Outcomes After Transoral Incisionless Fundoplication (TIF) Following Successful Endoscopic Ablation for Barrett's Esophagus

Enrolling by invitation

Conditions studied: Barrett Esophagus, Transoral Incisionless Fundoplication

In brief

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.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age 18 - 75 years
• Known prior diagnosis of histologically-confirmed BE with or without dysplasia (as defined by the presence of specialized columnar epithelium anywhere in the tubular esophagus with >= 1 cm of circumferential involvement or non-circumferential involvement of specialized columnar epithelium) [Prague class >1] and history of initial complete eradication-IM following endoscopic ablation for Barrett's esophagus.
• Documentation of complete ablation of BE by endoscopy and histology after radiofrequency or cryotherapy ablation on two endoscopic examinations at least 3 months apart, within most recent endoscopy performed within 6 months. Pathologic diagnosis determined by the expert pathologist at each site.
• On PPI therapy, who opt for an intervention over lifelong drug dependence.
• Hiatal hernia ≤ 2 cm or Hill grade < 2 [unless patients undergoing combined TIF and hiatal hernia repair]
• Abnormal esophageal acid exposure [Percent esophageal acid exposure time > 6% defined by Bravo ph monitoring (48 - 96 hours study)
• Able to provide informed consent

You may not qualify if…

• Age < 18 or > 75 years
