The role of distance between upper and lower esophageal pouches to predict the possibility of delayed repair in children with isolated esophageal atresia.

Abstract

A retrospective study was performed to evaluate the role of distance between upper and lower esophageal pouches and pouch lengths to predict delayed primary repair (DPR) in patients with isolated esophageal atresia (EA). Patients with isolated EA were evaluated for demographic features, associated anomalies, surgical options, and complications. The babygrams obtained for evaluating gap assessment were examined for the distance between pouches and pouch lengths. Patients were divided into two groups: DPR and esophageal replacement (ER). Fourteen cases with a mean age of 4.1 ± 1.9years (1-9years) were included. Female to male ratio was 6:8. There was no significant difference between DPR and ER groups for pouch lengths. The median distance between two pouches were significantly higher in ER group [50mm (29.4-83.6) vs 18.8mm (3.4-34.5) (p < 0.05)]. The distance between two pouches and pouch lengths were similar in patients with and without anastomotic strictures (p > 0.05). Both upper and lower pouch lengths were shorter in ER group compared to DPR group. However, pouch lengths cannot be considered as a single criterion to predict the need for ER. Large cohort of patients are needed to define the cut-off values for shortest pouch length to achieve a DPR.
