Abstract
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 of Qatar. Methods: We retrospectively reviewed cases of intussusception in children younger than 14 years. Children were treated between 2002 and 2012 at a single hospital in Qatar. 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 and four 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 than that 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 the Arabic Gulf area and developing countries.

Accurate estimates of the baseline incidence of childhood intussusception could help safety monitoring after introduction of rotavirus vaccines
All medical records of hospitalized children aged less than 14 years at Hamad General Hospital (HGH) were reviewed for the period from January 2002 through to December 2012, to identify patients who met the clinical case definition of intussusception as defined by the Brighton Collaboration
23% of children were less than 6 months old, 56% were 6 months to 1 year old, and 26% were older than 1 year old at the time of diagnosis (Figure 1, Table 1)

How to cite this paper: Abbas, T.O., et al (2014) Retrospective Surveillance over 11 Years for Intussusception in Children Younger than 14 Years in the State of Qatar. In only approximately 6% of cases (ranging from 1.5% to 12%), intussusception is associated with a pathological lead point, predominantly Meckel’s diverticulum [12]. The epidemiological features of intussusception recurrence and surgical reduction are not well understood [14]
