Pressure topography and impedance of manometry plots of patients with and without transition zone (TZ) defects. a Oesophageal pressure topography plot of a patient without a transition zone (TZ) defect: the bolus was transited completely. b The impedance manometry plot of a patient without a transition zone (TZ) defect: complete bolus transited. c Oesophageal pressure topography plot of a patient with a transition zone (TZ) defect, incomplete bolus was not transited. d The impedance manometry plot of a patient with a transition zone (TZ) defect, the bolus was not transited completely
