Does Timepoint of Surgical Procedure Affect the Outcome in Simultaneous Pancreas-Kidney Transplantation? A Retrospective Single-Center Analysis over 20 Years. J Clin Med 2024; 13:3688. [PMID: 38999254 PMCID: PMC11242423 DOI: 10.3390/jcm13133688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 06/13/2024] [Accepted: 06/20/2024] [Indexed: 07/14/2024] Open
Abstract
Background: Sleep deprivation and disturbances in circadian rhythms may hinder surgical performance and decision-making capabilities. Solid organ transplantations, which are technically demanding and often begin at uncertain times, frequently during nighttime hours, are particularly susceptible to these effects. This study aimed to assess how transplant operations conducted during daytime versus nighttime influence both patient and graft outcomes and function. Methods: simultaneous pancreas-kidney transplants (SPKTs) conducted at the University Hospital of Leipzig from 1998 to 2018 were reviewed retrospectively. The transplants were categorized based on whether they began during daytime hours (8 a.m. to 6 p.m.) or nighttime hours (6 p.m. to 8 a.m.). We analyzed the demographics of both donors and recipients, as well as primary outcomes, which included surgical complications, patient survival, and graft longevity. Results: In this research involving 105 patients, 43 SPKTs, accounting for 41%, took place in the daytime, while 62 transplants (59%) occurred at night. The characteristics of both donors and recipients were similar across the two groups. Further, the rate of (surgical) pancreas graft-related complications and reoperations (daytime 39.5% versus nighttime 33.9%; p = 0.552) were also not statistically significant between both groups. In this study, the five-year survival rate for patients was comparable for both daytime and nighttime surgeries, with 85.2% for daytime and 86% for nighttime procedures (p = 0.816). Similarly, the survival rates for pancreas grafts were 75% for daytime and 77% for nighttime operations (p = 0.912), and for kidney grafts, 76% during the day compared to 80% at night (p = 0.740), indicating no significant statistical difference between the two time periods. In a multivariable model, recipient BMI > 30 kg/m2, donor age, donor BMI, and cold ischemia time > 15 h were independent predictors for increased risk of (surgical) pancreas graft-related complications, whereas the timepoint of SPKT (daytime versus nighttime) did not have an impact. Conclusions: The findings from our retrospective analysis at a big single German transplant center indicate that SPKT is a reliable procedure, regardless of the start time. Additionally, our data revealed that patients undergoing nighttime transplants have no greater risk of surgical complications or inferior results concerning long-term survival of the patient and graft. However, due to the small number of cases evaluated, further studies are required to confirm these results.

Mizerska A, Durlik M, Kędzierska-Kapuza K. Nutritional Risk of Candidates for Simultaneous Pancreatic-Kidney Transplantation-A Narrative Review. Nutrients 2023; 15:4179. [PMID: 37836461 PMCID: PMC10574362 DOI: 10.3390/nu15194179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 09/14/2023] [Accepted: 09/21/2023] [Indexed: 10/15/2023] Open
Abstract
INTRODUCTION Not much is known about the significance of nutritional status and support in transplant surgery, least of all in simultaneous pancreatic and kidney transplantation. Malnutrition in the context of simultaneous pancreatic-kidney transplantation seems to be complex and a still poorly investigated problem. Since SPKTX is highly qualified and also has a small volume procedure, it is difficult to obtain data from large cohorts of patients. The aim of this article is to gather existing evidence and information about the subject, as well as to elicit some questions and goals for the future. METHODS We searched through the Pub-Med database using the keywords "pancreas and kidney transplantation" combined with "nutritional risk", "nutritional status", "malnutrition", "nutritional intervention", and "frailty", finding a total of 4103 matching results. We then narrowed it down to articles written in English with the full text available. We also researched through the references of articles most accurately matching our researched terms. RESULTS There are numerous tools that have been investigated for the screening of malnutrition, such as the NRI index, PNI index, NLR, SGA scale, and NRS-2002 scale, each of which proved to be of some use in predicting patient outcomes in different surgical settings. Since all of them differed in components and assessed parameters and, in the absence of more sensitive or infallible indicators, the most reasonable approach seems to evaluate them jointly. CONCLUSION It is important to underline the necessity of nutritional screening and the subsequent introduction of adequate therapy while awaiting transplantation in an attempt to improve results. Considering the complexity of surgical procedures and the severity of underlying diseases with their intense metabolic components, the patient's nutritional status seems to significantly influence results. Consequently, nutritional risk assessments should be a part of the routine care of patients qualified for transplantation.

