Preface
Constipation is common in both adults and children. Estimates would suggest a
median prevalence of around 12-16% in the general population.
1
While regarded as a
minor nuisance in some cases, its consequences can be severe, with a substantial
impact on quality of life.
2
Secondary faecal soiling has a profound psychological effect
at all ages.
This book provides specific contributions which clarify the pathogenesis, diagnosis, and
therapy of constipation for the general population and also for certain high risk groups.
Surprisingly, consensus definitions of constipation have been hard to achieve, but that
achieved by the PACCT group
3
for children included having at least 2 of the following
features within the last 8 weeks:
Fewer than 3 bowel movements per week
More than one episode of fecal incontinence per week
Large stools in the rectum or palpable on abdominal examination
Passing of stools so large that they obstruct the toilet
Retentive posturing and withholding behavior
Painful defecation.
Importantly, it may not be recognised, only coming to attention because of abdominal
pain, soiling or behavioural disturbances. The chapter by Kathleen McGrath critically
examines the impact defaecation disorders have in children and the diagnostic criteria
used to identify them.
Defaecation disorders are also much more prevalent in certain groups. The very young
and the elderly
4, 5
are at particular risk. They also pose a particular difficulty for both
children and adults with developmental disabilities
6
, neurological dysfunction and
spinal cord injury.
7
Medical and surgical therapy may also lead to constipation
through the use of potent analgesics such as opiods. The chapters by Caterina Aurilio
and Kelly Sprawls provide insights into the aetiology of opiod-induced constipation
and pharmaceutical approaches to avoiding it and its therapy. Occasionally,
constipation may be the presenting feature of another condition such as thyroid
disease or colorectal malignancy.
8
The relationship between colorectal tumors and
colonoscopy is addressed in the chapter by Brusciano. The chapters by Luca Galleli
X Preface
and Elsie Gulick provide insights into the impact of the broad spectrum of
neurological disorders and multiple sclerosis respectively on colorectal dysfunction.
In most situations, constipation occurs in otherwise well individuals. The pathogenesis
in these cases is usually proposed to be inadequate dietary fibre, a sedentary lifestyle,
or poor toileting techniques. The chapter by Tomoko Fujiwara provides an insightful
and unique window into the impact of the all too common habit of skipping breakfast
on bowel function.
Diagnosis is usually straightforward, but it often helpful to make reference to
diagnostic criteria such as that achieved by the PACCT group. Further diagnostic
testing is not usually required, but can be invaluable in specific instances. The chapter
on diagnostic tests (Catto-Smith et al.) provides a review of the available testing
techniques. While abdominal radiography is often employed, it is rarely adds much.
Studies of colorectal motility
9, 10
provide an immense amount of information but are
either expensive, invasive, or difficult to interpret
11
. However, they have enabled a
better understanding of the motility dysfunction responsible for constipation.
12
Sensory dysfunction is clearly important as many patients are unaware of the extent of
rectal filling.
13
These type of studies have however meant that entities such as slow
transit constipation, anorectal incoordination, sphincteric dysfunction and the basis for
constipation in irritable bowel syndrome are now much better understood
14
. The
chapter by Brian Dobson provides a novel hypothesis into the pathogenesis of
defaecation disorders in irritable bowel syndrome.
In many situations, otherwise uncomplicated constipation will respond to simple
interventions such as attention to diet
15
and toileting, but in other patients it can be
extraordinarily difficult to achieve therapeutic success. Medications generally function
through either assisting colorectal contractility or softening the stool.
16
Unfortunately,
drugs only offer temporary relief if the primary cause is unable to be improved. Recent
interest has centred on possibly dysbiotic colonic flora in the hope that probiotics
17
may be helpful. There are a variety of traditional and complementary medications that
are used widely in the community.
18
Behavioural therapies are often very effective in children,
19, 20
and biofeedback
modalities have attracted a great deal of interest, particularly in adults.
21
Better understanding of the pathophysiology of defaecation disorders has opened the
doors to novel treatments. Abnormalities in the excitatory cells primarily responsible
controlling gastrointestinal motility have been postulated to have a major role in
certain types of constipation such as slow transit
22
and even that associated with
diabetes.
23
The chapter by Christian Breuer provides a good understanding of the
Interstitial Cell of Cajal – a central player in gastrointestinal dysmotility and slow
transit constipation. Sacral stimulation is certainly effective, but is invasive. A very
exciting new area is that of transabdominal electrical stimulation,
24
which appears to
offer the unenviable combination of low cost, ease of use, durability of effect to an
otherwise treatment-resistant population.
