In the early 19th century, James O'Beirne proposed that a physiologically important sphincter existed at the rectosigmoid junction. Interest in the rectosigmoid junction had been stirred by a common affliction of the time: spasmodic constriction of the rectum. It was believed that many patients suffered from chronic constipation because of rectosigmoid spasms. O'Beirne proposed that a sphincter at the rectosigmoid junction governed the passage of stool from the sigmoid into the rectum. Further, he maintained that spasmodic constriction of the rectum resulted from dysfunction of this rectosigmoid sphincter.

In the early 19th century, James O'Beirne proposed that a physiologically important sphincter existed at the rectosigmoid junction. Interest in the rectosigmoid junction had been stirred by a common affliction of the time: spasmodic constriction of the rectum.

It was believed that many patients suffered from chronic constipation because of rectosigmoid spasms. O'Beirne proposed that a sphincter at the rectosigmoid junction governed the passage of stool from the sigmoid into the rectum.

Further, he maintained that spasmodic constriction of the rectum resulted from dysfunction of this rectosigmoid sphincter. His views, however, conflicted with those of such contemporaries as Houston, who emphasized the role of rectal valves in producing spasmodic constriction. Anatomic studies in the early 20th century found at least a rudimentary sphincter at the rectosigmoid junction in 40 percent of the normal population.

Motility studies in the last 35 years have demonstrated unique intraluminal pressure patterns as well as the propagation of retroperistaltic waves in this area. The rectosigmoid in patients with constipation shows an increased activity, as if this area is causing a physiologic obstruction to the passage of stool into the rectum. In contrast, the rectosigmoid in patients with diarrhea demonstrates markedly decreased activity, thereby providing unobstructed access of the feces to the rectum.

These studies support O'Beirne's hypothesis that a sphincter governs the passage of stool from the sigmoid colon into the rectum.

Anismus is the failure of the normal relaxation of pelvic floor muscles during attempted defecation. It can be caused by physical defects or it can occur for other reasons or unknown reasons.

Anismus that has a behavioral cause could be viewed as having similarities with parcopresis , or psychogenic fecal retention. Symptoms include tenesmus the sensation of incomplete emptying of the rectum after defecation has occurred and constipation.

Retention of stool may result in fecal loading retention of a mass of stool of any consistency or fecal impaction retention of a mass of hard stool. Liquid stool may leak around a fecal impaction, possibly causing degrees of liquid fecal incontinence. This is usually termed encopresis or soiling in children, and fecal leakage , soiling or liquid fecal incontinence in adults. Anismus is usually treated with dietary adjustments, such as dietary fiber supplementation. It can also be treated with a type of biofeedback therapy, during which a sensor probe is inserted into the person's anal canal in order to record the pressures exerted by the pelvic floor muscles.

These pressures are visually fed back to the patient via a monitor who can regain the normal coordinated movement of the muscles after a few sessions.

Some researchers have suggested that anismus is an over-diagnosed condition, since the standard investigations or digital rectal examination and anorectal manometry were shown to cause paradoxical sphincter contraction in healthy controls, who did not have constipation or incontinence. These researchers went on to conclude that paradoxical pelvic floor contraction is a common finding in healthy people as well as in people with chronic constipation and stool incontinence, and it represents a non-specific finding or laboratory artifact related to untoward conditions during examination, and that true anismus is actually rare.

To understand the cause of anismus, an understanding of normal colorectal anatomy and physiology, including the normal defecation mechanism, is helpful. The relevant anatomy includes: the rectum , the anal canal and the muscles of the pelvic floor , especially puborectalis and the external anal sphincter.

The rectum is a section of bowel situated just above the anal canal and distal to the sigmoid colon of the large intestine. It is believed to act as a reservoir to store stool until it fills past a certain volume, at which time the defecation reflexes are stimulated. In continent individuals, the rectum can expand to a degree to accommodate this function.

The anal canal is the short straight section of bowel between the rectum and the anus. It can be defined functionally as the distance between the anorectal ring and the end of the internal anal sphincter. The internal anal sphincter forms the walls of the anal canal. The internal anal sphincter is not under voluntary control, and in normal persons it is contracted at all times except when there is a need to defecate. The internal sphincter is responsible for creating a watertight seal, and therefore provides continence of liquid stool elements.

The puborectalis muscle is one of the pelvic floor muscles. It is skeletal muscle and is therefore under voluntary control. The puborectalis originates on the posterior aspect of the pubic bone , and runs backwards, looping around the bowel. The point at which the rectum joins the anal canal is known as the anorectal ring, which is at the level that the puborectalis muscle loops around the bowel from in front.

