- Identify the 4 root causes of ablation failure in Barrett's esophagus
- Apply acid suppression optimization strategies to improve EET outcomes
- Select appropriate rescue strategies for refractory Barrett's esophagus
- Determine when endoscopic therapy is inadequate and surgery should be considered

4 root causes
When a patient with Barrett's esophagus fails multiple endoscopic eradication therapy (EET) sessions, the clinician must systematically evaluate the root cause before determining next steps. There are 4 major categories of ablation failure.
Wrong Patient
Patient selected for ablation who was never an appropriate candidate — too advanced disease (T1b+), lesion not amenable to endoscopic Rx, or poor surgical risk with advanced EAC.
Inadequate Acid Suppression
Most common cause. BE patients are less sensitive to acid, so symptoms cannot guide dosing. Standard PPI dosing often leaves abnormal esophageal acid exposure. Healing cannot occur in an acid environment.
Suboptimal Technique
Inadequate contact between ablation device and tissue, missed islands of BE, insufficient overlap, incorrect energy delivery, or failure to treat all visible Barrett's including the cardia and tongues.
Refractory Tissue
True biologic refractoriness — tissue with greater DNA aberration (aneuploidy, tumor suppressor gene deletions) that is inherently more resistant to ablation. However, ablation still succeeds more often than not even here.
First Step When Ablation Fails
Always ask: Am I trying to ablate cancer? Re-biopsy after 3 attempts at EET is warranted. Appearance of any new nodularity should raise concern for progression and warrants immediate EMR for staging.
Systematic Approach to Refractory Barrett's:
Rule out cancer — re-biopsy / re-stage any nodularity with EMR
Optimize acid suppression — switch to BID PPI, check pH-impedance
Review technique — did you treat all BE? Was contact adequate?
Consider alternative ablation modality (cryotherapy if RFA failing)
Consider rescue EMR for focal residual disease
Evaluate for fundoplication if reflux uncontrolled despite max PPI
Surgery — reserved for selected cases with uncontrollable disease
