Proximal and distal esophageal sensitivity is decreased in patients with Barrett’s esophagus

Figure 4 Response to heat stimulation in patients with Barrett’s esophagus compared to healthy volunteers. Patients were hyposensitive to heat stimulation 4 cm above the esophago-gastric junction (P = 0.04). On the visual analogue scale, 1 = the sensation threshold, 3 = vague perception of moderate sensation, 5 = the pain threshold. ^aP < 0.05.
