A fecaloma is a buildup of thickened, stone-like feces in
the colon or rectum of various sizes that gives the
appearance of a tumor in the belly. The colon is the
major part of the large intestine, which is located in the
belly. The intestine is a tube shaped structure that is
part of the digestive tract. The rectum is the last part of
the large intestine. Fecalomas occur when there is a
chronic (long-term) blockage of movement through the
intestines (e.g., chronic constipation). Another example
of chronic blockage in the intestine is megacolon, which
is abnormal widening of the colon often accompanied
by cessation of movement s in the intestine.

Some fecalomas can become very large and need to be surgically removed, which is
known as disimpaction. One condition that can cause this is Chagas disease, which is a
type of parasite disease. A parasite is an organism that lives in or on another organism
to obtain nourishment. Another condition that can cause fecalomas is Hirschsprung's
disease, which is a disorder of the abdomen when all or part of the large intestine or
parts of the gastrointestinal tract are without nerves, which prevents them from
functioning.  These conditions and others can cause harm to the automomic nervous
system. The autonomic nervous system is an extensive network in the body (with
connections to the spinal cord) that is important for involuntary bodily functions that are
necessary to maintain life, such as respiration (breathing) and heart rate.

"Where Medical Information is Easy to Understand"™
Although it does not happen often, fecalomas can form around
hairballs or other materials that have been shed by the intestine or
which attract and hold water and cause a state of dryness. Some
fecalomas can be removed by a finger probe (from a doctor of other
health care provider) or through use of a catheter that follows the
flow of fluid (e.g., water, lubricants, or solvent). A catheter is a
flexible, hollow tube that is inserted into an opening of the body,
blood vessel, or duct in the body, with the main purpose of allowing
fluids, gas, or surgical instruments to pass from or into these areas.
A solvent is a usually liquid substance (such as water) that is
capable of dissolving or dispersing one or more substances.

Fecalomas and attempts to remove them can have serious and sometimes deadly consequences such as
a tearing or rupture of the intestinal wall by the catheter. If the infection becomes severe, this can be
followed by infection and sepsis. Sepsis is a possibly deadly medical condition characterized by
inflammation of the body. A small fecoloma can sometimes cause acute (sudden) diverticulitis and
appendicitis. Diverticulitis is the formation of pouches in the wall of the intestine. Appendicitis is
inflammation of the appendix. Fecaloma is also known as coproma, coprolith,  fecolith, fecalith, fecal
tumor, scatoma, and stercoroma. Fecaloma comes from the Latin word “faeces” meaning “feces” and the
Greek word “oma” meaning “tumor.” Put the words together and you get “feces tumor.”
