Simultaneous pancreas and kidney (SPK) retransplantation in prior SPK recipients.

ABSTRACT

INTRODUCTION: We have performed 113 renal and 28 isolated pancreas retransplants in our cohort of more than 1200 prior simultaneous pancreas and kidney (SPK) recipients. On the basis of these experiences, we began performing repeat SPK in prior SPK recipients (n = 9). METHODS: This retrospective review summarizes our experience with repeat SPK transplantation in prior SPK recipients. Mean age at retransplant was 39 yr; mean interval to retransplant was 7.8 yr. Thirty-three percent were pre-dialysis. Eighty-nine percent of patients underwent transplant nephrectomy (five during the repeat SPK and three prior to it), and 78% underwent transplant pancreatectomy (four during the repeat SPK and three prior to it). Enteric drainage was performed in all repeat SPKs. RESULTS: Median length of stay was 11 d. Perioperative complications included the following renal artery thrombosis (1), pancreatic portal venous thrombosis (1), enteric leak (1), and hematoma (2). Overall pancreatic allograft survival was 78% at one yr and 67% at two yr. Overall renal allograft survival was 89% at one yr and 78% at two yr. Patient survival at one and three yr was 100%. CONCLUSIONS: Survival of repeat SPK allografts is acceptable despite the increased technical and immunologic demands of retransplantation. Graftectomy prior to or at the time of retransplantation is often necessary.
