Radiographic examination of the process of defecation after the instillation of a CONTRAST MEDIA into the rectum.
Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.
Herniation of the RECTUM into the VAGINA.
Protrusion of tissue, structure, or part of an organ through the bone, muscular tissue, or the membrane by which it is normally contained. Hernia may involve tissues such as the ABDOMINAL WALL or the respiratory DIAPHRAGM. Hernias may be internal, external, congenital, or acquired.
The normal process of elimination of fecal material from the RECTUM.
A sac or recess formed by a fold of the peritoneum.
A form of intestinal obstruction caused by the PROLAPSE of a part of the intestine into the adjoining intestinal lumen. There are four types: colic, involving segments of the LARGE INTESTINE; enteric, involving only the SMALL INTESTINE; ileocecal, in which the ILEOCECAL VALVE prolapses into the CECUM, drawing the ILEUM along with it; and ileocolic, in which the ileum prolapses through the ileocecal valve into the COLON.
Soft tissue formed mainly by the pelvic diaphragm, which is composed of the two levator ani and two coccygeus muscles. The pelvic diaphragm lies just below the pelvic aperture (outlet) and separates the pelvic cavity from the PERINEUM. It extends between the PUBIC BONE anteriorly and the COCCYX posteriorly.
Infrequent or difficult evacuation of FECES. These symptoms are associated with a variety of causes, including low DIETARY FIBER intake, emotional or nervous disturbances, systemic and structural disorders, drug-induced aggravation, and infections.
The terminal segment of the LARGE INTESTINE, beginning from the ampulla of the RECTUM and ending at the anus.
The distal segment of the LARGE INTESTINE, between the SIGMOID COLON and the ANAL CANAL.
Failure of voluntary control of the anal sphincters, with involuntary passage of feces and flatus.

Colonic transit time and rectoanal videomanometry in Parkinson's disease. (1/32)

BACKGROUND: Constipation is a prominent lower gastrointestinal tract dysfunction that occurs frequently in Parkinson's disease (PD). OBJECTIVE: To investigate colonic transport and dynamic rectoanal behaviour during filling and defecation in patients with PD. METHODS: Colonic transit time (CTT) and rectoanal videomanometry analyses were performed in 12 patients with PD (10 men and 2 women; mean age, 68 years, mean duration of disease, five years; mean Hoehn and Yahr grade, 3; decreased stool frequency (<3 times a week) in six, difficulty in stool expulsion in eight) and 10 age matched normal control subjects (7 men and 3 women; mean age, 62 years; decreased stool frequency in two, difficulty in stool expulsion in two). RESULTS: In the PD patients, CTT was significantly prolonged in the rectosigmoid segment (p<0.05) and total colon (p<0.01) compared with the control subjects. At the resting state, anal closure and squeeze pressures of PD patients were lower than those in control subjects, though not statistically significant. However, the PD patients showed a smaller increase in abdominal pressure on coughing (p<0.01) and straining (p<0.01). The sphincter motor unit potentials of the patients were normal. During filling, PD patients showed normal rectal volumes at first sensation and maximum desire to defecate, and normal rectal compliance. However, they showed smaller amplitude in phasic rectal contraction (p<0.05), which was accompanied by an increase in anal pressure that normally decreased, together with leaking in two patients. During defecation, most PD patients could not defecate completely with larger post-defecation residuals (p<0.01). PD patients had weak abdominal strain and smaller rectal contraction on defecation than those in control subjects, though these differences were not statistically significant. However, the PD patients had larger anal contraction on defecation (p<0.05), evidence of paradoxical sphincter contraction on defecation (PSD). CONCLUSIONS: Slow colonic transit, decreased phasic rectal contraction, weak abdominal strain, and PSD were all features in our PD patients with frequent constipation.  (+info)

Defecography in symptomatic older women living at home. (2/32)

