Levator ani syndrome is a condition characterized by brief intermittent burning pain or tenesmus of the rectal or perineal area, [1] caused by spasm of the levator ani muscle. [2] [3] [4] The genesis of the syndrome is unknown; however, inflammation of the arcus tendon is a possible cause of levator ani syndrome. [5]

Signs and symptoms

Symptoms include a dull ache more often to the left 2 inches above the anus or higher in the rectum and a feeling of constant rectal pressure or burning. The pain may last for 30 minutes or longer, and is usually described as chronic or intermittent with prolonged periods, in contrast to the brief pain of the related disorder proctalgia fugax. Pain may be worse when sitting than when standing or lying. [6] Precipitating factors include extended sitting, defecation, stress, sexual intercourse, childbirth, and surgery. Palpation of the levator ani muscle may find tenderness. [7]

Cause

Levator ani syndrome is characterized by painful spasm of the levator ani muscle. [2] [3] [4]

The genesis of the syndrome is unknown, however it has been suggested that inflammation of the arcus tendon is the possible cause of levator ani syndrome. [5] Proctalgia fugax and levator ani syndrome have not been found to be of psychosomatic origin, although stressful events may trigger attacks. [3] Occurrence of levator ani syndrome is associated with "significant elevations on the hypochondriasis, depression, and hysteria scales of the Minnesota Multiphasic Personality Inventory," which is also the case in general among chronic pain sufferers. [4]

Diagnosis

The diagnosis of levator ani syndrome is clinical, based on the pattern of signs and symptoms. The diagnosis does not require any routine imaging or additional testing, though other causes of rectal pain must be excluded. Suspected levator ani syndrome is confirmed in the presence of chronic or recurrent rectal pain, occurring in episodes that last at least 30 minutes, with tenderness with posterior traction of the puborectalis muscle.[ citation needed ]

Treatment

The discomfort may be relieved by walking or pelvic relaxation techniques. Other treatments include massage of the muscle, warm baths, muscle relaxant medications such as cyclobenzaprine, therapeutic ultrasound and biofeedback. Electrical stimulation of the levator ani muscle has been used to try to break the spastic cycle. Injection of botulinum toxin A has also been used.[ citation needed ]

Interstitial cystitis Medical condition

Interstitial cystitis (IC), also known as bladder pain syndrome (BPS), is a type of chronic pain that affects the bladder and pelvic floor. Together with CP/CPPS, it makes up urologic chronic pelvic pain syndrome (UCPPS). Symptoms include feeling the need to urinate right away, needing to urinate often, and pain with sex. IC/BPS is associated with depression and lower quality of life. Many of those affected also have irritable bowel syndrome and fibromyalgia.

Constipation Bowel dysfunction that is characterized by infrequent or difficult evacuation of feces

Constipation refers to bowel movements that are infrequent or hard to pass. The stool is often hard and dry. Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. Complications from constipation may include hemorrhoids, anal fissure or fecal impaction. The normal frequency of bowel movements in adults is between three per day and three per week. Babies often have three to four bowel movements per day while young children typically have two to three per day.

Fecal incontinence Inability to refrain from defecation

Fecal incontinence (FI), or in some forms encopresis, is a lack of control over defecation, leading to involuntary loss of bowel contents, both liquid stool elements and mucus, or solid feces. When this loss includes flatus (gas) it is referred to as anal incontinence. FI is a sign or a symptom, not a diagnosis. Incontinence can result from different causes and might occur with either constipation or diarrhea. Continence is maintained by several interrelated factors, including the anal sampling mechanism, and usually there is more than one deficiency of these mechanisms for incontinence to develop. The most common causes are thought to be immediate or delayed damage from childbirth, complications from prior anorectal surgery, altered bowel habits, and receptive anal sex. An estimated 2.2% of community dwelling adults are affected. However, reported prevalence figures vary. A prevalence of 8.39% among non-institutionalized U.S adults between 2005 and 2010 has been reported and among institutionalized elders figures come close to 50%.

Levator ani Broad, thin muscle group, situated on either side of the pelvis

The levator ani is a broad, thin muscle group, situated on either side of the pelvis. It is formed from three muscle components: the pubococcygeus, the iliococcygeus, and the puborectalis.

De Quervain syndrome Medical condition

De Quervain syndrome is inflammation of two tendons that control movement of the thumb and their tendon sheath. This results in pain at the outside of the wrist. Pain is typically increased with gripping or rotating the wrist. The thumb may also be difficult to move smoothly. Onset of symptoms is gradual.

