Anti-Reflux Endoscopic TX Using APC (AREA) in GERD Patients: (The AREA Study)

Официальное название

Anti-Reflux Endoscopic Therapy Using Argon Plasma Coagulation (AREA) in Gastroesophageal Reflux Disease (GERD) Patients: A Single Center, Randomized, Sham, Controlled Trial (The AREA Study)

Обзор

This will be a randomized clinical trial examining the efficacy and safety of ARAT (intervention group) in patients with chronic GERD symptoms (typical symptoms of GERD, i.e. heartburn or acid reflux/regurgitation at least twice a week) for the last 6 months. Patients must have a positive pH test and a negative manometry (no treatment) procedure.

Вмешательства

• Процедура ARAT
  For patients randomized to ARAT intervention, the area of cardia, along greater curvature will be cleaned followed by demarcation of a 1-1.5 cm area of non-ablation zone with two vertical lines by use of Pulsed APC (30W, Effect 2) using the H-APC catheter. Next, the area of cardia, on either side will be injected in sequence using a methylene blue (0.5%) and normal saline (0.9%) using the H-APC catheter jet system (Effect 30-70). Next, the mucosa, starting below the z-line and up to 3 cm below w
• Процедура Sham intervention (control)
  Patients randomized to the control arm, will undergo a sham intervention. This will include performing upper endoscopy with procedural sedation followed by markings of landmarks as described. This will be followed by gastroscope retroflexion in the gastric cardia with at least 15 minute of examination time spent in retroflexion to reciprocate the H-APC intervention. No H-APC or submucosal injection or other intervention will be performed during the upper endoscopy with sham intervention. All Pat