BACKGROUND: complaints of defecation disorders in older patients living at home is an emerging problem. Little is known about radiological examination of this population. OBJECTIVE: this study aimed to analyse the yield of defecography in women older than 75 years, living at home and complaining of defecation disorders. DESIGN AND SETTINGS: prospective study of patients referred to a radiology department in a tertiary-care medical centre in Rouen, France. SUBJECTS AND METHODS: 52 women (mean age: 78, range: 75-93) complaining of constipation, faecal incontinence or pelvic pain underwent defecography. Defecography was performed after intake of a barium meal and vaginal opacification. Radiographs were analysed accordingly with the established criteria. RESULTS: defecography showed perineal descent in 27 patients, rectocele in 29, intussusception in 33 and enterocele in 14. A combination of abnormalities was found in 40 women. Only 3 studies were normal. There was no significant association between symptoms and pelvic disorders revealed by defecography. CONCLUSIONS: defecography in symptomatic women aged 75 years and over did not raise any technical difficulty. It revealed a 77% rate of abnormalities, but there was no relationship between the symptoms and the detected abnormalities.  (+info)

Infliximab in refractory pouchitis complicated by fistulae following ileo-anal pouch for ulcerative colitis. (3/32)

AIM: To determine the efficacy of infliximab in the treatment of chronic refractory pouchitis complicated by fistulae following ileal pouch-anal anastomosis for ulcerative colitis. METHODS: This open study included seven patients (four females, three males) with chronic refractory pouchitis complicated by fistulae. Pouchitis was diagnosed by clinical, endoscopic and histological criteria. The sites of the fistulae were as follows: pouch-bladder in one, vaginal in three, perianal in two, and both vaginal and perianal in one. Extra-intestinal manifestations (erythema nodosum, arthralgia) were present in four patients. Crohn's disease was carefully excluded in all patients after re-evaluation of the history, re-examination of the original proctocolectomy specimen and examination of the proximal small bowel. All patients had been treated with antibiotics and three with steroids. Patients received infliximab, 5 mg/kg, at 0, 2 and 6 weeks. Azathioprine (2.5 mg/kg) was also started for all patients as bridge therapy. Clinical response was classified as complete, partial or no response. Fistulae closure was classified as complete (cessation of fistulae drainage and total closure of all fistulae), partial (a reduction in the number, size, drainage or discomfort associated with fistulae) or no closure. The pouchitis disease activity index and quality of life were also used as outcome measures. RESULTS: Clinically, all patients improved. At the 10-week follow-up, six of the seven patients had a complete clinical response, and five had complete fistulae closure. At the 10-week follow-up, the median pouchitis disease activity index decreased from 12 (baseline) (range, 10-15) to 5 (range, 3-8); the median quality of life decreased from 37 points (range, 33-40) to 14 (range, 9-18). Erythema nodosum and arthralgia showed complete remission soon after the first infusion of infliximab. CONCLUSIONS: These preliminary results indicate that infliximab may be recommended for the treatment of refractory pouchitis complicated by fistulae following ileal pouch-anal anastomosis for ulcerative colitis.  (+info)

Rectal sensorimotor dysfunction in patients with urge faecal incontinence: evidence from prolonged manometric studies. (4/32)

BACKGROUND AND AIMS: Although external anal sphincter dysfunction is the major cause of urge faecal incontinence, approximately 50% of such patients have evidence of rectal hypersensitivity and report exaggerated stool frequency and urgency. The contribution of rectosigmoid contractile activity to the pathophysiology of this condition is unclear, and thus the relations between symptoms, rectal sensation, and rectosigmoid motor function were investigated. METHODS: Fifty two consecutive patients with urge faecal incontinence, referred to a tertiary surgical centre, and 24 volunteers, underwent comprehensive anorectal physiological investigation, including prolonged rectosigmoid manometry. Patients were classified on the basis of balloon distension thresholds into those with rectal hypersensitivity (n = 27) and those with normal rectal sensation (n = 25). Automated quantitative analysis of overall rectosigmoid contractile activities and, specifically, high amplitude contractions and rectal motor complex activity was performed. RESULTS: External anal sphincter dysfunction was similar in both patient groups. Overall, phasic activity and high amplitude contraction frequency were greater, and rectal motor complex variables significantly altered, in those with rectal hypersensitivity. Symptoms, more prevalent in the rectal hypersensitivity group, were also more often associated with rectosigmoid contractile events. For individuals, reduced compliance and increased rectal motor complex frequency were only observed in patients with rectal hypersensitivity. CONCLUSIONS: We have identified a subset of patients with urge faecal incontinence-namely, those with rectal hypersensitivity-who demonstrated increased symptoms, enhanced perception, reduced compliance, and exaggerated rectosigmoid motor activity. Comprehensive assessment of rectosigmoid sensorimotor function, in addition to evaluation of anal function, should be considered in the investigation of patients with urge faecal incontinence.  (+info)

