Abstract

Objective: To assess the relationship between bacterial enteritis and intussusception.

Study design: The Patient Administration Systems and Biostatistics Activity database from January 2002 to December 2005 was examined for clinic visits or hospital admission to a Department of Defense medical facility for children age 0-5 years. The study included the International Statistical Classification of Diseases and Related Health Problems diagnosis-related group (DRG) codes for infections with Yersinia enterocolitica, Escherichia coli, Shigella species, Salmonella species, and Campylobacter. Identified patients were then assessed for the intussusception DRG code for 0-180 days postinfection. The total number of children enrolled in military treatment facilities in the same age group (denominator) was obtained.

Results: Bacterial enteritis significantly increased the relative risk of intussusception. An increased risk was found following infection with Salmonella, E coli, Shigella, and Campylobacter. The relative risk for intussusception following any bacterial enteritis was 40.6 (95% confidence interval = 28.6-57.5; P < .0001).

Conclusions: Bacterial enteritis is a significant risk factor for the subsequent development of intussusception in children.
