Enterocele
An enterocele is a herniation of a peritoneum-lined sac containing small intestine through the pelvic floor, between the rectum and the vagina (in females). Enterocele is significantly more common in females, especially after hysterectomy. It has been suggested that the terms enterocele and sigmoidocele are inaccurate, since hernias are usually named according to location and not according to contents. However, the terms are in widespread use. As such, enterocele, peritoneocele, sigmoidocele, and omentocele could be considered as types of cul-de-sac hernia. Classification * Posterior enterocele (develops in the rectovaginal space, also termed the pouch of Douglas or the cul-de-sac). * Anterior enterocele (develops in the vesicovaginal space). ** Retains the full thickness of the anterior vaginal wall. ** Lacks vaginal wall (or very thin and ulcerated vaginal wall). Anterior enterocele is rare. It may occur after cystectomy or hysterectomy. In these cases, the anterior wall of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obstructed Defecation
Obstructed defecation syndrome (abbreviated as ODS, with many synonymous terms) is a major cause of functional constipation (primary constipation), of which it is considered a subtype. It is characterized by difficult and/or incomplete emptying of the rectum with or without an actual reduction in the number of bowel movements per week. Normal definitions of functional constipation include infrequent bowel movements and hard stools. In contrast, ODS may occur with frequent bowel movements and even with soft stools, and the colonic transit time may be normal (unlike slow transit constipation), but delayed in the rectum and sigmoid colon. Definitions and terminology Definition and classification of constipation Constipation is usually divided into two groups: primary and secondary. Primary constipation is caused by disrupted regulation of neuromuscular function of in the colon and the rectum, and also disruption of brain–gut neuroenteric function. Secondary constipation is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defecography
Defecography (also known as proctography, defecating/defecation proctography, evacuating/evacuation proctography or dynamic rectal examination) 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. History Defecating proctography was pioneered in 1945, during World War II. The procedure gained popularity at this time in the midst of an outbreak of whipworm, which is known to cause rectal prolapse. It has since become used for diagnosis of various anorectal disorders, including anismus and other causes of obstructed defecation. It has fallen out of favor due to inadequate training in the technique. It is now only performed at a few institutions. Many radiology residents refer to the procedure as the "Def Proc", "Defogram", or "Stool Finale". Indications Defecography may be i ...

Cystocele
A cystocele, also known as a prolapsed bladder, is a medical condition in which a woman's bladder bulges into her vagina. Some may have no symptoms. Others may have trouble starting urination, urinary incontinence, or frequent urination. Complications may include recurrent urinary tract infections and urinary retention. Cystocele and a prolapsed urethra often occur together and is called a cystourethrocele. Cystocele can negatively affect quality of life. Causes include childbirth, constipation, chronic cough, heavy lifting, hysterectomy, genetics, and being overweight. The underlying mechanism involves weakening of muscles and connective tissue between the bladder and vagina. Diagnosis is often based on symptoms and examination. If the cystocele causes few symptoms, avoiding heavy lifting or straining may be all that is recommended. In those with more significant symptoms a vaginal pessary, pelvic muscle exercises, or surgery may be recommended. The type of surgery typical ...

