ABSTRACT BACKGROUND: Peripancreatic fluid collections (PPFC) are a serious complication after simultaneous pancreas-kidney transplantation (SPKTx). METHODS: Retrospective study for all 223 SPKTx performed from December 8, 1996, to October 10, 2011, to evaluate the risk factors (RF) and impact of PPFCs on outcomes was conducted. RESULTS: Clinically significant PPFCs were seen in 36 (16%) cases, all within 3 months after transplantation. Radiologic drainage resolved 2 (6%) cases, and 34 required laparotomy (mean [SD], 4 [7]). Compared with the non-PPFC group (n=186), the PPFC group had similar patient and total kidney graft survivals but significantly lower total pancreas survival (68% vs. 85%) and greater incidence of infections (75% vs. 46%, all P<0.05) at 5 years. PPFCs were associated with early graft pancreatitis in 18 (50%), pancreatic fistula in 20 (56%, 9 with obvious duodenal stump leak) and infection in the collection in 20 (56%) cases. Comparison of PPFCs with pancreas graft loss to the PPFCs with surviving grafts showed that the incidence of pancreatic fistula was greater in the former (90% pancreas graft loss vs. 42% pancreas graft survival, P<0.01). Binary logistic regression analysis of RF for developing PPFC showed a donor age >30 years to be significant (P=0.03; odds ratio, 3.4; confidence interval, 1.1-10.5) and a trend of association with donor body mass index >30 and pancreas cold ischemia time greater than 12 hr. CONCLUSIONS: PPFCs are associated with significant reduction in pancreas allograft survival and impact resource use. Donor age >30 years is a significant RF for their development. PPFCs associated with pancreatic fistula carry a greater risk for pancreas graft loss.

    ABSTRACT: The purpose of this study is to report the results of simultaneous pancreas-kidney (SPK) transplantations and describe the lessons learned from the early experiences of a single center. Between January 2002 and June 2013, a total of 8 patients underwent SPK transplantation. Clinical and radiologic data were reviewed retrospectively. Seven patients were diagnosed with type I diabetes mellitus and one patient became insulin-dependent after undergoing a total pancreatectomy because of trauma. Pancreas exocrine drainage was performed by enteric drainage in 4 patients and bladder drainage in 4 patients. Three patients required conversion from initial bladder drainage to enteric drainage due to urinary symptoms and duodenal leakage. Four patients required a relaparotomy due to hemorrhage, ureteral stricture, duodenal leakage, and venous thrombosis. There was no kidney graft loss, and 2 patients had pancreas graft loss because of venous thrombosis and new onset of type II diabetes mellitus. With a median follow-up of 76 months (range, 2-147 months), the death-censored graft survival rates for the pancreas were 85.7% at 1, 3, and 5 years and 42.9% at 10 years. The patient survival rate was 87.5% at 1, 3, 5, and 10 years. The long-term grafts and patient survival in the current series are comparable to previous studies. A successful pancreas transplant program can be established in a single small-volume institute. A meticulous surgical technique and early anticoagulation therapy are required for further improvement in the outcomes.

    ABSTRACT: Solitary Pancreas (SPT) and simultaneous kidney-pancreas (SPKT) transplants carry a high risk of surgical complications that may lead to the loss of the pancreas graft and impact later kidney function. The purpose of this study was to investigate the role of MDCT in the diagnosis of early complications and its impact on kidney function.
