TABLE 4.

Relationship of secondary peristalsis (FLIP contractile response) and primary peristalsis (HRM) on follow-up testing after fundoplication.

		HRM CCv4.0 peristalsis patterns
		Normal	Ineffective esophageal motility	Absent contractility	Hypercontractile	Premature	Total
FLIP contractile Response	Normal	10 (16)	0 (0)*	0 (0)	0 (0)	1 (2)	11 (17)
	Borderline	14 (22)	5 (8)	1 (2)	2 (3)	0 (0)	22 (35)
	Impaired/disordered	12 (19)	6 (10)	1 (2)	0 (0)	1 (2)	20 (32)
	Absent	1 (2)	3 (5)	5 (8)*	0 (0)	0 (0)	9 (14)
	Spastic reactive	0 (0)	0 (0)	0 (0)	1 (2)	0 (0)	1 (2)
	Total	37 (59)	14 (22)	7 (11)	3 (5)	2 (3)	63 (100)

Note: Values in each cell are n (% of the total cohort that completed both high-resolution manometry (HRM) and functional lumen imaging probe (FLIP)).

^*p <0.05 in comparison to normal primary peristalsis.
