Antireflux Mucosectomy Band (ARM-b) in Treatment of Refractory Gastroesophageal Reflux Disease After Bariatric Surgery

Laparoscopic sleeve gastrectomy has become the most commonly used bariatric surgery worldwide. However, there are a proportion of patients who present with a refractory GERD after this procedure. In these patients, when surgical conversion to RYGPB is not possible or declined, we propose to describe the results of an endoscopic antireflux mucosectomy band (ARM-b) technique in 6 LSG patients with refractory GERD. The technical feasibility was 100%; 5 out of 6 patients had a clinical response with a reduction of the GERD-HRQL score of > 50%. Two patients had adverse events: one esophageal stricture and one benign bleeding. ARM-b is feasible and potentially effective to treat patients with refractory GERD after LSG.
