Abstract:

BACKGROUND AND AIMS: Transoral incisionless fundoplication (TIF) is an established safe endoscopic technique for the management of GERD but with variable efficacy. In the last decade, the TIF technology and technique have been optimized and more widely accepted but data on outcomes outside clinical trials are limited. We tracked patient-reported and clinical outcomes of GERD patients after TIF 2.0. METHODS: Patients with BMI < 35, hiatal hernia < 2cm, and confirmed GERD with typical and/or atypical symptoms from 9 academic and community medical centers were enrolled in a prospective registry and underwent after TIF 2.0 performed by gastroenterologists and surgeons. The primary outcomes were safety and clinical success (response in > 2 of 4 endpoints). Secondary endpoints were symptom improvement, acid exposure time (AET), esophagitis healing, proton pump inhibitor (PPI) use, and satisfaction. Outcomes were assessed at last follow-up within 12 months. RESULTS: 85 patients underwent TIF 2.0, 81 were included in the outcomes analysis. Clinical success was achieved in 94%, GERD-HRQL scores improved in 89%, and elevated RSI score normalized in 85% of patients with elevated baseline. Patient satisfaction improved from 8% to 79% (p < 0.0001). At baseline, 81% were taking at least daily PPI, while 80% were on no or occasional PPI after TIF 2.0 (p < 0.0001). Esophageal AET was normal in 72%, greater with an optimized TIF 2.0 valve > 300 degree circumference, > 3cm length (94% vs 57%, p = 0.007). There were no TIF 2.0-related serious adverse events. CONCLUSION: TIF 2.0 is a safe and effective endoscopic outpatient treatment option for select patients with GERD.
