BACKGROUND: Gastroesophageal reflux (GER) is frequently observed in children treated for congenital diaphragmatic hernia (CDH) at birth, as well as esophageal dysmotility, that has been hypothesized to be caused by innervatory anomalies. The aim of this study is to evaluate GER and dysmotility in young patients with CDH using pH-multichannel intraluminal impedance. METHODS: Thirty children (17 boys and 13 girls) who underwent repair for CDH between 2002 and 2007 with a median age of 5.2 years (range, 3-10 years) were included in the study. All patients were operated on with a subcostal laparotomy incision and had a left-sided diaphragmatic defect. The defect repair required an artificial patch (Goretex, Gore Medical, Flagstaff, AZ) in 8 patients (27%) because of its size. We described impedance reflux parameters and some specific motility parameters studied on 10 standardized swallows. RESULTS: The incidence of GER was 86%. Reflux was mainly nonacidic, postprandial, and short-term and reached only the distal esophagus. Esophageal dysmotility was observed only in the distal esophagus. CONCLUSIONS: With the use of pH-multichannel intraluminal impedance, both GER and esophageal motility in patients with congenital malformations can be analyzed. In patients with CDH, impaired motility seems to involve only the distal esophagus. In this group, the specific pattern of reflux is probably caused by the involvement of gastroesophageal junction, without significant intrinsic innervation abnormalities as observed in patients with esophageal atresia.