Abstract
INTRODUCTION The influence of sex on outcomes following simultaneous pancreas-kidney transplantation (SPKT) in the modern era is uncertain. METHODS We retrospectively studied 255 patients undergoing SPKT from 11/2001 to 8/2020. Cases were stratified according to donor (D) sex, recipient (R) sex, 4 D/R sex categories, and D/R sex-matched versus mismatched. RESULTS D-male was associated with slightly higher patient (p = .08) and kidney (p = .002) but not pancreas (p = .23) graft survival rates (GSR) compared to D-female. There were no differences in recipient outcomes other than slightly higher pancreas thrombosis (8% R-female vs. 4.2% R-male, p = .28) and early relaparotomy rates in female recipients (38% R-female vs. 29% R-male, p = .14). When analyzing the 4 D/R sex categories, the two D-male groups had higher kidney GSRs compared to the two D-female groups (p = .01) whereas early relaparotomy and pancreas thrombosis rates were numerically higher in the D-female/R-female group compared to the other three groups. Finally, there were no significant differences in outcomes between sex-matched and sex-mismatched groups although overall survival outcomes were lower with female donors irrespective of recipient sex. CONCLUSIONS The influence of D/R sex following SPKT is subject to multiple confounding issues but survival rates appear to be higher in D-male/R-male and lower in D-female/R-male categories.

Abstract
The First World Consensus Conference on Pancreas Transplantation provided 49 jury deliberations regarding the impact of pancreas transplantation on the treatment of diabetic patients, and 110 experts' recommendations for the practice of pancreas transplantation. The main message from this consensus conference is that both simultaneous pancreas-kidney transplantation (SPK) and pancreas transplantation alone can improve long-term patient survival, and all types of pancreas transplantation dramatically improve the quality of life of recipients. Pancreas transplantation may also improve the course of chronic complications of diabetes, depending on their severity. Therefore, the advantages of pancreas transplantation appear to clearly surpass potential disadvantages. Pancreas after kidney transplantation increases the risk of mortality only in the early period after transplantation, but is associated with improved life expectancy thereafter. Additionally, preemptive SPK, when compared to SPK performed in patients undergoing dialysis, appears to be associated with improved outcomes. Time on dialysis has negative prognostic implications in SPK recipients. Increased long-term survival, improvement in the course of diabetic complications, and amelioration of quality of life justify preferential allocation of kidney grafts to SPK recipients.

Abstract
Background Current solid organ pancreas transplantation protocols have differing donor criteria for donor pancreas acceptance and recipient eligibility criteria for transplant workup. We quantified this variation and compared current Australia and New Zealand (ANZ) solid pancreas transplant eligibility criteria with current international practice. Material/Methods A survey of donor and recipient eligibility criteria for solid pancreas transplantation was disseminated to 85 transplant units in 23 countries. Responses were grouped by regions (ANZ, North America, Eurotransplant, Europe, United Kingdom) and analyzed for significant differences between regions and for ANZ compared to all other regions. Results Responding UK pancreas transplant units reported the highest mean donor upper age limit (61 years old) and the highest mean donation after cardiac death donor (DCD) age limit (55 years old). All responding UK and USA units utilized DCD pancreas donors and accepted suitable type 2 diabetes (T2DM) recipients for pancreas transplantation; however, this was less common among responding European or Eurotransplant units. ANZ mean standard and DCD pancreas donor upper age limits (47 and 35 years old, respectively) were lower compared to all other regions (54 years old and 48 years old, respectively). Conclusions Pancreas donor age limits, DCD pancreas donor utilization, and transplanting T2DM recipients differ between responding pancreas transplant units. ANZ units have more conservative donor upper age limits compared to other responding units. Increased utilization of DCD pancreas donors and T2DM recipients while standardizing pancreas donor age limits might increase donor numbers and improve access to solid pancreas transplantation both locally and abroad.

