Paradoxical anal contraction during attempted defecation in constipated patients was first described in a paper in 1985, when the term anismus was first used. [40] The researchers drew analogies to a condition called vaginismus, which involves paroxysmal (sudden and short lasting) contraction of pubococcygeus (another muscle of the pelvic floor ...
A fecal impaction or an impacted bowel is a solid, immobile bulk of feces that can develop in the rectum as a result of chronic constipation [1] (a related term is fecal loading which refers to a large volume of stool in the rectum of any consistency). [2]
The gastrointestinal tract (GI tract) has a complex control mechanism that relies on coordinated interaction between muscular contractions and neuronal impulses (nerve signals). [3] Fecal incontinence or constipation occurs when there is a problem with normal bowel functioning. This could be for a variety of reasons.
Biofeedback has been shown to improve symptoms (improved frequency of bowel movements, reduced straining) and also reduce need for laxatives, [16] and patients stop needing to self-digitate. [24] Biofeedback can successfully treat abnormal contraction and relaxation of muscles in the anorectum during defecation. [ 24 ]
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 ...
There are many different types of rectal discharge, but the most common presentation of a discharge is passage of mucus or pus wrapped around an otherwise normal bowel movement. [10] Rectal discharge has many causes, and may present with other symptoms: [10] [11] Staining of undergarments; Constant feeling of dampness around anus
Fecal vomiting occurs when the bowel is obstructed for some reason, and intestinal contents cannot move normally. Peristaltic waves occur in an attempt to decompress the intestine, and the strong contractions of the intestinal muscles push the contents backwards through the pyloric sphincter into the stomach, where they are then vomited. [3]
Tenesmus is characterized by a sensation of needing to pass stool, accompanied by pain, cramping, and straining. Despite straining, little stool is passed. [3] Tenesmus is generally associated with inflammatory diseases of the bowel, which may be caused by either infectious or noninfectious conditions.
