Sequenzen:
![Sequence 1: patient presentation](https://www.endoscopy-campus.com/wp-content/uploads/2016/07/Kleines-Karzinom-im-Barrett-Oesophagus-EMR-und-RFA-Sequenz-1-wpcf_60x60.jpg)
A 46-year-old patient with short-segment Barrett’s esophagus that had been receiving monitoring since 2009, now presenting with a mucosal adenocarcinoma.
![Sequence 2: imaging of the Barrett’s segment without and with FICE](https://www.endoscopy-campus.com/wp-content/uploads/2016/07/Kleines-Karzinom-im-Barrett-Oesophagus-EMR-und-RFA-Sequenz-2-wpcf_60x60.jpg)
Endoscopic imaging of the short, tongue-shaped Barrett’s esophagus segment, and correlation with earlier findings before proton-pump inhibitor treatment. Above a small island of squamous epithelium at the 3-o’clock position, there is a tiny area above the esophagogastric mucosal junction from which a positive biopsy had been taken.

This area is imaged in detail, both in its unenhanced state and with Fujinon Intelligent Chromoendoscopy (FICE) technology, including magnification.
![Sequence 4: excision of the lesion using multiple-band ligation](https://www.endoscopy-campus.com/wp-content/uploads/2016/07/Kleines-Karzinom-im-Barrett-Oesophagus-EMR-und-RFA-Sequenz-4-wpcf_60x60.jpg)
Excision of the area around the small histologically positive mucosal island, using the Duette system with rubber-band ligation and loop excision.

The excision surface, with coagulated vessel stumps. Demonstration of the mounted resection specimen. Histology: mucosal adenocarcinoma extending to the resection margin laterally.
![Sequence 6: radiofrequency therapy for the residual Barrett’s](https://www.endoscopy-campus.com/wp-content/uploads/2016/07/Kleines-Karzinom-im-Barrett-Oesophagus-EMR-und-RFA-Sequenz-6-wpcf_60x60.jpg)
Resection of the residual short Barrett’s segment using radiofrequency ablation (RFA). Demonstration of the whole range of accessories, from circumferential balloon ablation to focal devices, along with a focal device (TTS) that is introduced through the endoscope’s working channel. The residual Barrett’s is removed with these devices.