Abstract
Donor cardiac arrest and cardiopulmonary resuscitation (CACPR) has been considered critically because of concerns over hypoperfusion and mechanical trauma to the donor organs. We retrospectively analyzed 371 first simultaneous pancreas–kidney transplants performed at the Medical University of Innsbruck between 1997 and 2017. We evaluated short‐ and long‐term outcomes from recipients of organs from donors with and without a history of CACPR. A total of 63 recipients received a pancreas and kidney graft from a CACPR donor. At 1, and 5‐years, patient survival was similar with 98.3%, and 96.5% in the CACPR and 97.0%, and 90.2% in the non‐CACPR group (log rank P = 0.652). Death‐censored pancreas graft survival was superior in the CACPR group with 98.3%, and 91.4% compared to 86.3%, and 77.4% (log rank P = 0.028) in the non‐CACPR group, which remained statistically significant even after adjustment [aHR 0.49 (95% CI 0.24–0.98), P = 0.044]. Similar relative risks for postoperative complications Clavien Dindo > 3a, pancreatitis, abscess, immunologic complications, delayed pancreas graft function, and relative length of stay were observed for both groups. Donors with a history of CACPR are, in the current practice, safe for transplantation. Stringent donor selection and short CPR durations may allow for outcomes surpassing those of donors without CACPR.

Abstract
INTRODUCTION Some factors affect the pancreas of a marginal donor, and although their influence on graft survival has been determined, there is an increasing consensus to accept marginal organs in a controlled manner to increase the pool of organs. Certain factors related to the recipient have also been proposed as having negative influence on graft prognosis. The objective of this study was to analyze the influence of these factors on the results of our simultaneous pancreas-kidney (SPK) transplantation series. MATERIALS AND METHODS Retrospective analysis of 126 SPK transplants. Donors and recipients were stratified in an optimal group (<2 expanded donor criteria) and a risk group (≥2 criteria). A pancreatic graft survival analysis was performed using a Kaplan-Meier test and log-rank test. Prognostic variables on graft survival were studied by Cox regression. Postoperative complications (graded by Clavien classification) were compared by χ2 test or Fisher test. RESULTS Median survival of pancreas was 66 months, with no significant difference between groups (P > .05). Multivariate analysis showed risk factors to be donor age, cold ischemia time, donor body mass index, receipt body mass index, and receipt panel-reactive antibody. CONCLUSIONS In our series, the use of pancreatic grafts from donors with expanded criteria is safe and has increased the pool of grafts. Different variables, both donor and recipient, influence the survival of the pancreatic graft and should be taken into account in organ distribution systems.

Abstract
Recent changes to pancreas graft allocation policy have increased the number of organs available for regional and distant sharing, which results in a corresponding increase in preservation time. We sought to systematically assess the impact of cold ischemia time (CIT) on outcomes post-transplant. A retrospective review of 1253 pancreas transplants performed at a single transplant center was performed to correlate CIT to transplant outcomes. The rate of technical failure (TF) increased with 20+ hours of CIT, with a 2.7-fold to 6.2-fold increased rate of TF for pancreas after kidney (PAK), simultaneous pancreas and kidney (SPK), and pancreas transplants overall. Long-term graft survival was best with <12 hours of CIT; graft failure increased 1.2-fold to 1.4-fold with 12-24 hours of CIT and 2.2-fold with 24+ hours. CIT had less influence on the pancreas transplant alone category than either SPK or PAK and had markedly more influence on grafts from older (age >25 years) and overweight (body mass index >25) donors. In the final analysis, grafts with <12 hours of CIT performed the best overall, and strategies that reduce CIT (such as early allocation, pre-recovery cross-matching, and chartered flights for organs) should be considered whenever possible.

Abstract
BACKGROUND Simultaneous pancreas and kidney transplantation (SPKTx) is the most commonly performed multiorgan transplantation procedure worldwide. Transplanted organs are the main source of complication; however, some postoperative complications are not directly related to the pancreatic or renal grafts. The goal of this study was to evaluate the prevalence, type, and severity of postoperative complications not related to transplanted kidney or pancreas among SPKTx recipients. METHODS Complications unrelated to transplanted pancreas and kidneys among 112 SPKTx recipients were analyzed. The cumulative freedom from general surgical complications was assessed, and it was compared with cumulative freedom from complications related to kidney and pancreatic grafts. Severity of complications was classified according to a modified Clavien-Dindo scale. RESULTS The general surgery complication rate was 22.2%. Cumulative freedom from general surgical complications at days 60 and 90 after transplantation was 0.89 and 0.87, respectively. Cumulative freedom from general surgical complications was comparable with cumulative freedom from complications related to kidney grafts but significantly higher than cumulative freedom from complications related to pancreatic grafts (log-rank test, P < .001). The rates for grades of severity II, IIIa, IIIb, and IVb were 19.4%, 9.7%, 64.5%, and 6.4%, respectively. The most frequent cause of complications was intra-abdominal hematoma or abscess (25.8%). CONCLUSIONS The general surgical complication rate was comparable to the rate of complications originating from the renal grafts but significantly lower than the complication rate related to the transplanted pancreas. The incidence of general surgical complications could be defined as moderate, and the severity of this type of complication was low.

