Figure 4 Functional luminal imaging probe
study demonstrating decreased oesophagogastric junction distensibility Figure 4 | Functional luminal imaging probe study demonstrating decreased oesophagogastric junction distensibility. Oesophagogastric junction (EGJ) distensibility in this patient with achalasia is 1.3 mm2 per mmHg. The optimal threshold for detecting achalasia is <2.8 mm2 per mmHg. a | The positioning of the functional luminal imaging probe (FLIP) device at the EGJ along with the stepwise distension protocol. b | The corresponding FLIP display and calculated values for cross-sectional area, pressure and EGJ distensibility index are shown. CSA, cross-sectional area; FLIP, functional lumen impedance planimetry. Kahrilas, P. J. et al.