This arrangement means that when puborectalis is contracted, it pulls the junction of the rectum and the anal canal forwards, creating an angle in the bowel called the anorectal angle. This angle prevents the movement of stool stored in the rectum moving into the anal canal. It is thought to be responsible for gross continence of solid stool. Conversely, relaxation of the puborectalis reduces the pull on the junction of the rectum and the anal canal, causing the anorectal angle to straighten out.

A squatting posture is also known to straighten the anorectal angle, meaning that less effort is required to defecate when in this position. Distension of the rectum normally causes the internal anal sphincter to relax rectoanal inhibitory response, RAIR and the external anal sphincter initially to contract rectoanal excitatory reflex, RAER. The relaxation of the internal anal sphincter is an involuntary response. The external anal sphincter, by contrast, is made up of skeletal or striated muscle and is therefore under voluntary control.

It can contract vigorously for a short time. Contraction of the external sphincter can defer defecation for a time by pushing stool from the anal canal back into the rectum. Once the voluntary signal to defecate is sent back from the brain, the abdominal muscles contract straining causing the intra-abdominal pressure to increase. The rectum now contracts and shortens in peristaltic waves , thus forcing fecal material out of the rectum, through the anal canal and out of the anus. The internal and external anal sphincters along with the puborectalis muscle allow the feces to be passed by pulling the anus up over the exiting feces in shortening and contracting actions.

In patients with anismus, the puborectalis and the external anal sphincter muscles fail to relax, with resultant failure of the anorectal angle to straighten out and facilitate evacuation of feces from the rectum.

As these muscles are under voluntary control, the failure of muscular relaxation or paradoxical contraction that is characteristic of anismus can be thought of as either maladaptive behavior or a loss of voluntary control of these muscles. Anismus could be thought of as the patient "forgetting" how to push correctly, i. It may be that this scenario develops due to stress.

For example, one study reported that anismus was strongly associated with sexual abuse in women. In many cases however, the underlying pathophysiology in patients presenting with obstructed defecation cannot be determined. Some authors have commented that the "puborectalis paradox" and "spastic pelvic floor" concepts have no objective data to support their validity.

Persistent failure to fully evacuate stool may lead to retention of a mass of stool in the rectum fecal loading , which can become hardened, forming a fecal impaction or even fecoliths. When anismus occurs in the context of intractable encopresis as it often does , resolution of anismus may be insufficient to resolve encopresis. The walls of the rectum may become stretched, known as megarectum.

The Rome classification diagnostic criteria for functional defecation disorders is as follows: [22]. The Rome criteria recommend that anorectal testing is not usually indicated in patients with symptoms until patients have failed conservative treatment e. Physical examination can rule out anismus by identifying another cause but is not sufficient to diagnose anismus. The measurement of pressures within the rectum and anus with a manometer pressure-sensing probe.

Anismus is classified as a functional defecation disorder. It is also a type of rectal outlet obstruction a functional outlet obstruction. Where anismus causes constipation, it is an example of functional constipation. Some authors describe an " obstructed defecation syndrome ", of which anismus is a cause. The Rome classification subdivides functional defecation disorders into 3 types, [22] however the symptoms the patient experiences are identical. It can be seen from the above classification that many of the terms that have been used interchangeably with anismus are inappropriately specific and neglect the concept of impaired propulsion.

Similarly, some of the definitions that have been offered are also too restrictive. Other techniques include manometry , balloon expulsion test , evacuation proctography see defecating proctogram , and MRI defecography. Initial steps to alleviate anismus include dietary adjustments and simple adjustments when attempting to defecate. Treatments for anismus include biofeedback retraining, botox injections, and surgical resection. Anismus sometimes occurs together with other conditions that limit see contraindication the choice of treatments.

Biofeedback training for treatment of anismus is highly effective and considered the gold standard therapy by many. Injections of botulin toxin type-A into the puborectalis muscle are very effective in the short term, and somewhat effective in the long term. Historically, the standard treatment was surgical resection of the puborectalis muscle, which sometimes resulted in fecal incontinence. Recently, partial resection partial division has been reported to be effective in some cases. Paradoxical anal contraction during attempted defecation in constipated patients was first described in a paper in , when the term anismus was first used.

However, the term anismus implies a psychogenic etiology, which is not true although psychological dysfunction has been described in these patients. Many terms have been used synonymously to refer to this condition, some inappropriately. The term "anismus" has been criticised as it implies a psychogenic cause.
