Diagnostic accuracy of ultrasound in diagnosis of intussusception in children considering surgical findings as gold standard.
Pak J Radiol Nov ;32(4):209-12.

ABSTRACT: INTRODUCTION: Intussusception is one of the most common causes of intestinal obstruction in infants and small children. Intussusception is basically a childhood disease with peak incidence between 6 months and 2 years but can also occur in older children. Since intussusception requires a specific treatment, prompt identification is essential. Ultrasound is quick to perform, is non-invasive, does not involve radiation exposure, is cost effective, is easily available everywhere and is not discomforting to the young patient. The rationale of this study was to form a non-invasive easily available modality to diagnose intussusception in children so that timely intervention could be done to reduce morbidity and mortality. MATERIALS AND METHODS: The study was conducted in Department of Radiology, Khyber Teaching Hospital Peshawar from December 2020 to January 2022. We collected total of 251 patients with age range in between 6 months to 5 years. Patients having compatible symptoms like blood in stool and pain abdomen were evaluated by ultrasound by an experienced radiologist. Patients were closely followed to know their true positive and true negative status by either radiological or surgical. SPSS was used for data entry and analysis. RESULTS: The mean age of the sample was 2.9 + 1.4 years. Sensitivity of US was found to be 94.8% and specificity 71.2%. The positive predictive value of the US was 86.1% and negative predictive value is 88.1%. CONCLUSION; Ultrasound is useful diagnostic tool and has an acceptable sensitivity and specificity for the detection of intussusception.
