Fully Coated, Removable, Self-expanding Oesophageal Stents for Preventing Strictures Following Complete Barretts Excision.

Fully, Coated, Removable, Self-expanding Oesophageal Stents for the Prevention of Oesophageal Stricture Following Endoscopic Mucosal Resection of Short Segment Barrett's With High Grade Dysplasia and Early Cancer.

The purpose of this study is to investigate whether preventative placement of a removable oesophageal stent reduces the rate of scar tissue, or stricture formation after removing the precancerous or early cancerous Barrett's mucosa by Endoscopic Mucosal Resection (EMR). The stent will be placed 10-14 days after initial EMR. The stent will then be removed 8 weeks later by repeat Endoscopy. Patients will be followed up weekly following insertion of the oesophageal stent.

Inclusion Criteria:

• Patients with short segment Barrett's Oesophagus with high grade dysplasia or early cancer, having circumferential EMR to achieve complete Barrett's excision.
• Aged 18-75 years old
• Biopsy proven to be Barretts with HGD or EAC
• The absence or lymph node involvement
• Short segment <3cm of Barretts Oesophagus.

Exclusion Criteria:

• Women who are pregnant and the human foetus
• Children and/or young people <18 years
• People with an intellectual or mental impairment.