Computerized videodefecography versus defecography: do we need radiographs? (5/32)

CONTEXT AND OBJECTIVE: Defecography has been recognized as a valuable method for evaluating patients with evacuation disorders. It consists of the use of static radiography and fluoroscopy to record different situations within anorectal dynamics. Conventionally, rectal parameters are measured using radiograms. It is rare for fluoroscopy alone to be used. Computer software has been developed with the specific aim of calculating these measurements from digitized videotaped images obtained during fluoroscopy, without the need for radiographic film, thereby developing a computerized videodefecography method. The objective was thus to compare measurements obtained via computerized videodefecography with conventional measurements and to discuss the advantages of the new method. DESIGN AND SETTING: Prospective study at the radiology service of Hospital das Clinicas, Universidade de Sao Paulo. METHOD: Ten consecutive normal subjects underwent videodefecography. The anorectal angle, anorectal junction, puborectalis muscle length, anal canal length and degree of anal relaxation were obtained via the conventional method (using radiography film) and via computerized videodefecography using the ANGDIST software. Measurement and analysis of these parameters was performed by two independent physicians. RESULTS: Statistical analysis confirmed that the measurements obtained through direct radiography film assessment and using digital image analysis (computerized videodefecography) were equivalent. CONCLUSIONS: Computerized videodefecography is equivalent to the traditional defecography examination. It has the advantage of offering reduced radiation exposure through saving on the use of radiography.  (+info)

Dynamic MR imaging of outlet obstruction. (6/32)

The outlet obstruction syndrome encompasses all pelvic floor abnormalities which are responsible for an incomplete evacuation of fecal contents from the rectum. It has been estimated that outlet obstruction may be observed in half of constipated patients. A detailed clinical examination still represents the cornerstone of the diagnosis of these patients. However, there is general agreement that a reliable evaluation of the different pelvic floor abnormalities and the treatment decision highly depend on the imaging assessment. Traditionally, conventional defecography has played an important role in the radiological assessment of these patients but the technique is limited by its projectional nature and its inability to detect soft-tissue structures. Dynamic pelvic MR imaging using either closed-configuration or open-configuration MR systems is a rapidly evolving technique which has been gaining increased interest over the last years. The free selection of imaging planes, the good temporal resolution, and the excellent soft-tissue contrast have transformed this method into the preferred imaging modality in the evaluation of patients with pelvic floor dysfunction including rectocele, enterocele, internal rectal prolapse, and anismus.  (+info)

Posterior pelvic floor disorders: a prospective comparison using introital ultrasound and colpocystodefecography. (8/32)

OBJECTIVE: To compare introital ultrasound with colpocystodefecography (CCD) in quantifying the anorectal angle and in the diagnosis of posterior pelvic floor disorders. METHODS: Forty-three consecutive women with functional impairment of the posterior pelvic floor were enrolled after a clinical evaluation. Using both CCD and introital ultrasound examination, the anorectal angle was measured during squeezing to evaluate the strength of voluntary muscle contraction and during straining to assess pelvic floor relaxation. Rectocele depth and the presence of intussusception were assessed. The performance of CCD and that of introital ultrasound were compared. RESULTS: Good concordance was obtained between introital ultrasound and CCD. The intraclass correlation coefficient was 0.82 (95% CI, 0.69-0.89) for measurement of the anorectal angle during squeezing and 0.67 (95% CI, 0.47-0.81) during straining. Rectoceles > 4 cm on CCD were detected by introital ultrasound in 100% of cases, and there was 91% agreement for rectal intussusception. Cohen's kappa index was moderate for rectocele assessment (0.41, P < 0.01) and excellent for intussusception (0.91, P < 0.001). It was also noted that introital ultrasound could be used to detect pelvic floor dyssynergia. CONCLUSIONS: Introital ultrasound is a simple, accurate, non-invasive method with which to assess anorectal dynamics.  (+info)

