• Dr. Jacques Bergman from the Academic Medical Center in Amsterdam, Netherlands performs a radio frequency ablation of Barrett's esophagus.

Professor Horst Neuhaus, who is director of gastroenterology and endoscopy at the Evangelisches Krankenhaus in Düsseldorf, Germany, has an annual live course which draws over 1000 registrants. In the video taken during the course, Dr. Jacques Bergman from the Academic Medical Center in Amsterdam, Netherlands is performing a radio frequency ablation of Barrett's esophagus. This patient had a prior endoscopic submucosal dissection of a superficial mucosal esophageal carcinoma originating in the Barrett-lined segment. This procedure is intended to destroy the residual non-neoplastic Barrett's mucosa. Assisting Dr. Bergman is Dr. Schultz from Berlin

This HALO 360 device is a bipolar probe which contains multiple electrical wires in alternating sequence on an expandable balloon. The size of the balloon is an important factor in this ablation technique and is determined by use of a sizing balloon. The correct position of the HALO 360 is monitored by passing an endoscope just above the balloon. The preprogrammed electrical discharge lasts for 1-2 seconds following which the balloon on the HALO 360 deflates. The white necrotic slough which remains on the wall is scraped off with a hood on the tip of the endoscope, and following this manoeuvre, a second application of the HALO 360 is made.

This technique has been replacing photodynamic therapy for ablation of Barrett's esophagus.

This procedure was performed at the Evangelisches Krankenhaus in Düsseldorf, Germany.
