Abstract

Objective: Pediatric intestinal pseudo-obstruction (PIPO) is a rare, severe, and heterogeneous gastrointestinal motility disorder associated with intestinal failure, recurrent hospitalizations, and significant morbidity and mortality. This study aimed to evaluate the clinical features, management strategies, and long-term outcomes of children diagnosed with PIPO at a tertiary referral center. Methods: This retrospective single-center study included pediatric patients diagnosed with PIPO between 2011 and 2025. Diagnosis was established according to ESPGHAN consensus criteria. Demographic characteristics, clinical presentation, genetic findings, nutritional support, surgical interventions, intestinal transplantation, and long-term outcomes were retrospectively reviewed. Results: A total of 32 patients with PIPO were included, of whom 56.2% were female and 43.7% had early-onset disease. Genetic testing was performed in 22 of 32 patients; clinically significant variants were identified in 16 (50% of the total cohort), most commonly ACTG2 mutations. Prior abdominal surgery before referral was present in 84.3% of patients. During follow-up, 56% remained parenteral nutrition dependent, five patients underwent intestinal transplantation, and the overall mortality rate was 21.8%. Conclusions: PIPO is a highly heterogeneous disorder associated with substantial morbidity, prolonged nutritional support requirements, repeated surgical interventions, and significant mortality. Early diagnosis, genetic evaluation, multidisciplinary management, and timely referral to specialized intestinal failure and transplantation centres are likely to support more individualised management and may help prevent avoidable complications in affected children.
