Long-term surgical outcomes of apple-peel atresia

Abstract

PurposeThe 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. MethodsWe 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. ResultsOf 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. ConclusionMost 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. Type of studyPrognosis study (case series). Level of evidenceLevel IV.