Abstract
OBJECTIVE Simultaneous pancreas and kidney transplantation (spktx) is the multiorgan transplantation. Thus various complications originated from transplanted organs and the complications that are not directly related to pancreatic or renal grafts could be developed at the same recipient. AIM The aim of this study is to explore whether there is a correlation between the severity of complications originated from transplanted pancreas, transplanted kidney and general surgical complication developed at the same spktx recipient. METHODS Complications which developed among 112 spktx recipients were divided into three groups: related to the pancreatic graft (PTXc), to the renal graft (KTXc) and the general surgical complication (GNc). Severity of postoperative complications using modified Dindo-Clavien scale recipients was evaluated for each group. The correlation of severity of coexisting complications from different complication groups was analyzed. RESULTS There were 22 recipients who developed the coexistence of complication between different complication groups. Complication originated from two and three complication groups developed 15 (68.2%) and 7 (31.8%) patients, respectively. There was not found correlation of the complication severity between: KTXc and GNc group, GNc and PTXc group, KTXc and PTXc group. The correlation (r = 0.84) of complication severity in recipients who developed concurrently complication from transplanted kidney, transplanted pancreas and general surgery complication was found. CONCLUSION The modified Dindo-Clavien scale is an useful methodology for the correlation description of complication severity in complex multiorgan transplantation such is spktx, especially when the complications originated from different, potentially independent from the pathophysiological point of view, sources.

Abstract
OBJECTIVE Identification of factors that have an impact on postoperative complications after simultaneous pancreas and kidney transplantation (SPKTx) could help overcome limitations of this kind of treatment. METHODS Postoperative complications among 112 SPKTx recipients were divided into 3 groups: related to transplanted pancreas (n = 66), related to transplanted kidney (n = 23) and general surgical complications (n = 31) 120 refers to complications among 112 recipients. According to the modified Clavien-Dindo scale, complications were classified according to their severity for each group. Risk factors for complication development related to donor, recipient, surgical technique, and immunosuppression were included to establish the multivariable model using logistic regression. RESULTS Multiple regression analysis showed the following independent factors influenced mortal complications due to transplanted pancreas: age of donor (OR, 1.07; P < .04), duration of vascular pancreas anastomosis above 35 minutes (OR, 3.94; P < .04) and duration of recipient dialysis above 24 months before transplantation (OR, 0.14; P < .01). Area under receiver operating characteristic curve for this model was 0.8. CONCLUSION To improve results, the following modification of identified risk factors should be assumed: selection of donor in term of age, shortening of the second warm ischemia time, and adjustment of the waiting list to avoid prolongation of recipient dialysis before SPKTx.

Abstract
A significant number of pancreases procured for transplantation are deemed unsuitable due to concerns about graft quality and the associated risk of complications. However, this decision is subjective and some declined grafts may be suitable for transplantation. Ex vivo normothermic perfusion (EVNP) prior to transplantation may allow a more objective assessment of graft quality and reduce discard rates. We report ex vivo normothermic perfusion of human pancreases procured but declined for transplantation, with ABO-compatible warm oxygenated packed red blood cells for 1-2 h. Five declined human pancreases were assessed using this technique after a median cold ischemia time of 13 h 19 min. One pancreas, with cold ischemia over 30 h, did not appear viable and was excluded. In the remaining pancreases, blood flow and pH were maintained throughout perfusion. Insulin secretion was observed in all four pancreases, but was lowest in an older donation after cardiac death pancreas. Amylase levels were highest in a gland with significant fat infiltration. This is the first study to assess the perfusion, injury, as measured by amylase, and exocrine function of human pancreases using EVNP and demonstrates the feasibility of the approach, although further refinements are required.

