Maroon skin or hair seen in stool

The clinical manifestations of intestinal ileus are similar to those of gallstone ileus. Partial obstruction usually begins, and complete bowel obstruction can occur when the intestinal stones move down to the end of the small ileum with small bowel cavity. Therefore, the obstruction site is also more common in the terminal ileum, and a few cases can be found in the duodenum, colon, and rectum. Gastrointestinal bleeding can occur when the intestinal stones are torn or compressed and the intestinal mucosa is necrotic. Can also cause intestinal torsion, intestinal wall necrosis, perforation and the formation of diffuse peritonitis. Maroon skin or hair can sometimes be seen in vomit or feces.
