Adenocarcinoma with colon obstruction and rupture

If you were to have advanced adenocarcinoma followed by a colon obstruction and subsequent rupture in the small intestine, approximately  how long would it normally take for the blood supply to be cut off from the lower bowel?   Would you be able to still have a bowel movement and if so in what approximate time frame following the occurence of the ruptured small intestine?  Following the rupture,  what likelihood that the following bowel movement would be extra large, or formed?  How much more likely would it be diarrhea or even a smear?

There's no way to really answer this. It would be pure speculation on our part to try to 'think it through' because there are many, many factors that feed into it. Furthermore, why would the blood supply be cut off from the lower bowel? Cancers typically secrete chemicals that upregulate blood into the area of the cancer. Typically the way you'd get a blood supply decrease is if someone had ischemic problems via the arterial supply into the bowel.

A rupture of the small intestine would suggest someone would end up with an infection process that would mean fever and a fair amount of pain.
