High-resolution esophageal pressure topography focusing on UES during 5-mL water swallow. (A) UES profile in patient with symptomatic CP bar demonstrating short sphincter relaxation and elevated intrabolus pressure within and proximal to UES. (B) Pressure topography study of same patient after esophageal dilation. Although still abnormal, there is an obvious improvement in UES opening, resulting in reduction of hypopharyngeal intrabolus pressure.
