Gastrointestinal symptoms related to antireflux surgery are result of either an incompetent gastroesophageal valve, a supra-therapeutic valve or other complications of anti-reflux surgery such as decreased gastric accommodation, rapid gastric emptying, gastroparesis, paraesophageal hernia, or exacerbation of another undiagnosed motility disorder. Here, we reviewed a diagnostic approach for these symptoms which starts with detailed history and a tailored approach in use of diagnostic tests and empirical treatment to aid in diagnosis. In treatment for these symptoms, a conservative approach with lifestyle modifications should be employed first and repeat surgical procedure should be reserved as the last option. Of the emerging endoscopic therapies for symptoms refractory to medical therapy, gastric per-oral endoscopic myotomy is effective in improving gastric emptying and related symptoms.
