Abstract

Introduction:

Ileocolic intussusception is a common cause of pediatric bowel obstruction in youngchildren but can be difficult to diagnose clinically due to vague abdominal complaints. If left untreated,it may cause significant morbidity. Point-of-care ultrasound (POCUS) is a rapid, bedside method ofassessment that may potentially aid in the diagnosis of intussusception. The purpose of this systematicreview and meta-analysis was to determine the diagnostic accuracy of POCUS for children withsuspected ileocolic intussusception by emergency physicians (EP).

Methods:

We conducted a systematic search on PubMed, Embase, CINAHL, LILACS, the Cochranedatabases, Google Scholar, as well as conference abstracts, and assessed bibliographies of selectedarticles for all studies evaluating the accuracy of POCUS for the diagnosis of intussusception in children.We dual extracted data into a predefined worksheet and performed quality analysis with the QUADAS-2tool. Data were summarized and a meta-analysis was performed

Results:

Six studies (n = 1303 children) met our inclusion criteria. Overall, 11.9% of children hadintussusception. POCUS was 94.9% (95% confidence interval [CI], 89.9% to 97.5%) sensitive and 99.1%(95% CI, 94.7% to 99.8%) specific with a likelihood ratio (LR)+ of 105 (95% CI, 18 to 625) and a LR− of0.05 (95% CI, 0.03 to 0.10).

Conclusions:

POCUS by EPs is highly sensitive and specific for the identification of intussusception forchildren presenting to the emergency department.
