Mechanism underlying the occurrence of Gastroesophageal reflux disease (GERD) in neurologically impaired children (NIC) is poorly understood. We sought to characterize, by Esophageal High Resolution Manometry (EHRM), alterations of esophageal motility associated with GERD in NIC and to compare with a group with a suspicion of GERD and normal psychomotor development (NDP). EHRM and multichannel intraluminal impedance/pH-metry (MII/pH) were conducted in 7 NIC and 9 patients with suspicion of GERD and NPD. Esophagogastric junction relaxation (EGJr), the presence/pressure troughs of the oesophageal segments, the distal contractile integral adjusted for esophageal length (DCIa) and the pressurization frontal velocity (PFV) were analyzed by EHRM. Three out of 7 NIC (42.8%) and 4 out of 9 patients with NPD (44.4%) resulted positive to MII/pH (p?=?1). No statistical differences were observed for EGJr and PFV between NIC and NPD patients. DCIa was significantly lower in NIC subjects respect to NPD patients (p?
