Abstract
BACKGROUND/OBJECTIVE This study is to assess immunological and graft survival outcomes after pancreas transplant at a single institute in Asia. METHODS Patients undergoing pancreas transplant with enteric drainage were included. Clinical data and outcomes were evaluated and compared between each subgroup. RESULTS There were 165 cases of pancreas transplant, including 38 (23 %) simultaneous pancreas-kidney transplant (SPK), 24 (15 %) pancreas after kidney transplant (PAK), 75 (46 %) pancreas transplant alone (PTA), and 28 (17 %) pancreas before kidney transplant (PBK). The overall surgical complication rate was 46.1 %, with highest (62.5 %) in PAK and lowest (32.0 %) in PTA, P = 0.008. The late complications included 32.7 % infection and 3.6 % malignancy. Overall rejection of pancreas graft was 24.8 % including 18.2 % acute and 9.7 % chronic rejection. Rejection was highest in PTA group (36.0 %) and lowest in PBK (3.6 %). There were 56 cases (33.9 %) with graft loss in total, with highest graft loss rate in PTA (38.7 %). The 1-year, 5-year and 10-year pancreas graft survivals for total patients were 98.0 %, 87.7 % and 70.9 % respectively. CONCLUSIONS Enteric drainage in pancreas transplant could be applied safely not only in SPK but also in other subgroups. Enteric drainage itself would not compromise the immunological and graft survival outcomes.

Abstract
OBJECTIVES Pancreatic transplantation is usually performed simultaneously with renal transplantation in the setting of end-stage nephropathy and type 1 diabetes. Surgical methods for dealing with exocrine secretions include bladder drainage, direct duodenojejunostomy and Roux-en-Y (ReY) enteric drainage. Roux-en-Y may confer an advantage over duodenojejunostomy because it distances enteric content from the transplant duodenal anastomosis. We examined the effect of enteric drainage method on transplant outcomes. METHODS Data were obtained from the UK transplant registry on 2172 consecutive pancreatic transplants. Early graft loss was the primary endpoint. Secondary endpoints included return to theater, length of inpatient stay, readmission with pancreatitis, graft survival, and patient survival. RESULTS There was no protective effect of ReY drainage (early graft loss, 4.6% vs 3.1%, P = 0.30; hazard ratio, 0.98; 95% confidence interval, 0.63-1.52; P = 0.91). There was a significant association between ReY and return to theater, reflecting either the technique or indication for ReY (multivariate odds ratio, 2.05; 95% confidence interval, 1.38-3.06; P < 0.01). The effect of transplant center on graft survival was assessed and adjusted for. CONCLUSIONS There was no evidence of a protective benefit of ReY drainage over duodenojejunostomy, but there was an increased risk of return to theater.

Abstract
PURPOSE OF REVIEW The surgical techniques of pancreas transplantation have been evolving and significantly improved over time. This article discusses different current techniques and their modifications. RECENT FINDING At this time, the most commonly used technique is systemic venous drainage (for venous outflow) and enteric drainage (for management of exocrine pancreatic secretions). However, new modifications of established techniques such as gastric or duodenal exocrine drainage and venous drainage to the inferior vena cava continue to be introduced. SUMMARY This article provides a state-of the-art review of the most prevalent up-to-date surgical techniques as well as a synopsis of their specific risks and benefits. The article also provides the most current registry data regarding utilization of different surgical techniques in the United State and worldwide.

Abstract
Outcomes of old-donor simultaneous pancreas-kidney transplantation (SPKT) have not been thoroughly studied. Scientific Registry of Transplant Recipients data reported for SPKT candidates receiving dialysis wait-listed between 1993 and 2008 (n = 7937) were analyzed for outcomes among those who remained listed (n = 3301) and of SPKT recipients (n = 4636) using multivariable time-dependent regression models. Recipients were stratified by donor/recipient age (cutoff 40 years) into: young-to-young (n = 2099), young-to-old (n = 1873), old-to-young (n = 293), and old-to-old (n = 371). The overall mortality was 12%, 14%, 20%, and 24%, respectively, for those transplanted, and 50% for those remaining on the waiting list. On multivariable analysis, old-donor SPKT was associated with significantly higher overall risks of patient death, death-censored pancreas, and kidney graft failure in both young (73%, 53%, and 63% increased risk, respectively) and old (91%, 124%, and 85% increased risk, respectively) recipients. The adjusted relative mortality risk was similar for recipients of old-donor SPKT compared with wait-listed patients including those who subsequently received young-donor transplants (aHR 0.95; 95% CI 0.78, 1.12) except for candidates in OPOs with waiting times ≥604 days (aHR 0.65, 95% CI 0.45-0.94). Old-donor SPKT results in significantly worse graft survival and patient mortality without any waiting-time benefit as compared to young-donor SPKT, except for candidates with expected long waiting times.

