Background and aims: The regular overnight migrating motor complex (MMC) ensures that the normal fasting small bowel water content (SBWC) is minimised. We have applied our recently validated non-invasive magnetic resonance technique to assess SBWC in newly diagnosed coeliac disease (CD), scleroderma (SCD) and irritable bowel syndrome (IBS) conditions, possibly associated with small intestinal bacterial overgrowth (SIBO).
Methods: 20 CD and 15 SCD patients with gastrointestinal symptoms were compared to 20 healthy volunteers (HV) and 26 IBS with diarrhoea (IBS-D) patients as previously reported. All underwent a fasting, magnetic resonance imaging (MRI) scan on a 1.5 T Philips Achieva MRI scanner to assess fasting SBWC and colonic volumes. Stool and symptom diaries were completed for 1 week.
Results: Median (Interquartile range, IQR)
Compared to healthy volunteers, all the patients had significantly increased stool frequency and Bristol stool form score. SBWC was significantly increased in CD 109(53-224) vs. 53(31-98) mL in HV, p [less than] 0.01 and 42 (28-67) in IBS-D, p [less than] 0.01. Variable increase in SBWC was also found in SCD, median 77(39-158) but this was not significant, p=0.2. Colonic volumes were similar for all groups being 547 (442-786) for CD, 511 (453-789) for SCD, 612 (445-746) for HV and 521 (428-757) mL for IBS-D. When CD patients were subdivided according to the Marsh classification, the higher grades had larger colonic volumes.
Conclusion: Fasting SBWC as assessed by MRI is significantly increased in newly diagnosed CD and SCD but decreased in IBS-D. Future studies should test whether increased resting fluid predisposes to SIBO.
