NCT04065516

Brief Summary

The peroral endoscopic myotomy for the treatment of achalasia is associated with a higher incidence of gastroesophageal reflux disease compared with Heller's myotomy. Remodeling of the esophagogastric junction with hybrid argon plasma could decrease the passage of gastric or gastroduodenal content into the esophagus.

Outcome Measures

Primary Outcomes (3)

  • A change in erosive esophagitis grade assessed by upper endoscopy after ARAT

    Upper endoscopy is going to be used to measure the erosive esophagitis grade using the Los Angeles Esophagitis scale(grade A=mild, Grade B=moderate, Grade C=moderate high and Grade D=severe) after after ARAT

    measures will be performed at 3,6 and 12 months after ARAT

  • A change in esophageal acid exposure assessed by pHmetry study after ARAT

    A 24-hours pHmetry study is going to be used to measure esophageal acid exposure in esophagus after ARAT. DeMeester Score and the percentage of esophagic acid exposure will be used to assess pathologic reflux (\>14.73 and \> 6%, respectively)

    measures will be performed at 3,6 and 12 months after ARAT

  • A change in clinical symptoms of reflux disease assessed with a gastroesophageal reflux questionnaire after ARAT

    The clinical evaluation of reflux disease is going to be assessed by the use of a clinical gastroesophageal reflux disease questionnaire (GERD-Q) after ARAT. Reflux disease was considered positive when \>4 points is observed

    measures will be performed at 3,6 and 12 months after ARAT

Study Arms (1)

Argon Plasma Coagulation of the gastroesophageal junction

EXPERIMENTAL

Participants with abnormal acid exposure after peroral endoscopic myotomy for achalasia, will be treated by ablation of the gastroesophageal junction with hybrid argon plasma coagulation

Procedure: ARAT technique

Interventions

After an initial endoscopic evaluation, ARAT technique will be performed with marking, submucosal elevation at esophagogastric junction and then ablation with 100-120w of 270-300 degrees at esophagogastric junction, once the application of the therapy is performed mucosal lavage and immersion technique will be made to corroborate integrity and continuity of the gastrointestinal tract and rule out immediate complications.

Model Details: A clinical trial will be carried out, including all patients with achalasia, treated by peroral myotomy older than 18 years old, with abnormal acid exposure in the pHmetry test 3 months or more after treatment, who accept the management of ablation with hybrid argon plasma. To whom the ablation will be performed with Hybrid Argon Plasma and its effectiveness will be evaluated by clinical questionnaires, endoscopy and pH measurement at the beginning, 2 months, 6 months and 12 months after the procedure.
