“…Significant differences in static but not dynamic compliance were found between IBS patients and normal healthy subjects. Dynamic and static compliance were not significantly different between diarrhea and constipation predominant IBS patients 110. However, these results were inconsistent to other studies showing lower dynamic compliance in diarrhea than in constipation predominant IBS patients 111-113.…”

Altered motility remains one of the important pathophysiologic factors in patients with irritable bowel syndrome (IBS) who commonly complain of abdominal pain and stool changes such as diarrhea and constipation. The prevalence of IBS has increased among Asian populations these days. Gastrointestinal (GI) physiology may vary between Asian and Western populations because of differences in diets, socio-cultural backgrounds, and genetic factors. The characteristics and differences of GI dysmotility in Asian IBS patients were reviewed. MEDLINE search work was performed including following terms, 'IBS,' 'motility,' 'transit time,' 'esophageal motility,' 'gastric motility,' 'small intestinal motility,' 'colonic motility,' 'anorectal function,' and 'gallbladder motility' and over 100 articles were categorized under 'esophagus,' 'stomach,' 'small intestine,' 'colon,' 'anorectum,' 'gallbladder,' 'transit,' 'motor pattern,' and 'effect of stressors.' Delayed gastric emptying, slow tansit in constipation predominant IBS patients, rapid transit in diarrhea predominant IBS patients, accelerated motility responses to various stressors such as meals, mental stress, or corticotrophin releasing hormones, and altered rectal compliance and altered rectal accomodation were reported in many Asian studies regarding IBS. Many conflicting results were found among these studies and there are still controversies to conclude these as unique features of Asian IBS patients. Multinational and multicenter studies are needed to be performed vigorously in order to elaborate characteristics as well as differences of altered motililty in Asian patients with IBS.

“…In the literature, various methods are applied to determine rectal compliance from a pressure–volume curve [8–10]. Both the total fit and the dynamic compliance, which is the slope of the pressure–volume curve at its steepest point, are commonly used techniques to evaluate the compliance.…”

“…Visceral perception is generally measured in vivo using the barostat technique. Since its introduction, different distension protocols have been used and efforts have been made to optimise the distension protocols [8–10]. Whitehead and Delvaux [11] described a number of basic recommendations for the measurement of visceral perception and compliance.…”

“…MDP is defined by some investigators as the pressure at which respiratory waves appear for the first time in the volume curve [9, 13], whereas others define it as the pressure needed to reach a specific volume (e.g. pressure at which the volume reaches 25 ml) [4, 10]. Determination of the different parameters in one barostat procedure requires multiple consecutive distension protocols.…”

Alternative procedure to shorten rectal barostat procedure for the assessment of rectal compliance and visceral perception: a feasibility study

et al. 2012

BackgroundBarostat methodology is widely used for assessing visceral perception. Different barostat protocols are described with respect to the measurement of rectal compliance and visceral perception. The choice of protocols affects the duration, which is normally 60–90 min, and accuracy of the procedure. This study aimed to shorten the procedure by using the semi-random distension protocol for both compliance and visceral perception measurement and a correction based on rectal capacity (RC) instead of minimal distension pressure (MDP).MethodsTwelve irritable bowel syndrome (IBS) patients (7 females) and 11 healthy controls (8 females) underwent a barostat procedure. Compliance was determined during both a staircase distension and a semi-random protocol. Visceral perception data were compared as a function of pressure or relative volume, corrected for MDP or RC, respectively.ResultsCompliance measurement using the semi-random protocol instead of the staircase distension protocol resulted in an overestimation in healthy volunteers, but not in IBS patients. The overall conclusion that IBS patients had a lower compliance compared to controls was not different between protocols. Data presentation of the visceral perception scores as a function of corrected volume instead of pressures corrected for MDP did not alter the conclusion that sensation scores in IBS patients were higher as compared to healthy controls.ConclusionsThis study showed that barostat procedures may be shortened by approximately 20 min, without losing the ability to discriminate between healthy controls and IBS patients. A correction for RC instead of MDP may improve the accuracy of the procedure.Electronic supplementary materialThe online version of this article (doi:10.1007/s00535-012-0543-x) contains supplementary material, which is available to authorized users.
