A Prospective Observational Study of TPIAT

Multi-center, prospective, observational cohort study of patients undergoing total pancreatectomy with islet autotransplantation (TPIAT)

Patients who are undergoing TPIAT at one of the participating center are invited to participate in this observational study, with 450 participants anticipated. The aims of the study are: Aim 1: To determine (1a) whether patient and disease characteristics are associated with favorable pain and health-related quality-of-life outcomes (HRQOL) after TPIAT; (1b) the optimal timing of the TPIAT intervention to resolve pain and improve HRQOL; and (1c) in a subset of patients, the impact of central sensitization on pain resolution. Aim 2: To determine (2a) whether patient and disease characteristics are associated with favorable glycemic outcomes from the IAT procedure; and (2b) the optimal timing of TPIAT to obtain post-surgical insulin independence. Aim 3: To determine the cost-effectiveness of TPIAT.
