BACKGROUND
The relation of
demographic and psychological factors to the presence and extent of gut
transit impairment in the functional gastrointestinal disorders has
received little attention.
AIMSTo compare the psychosocial
and demographic features of patients with functional gastrointestinal
disorders and delayed transit in one region of the gastrointestinal
tract with those displaying more widespread delayed transit (that is,
delay in two or three regions), and those with normal transit in all
three regions.
PATIENTSOf 110 outpatient
participants who satisfied standardised criteria for functional
gastrointestinal disorders, 46 had delayed transit in one region, 32 had delay in two or three regions, and 17 exhibited normal transit in
all regions.
METHODSTransit in the stomach, the
small intestine, and the large intestine was assessed concurrently
using a wholly scintigraphic technique; psychological status was
assessed using established psychometric measures.
RESULTSPatients with delayed
transit displayed demographic and psychological features that
contrasted with patients with normal transit in all regions. In
particular, widespread delayed transit featured female sex, a highly
depressed mood state, increased age, frequent control of anger, and
more severe gastric stasis, while the features distinguishing normal
transit were male sex and high levels of hypochondriasis.
CONCLUSIONThese data suggest the
existence of a distinct psychophysiological subgroup, defined by the
presence of delayed transit, in patients with functional
gastrointestinal disorders.
