Clinical Features Of Acute Intussusception In School-age Children

Objective: To explore the clinical features of intussusception in school-age children.Methods: 73 school-age children with intussusception hospitalized by Shenjing Hospital from January 1,2011 to December 31,2015 were retrospected,including clinical manifestation,imaging examination and therapeutic process,to explore the clinical features of intussusception in school-age children.Results: A total of 3042 patients were identified: 73(2.4%)patients were?6 years old,and 2969(97.6%)patients were<6 years old.The clinical symptoms were abdominal pain(68/73,98.2%),vomiting(42/73,57.5%),bloody stools(6/73,8.2%)and palpable abdominal mass(39/73,53.4%).There were 2 children(2.7%)with all the four symptoms.The triad of bloody stools,vomiting and abdominal pain was encountered in 4 children(5.5%)from 73 school-age children with intussusception.72 of 73 school-age children with intussusception underwent a ultrasound examination.And 69 children had a presentation of a target sign or a sleeve sign on ultrasound images.The success rate of enema reduction was much lower in school-age children compared with children younger than 6(79.5%:96.7%).In addition,children in school-age were more likely to undergo operation(20.6%:3.3%)and had a greater rate of bowel necrosis(2.7%:0.3%).The incidence of secondary intussusception was much higher in school-age children than that in children younger than 6(23.3%:1.0%).Excluding secondary intussusception,the success rate of enema reduction in group of school-age children was similar with group of children younger than 6(96.4%:97.4%).Conclusion: The clinical manifestation of school-age children is atypical.The incidence of secondary intussusception is much higher in school-age children than that in children younger than 6.Enema reduction is safe and effective to primary intussusception in school-age children.