Ventral Mesh Rectopexy
Ventral rectopexy is a surgical procedure for external rectal prolapse, internal rectal prolapse (rectal intussusception), and sometimes other conditions such as rectocele, obstructed defecation syndrome, or solitary rectal ulcer syndrome. The rectum is fixed into the desired position, usually using a biological or synthetic mesh which is attached to the sacral promontory. The effect of the procedure is correction of the abnormal descended position of the posterior compartment of the pelvis (i.e., the rectum), reinforcement of the anterior (front) surface of the rectum, and elevation of the pelvic floor. In females, the rectal-vaginal septum is reinforced, and there may be an opportunity to simultaneously correct any prolapse of the middle compartment (i.e., the uterus). In such cases, ventral rectopexy may be combined with sacrocolpopexy. The surgery is usually performed laparoscopically (via small openings made in the abdomen). Background There are over 300 different variations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelvic Floor
The pelvic floor or pelvic diaphragm is an anatomical location in the human body which has an important role in urinary and anal continence, sexual function, and support of the pelvic organs. The pelvic floor includes muscles, both skeletal and smooth, ligaments, and fascia and separates between the pelvic cavity from above, and the perineum from below. It is formed by the levator ani, levator ani muscle and coccygeus muscle, and associated connective tissue. The pelvic floor has two hiatus (anatomy), hiatuses (gaps): (anteriorly) the urogenital hiatus through which urethra and vagina pass, and (posteriorly) the rectal hiatus through which the anal canal passes. Structure Definition Some sources do not consider "pelvic floor" and "pelvic diaphragm" to be identical, with the "diaphragm" consisting of only the levator ani and coccygeus, while the "floor" also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Rectal Prolapse
Internal rectal prolapse (IRP) is medical condition involving a telescopic, funnel-shaped infolding of the wall of the rectum that occurs during defecation. The term IRP is used when the prolapsed section of rectal wall remains inside the body and is not visible outside the body. IRP is a type of rectal prolapse. The other main types of rectal prolapse are external rectal prolapse (where the prolapsed segment of rectum protrudes through the anus and is visible externally) and rectal mucosal prolapse (where only the mucosal layer of the wall of the rectum prolapses). IRP may not cause any symptoms, or may cause obstructed defecation syndrome (difficulty during defecation) and/or fecal incontinence. The causes are not clear. IRP may represent the first stage of a progressive condition that eventually may result in external rectal prolapse. However, it is uncommon for IRP to progress to external rectal prolapse. It is possible that chronic straining during defecation (dyssynergic def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colporrhaphy
Colporrhaphy (also vaginal wall repair, anterior and/or posterior colporrhaphy, anterior and/or posterior vaginal wall repair, or simply A/P repair or A&P repair) is a surgical procedure in women that repairs a defect in the wall of the vagina. It is the surgical intervention for both cystocele (protrusion of the urinary bladder into the vagina) and rectocele (protrusion of the rectum The rectum (: rectums or recta) is the final straight portion of the large intestine in humans and some other mammals, and the gut in others. Before expulsion through the anus or cloaca, the rectum stores the feces temporarily. The adult ... into the vagina). The repair may be to either or both of the anterior (front) or posterior (rear) vaginal walls, thus the origin of some of its alternative names. References {{reflist Gynecological surgery ...

External Rectal Prolapse
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of 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 whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved. Rectal prolapse may occur without any symptoms, but depending upon the nature of the prolapse there may be mucous discharge (mucus coming from the anus), rectal bleeding, degrees of fecal incontinence, and obstructed defecation symptoms. Rectal prolapse is generally more common in elderly women, although it may occur at any age and in either sex. It is very rarely life-threatening, but the symptoms can be debilitating if left untreated. Most external prolapse cases can be treated successfully, often with a surgical procedure. Internal prolapses are traditionally harder to treat and surgery may not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocontrast Agent
Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray-based imaging techniques such as computed tomography (contrast CT), projectional radiography, and fluoroscopy. Radiocontrast agents are typically iodine, or more rarely barium sulfate. The contrast agents absorb external X-rays, resulting in decreased exposure on the X-ray detector. This is different from radiopharmaceuticals used in nuclear medicine which emit radiation. Magnetic resonance imaging (MRI) functions through different principles and thus MRI contrast agents have a different mode of action. These compounds work by altering the magnetic properties of nearby hydrogen nuclei. Types and uses Radiocontrast agents used in X-ray examinations can be grouped in positive (iodinated agents, barium sulfate), and negative agents (air, carbon dioxide, methylcellulose). Iodine (circulatory system) Iodinated contrast contains iodine. It is the main type of radiocontrast used for intra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
