  eMedicine - Rectal Prolapse : Article by Lynn K Flowers
In children, rectal prolapse is probably related to certain anatomical features such as the vertical orientation of the rectum, mobility of the sigmoid colon, relative weakness of the pelvic floor muscle, mucosa poorly fixed to submucosa, and redundant rectal mucosa.
Rectal prolapse is usually only a symptom, and evaluation should focus on discovery of an underlying disorder.
Rectal prolapse in children is usually a benign condition that needs evaluation for the underlying condition.

  Information on Rectal Prolapse - Medicine Online Medical Encyclopedia
Rectal prolapse is similar to, but not the same as, rectocele, which is a common condition in women.
This stage of rectal prolapse is called mucosal prolapse, or partial prolapse, meaning that only the inner lining of the rectum (rectal mucosa) protrudes from the anus.
Rectal prolapse is caused by weakening of the ligaments and muscles that hold the rectum in place.

 Solitary Rectal Ulcer Syndrome-Mucosal Prolapse
The anterior rectal mucosa is frequently forced into the anal canal and as a consequence becomes strangulated, causing congestion, edema, and ulceration.
Rectal prolapse and solitary rectal ulcer syndrome are both benign conditions affecting the rectum, mainly in women; prolapse tends to occur late in life, while solitary rectal ulcer syndrome has a predilection for the younger adult.
Solitary rectal ulcer syndrome is essentially due to prolapse and traumatization of the rectal mucosa.

Rectal prolapse in children is a self-limiting disease and usually responds to conservative measures.
The mucosa is then dissected from the underlying muscle coat as a sleeve until the apex of the prolapse is reached, and the dissection is carried on down into the prolapse as far as possible (Fig.

 Rectal Prolapse - New Treatments, May 2, 2007
Rectal prolapse is likely an expression of aberrant physiological forces that cause the loss of natural anatomic relationships.
In early stages, rectal prolapse may be difficult to diagnose; it may occur only when the patient is seated on the toilet and straining, and it may be difficult to reproduce these conditions during an examination in the prone jackknife or left lateral examining positions.
The cause of recurrent rectal prolapse is not clear, but is presumed to be the same as the causative factors of the original prolapse.

 Rectal Prolapse
Rectal prolapse is an eversion of several layers of the rectum through the anus caused by persistent straining because of urogenital or intestinal disease.
In addition, with rectal prolapse, a lubricated probe cannot be passed between the rectal wall and the prolapsed mass.
The mucosa should be gently manipulated and massaged in an attempt to remove edema from the prolapsed segment.

 Rectal prolapse - Wikipedia, the free encyclopedia
Rectal prolapse normally describes a medical condition wherein the walls of the rectum protrude through the anus and hence become visible outside the body.
The slang term "pink sock" is used to refer to when the rectum is pulled out during anal sex due to a variety of factors including insufficient lubrication and a much larger than average diameter penis.
The condition undergoes progression: beginning with prolapsation during bowel movements, through Valsalva movements (sneezing and so forth), then through daily activities such as walking until finally it may become chronic and cease to retract.

Rectal prolapse is a condition in which the rectum falls downwards and turns inside out.
There are two types of rectal prolapse: 1) incomplete - involving only the rectal mucosa, and 2) complete - involving both the rectal mucosa and the rectal wall - this is also called a procidentia.
Rectal prolapse is most often a chronic condition, and can usually be reduced with the patient recumbent with gentle manual pressure.

 eMedicine - Rectal Prolapse : Article by Lisa S Poritz, MD
Patients with rectal prolapse and constipation often have a redundant colon, and resection of it is thought to improve constipation and cure rectal prolapse.
In an anterior resection for rectal prolapse, the rectum is mobilized to the level of the lateral ligaments, and the redundant colon (sigmoid) is resected.
A circumferential incision is made through the mucosa of the prolapsed rectum near the dentate line; using electrocautery, the mucosa is stripped from the rectum to the apex of the prolapse and excised (see Image 3).

 2004 Gastrointestinal Pathology Specialty Conference Handout - Case 3
Characteristic histologic findings include: hypertrophic, disorganized muscularis mucosae with bundles of smooth muscle and collagen extending into the superficial lamina propria around crypts; diffuse fibrosis of the lamina propria; distortion of crypt architecture; crypt and surface epithelium that is often hyperplastic or shows regenerative atypia; and erosions with or without adherent exudates.
The mucosal prolapse that occurs during excessive straining with defecation is seen as an attempt to overcome an abnormality of the pelvic floor musculature during defecation, namely, inappropriate contraction of the puborectalis muscle and the external anal sphincter instead of relaxation.
Repeated trauma of the prolapsing mucosa against the contracting puborectalis muscle and mucosal ischemia due to the high intrarectal pressures necessary for voiding act together to cause mucosal damage and eventual ulceration.

A new study examines the protein synthetic rates as an indicator of potential tissue proliferation in grossly normal rectal mucosa derived from cancer-bearing subjects and compares this rate to the mucosa from subjects after tumor removal.
This study is believed to be the first to demonstrate in situ that mucosa from subjects after tumor removal demonstrates a significantly lower rate of protein synthesis than does macroscopically normal colorectal mucosa in patients with sporadic colorectal cancer.

 Higher Levels of HIV in Rectal Secretions Among MSM
The observation that ART has an independent effect on HIV RNA in seminal plasma but not in rectal mucosal secretions, relative to blood plasma, may be due to differential levels of antiretroviral drugs or to anatomic and immunologic differences in the male genital tract versus rectal mucosa...
Factors that influence rectal HIV shedding and infectiousness may differ from cofactors that affect seminal HIV levels, given the abundance of activated rectal lymphocytes and the absence, in the intestinal tract, of a immunologic equivalent to the blood-testes barrier.
This effect of study location on rectal HIV RNA levels was not explained by the friability of rectal mucosa on examination, frequency of receptive anal intercourse, or condom or lubricant use with anal intercourse (data not shown).

If the specific symptoms such as rectal or anal pain, burning and itching, have occurred as well as any history of bright red rectal bleeding, an anoscopic exam should be performed with a standard metal anoscope or even the clear disposable ones.
In general, rectal mucosa is pale, pink in color, with a background of blood vessels, which are finely arborized with side branching of vessels.

 Effects of Ascorbic Acid on Rectal Polyps:Familial Polyposis
Exposure of the rectal mucosa to ileal contents appears to be a prerequisite for spontaneous regression because adenomatous polyps disappear only in the rectum and not in otherwise defunctionalized colon in familial polyposis.
Other reasons for selection of patients with ileorectal anastomoses were that a rapid intestinal transit time provided more intensive exposure of rectal mucosa to the reducing agent, the entire remaining target mucosa was accessible to periodic direct surveillance, and a larger number of polyps permitted better quantitation of response.
To the extent that the likelihood of developing rectal cancer is related to the presence and number of polyps in the retained rectum, the important issue from our studies is the possibility of reducing the risk of cancer.
