Core Tip
Core Tip: There is limited data on performance of per-oral endoscopic myotomy (POEM) in patients with altered upper gastrointestinal anatomy, especially after bariatric surgery. To our knowledge, performance and outcomes of POEM have not been reported after sleeve gastrectomy, which is the most common surgical bariatric procedure. Given the worldwide epidemic of obesity, gastroenterologists may be increasingly faced with achalasia after bariatric surgery, for which POEM may be a viable endoscopic option. Our results show that POEM can be safely performed for achalasia in the setting of prior bariatric surgery and offers a safe and effective treatment for these patients with limited surgical options.
