The correct answer is  The symptoms and radiologic findings in this patient suggest achalasia. Evaluation includes endoscopy to rule out a stricture or cancer. Barium swallow will show a dilated esophagus, failure of the LES to relax during swallowing, and a lack of peristalsis. Nonoperative management is of limited usefulness but may be considered in high-risk patients who are not candidates for surgery.
