Abstract

Secondary achalasia may result from diseases that either infiltrate or compress the lower esophageal sphincter to create an increased high-pressure zone and subsequent esophageal body changes. With bariatric surgery, a potential high-pressure zone is created by a sleeve, band, or bypass just distal to the esophagus. We report four patients who years after a bariatric procedure developed dysphagia followed by esophageal body radiographic and/or manometric features of achalasia. In addition, each of these patients responded symptomatically to endoscopic or surgical therapy either which lowered this high-pressure zone. Furthermore, review of prior cases in the literature suggests this has occurred before. Physicians should be aware of this association but further study is needed on its true prevalence.
