Scott Harris and Oranee T. Daniels 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. 25, 26 [...]... extrapolated to help assist in the diagnosis of constipation (Table 2) Fig 1 Bristol stool chart (Lewis and Heaton, 1997) 6 Constipation – Causes, Diagnosis and Treatment Bristol stool chart (see Fig 1.)