Defecography is a medical diagnostic procedure that involves taking X-ray images of the rectum and anus while a person is defecating. Also known as evacuation proctography, this test assesses how well the muscles and structures of the pelvic floor perform during a bowel movement. It can help identify issues such as rectal prolapse, intussusception, or abnormalities in muscle function that may be causing difficulties with defecation or fecal incontinence.

During the procedure, the individual is usually given an enema containing a contrast material, which makes the contents of the rectum visible on X-ray images. The person then sits on a special toilet seat placed within the X-ray machine, and is asked to strain and evacuate as if having a bowel movement. Fluoroscopic X-ray imaging is used to capture real-time images of the pelvic floor and surrounding structures during this process. The resulting images can help healthcare providers diagnose and treat various anorectal conditions.

Rectal prolapse is a medical condition where the rectum, which is the lower end of the colon, slips outside the anus, the opening through which stool leaves the body. This usually occurs due to weakened muscles and supporting structures in the pelvic area, often as a result of aging, childbirth, or long-term constipation or diarrhea.

The rectal prolapse can be partial, where only a small portion of the rectum slips outside the anus, or complete, where the entire rectum protrudes. This condition can cause discomfort, pain, bleeding, and difficulty with bowel movements. Treatment options may include dietary changes, medication, or surgical intervention.

A rectocele is a type of pelvic organ prolapse, which occurs when the rectum (the lower end of the colon) bulges into the back wall of the vagina. This condition most commonly affects women who have gone through childbirth, although it can also occur in older women or those with long-term constipation or other conditions that put pressure on the pelvic floor muscles.

Rectoceles can cause a variety of symptoms, including difficulty having bowel movements, feeling like something is sticking out of the vagina, and pain during sexual intercourse. In some cases, rectoceles may not cause any symptoms at all. Treatment options for rectoceles include pelvic floor physical therapy, lifestyle changes (such as avoiding heavy lifting or straining), and in severe cases, surgery.

The exact medical definition of a rectocele is: "A herniation of the rectal wall into the vaginal wall, often associated with disruption of the rectovaginal septum." This means that there is a protrusion or bulge of the rectal wall into the vaginal wall, which can be caused by a weakening or tearing of the tissue that separates the two structures.

A hernia is a protrusion of an organ or tissue through a weakened area in the abdominal wall, often appearing as a bulge beneath the skin. This condition can occur in various parts of the body such as the groin (inguinal hernia), navel (umbilical hernia), or site of a previous surgical incision (incisional hernia). Hernias may cause discomfort or pain, especially when straining, lifting heavy objects, or during bowel movements. In some cases, they may lead to serious complications like intestinal obstruction or strangulation, requiring immediate medical attention.

Defecation is the medical term for the act of passing stools (feces) through the anus. It is a normal bodily function that involves the contraction of muscles in the colon and anal sphincter to release waste from the body. Defecation is usually a regular and daily occurrence, with the frequency varying from person to person.

The stool is made up of undigested food, bacteria, and other waste products that are eliminated from the body through the rectum and anus. The process of defecation is controlled by the autonomic nervous system, which regulates involuntary bodily functions such as heart rate and digestion.

Difficulties with defecation can occur due to various medical conditions, including constipation, irritable bowel syndrome, and inflammatory bowel disease. These conditions can cause symptoms such as hard or painful stools, straining during bowel movements, and a feeling of incomplete evacuation. If you are experiencing any problems with defecation, it is important to speak with your healthcare provider for proper diagnosis and treatment.

