Insights
Ultrasonography effectively diagnoses intussusception in children, showing high accuracy. This imaging technique aids in early detection and prompt treatment, reducing potential complications.
Area of Science:
- Pediatric Radiology
- Gastrointestinal Imaging
Background:
- Intussusception is a frequent cause of pediatric bowel obstruction.
- Early diagnosis of intussusception is vital to prevent severe complications.
- Established validity parameters for ultrasonography in pediatric intussusception diagnosis are needed.
Purpose of the Study:
- To determine the validity parameters of ultrasonography for diagnosing intussusception in children.
- To compare ultrasonography findings against surgical outcomes as the gold standard.
Main Methods:
- A cross-sectional validation study involving 127 children aged 3 months to 12 years.
- Ultrasound scans performed using a high-frequency (8.5 MHz) probe.
- Surgical findings served as the gold standard for comparison.
Main Results:
- Diagnostic accuracy of ultrasonography was 85.83%.
- Sensitivity: 82.93%, Specificity: 91.11%.
- Positive Predictive Value (PPV): 94.44%, Negative Predictive Value (NPV): 74.55%.
Conclusions:
- Ultrasonography is a valuable first-line diagnostic tool for pediatric intussusception.
- Early diagnosis via ultrasound facilitates prompt management.
- Utilizing ultrasound can significantly decrease the risk of complications associated with intussusception.
Background:
Intussusception is a common cause of bowel obstruction in children, and early diagnosis is crucial to prevent complications. Ultrasonography is widely used to diagnose intussusception, but its validity parameters in children have not been well-established. The objective of this study is to determine the validity parameters of ultrasonography in diagnosing intussusception in children, taking surgical findings as the gold standard.
Methods:
This cross-sectional validation study was conducted at the diagnostic radiology and surgery departments of Ayub Teaching Hospital, Abbottabad. This study duration spans from September 2022 to December 2023, and 127children of both sex with ages in the range of 3 months to 12 years suspected to have intussusception on ultrasound as per operational definition were included, and patients managed conservatively were excluded. Ultrasound scan was performed with Toshiba Xario-100 machine using high frequency 8.5 MHz probe. All data, including patients' demographics were recorded on a proforma. Data analysis was conducted using SPSS version 25.
Results:
The mean age of patients was 6.50±3.38 years. The diagnostic accuracy of ultrasonography was 85.83%, with sensitivity of 82.93%, specificity of 91.11%, positive predictive value (PPV) of 94.44%, and negative predictive value (NPV) of 74.55%.
Conclusions:
The use of ultrasonography as a first-line diagnostic tool for intussusception in children can help in early diagnosis and prompt management of the condition, which can significantly reduce the risk of complications.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
