Pan-Colonic Pressurizations Associated With Relaxation of the Anal Sphincter in Health and Disease: A New Colonic Motor Pattern Identified Using High-Resolution Manometry (VSports最新版本)

Pan-colonic pressurizations associated with relaxations of the anal sphincter represent a new colonic motor pattern that seems to be defective in patients with treatment-refractory chronic constipation and may have a role in the transport of colonic gas and in the facilitation of the propagating sequence-induced colonic transport.

Intraluminal pressure patterns in the human colon assessed by high-resolution manometry

Intraluminal pressure patterns were elucidated using High Resolution Colonic Manometry during a baseline period and in response to a meal, in 15 patients with constipation, chronically dependent on laxatives, 5 healthy volunteers and 9 patients with minor, transient, IBS-like symptoms but no sign of constipation.

Effects of a Meal and Bisacodyl on Colonic Motility in Healthy Volunteers and Patients with Slow-Transit Constipation

It is shown that in patients with slow-transit constipation, the colonic motor response to a meal and to bisacodyl, as well as the perception of bisacODYl-induced propagated pressure waves is decreased.

Characterization of Simultaneous Pressure Waves as Biomarkers for Colonic Motility Assessed by High-Resolution Colonic Manometry

The high-resolution colonic manometry performed for the first time using an 84-sensor water-perfused catheter reveals coordination of activities in the colon, rectum and anal sphincters and may become of diagnostic value in patients with colonic dysmotility.

Absence of high amplitude propagating contractions in subjects with chronic spinal cord injury.

HAPC were not observed in individuals with SCI pre- or post-sleep, and a sleep-induced depression in general colonic motility was evident in SCI and control subjects.

VSports - 24-Hour Colonic Manometry in Pediatric Slow Transit Constipation shows Significant Reductions in Antegrade Propagation

Prolonged pancolonic manometry in children with STC showed significant impairment in antegrade propagating motor activity and failure to respond to normal physiological stimuli, and HAPS occurred with normal frequency, suggesting significant clinical differences between STC in children and adults.

"VSports最新版本" Altered periodic rectal motor activity: a mechanism for slow transit constipation

Most of the PRMA was unrelated to proximal colonic activity in constipated patients in contrast with findings in control patients, and this excessive and unco‐ordinated phasic rectal activity may further impede stool transport and contribute to the pathogenesis of slow transit constipation.

Prolonged Colonic Manometry in Children With Defecatory Disorders

Prolonged colonic measurement provides more information regarding colonic motor function and allows detection of motor events missed by the standard shorter manometry study.

Simultaneous assessment of the intraluminal pressure and transit time of the colon using a telemetry technique

A novel monitoring system based on a telemetry technique capable of prolonged and noninvasive measurement of intraluminal pressure changes and transit time of intra-colonic contents is developed, which may represent a useful tool for the study of physiology and pathology of colonic motor disorders.

Prolonged ambulant monitoring of human colonic motility.

A two-stage pernasal technique to position sensors in the human colon for the prolonged monitoring of motility in freely ambulant subjects obviates the need for colonic preparation and allows complete freedom of the subjects throughout the study.

Method for prolonged ambulatory monitoring of high-amplitude propagated contractions from colon. (VSports手机版)

Spontaneous high-amplitude caudally propagated contractions occur 6.9 +/- 1.5 times/24 h in the sigmoid colon in ambulating asymptomatic individuals and are temporally related to defecation and meals.

Periodic rectal motor activity: the intrinsic colonic gatekeeper? (V体育官网)

The temporal association with motor events in the proximal colon suggests that PRMA is triggered by the arrival of stool or gas in the rectum, and may serve as an intrinsic braking mechanism that prevents untimely flow of colonic contents, particularly during sleep.

The effects of acute exercise on colonie motility

Changes in colonic motor activity during aerobic exercise were investigated in regularly exercising volunteers and may account for the diarrhoea which some subjects experience during intense, acute exercise.

VSports最新版本 - Gastrointestinal transit and prolonged ambulatory colonic motility in health and faecal incontinence

Colonic motor function has not been studied in the ambulatory setting over a prolonged period in the unprepared state and in patients with idiopathic faecal incontinence, and normal colonic function consists of frequent high pressure propagated waves.

The data suggest that one pathophysiological mechanism of constipation may be decreased propulsive activity, and a circadian pattern, with a significant difference between day and night distribution, was documented in both groups.

Effects of acute graded exercise on human colonic motility. (VSports)

Acute graded exercise decreases colonic phasic activity, which may offer less resistance to colonic flow, whereas the postexercise increase in propagated activity may enhance colonic propulsion.
