COMPREHENSIVE RADIOLOGICAL DIAGNOSIS OF PAYRA'S DISEASE IN CHILDREN

Abstract

Payra’s disease, also known as left colonic syndrome, is a rare congenital or acquired condition characterized by functional obstruction at the splenic flexure due to fixation or angulation of the colon. This study aimed to evaluate the diagnostic value of complex radiological methods—fluoroscopy, multislice computed tomography (MSCT), and magnetic resonance imaging (MRI)—in children with chronic constipation and colonic dyskinesia. Eighty-six pediatric patients aged 3–16 years were examined using a standardized multimodal imaging protocol. Fluoroscopy identified delayed contrast transit in 67% of patients, MSCT revealed anatomical fixation and proximal dilation in 84%, while MRI confirmed motility disturbance in 71% without structural obstruction. The overall diagnostic accuracy reached 96%, with MSCT proving most effective for anatomical visualization and fluoroscopy for dynamic functional assessment. MRI contributed by ruling out neuromuscular and inflammatory pathologies. A strong correlation was noted between disease severity and patient age, with older children exhibiting more pronounced fixation and dilatation. The study concludes that the combination of fluoroscopy, MSCT, and MRI provides the highest diagnostic precision for pediatric Payra’s disease, ensuring early detection, optimal management, and prevention of unnecessary surgery.
