TL;DR: The proposed constipation scoring system correlated well with objective physiologic findings in constipated patients to allow uniformity in assessment of the severity of constipation.
Abstract: PURPOSE: Constipation is a common complaint; however, clinical presentation varies with each individual. The aim of this study was to assess a standard scoring system for evaluation of constipated patients. MATERIALS AND METHODS: All consecutive patients with idiopathic constipation who were referred for anorectal physiologic testing were assessed. A subjective constipation score was calculated based on a detailed questionnaire that included over 100 constipation-related symptoms. Based on the questionnaire, scores ranged from 0 to 30, with 0 indicating normal and 30 indicating severe constipation. The constipation score was then compared with the objective findings of the physiology tests, which include colonic transit time (CTT), anal manometry (AM), cinedefecography (CD), and electromyography (EMG). Colonic inertia was defined as diffuse marker delay on CTT without evidence of paradoxical contraction on AM, CD, or EMG. Pelvic outlet obstruction was defined as paradoxical puborectalis contraction, rectal prolapse or rectoanal intussusception, rectocele, or sigmoidocele. RESULTS: A total of 232 patients (185 females and 47 males) of a mean age of 64.9 (range, 14–92) years were evaluated. All patients had a score of more than 15; on evaluation of the significance of different symptoms in the constipation score with the Pearson's linear correlation test, 8 of 18 factors were identified as significant (P<0.05). These factors included frequency of bowel movements, painful evacuation, incomplete evacuation, abdominal pain, length of time per attempt, assistance for evacuation, unsuccessful attempts for evacuation per 24 hours, and duration of constipation. All 232 patients had objective obstruction attributable to one or more of the following causes: paradoxical puborectalis contraction (81), significant rectocele or sigmoidocele (48), rectoanal intussusception (64), and rectal prolapse (9). CONCLUSION: The proposed constipation scoring system correlated well with objective physiologic findings in constipated patients to allow uniformity in assessment of the severity of constipation.

TL;DR: This is the first attempt at defining criteria for functional gastrointestinal disorders in infancy, childhood, and adolescence and it is suggested that clinicians refer to the criteria established for the adult population.
Abstract: This is the first attempt at defining criteria for functional gastrointestinal disorders (FGIDs) in infancy, childhood, and adolescence. The decision-making process was as for adults and consisted of arriving at consensus, based on clinical experience. This paper is intended to be a quick reference. The classification system selected diVers from the one used in the adult population in that it is organized according to main complaints instead of being organ-targeted. Because the child is still developing, some disorders such as toddler’s diarrhea (or functional diarrhea) are linked to certain physiologic stages; others may result from behavioral responses to sphincter function acquisition such as fecal retention; others will only be recognizable after the child is cognitively mature enough to report the symptoms (e.g., dyspepsia). Infant regurgitation, rumination, and cyclic vomiting constitute the vomiting disorders. Abdominal pain disorders are classified as: functional dyspepsia, irritable bowel syndrome (IBS), functional abdominal pain, abdominal migraine, and aerophagia. Disorders of defecation include: infant dyschezia, functional constipation, functional fecal retention, and functional nonretentive fecal soiling. Some disorders, such as IBS and dyspepsia and functional abdominal pain, are exact replications of the adult criteria because there are enough data to confirm that they represent specific and similar disorders in pediatrics. Other disorders not included in the pediatric classification, such as functional biliary disorders, do occur in children; however, existing data are insufficient to warrant including them at the present time. For these disorders, it is suggested that, for the time being, clinicians refer to the criteria established for the adult population. (Gut 1999;45(Suppl II):II60‐II68)

TL;DR: More than one third of an unselected middle-aged population reported chronic abdominal pain or disturbed defecation, and more than one in six had symptoms compatible with the irritable bowel syndrome.

TL;DR: A systematic review of the published literature found that childhood constipation is a common problem worldwide and large epidemiologic studies with the use of generally accepted diagnostic criteria are needed to define the precise prevalence of constipation.