The Douglas pouch, also known as the recto-uterine pouch or cul-de-sac of Douglas, is a potential space within the female pelvic cavity. It is located between the posterior wall of the uterus and the anterior wall of the rectum. This space can be examined during a gynecological examination, such as a transvaginal ultrasound or during surgery, to assess for any abnormalities or pathologies that may be present in this area.

Intussusception is a medical condition in which a part of the intestine telescopes into an adjacent section, leading to bowel obstruction and reduced blood flow. It often affects children under 3 years old but can also occur in adults. If not treated promptly, it can result in serious complications such as perforation, peritonitis, or even death. The exact cause is usually unknown, but it may be associated with infections, intestinal disorders, or tumors.

The pelvic floor is a group of muscles, ligaments, and connective tissues that form a sling or hammock across the bottom of the pelvis. It supports the organs in the pelvic cavity, including the bladder, rectum, and uterus or prostate. The pelvic floor helps control urination, defecation, and sexual function by relaxing and contracting to allow for the release of waste and during sexual activity. It also contributes to postural stability and balance. Weakness or damage to the pelvic floor can lead to various health issues such as incontinence, pelvic organ prolapse, and sexual dysfunction.

Constipation is a condition characterized by infrequent bowel movements or difficulty in passing stools that are often hard and dry. The medical definition of constipation varies, but it is generally defined as having fewer than three bowel movements in a week. In addition to infrequent bowel movements, other symptoms of constipation can include straining during bowel movements, feeling like you haven't completely evacuated your bowels, and experiencing hard or lumpy stools.

Constipation can have many causes, including a low-fiber diet, dehydration, certain medications, lack of physical activity, and underlying medical conditions such as irritable bowel syndrome or hypothyroidism. In most cases, constipation can be treated with lifestyle changes, such as increasing fiber intake, drinking more water, and getting regular exercise. However, if constipation is severe, persistent, or accompanied by other symptoms, it's important to seek medical attention to rule out any underlying conditions that may require treatment.

The anal canal is the terminal portion of the digestive tract, located between the rectum and the anus. It is a short tube-like structure that is about 1 to 1.5 inches long in adults. The main function of the anal canal is to provide a seal for the elimination of feces from the body while also preventing the leakage of intestinal contents.

The inner lining of the anal canal is called the mucosa, which is kept moist by the production of mucus. The walls of the anal canal contain specialized muscles that help control the passage of stool during bowel movements. These muscles include the internal and external sphincters, which work together to maintain continence and allow for the voluntary release of feces.

The anal canal is an important part of the digestive system and plays a critical role in maintaining bowel function and overall health.

The rectum is the lower end of the digestive tract, located between the sigmoid colon and the anus. It serves as a storage area for feces before they are eliminated from the body. The rectum is about 12 cm long in adults and is surrounded by layers of muscle that help control defecation. The mucous membrane lining the rectum allows for the detection of stool, which triggers the reflex to have a bowel movement.

Fecal incontinence is the involuntary loss or leakage of stool (feces) from the rectum. It is also known as bowel incontinence. This condition can range from occasional leakage of stool when passing gas to a complete loss of bowel control. Fecal incontinence can be an embarrassing and distressing problem, but there are treatments available that can help improve symptoms and quality of life.

The causes of fecal incontinence can vary, but some common factors include:

* Damage to the muscles or nerves that control bowel function, such as from childbirth, surgery, spinal cord injury, or long-term constipation or diarrhea.
* Chronic digestive conditions, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or celiac disease.
* Neurological conditions, such as multiple sclerosis, stroke, or spina bifida.
* Aging, which can lead to a decrease in muscle strength and control.

Treatment for fecal incontinence depends on the underlying cause of the condition. Treatments may include:

* Bowel training exercises to improve muscle strength and control.
* Changes in diet to help regulate bowel movements.
* Medications to treat constipation or diarrhea.
* Surgery to repair damaged muscles or nerves, or to create a new opening for stool to exit the body.

If you are experiencing symptoms of fecal incontinence, it is important to speak with your healthcare provider. They can help determine the cause of your symptoms and develop an appropriate treatment plan.
