At the University of Chicago, our specialized surgery department allows us to be one of a select number of hospitals in the country who are currently running a clinical trial for islet transplantation. Islet transplantation is a promising treatment for Type 1 diabetes because surgery is not needed. The islet cells from a deceased donor's pancreas are removed and injected into a major blood vessel of the patient's liver. The islet cells then begin making insulin. Islet transplantation aims to allow patients to live an insulin-free lifestyle.