Abstract
Magnetic resonance imaging (MRI) plays an important role in the evaluation of pancreas transplantation. Standard MRI, magnetic resonance angiography, and MR cholangiopancreatography can demonstrate the changes of the anatomy after transplantation. Vascular complications are assessed by MR angiography. Magnetic resonance cholangiopancreatography reveals ductal changes resulting from acute and/or chronic rejection and determines leaks with the use of a secretin-stimulated MR cholangiopancreatography. Serial contrast-enhanced MRI may detect the diminished perfusion that is related to the graft rejection or vascular complications. In this paper, we reviewed types of pancreas transplantation procedures, complications that arise in a short and/or a long term after the transplantation, and their assessment by MRI.

Abstract
PURPOSE To evaluate the role of color Doppler ultrasonography in the postoperative surveillance of the vascular complications involving pancreas allografts. METHODS A retrospective analysis of a consecutive series of 223 pancreas transplantations was performed. All recipients received antithrombotic prophylaxis, which was tailored to the individual's estimated risk of thrombosis. All patients were monitored with daily color Doppler ultrasonography during the first post-transplant week and thereafter whenever clinically indicated. Vascular complications were defined as all thrombotic events requiring: increased anticoagulant therapy, angiography with fibrinolytic therapy, or repeat surgery. RESULTS The overall patient survival rates at one, three, and five years after transplantation were 94.7%, 93.3%, and 91%, respectively. The overall graft survival rates at the same time points were 87.4%, 79.6%, and 75.6%, respectively. In 28 of the 223 cases (12.5%) graft thromboses were diagnosed with Doppler ultrasound within the first 10 days after transplantation. In 3 cases, graft pancreatectomies were performed because of a complete loss of blood flow in the parenchyma. An attempt to rescue the graft was made in 18 patients. Fourteen of these grafts were saved and are still functioning (77.7%); and 4 rescue attempts failed and the grafts were subsequently explanted (32.3%). CONCLUSION Color Doppler ultrasound is a suitable tool for postoperative surveillance of pancreas transplant recipients. Its use can lead to early diagnosis and timely treatment of vascular complications.

Abstract
AIM: To establish the pig model of pancreatoduodenal transplantation with enteric drainage (ED) and portal venous drainage (PVD).
METHODS: Forty-six hybrid Landrace pigs were divided into two groups (donors and recipients) randomly, and pancreatoduodenal allotransplantation was performed. Donors were perfused via abdominal aorta without clamping the portal venous outflow with UW solution at 80100 cm H2O after heparinization. Whole pancreato-duodenal grafts were harvested with segments of abdominal aorta and portal vein, and shaped under 4 °C UW solution. Then, end-to-end anastomosis was performed with the donor iliac artery bifurcation Y graft to the recipient superior mesenteric artery and celiac artery. Furthermore, type I diabetes model was made by removal of the recipient pancreas. The venous anastomosis was reconstructed between the donor portal vein and the recipient superior mesentery vein. Meanwhile, end-to-side anastomosis was performed with the donor common iliac artery bifurcation Y graft to the recipient abdominal aorta, and side-to-side intestinal anastomosis was performed between the donor duodenum and the recipient jejunum. External jugular vein was intubated for transfusion. Levels of plasma glucose, insulin and glucagon were measured during the operation and on the 1st, 3rd, 5th, and 7th d after operation.
RESULTS: Pancreatoduodenal allotransplantation was performed on 23 pigs of which 1 died of complication of anesthesia. The success rate of operation was 95.6%. Complications of operation occurred in two cases in which one was phlebothrombosis with an incidence of 4.6%, and the other was duodenojejunal anastomotic leak with an incidence of 4.6%. The level of plasma glucose decreased within 30 min, after removal of pancreas and recovered on the 2nd d after operation. The level of plasma insulin and glucagon increased within 30 min after removal of pancreas and recovered on the 2nd d after operation. Rejection occurred on the 1st d and reached the worst level on the 7th d after transplantation, without change of plasma insulin and glucagon or clinical symptoms of rejection.
CONCLUSION: Pancreatoduodenal transplantation in pigs can treat type I diabetes. ED and PVD can keep the function of endocrine in normal. The technique of pancreatoduodenal transplantation with ED and PVD may pave the way for the further application of pancreas transplantation in clinic.

Abstract
Diabetes is one of the most common chronic diseases in our society. While insulin treatment for diabetes type I could delay and reduce the incidence of diabetic complications, it is associated with an increased risk of severe hypoglycemia. To restore physiologic insulin metabolism, transplantation of insulin producing cells (pancreatic Beta cells) represent the sole available therapy. It could be done either through pancreas or islet of Langerhans transplantation. In this paper, we review actual knowledge regarding these two types of transplantations.

