Synopsis
Identify superficial upper-GI neoplasia suitable for organ-preserving endoscopic resection, obtain en-bloc pathology, and escalate non-curative histology to surgery or oncological treatment.
- Endoscopic treatment is appropriate only when invasion and nodal risk are sufficiently low for local excision to provide oncological cure.
- Enhanced imaging defines lesion borders and morphology; biopsies establish neoplasia but repeated sampling can create fibrosis that complicates definitive resection.
- En-bloc resection is preferred when feasible because orientation and margins determine curative status.
Key red flags
A visible Barrett lesion is resected for staging before ablation of the remaining flat metaplastic field.
Submucosal invasion, lymphovascular invasion, poor differentiation or involved deep margin raises nodal or residual-disease risk and can make endoscopic treatment non-curative.
Deep invasion, lymphovascular spread or a positive vertical margin makes local therapy potentially non-curative.
Reasoning priorities
Define lesion margins, morphology and synchronous disease.
Use the pattern to select EMR, ESD, surgery or further staging rather than ablating an uncharacterised nodule.
Worked reasoning
A 59-year-old with a long Barrett segment has a 14 mm raised nodule containing high-grade dysplasia on one targeted biopsy; expert imaging shows no second visible lesion.
- At an expert session, enhanced imaging defines the nodule and excludes a second visible lesion; the endoscopist chooses en-bloc endoscopic mucosal resection before any field ablation.
- The oriented specimen shows intramucosal T1a adenocarcinoma, well differentiated, with clear lateral and deep margins and no lymphovascular invasion, meeting the MDT’s local-curative criteria.
- The specialist service ablates the residual flat Barrett epithelium in staged treatment, preserving the resection result as the basis for avoiding oesophagectomy.
- Verify eradication at protocolled follow-up: biopsies show no residual dysplasia, the resection site is healed and the patient has no treatment-related stricture symptoms.
