Tongue-like Barrett’s esophagus is associated with gastroesophageal reflux disease

Figure 5 The circumferential location of ESEM in subjects with the W, D, and T types of ESEM. Data are shown in terms of clock face orientation. The numbers represent the percentage of lesions on each side of the esophageal wall relative to the total number of lesions. The T-type ESEM is located mainly at the 12 and 1 o’clock wall (right anterior) of the lower esophagus, whereas the D and W types of ESEM are mainly located at the 9 to 12 o’clock wall (left anterior) of the lower esophagus. The circumferential distribution of ESEM differed significantly among subjects with different types of ESEM (χ² test: P < 0.05, T vs D, D vs W and W vs T).