Abstract
OBJECTIVE The purpose of our study was to focus on the early diagnosis and treatment of vascular complications after simultaneous pancreas-kidney (SPK) transplantation. Description of the technique for salvage of the graft after venous thrombosis (VT) is also provided. METHODS From July 1994 to December 2002, 14 patients of 206 SPK transplant recipients had partial VT. Partial splenic VT (PSVT) was documented in 10 patients (4.8%), two had complete thrombosis of the splenic vein, one partial superior mesenteric thrombosis, and one developed partial thrombosis of the splenic and superior mesenteric vein. Four patients developed complete VT of the pancreas allograft and one superior mesenteric artery thrombosis. Our experience with four arteriovenous fistulae is also reported. The immunosuppression included tacrolimus, steroids, and monoclonal antibody to the IL-2 receptor. Thymoglobulin was introduced in June 2000 in our protocol combined with rapamycin or mycophenolate mofetil. These cases were identified following the intravenous (iv) use of tacrolimus with or without anti-IL-2R therapy. One case of complete VT is also reported one month following transplantation in a recipient with high rapamycin levels. Diagnosis was established during routine color Doppler ultrasonography. RESULTS Partial VT was effectively treated with anticoagulation. Complete VT required surgical thrombectomy. In our series, the pancreas was salvaged successfully in all patients with the technique described here. CONCLUSION Early diagnosis of vascular complications after pancreas transplantation is of paramount importance for the appropriate treatment with organ salvage. Based on our experience, we suggest that VT can be effectively treated with anticoagulation. Aspirin is sufficient for PSVT.

Abstract
The incidence, timing and site of infections among the different categories of pancreas transplant recipients were investigated. Patients were divided into three groups: pancreas transplant alone (PTA), pancreas after kidney transplant (PAK), or simultaneous pancreas and kidney (SPK) transplants. Length of follow-up, time to death, pancreas graft survival, incidence, timing and site of bacterial infections were noted. Our study showed that at least 75% of pancreas transplant recipients experienced at least one infection (range from 77.8% in the PTA group to 86.7% in the PAK group). The SPK group presented the highest rate of infections with 35.1 infections per 1000/patient-days. Symptomatic urinary tract infections were the most common cause of infection in all patients. The incidence of infections was higher during the first month after transplantation, except for the SPK transplant group, where infections occurred over a longer time period.

Abstract
Despite recent advancements in surgical technique and immunosuppressive therapy, postoperative complications of pancreatic transplantation are still common. A complex spectrum of such adverse events includes graft rejection, peripancreatic fluid collections, pancreatitis, exocrine leaks, vascular thrombosis, and hemorrhage. Sonography plays a key role in the initial evaluation of the transplanted pancreas. Gray-scale sonography, duplex Doppler imaging, and sonographic guidance for percutaneous biopsy all contribute to posttransplantation evaluation and detection of sequelae. Color and power Doppler imaging offer valuable information regarding the regional vasculature and potential vascular complications. Because gray-scale sonographic findings alone are often nonspecific, several clinical criteria, including those from biochemical analysis of the urine and serum, must be reviewed with the sonographic findings to provide a thorough evaluation of the transplanted pancreas. When used in conjunction with serologic and urinary markers, the findings from sonography can help direct management options or suggest the need for further examination. Therefore, an understanding of the spectrum of complications combined with knowledge concerning the limitations of this imaging modality are essential for proper diagnosis and effective treatment.

Abstract
Simultaneous pancreas-kidney transplant (SPK) is now a common treatment for insulin-dependent diabetic patients with end-stage renal disease. Renal graft survival rates after SPK have been less well studied. This study compared the kidney survival results for 3642 SPK and 2374 cadaveric renal transplants (CRT) in type I diabetic patients at 112 US transplant centers reported to UNOS during 1994 through 1997. The analysis included follow-up information through September 2000. The kidney graft survival rates were significantly lower among recipients of CRT compared with SPK recipients (P < 0.001). Patients who received SPK were younger, less often sensitized, transplanted after shorter periods on dialysis, and less often black. The donors of SPK organs were younger, more often died from head trauma, were less often female, and more often black. SPK renal grafts were transplanted with a shorter cold ischemia time to more poorly HLA-matched recipients. After adjustment of these and other factors, whether a patient was recipient of CRT or SPK was not associated with increased risk of kidney graft failure or patient death. SPK recipients experienced half the rate of delayed kidney function (11% versus 23%) but nearly double the rate of rejections during the initial hospitalization (15% versus 9%) compared with CRT recipients. SPK was associated with better renal allograft survival compared with CRT, despite a higher rate of renal allograft rejection. This observation was explained by favorable donor and recipient factors in the SPK group. After controlling for these factors, SPK provided no protective or detrimental effect on short-term renal allograft or patient survival.

