Retrospective Surveillance over 11 Years for Intussusception in Children Younger than 14 Years in the State of Qatar

摘要

Background: Accurate estimates of the baseline incidence of childhood intussusception could help safety monitoring after introduction of rotavirus vaccines. Therefore, we studied the incidence of intussusception in the state ofQatar. Methods: We retrospectively reviewed cases of intussusception in children younger than 14 years. Children were treated between 2002 and 2012 at a single hospital inQatar. We analyzed information according to age, sex, clinical signs, diagnostic- and treatment-related characteristics, and length of stay. We calculated the national incidence of intussusception using census data. Results: A total of 106 children were diagnosed and treated for intussusception over 11 years. The male to female ratio of intussusception was 1.4:1. The most common symptom was bleeding per rectum (37%). One hundred andfour children with intussusception underwent diagnostic and therapeutic contrast enema, and 31.7% of patients underwent operative management. The length of stay was longer in patients who underwent operative reduction thanthat in those who did not. Conclusions: This is the first study to estimate the incidence of childhood intussusception prior to introduction of rotavirus vaccination in Qatar. A prospective surveillance system using a standardized case definition would be useful for examining the occurrence of intussusception in theArabicGulfarea and developing countries.
