Expanding the indications of pancreas transplantation alone.

Objectives: Total pancreatectomy (TP) is associated with postoperative endocrine and exocrine insufficiency. Especially, insulin therapy reduces quality of life and may lead to long-term complications. We review the literature with regard to the potential option of pancreas transplantation alone (PTA) after TP in patients with chronic pancreatitis or benign tumors.

Methods: A MEDLINE search (1958-2013) using the terminologies pancreas transplantation, pancreas transplantation alone, total pancreatectomy, morbidity, mortality, insulin therapy, and quality of life was performed. In addition, the current book and congress publications were reviewed.

Results: Total pancreatectomy after benign and borderline tumors as well as chronic pancreatitis is continuously increasing. Despite improvement of exogenous insulin therapy, more than 50% of these patients experience severe glucose control problems, which cause up to 50% long-term mortality. Pancreas transplantation alone can cure both endocrine and exocrine insufficiency and reduce the associated risks. The 3-year graft and patient survival rates after PTA are up to 73% and 100%, respectively.

Conclusions: Pancreas transplantation alone after TP in patients with pancreatitis or benign tumors improves the recipient's quality of life and reduces long-term mortality. Considering the amount of available organs and potential candidates, PTA can be a treatment option for patients after TP with chronic pancreatitis or benign tumors.
