Obstructed defecation syndrome (abbreviated as ODS, with many synonymous terms) is a major cause of functional constipation (primary constipation), [19] of which it is considered a subtype. [20] 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 ...
Many authors describe an "obstructed defecation syndrome", of which anismus is a cause. [24] The Rome II classification functional defecation disorders were divided into 3 types, [25] however the symptoms the patient experiences are identical. [26] Type I: paradoxical contraction of the pelvic floor muscles during attempted defecation
Obstructed defecation syndrome. [3] It has been suggested that a sigmoidocele does not cause obstruction, but rather is a compensatory mechanism which increases rectal pressure and helps evacuation in the presence of excessive perineal descent. [6] Incomplete evacuation of rectal contents. [7] Bulge in posterior (back) wall of vagina. [1]
Solitary rectal ulcer syndrome (SRUS or SRU) is a chronic disorder of the rectal mucosa (the lining of the rectum). [1] Symptoms are variable. There may be bleeding, obstructed defecation, or no symptoms at all. Very often but not always SRUS occurs in association with varying degrees of rectal prolapse.
This is a feature of people with soiling secondary to obstructed defecation. [26] Obstructed defecation is often due to anismus (paradoxical contraction or relaxation failure of the puborectalis). [ 2 ] : 38 Whilst anismus is largely a functional disorder , organic pathologic lesions may mechanically interfere with rectal evacuation.
Constipation also has neurological causes, including anismus, descending perineum syndrome, desmosis and Hirschsprung's disease. [7] In infants, Hirschsprung's disease is the most common medical disorder associated with constipation. Anismus occurs in a small minority of persons with chronic constipation or obstructed defecation. [33]
[11] [12] If they cause inflammation, chronic use of suppositories may cause rectal stricture, [2] but overall this is a safe method of drug delivery. [13] Thermal burns are possible if hot water enemas are attempted by patients or practitioners of alternative medicine in the belief that they will provide a stronger stimulus for evacuation of ...
Digital evacuation, or, manual pushing, on the posterior wall of the vagina helps to aid in bowel movement in a majority of cases of rectocele. Rectocele can be a cause of symptoms of obstructed defecation. [3]
