Ventral 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] |
Colorectal Surgery
Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. The field is also known as proctology, but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular. The word ''proctology'' is derived from the Greek words , meaning "anus" or "hindparts", and , meaning "science" or "study". Physicians specializing in this field of medicine are called colorectal surgeons or proctologists. In the United States, to become colorectal surgeons, surgical doctors have to complete a general surgery residency as well as a colorectal surgery fellowship, upon which they are eligible to be certified in their field of expertise by the American Board of Colon and Rectal Surgery or the American Osteopathic Board of Proctology. In other countries, certification to practice proctology is given to surgeons at the end of a 2–3 year subspecialty residency by the country's ...

Colectomy
Colectomy (''wikt:colo-#Prefix, col-'' + ''wikt:-ectomy#Suffix, -ectomy'') is the surgical removal of any extent of the Large intestine#Structure, colon, the longest portion of the large bowel. Colectomy may be performed for prophylactic, curative, or palliative reasons. Indications include cancer, infection, infarction, perforation, and impaired function of the colon. Colectomy may be performed Laparotomy, open, Laparoscopy, laparoscopically, or Robot-assisted surgery, robotically. Following removal of the bowel segment, the surgeon may restore continuity of the bowel or create a colostomy. Partial or subtotal colectomy refers to removing a portion of the colon, while total colectomy involves the removal of the entire colon. Complications of colectomy include anastomotic leak, bleeding, infection, and damage to surrounding structures. Indications Common indications for colectomy include: * Colon cancer, Colorectal cancer * Colorectal polyp, Colon polyps not amenable to removal b ...

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] |
Rectal Discharge
Rectal discharge is intermittent or continuous expression of liquid from the anus ( per rectum). Normal rectal mucus is needed for proper excretion of waste. Otherwise, this is closely related to types of fecal incontinence (e.g., fecal leakage) but the term rectal discharge does not necessarily imply degrees of incontinence. Types of fecal incontinence that produce a liquid leakage could be thought of as a type of rectal discharge. Types Different types of discharge are described. Generally "rectal discharge" refers to either a mucous or purulent discharge, but, depending upon what definition of rectal discharge is used, the following could be included: * Purulent rectal discharge * Mucous rectal discharge (mucorrhea) * Watery rectal discharge * Steatorrhoea ("fatty diarrhea" caused by excess fat in stools, or an oily anal leakage) * Keriorrhea (orange oily anal leakage caused by high levels of escolar and oilfish in the diet) * Rectal bleeding, melena and hematochezia * Fe ...

Fecal Incontinence
Fecal incontinence (FI), or in some forms, encopresis, is a lack of control over defecation, leading to involuntary loss of bowel contents—including flatus (gas), liquid stool elements and mucus, or solid feces. 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 incontinence usually results from a deficiency of multiple mechanisms. The most common causes are thought to be immediate or delayed damage from childbirth, complications from prior anorectal surgery (especially involving the anal sphincters or hemorrhoidal vascular cushions), altered bowel habits (e.g., caused by irritable bowel syndrome, Crohn's disease, ulcerative colitis, food intolerance, or constipation with overflow incontinence). Reported prevalence figures vary: an estimated 2.2% of community-dwelling adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochrane (organisation)
Cochrane is a British international charitable organisation formed to synthesize medical research findings to facilitate evidence-based choices about health interventions involving health professionals, patients and policy makers. It includes 53 review groups that are based at research institutions worldwide. Cochrane has over volunteer experts from around the world. The group conducts systematic reviews of healthcare interventions and diagnostic tests and publishes them in the Cochrane Library. While Cochrane reviews typically focus on randomized controlled trials, some reviews, particularly in areas such as public and occupational health, also incorporate other study designs. These may include non-randomised observational studies as well as controlled before–after (CBA) studies and interrupted time-series studies. According to the Library, articles are available via one-click access, though some may require registration or a subscription. History Cochrane, prev ...

