- Brief Summary
Barrett's esophagus (BE) is a precancerous lesion characterized by the replacement of the normal stratified squamous epithelium of the distal esophagus by intestinal metaplasia (IM). Non-dysplastic BE may progress to low-grade dysplasia (LGD), to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC). Endoscopic ablation is safe and effective for complete eradication of BE. However, recurrence is common. Cumulative incidence rate of BE recurrence is up to 30% in the third year. Thus, achieving complete eradication of IM, patients should undergo surveillance indefinitely with serial endoscopy to assess for recurrence of BE. In addition, BE patients have been committed to life-long proton pump inhibitor (PPI) therapy, but increasing concerns about adverse effects has led to alternative therapies. Studies have showed that laparoscopic Nissen fundoplication may decrease recurrence of BE after endoscopic ablation. Transoral Incisionless Fundoplication (TIF) is an endoscopic procedure that mechanically creates fundoplication similar to traditional operative Nissen fundoplication. The role of TIF in patients with BE whom underwent successful endoscopic ablation has not been fully investigated.

Group Intervention Description post-ablation Barrett's patients TIF The patients with known prior diagnosis of histologically-confirmed Barrett's esophagus with or without dysplasia who have documentation of complete remission of Barrett's esophagus by endoscopy and histology after endoscopic ablation
- Primary Outcome Measures
Name Time Method Percentage of participants with normal esophageal acid exposure time 6 months Normal esophageal acid exposure time is 6 percent or less.
- Secondary Outcome Measures
Name Time Method Percentage of participants that are able to discontinue PPI post TIF 6 months Percentage of participants that are able to discontinue PPI post TIF will be assessed at 6 months.
Incidence of esophagitis post-TIF 6 months The presence of esophagitis on upper endoscopy.
Proportion of patients with recurrence of BE and BE-related dysplasia Up to 36 months Proportion of patients with recurrence of BE and BE-related dysplasia will be assessed up to 36 months.
Number of TIF-related serious adverse events Up to 36 months Treatment related serious adverse events (SAEs) including hospitalization, unscheduled emergency room or physician visits for post-TIF symptoms), bloating, dysphagia.
Change in quality of life as assessed by the GERD-Health-related quality of life Questionnaire Baseline, 6, 12, 24 and 36 months The GERD-Health-related quality of life (HRQL) Questionnaire has an overall score range of 0 to 75. Each item is scored from 0 to 5, with a higher score indicating worse symptoms and poorer quality of life.
Change in Gastroesophageal Reflux Disease (GERD) symptoms assessed by the Reflux Symptom Index (RSI) Baseline, 6, 12, 24 and 36 months The RSI is a nine-item self-administered outcome questionnaire designed to document reflux symptoms and severity. Each item is scored on a scale of 0 (no problem) to 5 (severe problem), with overall score ranging between 0 and 45. Higher scores mean more severe symptoms. RSI \> 13 may be indicative of significant reflux disease.
