Objective: To enumerate the cases of intussusception in Chennai during 2012-2013, describe the clinical profile, outcomes of case management and highlight the importance of systematically collecting this data in lieu of rotavirus vaccine introduction in India.
Methods: Medical records of pediatric intussusception cases admitted in eight large hospitals in Chennai from July 2012 through June 2013 were retrospectively reviewed. Demographic and clinical data including diagnostic and treatment practices were obtained. Cases were categorized based on the diagnostic certainty criteria stipulated by the Brighton collaboration on intussusception.
Results: During the one year of study period, 205 cases of intussusception were diagnosed in 8 hospitals in Chennai city of India. The median age at presentation was 9 mo (Inter Quartile Range, IQR 6-14) with a male to female ratio of 1.8:1. The commonest site of intussusception was ileocolic (80.4 %). Most of the cases (59.8 %) were managed non-surgically. Direct surgical intervention was carried out in 26.5 % cases whereas in 11.8% of cases, surgery was required after failure of non-surgical measures. Median duration of hospital stay was 3 d (IQR 1-5).
Conclusions: This study documents the case burden of intussusception among children in Chennai in a calendar year. Data on receipt of rotavirus vaccine was not available. The authors recommend collection of rotavirus vaccine data among all cases of intussusception in the country, and do retrospective analysis in other parts of the country and prospective surveillance in pediatric / immunization clinics to assess impact of rotavirus vaccine on intussusception rates in the post rotavirus vaccine introduction scenario.
