OBJECTIVES: This study was designed to evaluate whether detailed symptom analysis would help to identify pathophysiologic subgroups in chronic constipation. METHODS: In 190 patients with chronic constipation (age, 53 (range, 18–88) years; 85 percent of whom were women), symptom evaluation, transit time measurement (radiopaque markers), and functional rectoanal evaluation (proctoscopy, anorectal manometry, defecography) were performed. Patients were classified on the basis of objective data from… 
Clinical value of symptom assessment in patients with constipation
PURPOSE: This study was designed to evaluate symptoms and clinical findings in a prospective series of patients with chronic constipation. METHODS: A total of 155 consecutive patients with
Linear discriminant analysis of symptoms in patients with chronic constipation
TLDR
This new scoring system is a valid technique to assist in the diagnosis of constipation and is the first study using appropriate statistical methodology to demonstrate a discriminatory ability of multiple symptoms in constipation.
Constipation assessed on the basis of colorectal physiology.
TLDR
No single test could reliably identify any of the pathophysiologic subgroups of constipation in patients with chronic constipation.
Categorization of dysmotility in patients with chronic constipation and its significance for management.
TLDR
The symptoms, DARE, GITT and ARM are effective methods of evaluating the dysmotility patterns in patients with chronic constipation and could improve the diagnostic rate of OOC, and GITT assists in diagnosis of STC.
Chronic constipation - the role of clinical assessment and colorectal physiologic tests to obtain an etiologic diagnosis.
TLDR
The etiologic diagnosis of chronic constipation can be achieved in most of patients on a clinical basis and some symptoms may be significantly related to specific diagnoses.
Causes of idiopathic constipation in Thai patients: associations between the causes and constipation symptoms as defined in the Rome II criteria.
TLDR
Prevalence of pathophysiologic conditions associated with idiopathic constipation in Thai patients are similar to Western countries, and patients with colonic inertia and anorectal dysfunction plus Colonic inertia had a higher prevalence of infrequent bowel movement than patients with normal transit constipation.
Linear Discriminant Analysis of Symptoms in Patients with Chronic Constipation: Validation of a New Scoring System (KESS)
TLDR
This new scoring system is a valid technique to assist in the diagnosis of constipation and is the first study using appropriate statistical methodology to demonstrate a discriminatory ability of multiple symptoms in constipation.
Dyssynergic Defecation: Demographics, Symptoms, Stool Patterns, and Quality of Life
TLDR
Most patients with dyssynergia reported an excessive need to strain, feeling of incomplete evacuation and abdominal bloating and one half used digital maneuvers, which significantly affected quality of life, particularly in women.
Slow transit constipation: clinical and aetiological studies.
TLDR
Mutational screening of some early-onset cases for a possible congenital pathogenetic mechanism, based on the observation that some STC patients had relatives with Hirschsprung's disease demonstrated that mutation of 2 important genes now implicated in this disorder were not a frequent cause.
Prevalence and Clinical Characteristics of Dyssynergic Defecation and Slow Transit Constipation in Patients with Chronic Constipation
TLDR
Patients with chronic constipation who do not respond to initial treatments often need further evaluation for dyssynergic defecation (DD) and slow transit constipation (STC) to better understand their pathophysiology of symptoms and help direct treatment.

Is constipation a disorder of defecation or impaired motility?: distinction based on defecography and colonic transit studies.
TLDR
It is suggested that constipation is often a disorder of defecation rather than an impairment of colonic motility.
Chronic severe constipation. Prospective motility studies in 25 consecutive patients.
TLDR
It is indicated that a high percentage of patients with more severe degrees of constipation have a serious but sometimes treatable disorder of bowel function, rather than the irritable bowel syndrome.
An examination of the reliability of reported stool frequency in the diagnosis of idiopathic constipation.
TLDR
The diagnosis of idiopathic constipation should be supported by the use of stool diaries and a colon transit study, and anorectal manometry was not helpful in discriminating between those who satisfied the criterion for constipation and those who did not.
Different patterns of intestinal transit time and anorectal motility in painful and painless chronic constipation.
TLDR
The data show that two different patterns of motor abnormalities can be recognised in constipated patients and the presence of colonic pain can suggest the characteristics of the underlying motor abnormality.

TLDR
Measurement of colonic transit time in patients with disordered evacuation studies is useless from a clinical point of view, because abnormal segmental transit time is the result of outlet obstruction in most cases and will return to normal after adequate treatment.
Correlates of constipation in an ambulatory elderly population.
TLDR
Elderly people who report the use of multiple drugs, pain in the abdomen, and hemorrhoids are at increased risk for constipation, and 11 factors of significance were found to correlate with self-reported constipation.
Self-reported diarrhea: what does it mean?
TLDR
It is concluded that the term "diarrhea" should be interpreted very cautiously in epidemiological studies or clinical trials, as it is unlikely to accurately reflect symptoms of diarrhea.
Bowel patterns among subjects not seeking health care. Use of a questionnaire to identify a population with bowel dysfunction.
To understand the disorders of bowel motility, it is important to know the range of bowel patterns in the general population. We have devised a brief self-administered questionnaire which, when used
Is the volume retained after defecation a valuable parameter at defecography?
TLDR
It is concluded that defecographic findings do not in general explain incomplete emptying or the sense of incomplete empties, but they may determine the localization of the retained volume.
Effect of stool size and consistency on defecation.
TLDR
It is suggested that more effort is required to expel stools from the rectum if they is small and hard than if they are large and soft.
