Patterns of Esophageal Motility and Bolus Transit in Children With Repaired Esophageal Atresia

Esophageal dysmotility is common after esophageal atresia (EA) repair. Esophageal manometry (HRM) is the gold standard to investigate motility. We aim to characterize esophageal dysmotility and bolus transit for liquid and solids in children with repaired EA. Retrospective analysis of HRM from children with repaired EA. Five liquid and 5 solid swallows per child were assessed for the standard manometric measurement and peristalsis pattern. Impedance tracings were used to assess bolus transit. Ninety measurements were assessed from 9 patients, 44% Females. Mean age was 10.5 (±4.6) years. All children had dysphagia and anastomotic strictures were excluded. None of the children had intact peristalsis, 44.4% of the liquid swallows were failed, 33.3% fragmented and 22.2% ineffective. 44.4% of the solid swallows were failed, 44.4% fragmented and 11.1% ineffective. 33.3% had incomplete bolus transit in the whole esophagus, 44.4% in the upper and 11% in the lower esophagus. Mean peristalsis break for liquid was 7 cm (±2.1) and for solid was 5.9 cm (±3.2) P .025. Impaired esophageal motility is universal post EA repair. Failed and ineffective peristalsis predominate with incomplete bolus transit and large peristalsis breaks after liquid and solid swallows. HRM can provide clinical guidance, diagnostic and prognostic information post EA repair.
