    Author: Valdovinos Díaz MA, Flores C, Facha MT, Koller Lucio J.

    Abstract:
    BACKGROUND DATA: Hipotensive lower esophageal sphincter (HLES) has been considered the most frequent finding in patients with gastroesophageal reflux disease (GERD). Recently it has been published that esophageal dismotility (ED) has a higher prevalence in GERD. OBJECTIVE: To compare the prevalence of HLES with ED in patients with GERD. MATERIAL AND METHODS: Consecutive patients with endoscopic esophagitis grade II or higher and abnormal esophageal acid exposure time in pH-monitoring were evaluated. Stationary esophageal manometry were performed in all patients. HLES was defined by: a) LES pressure < 10 mmHg, b) LES length < 2 cm and c) LES abdominal segment < 1 cm. ED was defined by: a) presence of more than 30% of peristaltic waves with an amplitude < 30 mmHg or b) more than 10% of simultaneous waves in distal esophagus. RESULTS: Thirty-seven patients, 27 women and 10 men were evaluated. Twelve patients (32.4%) had ED, 5 (13.5%) showed HLES. Four of these 17 patients had both abnormalities. Fifteen patients (40.5%) had normal findings and in 5 (13.5%) a high LES pressure was found. CONCLUSIONS: Esophageal dismotility is the most common manometric abnormality in patients with GERD.
