Bariatric endoscopic antral myotomy: a pilot study assessing technical feasibility, physiologic changes, and preliminary efficacy
Background and Aims
Gastric balloons and endoscopic sleeve gastroplasty appear to work by delaying gastric emptying. We hypothesized that pylorus-sparing antral myotomy would inhibit the antral pump, inducing gastric retention and similarly resulting in weight loss.
Methods
In this single-center pilot study, we assessed bariatric endoscopic antral myotomy (BEAM) using submucosal tunneling. The primary outcomes were feasibility, safety, and efficacy at 6 and 12 months, whereas the secondary outcomes were changes in the gastric-emptying rate and gastroparesis cardinal symptom index (GCSI) score.
Results
Six subjects underwent successful BEAM. One required needle decompression, and another developed pulmonary embolism, treated without sequela. At 6 and 12 months, patients achieved 9.1% ± 8.9% and 12.2% ± 7.1% total weight loss (P < .0005). The gastric-emptying rate was delayed by 36.6% in those with ≥10% total weight loss. The GCSI score increased significantly at 12 months, particularly regarding early satiety.
Conclusions
This pilot study suggests BEAM is feasible and appears to induce delayed gastric emptying that is associated with significant weight loss, without symptoms of gastroparesis.
