Why do we never hear about people getting sepsis from hemorrhoids or anal fissures?

Given the various bacteria in human fecal matter.

Hemorrhoids are dilated veins in the rectum area. They are not ruptured or exposed directly to the gut flora as there will be skin barrier (endothelium/epithelium) separating the venous system from the rectum. 

Anal fissures do have a break in the skin so there is a potential for infection, and likely there will be inflammation there. But, our body is fairly good at keeping the bacteria out of the body unless you have other disease processes like IBD, cancer, or previous infections.
