Intragastric pressure in the patients with hypertrophic pyloric stenosis and normal children was measured using an open tip manometer with a 3-lumen tube. In the stomachs of 13 normal children, 1.79 peristaltic waves per minute with strength of 10.5 cmH_20 and duration of 10.5 seconds were observed. The pressure at the lower esophageal sphincter (LES) was 22.3 cmH_20. In 31 patients with hypertrophic pyloric stenosis, the peristaltic waves showed 21.7 cmH_2O in pressure and 21.1 seconds in duration. Its frequency was 1.11 contractions per minute. The LES pressure in the children with pyloric stenosis was 28.0 cmH_20. In one week after pyloromyotomy, the pressure of the peristaltic waves decreased to 8.4 cmH_20 with duration of 17.8 seconds, and frequency of 0.63 contractions per minute. All these values reduced from those before pyloromyotomy. The LES pressure also reduced to 21.8 cmH_20.
