Description of Medical ServiceBarrett's oesophagus is a metaplastic change of the lining of the oesophagus, such that the normal squamous epithelium is replaced by specialised or intestinalised columnar epithelium.
The disorder seems to be a complication of chronic gastrooesophageal reflux disease, although asymptomatic individuals might also be affected, and it is a risk factor for the development of oesophageal adenocarcinoma, a cancer with rapidly increasing incidence in developed societies.
An appropriately sized radiofrequency (RF) ablation catheter is selected and introduced over a guidewire in a side-by-side manner with an endoscope. The catheter’s balloon is then inflated and energy applied, circumferentially ablating the epithelium to a depth of less than 1 mm. The catheter is then removed and cleaned, and reintroduced if necessary. The clinician removes the ablated epithelium using irrigation and suction using the endoscope.
