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

Figure 3 Mechanical stimulation evoking moderate pain in patients with Barrett’s esophagus and healthy volunteers. Patients were hyposensitive to mechanical stimulation 4 cm above the esophago-gastric junction compared to healthy volunteers, P = 0.02. On the visual analogue scale, 1 = the sensation threshold, 3 = vague perception of moderate sensation, 5 = the pain threshold, and 7 = moderate pain. ^aP < 0.05.
