Assessment of Esophageal High-Resolution Impedance Manometry in Patients with Nonobstructive Dysphagia

Figure 3

HRIM manifestation of peristalsis and incomplete esophageal transit (ICET). (a) One patient with EGJ outflow obstruction showed a 4.3 cm break in the 30 mmHg isobaric contour and exhibited ICET. (b) One patient of hiatal hernia had a 5.5 cm break in the 30 mmHg isobaric contour and presented ICET. (c) One patient of hypercontractile esophagus (presented hypercontractility of LES) showed a 7.4 cm break in the 30 mmHg isobaric contour and exhibited ICET. (d) One patient of distal esophagus spasm showed 4.8 and 3.7 cm breaks, respectively, and presented ICET.
