What happens during a total pancreatectomy with islet autotransplantation (TP-IAT)?

Physicians describe what is involved in having a total pancreatectomy with islet autotransplantation (TP-IAT) and what the potential health outcomes are for patients post-surgery. They explain how TPIAT is the most complex pancreatic operation offered, entailing the removal of the pancreas, and the isolation and injection of specialized islet cells that produce insulin. In over 90% of children that undergo a TP-IAT, the main outcome is relief from debilitating pain, freedom from opioid reliance, and overall improvement in quality of life.

No info about the survival rate of adults ? Specially the elderly! Of course 90% of children will survive. They are young and strong. Like I said. No info about the survival rates of adults. Apparently only 20% of adult patients are alive at the 5yr post operative period.
