Abstract
INTRODUCTION: The Endoluminal Functional Lumen Imaging Probe (Endoflip™) is a balloon-based catheter that provides real-time, objective feedback regarding the distensibility of any sphincter in the gastrointestinal tract. Usage of the Functional Lumen Imaging Probe (FLIP) has not been standardized, which has limited the interpretation and generalizability of published data. The purpose of this consensus statement is to provide a standardized protocol for obtaining FLIP measurements in order to create a more uniform approach to data collection. METHODS: Five expert foregut surgeons, all of whom utilize the FLIP system in their daily practice, convened on March 19, 2019, to create a standardized protocol for obtaining FLIP measurements during hiatal hernia repair and fundoplication, magnetic sphincter augmentation, laparoscopic Heller myotomy, and peroral endoscopic myotomy. Existing literature was presented and reviewed. Each step of the protocol was discussed in detail until a unanimous consensus was reached. RESULTS: A standardized protocol was developed for obtaining FLIP measurements during hiatal hernia repair and fundoplication, magnetic sphincter augmentation, laparoscopic Heller myotomy, and peroral endoscopic myotomy. CONCLUSION: The FLIP impedance planimetry system is the only technology available that provides surgeons an objective way to assess the tightness of a fundoplication or adequacy of a myotomy during an operation. While considerable research remains to correlate FLIP measurements to patient outcomes, this consensus statement will provide standardization of data collection among FLIP users that will enhance the understanding of future study results.
