The Physiology of Human Defecation
Digestive Diseases and Sciences, 2012Human defecation involves integrated and coordinated sensorimotor functions, orchestrated by central, spinal, peripheral (somatic and visceral), and enteric neural activities, acting on a morphologically intact gastrointestinal tract (including the final common path, the pelvic floor, and anal sphincters). The multiple factors that ultimately result in

Imaging of obstructed defecation
Clinical Radiology, 2008Constipation is a common problem in the western world, which occurs as a consequence of impaired colonic transit and/or due to obstructed defecation. Imaging plays an important role in distinguishing structural from functional causes of constipation.

AbstractObstructed defecation is one of the causes of chronic constipation. Clinical tests suggest that patients with obstructed defecation have impaired pelvic floor function. Appropriate management relies on proper identification of the underlying pathophysiology.

Gastroenterology Clinics of North America, 2001
Dyssynergic defecation is a common clinical problem that affects half of patients with chronic constipation. In many patients, there is a significant overlap with slow transit constipation. The chief underlying pathophysiologic mechanism is a failure of rectoanal coordination.

Pediatrics, 1988
To the Editor.— The recent article by Loening-Baucke et al helps our understanding of defecation dynamics. However, her recommendation that "children with encopresis should have their rectal sensation and their ability to defecate balloons evaluated" (p 678) seems like diagnostic overkill. 1.

In-Utero Defecation: Fact or Fiction?
European Journal of Pediatric Surgery, 1999An experimental study was performed to investigate the gastrointestinal motility and in-utero defecation by radionuclide techniques. Forty-eight New-Zealand white rabbit fetuses at 25 days' gestation (fullterm, 31 to 32 days) were divided into two groups as A (n: 24) and B (n: 24).

Infrequent Defecation in Children
JAMA: The Journal of the American Medical Association, 1987To the Editor.— I am writing in reference to the question concerning infrequent defecation or Hirschsprung's disease and the reply to it by Dr Kirschner in the Jan 23/30, 1987, issue of JAMA . 1 There are several points stated, implied, or omitted that should upset any physician caring for children.

Defecation-induced bronchospasm
The Journal of Emergency Medicine, 2000Acute asthma exacerbations are common. Patients with asthma experience symptoms in response to a wide variety of stimuli, and identifying the precipitating cause may be useful in guiding treatment and preventing future attacks. A case of asthma exacerbation occurring during multiple defecations is reported.

Defecation is a reflex provoked through a sacral arc by distention of the rectum. In infancy, the evacuation of the rectum occurs reflexly. The development of the control over defecation reflex is associated with the growth of inhibition over it. The cerebral cortex cannot only inhibit the reflex but can also initiate it when suitable circumstances are
