A randomised, controlled study of small intestinal motility in patients treated with sacral nerve stimulation for irritable bowel syndrome

Table 3 Inter-period change in the velocity of the magnet-capsule through the small intestine

One-hour following duodenal passage	Change ON-OFF	Change OFF-ON	p
IBS-D and IBS-M (n = 19)	0 (-1.07, 0.63)	0.27 (-0.59, 1.12)	0.25
IBS-D (n = 11)	0.09 (-0.55, 0.45)	0.14 (-0.59, 1.12)	0.68
IBS-M (n = 8)	-0.08 (-1.07, 0.63)	0.27 (0.22, 0.32)	0.32
One- hour following ingestion of meal	Change ON- OFF	Change OFF- ON	p
IBS-D and IBS-M (n = 17)	-0.13 (-0.46, 0.23)	0.01 (-0.48, 0.59)	0.14
IBS-D (n = 10)	-0.04 (-0.17, 0.09)	0.16 (-0.09, 0.59)	0.30
IBS-M (n = 7)	-0.13 (-0.46, 0.23)	-0.31 (-0.48, -0.15)	0.26

IBS-D and IBS-M stand for diarrhoea-predominant and mixed irritable bowel syndrome. Values are expressed in meters pr. hour as median change (the difference in the velocity of the magnet-capsule from ON to OFF or OFF to ON) and range.
