Effect of Esophageal Endoscopic Submucosal Dissection on Motility and Symptoms: A Prospective Study

Figure 5

Representative case from group A in which no change was found after endoscopic submucosal dissection (ESD). Patient number 11 is a typical case from group A (less than 2/3 circumferential resection). Symptom score and distal contractile index (DCI) were not increased after ESD. Red arrows indicate physiological contractions: the first, second, and third pressure trough, respectively.
