Abstract/OtherAbstract:
RESULTS: Esophageal manometry and pH monitoring were conducted for a mean duration of 91.5 min. Basal LES pressure averaged (+/-SD) 9.2+/-4.8 mmHg; in 4 of 10 patients (40%) the LES pressure was largely undetectable, varying between 0 and 2 mmHg. Mean LES pressure was inversely correlated with age (r=0.7, P=0.02). The total number of reflux episodes/h averaged 32.1+/-12.1 LES pressure reached 0 mmHg in 98% of reflux episodes. Type I LES relaxations were present in 3.15+/-1.1 reflux episodes/h, whereas type II LES relaxation occurred in 2.3+/-2.4 episodes/h. Acid reflux episodes appeared during absent basal LES tone periods, without phasic LES relaxations, in 74%.
CONCLUSIONS: Absent basal LES tone is the main mechanism of GER in a subgroup of NIC, especially in older children. Transient LES relaxation, the most common known event associated with acid reflux in neurologically normal children, seems to precede a minority of reflux events in NIC.
