Build up of stool in the rectum or colon, forming a compact mass that can obstruct the intestine.
It is due to the slowing of intestinal transit caused by age, physical inactivity, the intake of foods rich in fibre and dehydration. Medicines like opioids can promote it as well.
The most common symptoms include scanty, hard stools, abdominal pain and a feeling of abdominal fullness.
Diagnosis is clinical, through questioning and physical examination, although a simple X-ray or CT-scan may be necessary in the most doubtful cases.
Initially, treatment should be conservative with digestive rest, laxative intake and enemas. If the fecalith persists, a digital or endoscopic extraction may be necessary. The most severe cases may require surgery, to avoid an occlusion with intestinal perforation. A correct daily intake of water and fibre in the daily diet, as well as regular physical exercise, is essential for its prevention.
