What is the mortality rate for the bcir operation?

Depends! It's going to depend on your surgeon's expertise, the hospital you choose, your disease state, your current anatomy, your surgical history, other major health issues (like kidney, heart, lung or liver disease), the medications you take (eg immunosuppressants). In general, i would imagine death to be less than 1 in a 100. You should consult with an expert: http://www.Fascrs.Org/.
Depends. Risks of mortality from major abdominal surgery generally are very low, but it primarily depends on one's overalll health, medical risks & if there is any history of heart or lung diseases. Continent ileostomy surgery would have more morbidity risks such as infections or pouch complications & the expected mortality very low.
