Adverse events associated with transoral incisionless fundoplication (TIF) for chronic gastroesophageal reflux disease: a MAUDE database analysis

Background: Transoral incisionless fundoplication (TIF) has been used for treating chronic gastroesophageal reflux disease (GERD) refractory to medical therapy. We aim to investigate the complications associated with TIF using a national database. Methods: We analyzed post-marketing surveillance data from the FDA Manufacturer and User Facility Device Experience (MAUDE) database from Jan 2011 through Jan 2021. Results: During the study period, approximately 95 event cases reported to the FDA. Approximately 131 patient complications were identified. The number of adverse events declined from 2011 to 2016 (R2 = 0.96) but increased from 2016 to 2020 (R2 = 0.99). The most common adverse event was perforation (19.8%), followed by laceration 17.6%, bleeding (9.2%), and pleural effusion (9.2%). The most common patient complications were treated using endoscopic clips (12.3%), chest tube or drain insertion (12.3%), use of endoscopic retriever device (11.1%), esophageal stent (8.6%), and emergent or open surgery (11.1%). Conclusions: Adverse events from TIF range from mild to severe. Further research is needed to develop approaches aimed at reducing patient risks.
