Risk factors for failure of hydrostatic reduction of intussusception in pediatric patients: A retrospective study

The aim of this current study was to explore the risk factors associated with failure of hydrostatic reduction of intussusception in pediatric patients.Patients with intussusception treated with hydrostatic reduction from January 2010 to December 2016 were retrospectively analyzed. Candidates for inclusion in the study were children from 0 to 18 who were diagnosed with intussusception and treated with hydrostatic reduction. We excluded the patients who had contraindications for hydrostatic reduction, which included peritonitis, perforation signs, and non-responsive shock that required surgery. The data collected included: demographic data (sex, age, and bodyweight), symptoms (vomiting, abdominal pain, rectal bleeding, diarrhea, distention, constipation, and duration of symptoms), signs (temperature, palpable mass, and location of the mass), and other investigations (white blood cell counts, neutrophils, electrolytes, and ultrasound findings).The risk factors for failure of hydrostatic reduction of intussusception were analyzed using the univariable analysis and the multivariable analysis. In the univariable model, the significant risk factors for failure of hydrostatic reduction of intussusception analyzed were age, bodyweight, duration of symptoms, rectal bleeding, constipation, palpable abdominal mass, poor prognosis signs on ultrasound scans and location of mass (the P value for each parameter are stated in ). After the multivariable analysis was done, we found that the significant risk factors for failure of hydrostatic reduction of intussusception were an age of under 1-year-old (OR = 3.915, P = .027), duration of symptoms more than or equal to 48 h (OR = 0.056, P
