Brief summary

The ARMA technique improves GORD-related quality of life with a low proportion of adverse effects.

Detailed description

Gastroesophageal reflux disease (GERD) is defined as the presence of symptoms or complications secondary to the passage of gastric contents into the esophagus, oral cavity or structures of the airway. The prevalence worldwide is between 8-33%. The clinical practice guidelines of the American College of Gastroenterology establish that first-line treatment, in the absence of alarm symptoms, should be carried out empirically. This treatment consists of hygienic-dietary measures and the use of proton pump inhibitors (PPIs) for 8-12 weeks. Despite the proven effectiveness of PPIs, there is 10-40% of patients who do not respond adequately to this treatment. All this has motivated the appearance of endoscopic and surgical techniques that offer an alternative to medical treatment. Among them is the technique of antireflux ablation of the cardiac mucosa (ARMA) in which the resection of the mucosa is replaced by an ablation with electrocoagulation current or by argon gas fulguration.

Design outcomes

Primary

MeasureTime frameDescription
To evaluate the clinical efficacy (measured through the GERD-HRQL questionnaire) of the ARMA technique for the endoscopic treatment of PPI-dependent GERD.The GERD-HRQL questionnaire score without PPI from visit 1 will be compared with the score without PPI from visit 4 (month 12).GERD-HRQL questionnaire score. Quantitative variable. Clinical success will be defined as a\> 50% reduction in symptom score. The scale has 11 items. Each item is scored from 0 to 5, with a higher score indicating a better QOL.

Secondary

MeasureTime frameDescription
GERD-Q questionnaire scoreThe GERD-Q questionnaire score without PPI from visit 1 will be compared with the score without PPI from visit 4 (month 12).The GERDQ questionnaire is diagnostic for gastroesophageal reflux disease. Clinical success will be defined as a\> 50% reduction in symptom score. The total Total score of 0 to 2 points = 0 % likelihood of GERD; 3 to 7 points = 50 %; 8 to 10 points = 79 %; 1 to 18 points = 89%;
PPI consumptionIt is measured in the different visits after the intervention (month 1, month 3 and month 12)Ordinal qualitative variable: The patient will indicate if he feels satisfied / neutral / dissatisfied.
pHmetry-impedancemetryThis test will be performed on the patient before the intervention, in month 3 and in month 12Technique used to quantify acid, know when there is more acid reflux and correlate symptoms with the presence of that acid. one of the measurements that we are going to obtain with this test is acid exposure time.
High resolution manometryThis test will be performed on the patient before the intervention, in month 3 and in month 12This technique measures the pressure of esophageal contractions and with this technique different measurements are obtained such as lower esophageal sphincter resting pressure, integrated relaxation pressure, ICD.
