Total pancreatectomy and islet autotransplantation (TPIAT) for refractory chronic pancreatitis has been performed at our center from 2006. We employed anti-inflammatory treatment using IL-1β and TNF-α blockers to improve graft outcomes. We present results on islet characteristics and glycemic control post-TPIAT from this large cohort of patients. Our database of 200 consecutive TPIAT procedures performed were retrospectively reviewed. We collected demographics, pancreas and islet characteristics. Patient follow-ups were performed at 3, 6, 12 m and then annually. Outcomes measures included glycemic control, pain relief and narcotic use. Baseline patient characteristics (age, sex, BMI, etiology, C-peptide and HbA1c, duration of symptoms) and isolation results were shown in Table 1A and post-TPIAT fasting glucose, HbA1c, C-peptide and daily insulin use in Table 1B. The insulin independence rate at 3, 6 and 12 months increased with time from 15%, 24 % and 27%, respectively). At 1 year, pain score was significantly improved (p<0.0001). Narcotic free rate also increased to 47% at 6 months and 56% at 1 year. Most post-TPIAT patients preserved hypoglycemic awareness and good pain relief. A cohort of patients remained normoglycemic without insulin and this group can be further studied to identify the factors that prevent the incidence of T3cDM after TPIAT.
