Stercoral perforation is the perforation or rupture of the intestine‘s walls by its internal contents, such as foreign objects, or, more commonly, by hardened feces (fecalomas) which may form in long constipations or other diseases which cause obstruction of transit, such as Chagas disease, Hirschprung’s disease, toxic colitis and megacolon.

Stercoral perforation is a very dangerous, life-threatening situation, as well as a surgical emergency, because the spillage of contaminated intestinal contents into the abdominal cavity leads to peritonitis a rapid bacteremia (bacterial infection of the blood), with many complications.
