Its diagnosis is challenging due to overlapping features with postoperative ileus, electrolyte disturbances, and other factors affecting the return of normal peristalsis. Delayed recognition can lead to bowel ischemia and increased morbidity. In this case series, four cases of PI were identified among 13,742 abdominal surgical procedures performed during the last 5 years (incidence: 0.029%). All patients were male, aged 7 months to 3 years. Three cases occurred following left nephroureterectomy with lymph node sampling for Wilms’ tumor, and one followed repair of a left-sided congenital diaphragmatic hernia. All children became symptomatic between postoperative days 6 and 7, presenting with bilious vomiting, abdominal pain/ distension, and inconsolable crying—symptoms that emerged after oral feeding had commenced. Ultrasound confirmed the diagnosis in all cases, demonstrating the characteristic bowel-withinbowel appearance. Two cases with ileo-ileal intussusception underwent immediate operative manual reduction. Two cases with ileo-colic intussusception had unsuccessful ultrasound-guided hydrostatic reduction followed by successful operative reduction. All reduced bowel segments appeared viable without identifiable lead points. All patients recovered uneventfully, though the first postoperative chemotherapy dose was delayed in the three Wilms’ tumor patients. therefore, PI should be considered in any child presenting with bilious vomiting and abdominal symptoms toward the end of the first postoperative week, particularly following retroperitoneal surgery. Early ultrasound examination and prompt surgical intervention, when indicated, are essential to minimize morbidity. A high index of suspicion remains the cornerstone of timely diagnosis.EnglishIntussusception, postoperative complications, Wilms’ tumor, congenital diaphragmatichernia, childhttps://www.yemenjmed.com/admin/abstract?id=420References1619