Abstract
OBJECTIVE To ascertain whether simple indexes of insulin sensitivity based on a fasting blood sample may be reliable measures of insulin sensitivity in combined kidney-pancreas- transplanted patients. RESEARCH DESIGN AND METHODS Estimates of insulin sensitivity based on fasting plasma glucose, insulin (homeostasis model assessment of insulin sensitivity [HOMA-IS], Quantitative Insulin Sensitivity Check Index [QUICKI]), and free fatty acid (revised QUICKI) concentrations were compared with insulin sensitivity as assessed with the gold standard technique (euglycemic-hyperinsulinemic clamp) in 22 patients who had undergone kidney-pancreas transplantation (KP-Tx) and 18 matched healthy subjects (NOR). RESULTS In KP-Tx patients, indexes based on the glucose-insulin product, HOMA-IS (r = 0.47, P = 0.03) and QUICKI (r = 0.47, P = 0.03), were shown to be reliable measures of insulin sensitivity. The introduction of fasting plasma free fatty acid concentration in the revised QUICKI (r = 0.76, P < 0.0001) considerably improved the power of prediction of the clamp-based measure of insulin sensitivity as observed in the healthy control subjects (r = 0.83, P < 0.0001). CONCLUSIONS This study shows that in KP-Tx patients, HOMA-IS and QUICKI are reliable measures of insulin sensitivity; the additional incorporation of fasting plasma free fatty acid concentration into the glucose-insulin product (revised QUICKI) resulted in a considerably more powerful index.

Abstract
Islet allotransplantation can provide prolonged insulin independence in selected individuals with type 1 diabetes. Whether islet transplantation also restores hypoglycemic counterregulation is unclear. To determine if hypoglycemic counterregulation is restored by islet transplantation, we studied hormone responses and hypoglycemic symptom recognition in seven insulin-independent islet transplant recipients using a 3-h stepped hypoglycemic clamp, and compared their responses to those of nontransplanted type 1 diabetic subjects and nondiabetic control subjects. Glucagon responses of islet transplant recipients to hypoglycemia were significantly less than that observed in control subjects (incremental glucagon [mean +/- SE]: -12 +/- 12 vs. 64 +/- 22 pg/ml, respectively; P < 0.05), and not significantly different from that of nontransplanted type 1 diabetic subjects (-17 +/- 10 pg/ml). Epinephrine responses and symptom recognition were also not restored by islet transplantation (incremental epinephrine [mean +/- SE]: 195 +/- 128 [islet transplant recipients] vs. 238 +/- 73 [type 1 diabetic subjects] vs. 633 +/- 139 pg/ml [nondiabetic control subjects], P < 0.05 vs. control; peak symptom scores: 3.3 +/- 0.9 [islet transplant recipients] vs. 3.1 +/- 1.1 [type 1 diabetic subjects] vs. 6.7 +/- 0.8 [nondiabetic control subjects]). Thus the results indicate that despite providing prolonged insulin independence and near-normal glycemic control in these patients with long-standing type 1 diabetes, hypoglycemic hormonal counterregulation and symptom recognition were not restored by intrahepatic islet transplantation.

Abstract
Recent success using a steroid-free immunosuppressive regimen has renewed enthusiasm for the use of islet transplantation to treat diabetes. Toxicities associated with the continued use of a calcineurin inhibitor may limit the wide-spread application of this therapy. Biological agents that block key T-cell costimulatory signals, in particular the CD28 pathway, have demonstrated extraordinary promise in animal models. LEA29Y (BMS-224818), a mutant CTLA4-Ig molecule with increased binding activity, was evaluated for its potential to replace tacrolimus and protect allogeneic islets in a preclinical primate model. Animals received either the base immunosuppression regimen (rapamycin and anti-IL-2R monoclonal antibody [mAb]) or the base immunosuppression and LEA29Y. Animals receiving the LEA29Y/rapamycin/anti-IL-2R regimen (n = 5) had significantly prolonged islet allograft survival (204, 190, 216, 56, and >220 days). In contrast, those animals receiving the base regimen alone (n = 2) quickly rejected the transplanted islets at 1 week (both at 7 days). The LEA29Y-based regimen prevented the priming of anti-donor T- and B-cell responses, as detected by interferon-gamma enzyme-linked immunospot and allo-antibody production, respectively. The results of this study suggest that LEA29Y is a potent immunosuppressant that can effectively prevent rejection in a steroid-free immunosuppressive protocol and produce marked prolongation of islet allograft survival in a preclinical model.
