Results of endoscopic radiofrequency ablation in patients with heterotopic gastric mucosa in the cervical esophagus

Introduction. Minimally invasive endoscopic treatment methods aimed at the destruction of heterotopic gastric mucosa in the cervical esophagus and relief of clinical symptoms are of priority importance.The purpose of the study. To study the effectiveness, compare the standard and modified radiofrequency ablation (RFA) protocol in symptomatic patients with heterotopic gastric mucosa in the cervical esophagus.Materials and methods of research. The results of endoscopic RFA were studied in 14 patients: 7 patients underwent RFA according to the protocol for the treatment of Barrett's esophagus, the rest of the patients - modified protocol of RFA.Treatment results. Eradication of heterotopic gastric mucosa in the cervical esophagus was achieved in 100 % of patients. The use of modified protocol of triple RFA exposure allowed to reduce the number of sessions required for eradication of gastric heterotopia in the cervical esophagus - 2.0 (2.0; 2.0) versus 1.0 (1.0; 1.5), p=0.035. Decreasing in the total score of RSI scale was revealed comparing the severity of laryngopharyngeal symptoms after RFA eradication of heterotopia after 8 months - 3.0 (1.75; 5.0) compared to the total score of RSI scale after conservative therapy - 16.5 (13.75; 22.5), p=0.001.Conclusion. Endoscopic RFA in patients with heterotopic gastric mucosa in the cervical esophagus demonstrate efficacy and safety.
