The role of transoral incisionless fundoplication (TIF) in the management of gastroesophageal reflux disease (GERD) following peroral endoscopic myotomy (POEM): A pilot, prospective, patient-driven study.

BACKGROUND

Gastroesophageal reflux (GERD) is a concern after peroral endoscopic myotomy (POEM). Transoral incisionless fundoplication (TIF) has been recently described as a possible therapy for post-POEM GERD in case series.

METHODS

We prospectively enrolled patients undergoing POEM who agreed to participate in objective post-procedure GERD evaluation. Patients with objective evidence of GERD and suitable anatomy were offered TIF vs. proton pump inhibitor (PPI) only. Patients who underwent TIF were compared to those on PPI-only therapy after follow-up.

RESULTS

Of 21 enrolled POEM patients with objective testing, GERD was found in 11 (52%). Of those eligible for TIF, 4 (40%) opted to pursue TIF and were compared to those on PPI-only therapy ( n = 6). Three months post-TIF, 75% of patients had discontinued or significantly decreased PPI. There were no adverse events. GERD health-related quality of life scores were low and comparable between TIF (3.75 ± 6.2) and those who remained on PPI-only therapy (4.1 ± 5).

CONCLUSION

In this pilot, patient-driven prospective study, 75% of patients with post-POEM GERD undergoing TIF had stopped or significantly reduced PPI use. Post-POEM TIF is safe and effective and may be a viable alternative to PPI for POEM-related GERD; however, future studies should include a control arm and post-intervention pH monitoring.
