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]
A fecalith is a stone made of feces. It is a hardening of feces into lumps of varying size and may occur anywhere in the intestinal tract but is typically found in the colon. It is also called appendicolith when it occurs in the appendix and is sometimes concurrent with appendicitis. [1] They can also obstruct diverticula.
The rectum now contracts and shortens in peristaltic waves, thus forcing fecal material out of the rectum, through the anal canal and out of the anus. The internal and external anal sphincters along with the puborectalis muscle allow the feces to be passed by pulling the anus up over the exiting feces in shortening and contracting actions.
In both groups rectal urge volume increased after long term use of transanal irrigation. The researchers suggested that patients get accustomed to larger rectal volumes, and without the irrigation their everyday sensation of urge from the presence of stool in the rectum is decreased. This may encourage patients to continue using the irrigation.
The anal sphincter muscles then push the stool out of the anus in a controlled way, says De Latour. Sometimes, the bowel movement we sense coming isn’t poop at all — it’s gas.
A large volume or high enema [50] can be given to cleanse as much of the colon as possible of feces, [51] [52] and the solution administered commonly contains castile soap which irritates the colon's lining resulting in increased urgency to defecate. [53] However, a low enema is generally useful only for stool in the rectum, not in the ...
Studies have found that prunes and other dried fruits increase stool frequency and reduce the risk of constipation. Prunes can be consumed whole or as a juice. Prunes can be consumed whole or as a ...
The rectum shortens as material is forced into the anal canal and peristaltic waves push the feces out of the rectum. The internal and external anal sphincters along with the puborectalis muscle allow the feces to be passed by muscles pulling the anus up over the exiting feces. [3]
