Long-term surgical outcomes of apple-peel atresia.

Purpose: The purpose of this study was to investigate (i) postoperative course of apple-peel atresia (APA), (ii) long-term follow-up of APA children, and (iii) risk factors for poor prognosis.
Methods: We conducted a retrospective review of 39 APA neonates treated at our institution between 2008 and 2017. Patient characteristics, operative details, postoperative course, long-term outcomes, and prognostic factors were analyzed.
Results: Of the 39 APA neonates, 30 (76.9%) were born preterm, and 20 (51.3%) were diagnosed prenatally. All patients underwent primary anastomosis within the first week after birth: 10 laparoscopic-assisted (25.6%) and 29 open (74.4%). Postoperative complications occurred in 28 patients (71.8%), of which 20 (71.4%) developed cholestasis. Survival at hospital discharge was 94.9%. Median parenteral nutrition period was 59 days. Reoperation was required in 7 children (17.9%) owing to anastomotic obstruction (n = 3) and adhesive intestinal obstruction (n = 4). 32 children (82.1%) were followed up for an average of 5.7 years, of which 23 children (71.9%) showed normal growth and development. APA patients with low birth weight and associated anomalies had significantly worse outcomes.
Conclusion: Most of the patients with apple-peel atresia have excellent long-term outcomes, though initial postoperative complications are common. Low birth weight and the presence of associated anomalies are independent prognostic factors in APA.
