Abstract:
Objective To understand the epidemiological and clinical characteristics of ＜ 2 years old children hospitalized due to intussusceptions.Methods Clinical and demographic data of ＜2 years old children hospitalized due to intussusception between January 2007 and August 2013 were retrospectively collected in Affiliated Children' s Hospital of Soochow University in Suzhou.The incidence data,age distribution,seasonality and clinical characteristics of hospitalized intussusceptions cases were analyzed.Results A total of 594 intussusception-related hospitalizations were identified during this period in children aged ＜2 years,no death occurred.The crude incidence of hospitalized intussusception was 57.3 per 100 000 in children aged ＜2 years (95％CI:52.8-62.1),and 100.6 per 100 000 in children aged ＜1 year (95％CI:92.1-109.8).The male to female ratio was 1.90 ∶ 1.Up to 85.4％ (507/594) of the cases were aged ＜ 1 year,and 66.2％ (393/594) of the cases were aged 3-8 months.The incidence peaked in age group 5-8 months.The median age of the cases was 6.8 months (QR=4.4),and increased from 6.3 months (QR=4.2) in 2007 to 7.3 months (QR=4.0) in 2013.No obvious seasonality was observed.Main symptoms or signs included vomiting (83.2％,494/594),abdominal mass (81.1％,482/594),and bloody stool (64.5％,383/594).Abdominal ultrasonic testing was the most frequently used diagnostic approach (98.7％,586/594).Up to 86.2％ (512/594) of patients were successfully treated by surgical intervention.The main sites for acute intussusception in children aged ＜2 years were ileo-colic (34.5％,183/530),ileo-ileo (30.8％,163/530) or ileo-ileo-colic (27.9％,148/530).Conclusion The incidence of hospitalized intussusception in children aged ＜2 years was high in Suzhou.It is necessary to establish an active surveillance system to provide baseline data for the evaluation of rotavirus vaccine safety.
