The etiology of intussusception is still unclear, 80%-90% of adult intussusception is caused by organic lesions such as tumors, and the majority of pediatric intussusception is primary. It is generally believed that the loss of rhythm of intestinal peristalsis and spasm of the intestinal loop muscles may be related to the following factors: 1, change in the nature of the diet, such as the addition of complementary foods.
2, the infant ileocecal part of the mobility is large, ileocecal valve hypertrophy, the area is rich in lymphoid tissue, inflammation or food stimulation easily caused by congestion, edema, intestinal peristalsis easy to push the ileocecal valve forward, and pull the intestine to form intussusception. Other authors believe that it is related to adenovirus and rotavirus infection in the intestinal tract. Secondary intussusception is less common in children.
It is simple and intuitive, with typical images, and the mass site and reset can be tracked during the reset, and the effect of barium enema and air enema on human body can be avoided.
In the treatment process should pay attention to the following aspects of the situation: 1, pay attention to the observation of the sheath of the sleeve water filling, such as crying children with increased abdominal pressure, should stop the injection of saline, to prevent excessive local pressure caused by medical intestinal perforation.
2, for infants of low age, perfusion pressure <70mmHg, the amount of saline injection (<500ml). Because of the thin intestinal canal and thin wall of infants, it is easy to occur blood flow disorders leading to intestinal necrosis and intestinal perforation. 3.If the intestinal mass is fixed in a certain position, it is difficult to withdraw from the set, attention should be paid to maintain the normal pressure range for 5-10 minutes to improve the success rate of intestinal tube release. 4.Parents are advised to tilt the child’s head to one side during the operation to avoid choking due to the increased abdominal pressure of the enema. 5. Observe the abdominal condition of the child and whether there is active charcoal in the stool 6-8h after the reset to exclude incomplete reset of the intestinal sleeve and the occurrence of intussusception again.
