FLIP Panometry diagnoses and disease states

		EGJ-DI (2.1–3.0 mm2/mm Hga)
	EGJ-DI (0–2 mm2/mm Hg)	Max D <12 mm Bag pressure >20 mm Hg	Max D >12 mm Bag pressure >20 mm Hg	EGJ-DI (3.1–9.0 mm2/mm Hg)	EGJ-DI (>9.0 mm2/mm Hg)
RACs	EGJOO with normal contractile response	EGJOO with normal contractile response	Normal contractile response	Normal contractile response	Normal contractile response with increased EGJ distensibility
DDCR	EGJOO w/DDCR	EGJOO w/DDCR	DDCR	DDCR	DDCR with increased EGJ distensibility
Absent	EGJOO w/absent contractile response	EGJOO w/absent contractile response	Absent contractile response	Absent contractile response	Absent contractile response with increased EGJ distensibility
RRCs	EGJOO w/retrograde contractile response	EGJOO w/retrograde contractile response	Retrograde contractile response	Retrograde contractile response	Retrograde contractile response with increased EGJ distensibility

For application to endoscopy-negative dysphagia patients without a hernia > 3 cm or mechanical obstruction/esophagitis. EGJ-distensibility index (DI) at EF-322 60 mL fill volume.

DDCR, disordered and/or diminished contractile response; EGJ, esophagogastric junction; EGJOO, EGJ outflow obstruction FLIP, functional lumen imaging probe; RAC, repetitive anterograde contraction; RRC, repetitive retrograde contraction.

^aRule out mechanical stricture if Max diameter is less than 18 and there is a fixed plateau max diameter during volumetric distention-strongly consider obtaining a timed barium esophagram with barium tablet.
