Patients with post therapeutic stenosis after EMR (2.9% 8.9% (9/101) were diagnosed with oesophageal stenoses and an indication for dilation after ablation. In the respective groups, relevant stenosis developed in 3.7% (2/54) of cases in the H-APC arm and in 14.9% (7/47) of those in the RFA arm. All of the stenoses were treated effectively using endoscopic dilation. To exclude the possibility that RFA balloon treatment might increase the complication rate, a subgroup analysis was performed. None of the patients who were treated with a 360° RFA balloon developed stenoses.Patients were asked to record their pain levels by visual score from 1 to 10 and pain duration after discharge. This scores were recorded ad discharge and at follow-up endoscopy. Patients recorded higher pain levels after RFA, with a mean score of 4.56, than after H-APC, with a mean score of 2.07. The duration of pain was measured in days. Patients reported a longer period of pain after RFA, at 7.54 days, in comparison with H-APC, at 3.59 days.
