Active clinical trials for "Constipation"

Our null hypothesis states that the two techniques (Sitzmarks radioopaque markers and SmartPill) are equivalent and is demonstrated if the study population shows a correlation of 0.7 or higher.

Hypotheses: High definition manometry (HDM) is safe and feasible in humans; HDM accurately characterizes anorectal anatomy and function in healthy humans; HDM provides comparable information regarding the structure and function of the anorectal region, to that obtained from ano-rectal manometry and anal ultrasonography (AUS), in patients with fecal incontinence or constipation. Methods: 20 healthy volunteers, 20 patients with fecal incontinence, 20 patients with constipation will be recruited. Because anorectal disorders are more common in women, the investigators will recruit approximately 8 men and 12 women in each group. Each subject will undergo anorectal manometry, anal ultrasound and high definition manometry. Data Analysis: Spearman correlational analysis will be performed to compare the parameters listed above. Also, the diagnostic yield of anal ultrasonography vs HDM in identifying anatomic sphincter defects will be assessed.

Terminal constipation affects 13 to 20% of the french population. Anismus is defined by an absence of relaxation or a paradoxical contraction of the striated anal sphincter muscle during defecation. Anismus is one of the main causes of terminal constipation. Anismus diagnosis is retained if 2 out of 3 examinations (manometry, electromyogram, defecography) are positive. EndoFLIP® is a new medical device developed to measure distensibility of a hollow organ. Anal EndoFLIP® l could be a more sensitive and specific tool for detecting anismus in patients with distal constipation. 60 patients suffering from distal constipation will be included in order to perform, in addition to the usual examinations, an anal EndoFlip in order to test the sensitivity and specificity of this method for the diagnosis of anismus.

This study is a single site prospective controlled trial assessing two educational interventions designed to educate local pediatric Primary Care Physicians (PCP) and nurses on collaboratively developed treatment guidelines for pediatric constipation. The study aims to assess the impact of an Spaced Education game to aid the implementation of the management guideline. PCP adherence to recommended treatment will be assessed in addition to PCP satisfaction with the educational methods, constipation knowledge and patient outcomes.

In this prospective study the function of gastrointestinal tract was assessed using constipation questionnaire (Rome criteria and bowel function index).

Anorectal 3D manometry (3D HRAM) is the most advanced version of manometric equipment that measures pressures along the anal canal in a very detailed manner. It provides complete data about pressure profile of anorectum and may indicate impaired defecation dynamics. Balloon expulsion test (BET) is a cheap, easy way to diagnose constipation as the result of outlet obstruction. Our aim is to compare this two methods of diagnosis of dyssynergic defecation and to find the correlation between this diagnostic equipment.

The projects aim is to investigate the intestinal function of patients suffering from Prader-Willi Syndrome. The methods used are ultrasonographic measurement of the rectal diameter and gastrointestinal transit time

The purpose of the study is to determine the diurnal variation of rectal diameter in healthy and constipated children using transabdominal ultrasound.

Compare changes in bowel function before, 6 months and one year after Robotic-assisted laparoscopic sacral colpopexy. Compare objective anatomic outcomes before, 6 months and one year after Robotic-assisted laparoscopic sacral colpopexy.

This qualitative research is to assess the validity of the stool symptom screener that will be used in patients with chronic opioid-induced constipation to determine the adequacy of their response to laxatives.
