Management of Barrett's Esophagus: Long-term PPI Therapy
Patients with Barrett's esophagus should remain on long-term PPI therapy indefinitely, as PPIs reduce the risk of progression to esophageal adenocarcinoma. 1, 2
Rationale for Long-term PPI Use in Barrett's Esophagus
- Barrett's esophagus represents a precursor lesion to esophageal adenocarcinoma, and evidence shows that PPIs reduce this cancer risk 1
- The American Gastroenterological Association explicitly recommends against discontinuing PPIs in patients with Barrett's esophagus 1, 2
- Patients with Barrett's esophagus have high levels of nocturnal esophageal acid exposure, which contributes to disease progression 1
- PPI therapy is effective for symptom control and healing of esophagitis in Barrett's esophagus patients 1
- Prospective cohort studies demonstrate that PPI use is associated with a reduced risk of neoplastic progression in Barrett's esophagus patients 3
Evidence Supporting Long-term PPI Use
- A multicenter prospective cohort study found that PPI use reduced the risk of neoplastic progression by 59% (hazard ratio 0.41) compared to non-PPI users 3
- Prolonged PPI use and good adherence were associated with additional protective effects against progression to dysplasia or cancer 3
- Patients who delayed using PPIs for 2+ years after Barrett's diagnosis had 5.6 times higher risk of developing low-grade dysplasia and 20.9 times higher risk of developing high-grade dysplasia or adenocarcinoma 4
- Long-term PPI treatment (up to 13 years) was associated with development of squamous islands in Barrett's esophagus and a low incidence of esophageal adenocarcinoma (0.31%) 5
PPI Dosing Considerations
- For patients with Barrett's esophagus who don't respond clinically to once-daily therapy, twice-daily PPI therapy may be recommended 1
- Patients with long-segment Barrett's esophagus (>3 cm circumferentially) have particularly high levels of nocturnal acid exposure and may benefit from more aggressive acid suppression 1
- There is no definitive evidence that all Barrett's esophagus patients should routinely receive double-dose PPI therapy 1
- The goal is to normalize esophageal acid exposure, though clinical studies haven't definitively proven that this reduces cancer risk 1
Alternative Management Options
- Anti-reflux surgery (Nissen fundoplication) does not offer advantages over medical treatment with PPIs for preventing progression to dysplasia or cancer in Barrett's esophagus 1
- Anti-reflux surgery may be considered as an alternative for patients who are intolerant to PPIs or concerned about long-term PPI medication 1
- NSAIDs/aspirin may decrease esophageal cancer incidence, but the potential benefit may not outweigh medication risks for all patients 1
Important Caveats and Considerations
- Despite PPI therapy, some patients with Barrett's esophagus may still have continued abnormal levels of gastroesophageal reflux even without symptoms 1
- Regular endoscopic surveillance remains necessary for Barrett's esophagus patients on PPI therapy to monitor for dysplasia development 1
- One study suggested high-adherence and long-term PPI use might be associated with increased risk of dysplasia/adenocarcinoma, possibly due to confounding by indication 6
- The decision to continue PPI therapy should consider the patient's overall risk profile, including cardiovascular risk factors, as cardiovascular deaths are more common than esophageal adenocarcinoma deaths in Barrett's esophagus patients 1
In conclusion, the evidence strongly supports continuous, long-term PPI therapy for patients with Barrett's esophagus to reduce the risk of progression to dysplasia and adenocarcinoma. This recommendation is consistent across multiple gastroenterological society guidelines.