Dyspareunia is painful sexual intercourse due to medical or psychological causes. The pain can primarily be on the external surface of the genitalia, or deeper in the pelvis upon deep pressure against the cervix. Medically, dyspareunia is a pelvic floor dysfunction and affects up to 53% of adult women at some point in their lives, although it is frequently under diagnosed. It can affect a small portion of the vulva or vagina or be felt all over the surface. Understanding the duration, location, and nature of the pain is important in identifying the causes of the pain.

Rectal prolapse Medical condition

Rectal prolapse is when the rectal walls have prolapsed to a degree where they protrude out the anus and are visible outside the body. However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on if the prolapsed section is visible externally, and if the full or only partial thickness of the rectal wall is involved.

Pelvic floor Anatomical structure

The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus muscle, and associated connective tissue which span the area underneath the pelvis. The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. The pelvic floor separates the pelvic cavity above from the perineal region below. Both males and females have a pelvic floor. To accommodate the birth canal, a female's pelvic cavity is larger than a male's.

Functional gastrointestinal disorders (FGID), also known as disorders of gut–brain interaction, include a number of separate idiopathic disorders which affect different parts of the gastrointestinal tract and involve visceral hypersensitivity and motility disturbances.

Anal fistula Disease of the anus

Anal fistula is a chronic abnormal communication between the epithelialised surface of the anal canal and usually the perianal skin. An anal fistula can be described as a narrow tunnel with its internal opening in the anal canal and its external opening in the skin near the anus. Anal fistulae commonly occur in people with a history of anal abscesses. They can form when anal abscesses do not heal properly.

Proctalgia fugax, a variant of levator ani syndrome, is a severe, episodic pain in the regions of the rectum and anus. It can be caused by cramping of the levator ani muscle, particularly in the pubococcygeal part.

Anorectal abscess Medical condition

Anorectal abscess is an abscess adjacent to the anus. Most cases of perianal abscesses are sporadic, though there are certain situations which elevate the risk for developing the disease, such as diabetes mellitus, Crohn's disease, chronic corticosteroid treatment and others. It arises as a complication of paraproctitis. Ischiorectal, inter- and intrasphincteric abscesses have been described.

Defecography

Defecography is a type of medical radiological imaging in which the mechanics of a patient's defecation are visualized in real time using a fluoroscope. The anatomy and function of the anorectum and pelvic floor can be dynamically studied at various stages during defecation.

Rectal pain is the symptom of pain in the area of the rectum. A number of different causes (68) have been documented.

Anismus Medical condition

Anismus is the failure of normal relaxation of pelvic floor muscles during attempted defecation. It can occur in both children and adults, and in both men and women. 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.

Descending perineum syndrome refers to a condition where the perineum "balloons" several centimeters below the bony outlet of the pelvis during strain, although this descent may happen without straining. The syndrome was first described in 1966 by Parks et al.

Dyssynergia is any disturbance of muscular coordination, resulting in uncoordinated and abrupt movements. This is also an aspect of ataxia. It is typical for dyssynergic patients to split a movement into several smaller movements. Types of dyssynergia include Ramsay Hunt syndrome type 1, bladder sphincter dyssynergia, and anal sphincter dyssynergia.

Vaginal support structures

The vaginal support structures are those muscles, bones, ligaments, tendons, membranes and fascia, of the pelvic floor that maintain the position of the vagina within the pelvic cavity and allow the normal functioning of the vagina and other reproductive structures in the female. Defects or injuries to these support structures in the pelvic floor leads to pelvic organ prolapse. Anatomical and congenital variations of vaginal support structures can predispose a woman to further dysfunction and prolapse later in life. The urethra is part of the anterior wall of the vagina and damage to the support structures there can lead to incontinence and urinary retention.

Hard flaccid syndrome Medical condition

Hard flaccid syndrome (HFS), also known as hard flaccid (HF), is a chronic painful condition characterized by a semi-rigid penis at the flaccid state, a soft glans at the erect state, pelvic pain, low libido, erectile dysfunction, erectile pain, pain on ejaculation, penile sensory changes, lower urinary tract symptoms, contraction of the pelvic floor muscles, and psychological distress. Other complaints include rectal and perineal discomfort, cold hands and feet, and a hollow or detached feeling inside the penile shaft. The majority of HFS patients are in their 20s–30s and symptoms significantly affect one's quality of life.
