Some diseases, such as [[Chagas disease]], [[Hirschsprung's disease]] and others provoke the destruction of the [[autonomic nervous system]] inside the colon's [[mucosa]] ([[Auerbach's plexus]]) and may cause extremely large (giant) fecalomas, which must be surgically removed (disimpaction).

Overview

A fecaloma is a hardening of feces into stones of varying size inside the colon.

Pathophysiology

A fecaloma occurs in the setting of chronic obstruction of fecal transit.

Causes

Natural History, Complications and Prognosis

Fecal impaction may have severe and even lethal effects, such as the rupture of the colon's walls by acute angles of the fecalomas (stercoral perforation), followed by septicemia. A fecolith is also usually the cause of acute appendicitis.[1]

Treatment

Extremely large (giant) fecalomas, which must be surgically removed (disimpaction). Normally, however, fecalomas can be manually disimpacted or by passing colonic tubes (catheters which carry a flow of disimpaction fluid (solvent).
