Myoelectric activity and motility of the Roux limb after cut or uncut Roux-en-Y gastrojejunostomy

Table 1 Myoelectric activity of the Roux limb in the two groups

Group (n = 7)	Frequency of	Amplitude of	Incidence of	Amplitude of	MMC phase III	MMC
	slow wave	slow wave	spike potential	spike potential	duration	cycle
	(cpm)	(mV)	(%)	(mV)	(min)	(min)
Cut group	9.5 ± 1.1	0.48 ± 0.06	56.6 ± 6.4	0.23 ± 0.06	4.4 ± 0.8	55.3 ± 8.2
Uncut group	14.4 ± 1.9a	1.15 ± 0.15b	98.2 ± 10.4a	0.58 ± 0.08b	6.5 ± 1.1a	42.5 ± 6.8a

^aP < 0.05,

^bP < 0.01 vs cut group.
