fecal impaction


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

fecal

 [fe´k'l]
pertaining to or of the nature of feces.
fecal impaction accumulation of putty-like or hardened feces in the rectum or sigmoid. The condition often occurs in patients with long-standing bowel problems and chronic constipation. It also may develop when barium is introduced into the intestinal tract and not completely removed.

Symptoms include painful defecation, feeling of fullness in the rectum, and constipation or a diarrheic stool. Rectal examination reveals a hard or putty-like mass. The condition can be prevented in most cases by adequate removal of barium after radiologic studies, and by careful monitoring of the bowel movements of patients with problems of bowel elimination.

Fecal impaction usually requires digital removal with a gloved finger to break up the mass. Prior to removal the patient may be given an oil retention enema to help soften the mass.
