Developing a Nomogram for Predicting Surgical Intervention in Pediatric Intussusception After Pneumatic Reduction: A...

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Medical Imaging

Background:

• Intussusception is a common surgical emergency in children.
• Pneumatic reduction is a primary treatment, but recurrence and failure necessitate further intervention.
• Predictive tools are needed to guide management decisions after initial reduction attempts.

Purpose of the Study:

• To develop and validate a nomogram for predicting surgical intervention in pediatric intussusception post-pneumatic reduction.
• To identify key clinical predictors of failed pneumatic reduction requiring surgery.

Main Methods:

• Retrospective analysis of 1041 pediatric intussusception cases from four Chinese hospitals (2019-2022).
• Patients divided into successful (control) and failed (operation) pneumatic reduction groups.
• Logistic regression used to build a predictive model, with data split into training (70%) and validation (30%) sets.

Main Results:

• A nomogram was constructed based on five independent predictors: age, duration of abdominal pain, hematochezia, C-reactive protein levels, and ultrasound-indicated intussusception position.
• The nomogram effectively predicted the failure of pneumatic reduction, indicating the need for surgical intervention.

Conclusions:

• A validated nomogram can accurately predict the likelihood of surgical intervention in pediatric intussusception after pneumatic reduction.
• The nomogram incorporates readily available clinical and imaging data, making it a practical tool for risk stratification.
• This tool assists clinicians in identifying high-risk patients who may require prompt surgical management.
