Pseudoachalasia is mimicking clinical and physiologic manifestations of idiopathic achalasia but results from alternative etiologies that infiltrate or obstruct the esophagogastric junction (EGJ). Anti-reflux surgery is one of the potential etiologies of pseudoachalasia. The majority of cases with persistent dysphagia after a tightly constructed Nissen fundoplication results from EGJ outlet obstruction (EGJOO) and in rare cases progresses to pseudoachalasia. In these extreme cases, endoscopic dilation is not a sufficient treatment and take down of fundoplication would be necessary. In this case report, we present a patient with long-standing GERD symptoms that underwent magnetic sphincter augmentation (MSA) with complete resolution of his reflux symptoms. He did not have dysphagia prior to surgery and his preoperative manometry showed normal peristaltic progression of esophageal contractions. He developed pseudoachalasia 14 months after surgery. Repeated endoscopic dilation in this case resulted in resolution of dysphagia and complete restoration of peristaltic contractions.
