomiting is common, starting with undigested food, followed by vomiting of bile-like material, which may be followed by generalized writhing and breath-holding. At the beginning of intussusception, the child excretes a small amount of normal stool, and later blood appears in the stool, followed by dark red blood clots or jam-like stool due to intestinal ischemia and necrosis. 4, pediatric intussusception treatment is divided into conservative treatment and surgical treatment treatment is divided into conservative treatment and surgical treatment. The majority of children who are seen in time can be cured by conservative treatment. A part of the late diagnosis of children need to be cured by surgical treatment. Intussusception due to organic abdominal pathology also requires surgery to resolve the original pathology in order to cure.
