Approach

The goal of treatment of Barrett's oesophagus is to reduce reflux of gastric acid into the oesophagus and eliminate the Barrett's epithelium..

Non-dysplastic Barrett's oesophagus

  • Treatment with proton-pump inhibitors (PPIs) and surveillance: use of PPIs is associated with a decreased risk of progression to high grade Barrett's oesophagus or oesophageal carcinoma.[7] Although most drugs are designed to be administered once daily, treatment may be increased to twice daily in order to avoid periods when the hydrogen ion concentration can reduce the intraluminal pH to below 4. However, the American College of Gastroenterology guidelines state that increasing the frequency to twice daily dosing should be balanced with the increased risk of potential harm with long-term therapy.[7] One phase 3 open-label trial reported a small but significant reduction in all-cause mortality in patients with Barrett's oesophagus treated with high-dose esomeprazole, compared with low-dose esomeprazole, after 8.9 years of treatment.[48]

  • Anti-reflux surgery: although anti-reflux surgery, such as Nissen fundoplication may be effective at reducing gastro-oesophageal reflux symptoms, guidelines recommend against the use of anti-reflux surgery to reduce the risk of progression of Barrett's oesophagus to adenocarcinoma.[7][33]​ These recommendations are based on the risks and potential complications associated with the minimally invasive surgery, as well as the lack of sufficient evidence documenting a lower risk of progression to neoplasia in this patient group. Anti-reflux surgery may be considered for treatment of reflux symptoms in people with Barrett's oesophagus who have a poor or incomplete symptomatic response to PPIs.[1]

The American Gastroenterological Association (AGA) suggests not using endoscopic eradication therapy on a routine basis in patients with non-dysplastic Barrett's oesophagus.[49]

Surveillance is recommended every 5 years for non-dysplastic Barrett's oesophagus <3 cm long, and every 3 years for non-dysplastic Barrett's oesophagus ≥3 cm long.[7]

Guidelines recommend against routine use of endoscopic therapies such as radiofrequency ablation (RFA) for the eradication of non-dysplastic Barrett's oesophagus, because of the low risk of progression to dysplasia and adenocarcinoma.[1][7]​​[32]​​

Barrett's oesophagus with low-grade dysplasia

Dysplasia is an important predictor of cancer risk in Barrett's oesophagus but there is considerable inter-observer variability on its interpretation. The diagnosis of any degree of dysplasia (or indefinite for dysplasia) requires confirmation by an experienced gastrointestinal pathologist.

Patients with Barrett's oesophagus with low grade dysplasia may be managed with surveillance or endoscopic eradication therapy.[7][32]​​[50]​ Discuss the risks and benefits of surveillance versus endoscopic eradication therapy with patients who have low grade dysplasia.[7]​ The AGA suggests endoscopic eradication therapy over surveillance in this patient group.[49]

​Any visible lesions should be removed used endoscopic resection techniques and sent for histopathological examination before performing RFA.[7][32]​​​ RFA is the preferred ablative technique.[32][49]​​[51]​​​​​​ The aim of RFA is complete eradication of intestinal metaplasia.[7]​ The National Institute for Health and Care Excellence (NICE) in the UK recommends offering RFA to patients with low-grade oesophageal dysplasia diagnosed from biopsies taken at two separate endoscopies. Two gastrointestinal pathologists should confirm the histological diagnosis.[33]

One randomised trial demonstrated that ablation of low-grade dysplasia reduces the incidence of progression to adenocarcinoma.[52] Adverse events associated with RFA include oesophageal stricture formation and post procedure pain. Bleeding and oesophageal perforation are rare.[53]

Patients require regular surveillance after treatment; surveillance intervals are dictated by pre-treatment histology.[7]

Barrett's oesophagus with high-grade dysplasia

The finding of high-grade dysplasia is associated with a 20% to 40% risk of harbouring adenocarcinoma.[1][54]​ If high-grade dysplasia is confirmed, endoscopic eradication therapy is recommended over surveillance.[7][49]​ NICE in the UK recommends endoscopic resection of visible oesophageal lesions for the first-line treatment of patients with high-grade dysplasia.[33]

Visible lesions should be resected and all remaining Barrett's epithelium eradicated.[1][7][32]​​

Endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) should be used to resect visible lesions.[1][7]​​[32]​​[49]​ Resected lesions should undergo histologic analysis. EMR is an effective treatment for nodular high-grade dysplasia as it achieves complete resection of the dysplastic area with negative margins.[55] ESD is a highly effective technique that provides specimens with wider lateral margins and increased depth, but it is only available at specialised centers.

NICE in the UK recommends offering endoscopic ablation to remove any residual Barrett's oesophagus in patients with high-grade dysplasia after treatment with endoscopic resection.[33]​ After EMR or ESD, RFA is the preferred ablative technique to eradicate remaining Barrett's epithelium.[7][49]​ The efficacy and safety of RFA is supported by robust data, including results from one multi-centre, sham-controlled, randomised clinical trial demonstrating complete eradication of the dysplastic epithelium in 81% of patients treated with this technique.[56] Adverse events of RFA with or without EMR are: oesophageal stricture (5.6%), bleeding (1%) and oesophageal perforation (0.6%).[53]

Patients require regular surveillance after treatment; surveillance intervals are dictated by pre-treatment histology.[7]

Oesophagectomy is a definitive treatment option, which enables identification of any occult malignancy.[57] However, this intervention is associated with significant procedure-related mortality and long-term morbidity.[58]
