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

 

ON period

OFF period

Gastric emptying (minutes) (n = 20)

89 (34–142)

IBS-M (n = 9)

42 (5–360)

66 (4–121)

One-hour velocity following duodenal passage (meters/hour) (n = 20)

1.29 (0.56-2.3)

1.19 (0.58-1.72)

IBS-D (n = 11)

1.29 (0.67-2.9)

0.48 (0.1-1.02)

0.42 (0.11-0.87)

IBS-D (n = 11)

0.49 (0.17-1.02)

0.36 (0.11-0.7)

IBS-M (n = 9)

  1. IBS-D stand for diarrhoea-predominant IBS and IBS-M stand for mixed IBS.
  2. Values are expressed as median and range.
