Summary

Background Barrett's esophagus (BE) is defined by AGA as "a change in the esophageal epithelium of any length that can be recognized at upper endoscopy and is confirmed to have intestinal metaplasia by biopsy". It is a pre-malignant condition and may progress to low grade dysplasia, high grade dysplasia and ultimately esophageal adenocarcinoma which has poor prognosis with a 5-year survival rate of only 5-20%.Radiofrequency ablation (RFA) is a standard modality and well-studied endoscopic treatment for dysplastic BE. While the rate of complete eradication of dysplasia has been reported to be between 78% - 94% with RFA, the rate of complications associated with this procedure has been reported to be as high as 19.1%, and the costs are high. In a randomized clinical trial in patients with BE and low-grade dysplasia by Phoa et al in 2014, 68 patients underwent radiofrequency ablation therapy with a median of three ablation sessions per patient while 68 patients were randomized to endoscopic surveillance. In this study, a total of 13 patients (19.1%) experienced an adverse event in the treatment group versus no adverse events in the control group. Eight patients (11.8%) developed esophageal strictures which required a median of one dilation, three patients were noted to have small mucosal lacerations, one patient developed retrosternal pain treated with analgesics while one patient developed abdominal pain requiring hospitalization and treatment with analgesia. Several other studies have reported the rate of complications ranging between 5% to 19.1% and stricture formation being the most common among them. Hybrid argon plasma coagulation (H-APC) is a newer technique that involves submucosal fluid injection prior to performing APC. The injection of solutions (e.g., 0.9% sodium chloride solution (normal sterile saline) with or without supplementation of epinephrine, methylcellulose solution, hydroxyethyl starch, hyaluronic acid, autologous blood or blood substitute fluids) into the submucosa to limit the depth of thermal injury has been established both in pre-clinical studies for different tissues of the gastrointestinal tract and in the clinical practice for EMR and ESD, respectively.
