Esophageal achalasia is the best described primary esophageal motility disorder. Endoscopic ultrasound (EUS) is considered a useful adjunct for grading and establishing the prognosis of these patients. Recent experience using Da Vinci robotic assisted myotomy has demonstrated that this is a safe and effective approach of treatment. The benefit of magnification and three dimensional imaging helps prevent esophageal perforation and identify residual circular muscle fibers. This paper reports the relative efficacy and safety of intraoperative ultrasound during robotic assisted myotomy in a patient with severe achalasia. Intraoperative esophageal endoscopic ultrasound is a safe technique that may improve the success rate of surgery by confirming the adequacy of myotomy, thereby decreasing the likelihood of recurrent symptoms.
