Abstract

PURPOSE
The aim of this study was to evaluate the sensitivity and specificity of ultrasonography of suspected ileocolic intussusception performed by emergency medicine (EM) residents who participated in a 2-hour focused ultrasound training program for intussusception.
METHODS
This was a 16-month retrospective, observational study. Pediatric patients with suspected ileocolic intussusception who underwent ultrasound performed by second or third year EM residents were included in the study. The gold standard was a diagnostic work-up performed by a radiologist or clinical follow-up, compared with the results of ultrasonography performed by EM residents.
RESULTS
A total of 38 patients were enrolled. The sensitivity of ultrasound performed by emergency medicine residents for prediction of ileocolic intussusception was 92.86%(66.13% to 99.82%), the specificity was 91.67%(73.00% to 98.97%), the positive likelihood ratio was 11.14(2.93 to 42.34), and the negative likelihood ratio was 0.08(0.01 to 0.52).
CONCLUSION
Emergency residents can identify ileocolic intussusceptions with only minimal training, which could substitute for ultrasonography performed by radiologists when they are not immediately available.
