All 17 patients underwent 41 balloon dilation procedures, with each patient undergoing one to seven procedures (mean, procedures). The technical success rate was 100%, and clinical success was achieved in % (11/17) of the patients. Five patients (%) showed no recurrence of dysphagia after one session of balloon dilation. Of 12 patients (%) with recurrence of dysphagia, 10 underwent repeat balloon dilation and two underwent gastrostomy after the first session of balloon dilation. The maximum balloon diameters were 15 mm (n = 22), 20 mm (n = 16), and 25 mm (n = 3). As minor complications, three cases of type 1 esophageal rupture occurred in two patients (%).
