Introduction and importance: Neonatal jejunal atresia repair is a critical surgery, but late complications such as megaduodenum can occur, emphasizing the need for continued follow-up and management. Case presentation: We present a 13-year-old female with a history of neonatal jejunal atresia, repaired 13 years ago by side-to-side jejunojejunal anastomosis. Due to family circumstances, she was lost to follow-up and did not receive further care. Thirteen years after the primary surgery, she presented with chronic, non-specific symptoms of abdominal distension, vomiting, and malnutrition, leading to the diagnosis of megaduodenum. Clinical discussion: The patient underwent duodenal resection and end-to-end duodenojejunal anastomosis. One year following the surgery, her symptoms completely resolved, and she showed significant nutritional recovery. Conclusion: This case highlights the importance of timely surgical intervention and long-term follow-up, demonstrating that anatomical reconstruction can be highly effective in treating pediatric megaduodenum, even when delayed by family-related factors.
