Ablation Treatments for Barrett’s Esophagus

DESCRIPTION

Barrett’s esophagus (BE) is a condition in which the normal squamous epithelium is replaced by specialized columnar-type epithelium, known as intestinal metaplasia. Intestinal metaplasia is a precursor to adenocarcinoma.

These metaplastic changes can be triggered by the inflammation and injury caused by chronic gastroesophageal reflux or chronic esophagitis and is associated with an increased risk of developing adenocarcinoma of the esophagus.  Barrett’s esophagus is confirmed by biopsy of the epithelium and microscopic identification of the metaplastic cells, and differentiated into low grade or high grade dysplasia.

Endoscopic resection and mucosal ablation have become the preferred treatment for most patients with Barrett’s esophagus and high grade dysplasia (with radiofrequency ablation traditionally being the first choice). The types of ablation procedures include:

The National Comprehensive Cancer Network recommends using RFA and cryoablation for residual or recurrent high grade or low grade dysplasia, further recommending that long-term palliation of dysphagia can be treated with endoscopic tumor ablation by Nd: YAG laser, PDT or cryoablation.

IMPORTANT REMINDERS

ADDITIONAL INFORMATION

For patients with non-dysplastic Barrett’s esophagus, it cannot be concluded that the benefit of RFA outweighs the risk, and therefore RFA is considered investigational. Data for the efficacy of cryoablation of BE with or without dysplasia are limited. The studies consist of small numbers of patients with short-term follow-up, and therefore, cryoablation of Barrett’s esophagus is considered investigational.
