      The functional luminal imaging probe (FLIP), a device developed and pioneered at Northwestern Medicine, is a diagnostic tool utilized to measure esophageal and sphincter physiology. Since its development, its use has expanded both intra- and post-operatively to directly evaluate treatment effect. However, utilization of this tool in an open esophageal case to provide real-time diameter, volumetric and pressure data, allowing for a tailored surgical intervention, has not been established in the literature. We present a novel case that demonstrates innovative use of an established diagnostic instrument that has the capacity to provide surgeons with valuable real-time intra-operative data. The authors propose intra-operative use of FLIP can support real-time surgical decision making and optimize clinical care.
