Functional Luminal Imaging Probe (FLIP) as an Adjunctive Modality in Evaluation of Esophageal Dysmotility

Abstract

The Functional Luminal Imaging Probe (FLIP) has emerged as a valuable adjunctive tool in the evaluation of esophageal diseases. Using volumetric distension, FLIP can assess secondary peristalsis and detect esophageal abnormalities that may not be evaluated by high-resolution manometry (HRM). In certain clinical settings, FLIP may allow for deferral of HRM. In therapy for esophageal diseases, FLIP has demonstrated value for its real-time interpretation, which can be used intra-procedurally to tailor therapy and to predict post-therapy outcomes. The future of FLIP looks promising as surgeons and gastroenterologists place increasing emphasis on non-manometric data to diagnose esophageal motility disorders.