US Food And Drug Administration
The United States Food and Drug Administration (FDA or US FDA) is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed and veterinary products. The FDA's primary focus is enforcement of the Federal Food, Drug, and Cosmetic Act (FD&C). However, the agency also enforces other laws, notably Section 361 of the Public Health Service Act as well as associated regulations. Much of this regulatory-enforcement work is not directly related to food or drugs but involves other factors like regulating lasers, cellular phones, and condoms. In addition, the FDA takes control of diseases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress Urinary Incontinence
Stress incontinence, also known as stress urinary incontinence (SUI) or effort incontinence is a form of urinary incontinence. It is due to inadequate closure of the bladder outlet by the urethral sphincter. Pathophysiology Stress incontinence is the loss of small amounts of urine associated with coughing, laughing, sneezing, exercising or other movements that increase intra-abdominal pressure and thus increasing the pressure on the bladder. The urethra is normally supported by fascia and muscles of the pelvic floor. If this support is insufficient due to any reason, the urethra would not close properly at times of increased abdominal pressure, allowing urine to pass involuntarily. Most lab results such as urine analysis, cystometry and post-void residual volume are normal. Some sources distinguish between urethral hypermobility and intrinsic sphincter deficiency. The latter is more rare, and requires different surgical approaches. Men Stress incontinence in men is most co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelvic Organ Prolapse
Pelvic organ prolapse (POP) is characterized by descent of pelvic organs from their normal positions into the vagina. In women, the condition usually occurs when the pelvic floor collapses after gynecological cancer treatment, childbirth or heavy lifting. Injury incurred to fascia membranes and other connective structures can result in cystocele, rectocele or both. Treatment can involve dietary and lifestyle changes, physical therapy, or surgery. Types * Anterior vaginal wall prolapse ** Cystocele (bladder into vagina) ** Urethrocele (urethra into vagina) ** Cystourethrocele (both bladder and urethra) * Posterior vaginal wall prolapse ** Enterocele (small intestine into vagina) ** Rectocele (rectum into vagina) ** Sigmoidocele * Apical vaginal prolapse ** Uterine prolapse (uterus into vagina) ** Vaginal vault prolapse (descent of the roof of vagina) – after surgical removal of the uterus hysterectomy Grading Pelvic organ prolapses are graded either via the Baden–Walker ...

Stapled Trans-anal Rectal Resection
Stapled trans-anal rectal resection (STARR) is a minimally invasive surgical procedure for conditions such as obstructed defecation syndrome, internal rectal prolapse, and rectocele. Circular surgical staplers are used to resect (remove) sections of the wall of the rectum via the anus. The defects are then closed with surgical staples. A modification of the technique is Contour Transtar. The average age of patients undergoing STARR is about 55 years, and 83% of procedures are carried out on females. The procedure is controversial. The results of many thousands of STARR procedures have been published in research. Proponents state that the procedure is simple, minimally invasive, safe, and effective. Skeptics argue that the complications may be significant ( fecal urgency, urge fecal incontinence) or rarely even life-threatening. There is a general trend away from STARR towards ventral rectopexy for surgical treatment of obstructed defecation syndrome. Indications Surgery may b ...

Pouch Of Douglas
The rectouterine pouch (rectovaginal pouch, pouch of Douglas or cul-de-sac) is the extension of the peritoneum into the space between the posterior wall of the uterus and the rectum in the human female. Structure In women, the rectouterine pouch is the deepest point of the peritoneal cavity. It is posterior to the uterus, and anterior to the rectum. Its anterior boundary is formed by the posterior fornix of the vagina. The pouch on the other side of the uterus near to the anterior fornix is the vesicouterine pouch. After passing over the fundus of the uterus, the peritoneum extends inferiorly along the entire posterior aspect of the uterus, reaching the posterior vaginal wall before reflecting superior-ward onto the anterior aspect of the rectal ampulla (i.e. the inferior portion of the rectum). In men, the region corresponding to the rectouterine pouch is the rectovesical pouch, which lies between the urinary bladder and rectum. Peritoneal fluid It is normal to have appr ...