Abstract
BACKGROUND The high rate of complication after pancreas transplantation not only had an impact on recipient quality of life and survival but also had significant financial implications. Thus, monitoring transplant center performance was crucial to indentifying changes in clinical practice that result in quality deterioration. OBJECTIVE To evaluate retrospectively the quality of the single, small pancreatic transplant program and to establish prospective monitoring of the center using risk-adjusted cumulative sum (CUSUM). METHODOLOGY From 1988 to 2014, 119 simultaneous pancreas and the kidney transplantations (SPKTx) were performed. The program was divided into 3 eras, based on surgical technique and immunosuppression. Analyses of the 15 fatal outcomes due to complication from pancreatic graft were performed. The risk model was developed using multivariable logistic regression analysis based on retrospective data of 112 SPKTx recipients. The risk-adjusted 1-sided CUSUM chart was plotted for retrospective and prospective events. The upper control limit was set to 2. RESULTS There were 2 main causes of death: multiorgan failure (73.3%; 11/15) and septic hemorrhage (26.7%; 4/15). Quality analysis using the CUSUM chart revealed that the process was not homogeneous; however, no significant signal of program deterioration was obtained and the performance of the whole program was within the settled control limit. CONCLUSION For a single pancreatic transplant center. The risk-adjusted CUSUM chart was a useful tool for quality program assessment. It could support decision making during traditional surgical morbidity and mortality conferences. For small transplant centers, increasing the sensitivity of the CUSUM method by lowering the upper control limit should be considered. However, an individual assessment approach of the for particular centers is recommended.

Abstract
OBJECTIVES Because of the shortage of available organs for transplants, graft allocation polices have been modified recently. This report deals with the effect of using organs after rescue allocation for pancreas transplant in a single center in the Eurotransplant Region to possibly expand the donor pool. MATERIALS AND METHODS A retrospective analysis was performed. Between 2007 and 2010, thirty-one pancreas transplants were performed at the University Hospital of Leipzig, in Leipzig, Germany. Among these, 7 cases used rescue organs. These organs had been officially offered to, but rejected by, at least 3 consecutive transplant centers. Donor/recipient and clinical/laboratory transplant/posttransplant outcomes from patients receiving rescue organs were collected and were compared with organs from conventional donors. RESULTS Mean donor age was greater in the rescue organ group than in the conventional donor group (28.3 ± 10.7 y vs 23.0 ± 12.5 y). During follow-up (2.3 ± 0.6 y rescue organ group vs 3.9 ± 1.2 y conventional donor group), patient, kidney, and pancreas graft survival rates were 85% in all 3 categories in the rescue organ group, whereas outcomes for conventional donors were 88%, 85%, and 83%. Incidences of pancreatic graft thrombosis, delayed graft function, acute and late rejection episodes (eg, perioperative complications) were comparable between groups. No differences existed between mean serum urea levels and mean HbA1c levels between groups 2 years after transplant. Whereas 2 years after surgery, mean serum creatinine levels (rescue organ group, 78.8 ± 21.0 μmol/L vs 114.3 ± 28.4 μmol/L in the conventional donor group) showed significant differences between groups. CONCLUSIONS Results are promising. Further pro-spective studies are warranted to evaluate routine transplant of organs after rescue allocation.

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
Technical failure (TF) continues to have a significant impact on the success of pancreas transplantation. We assessed risk factors for TF in 1115 pancreas transplants performed at a single center between 1998 and 2011. The overall TF rate was 10.2%. In a multivariable model, donor BMI ≥ 30 (HR 1.87, p = 0.005), donor Cr ≥ 2.5 (HR 3.16, p = 0.007), donor age >50 (HR 1.73, p = 0.082) and preservation time >20 h (HR 2.17, p < 0.001) were associated with TF. Bladder drainage of exocrine secretions was protective (HR 0.54, p = 0.002). We incorporated these factors in a Composite Risk Model. In this model the presence of one risk factor did not significantly increase risk of TF (HR 1.35, p = 0.346). Two risk factors in combination increased risk greater than threefold (HR 3.65, p < 0.001) and three risk factors increased risk greater than sevenfold (HR 7.66, p = <0.001). The analysis also identified many factors that were not predictive of TF, including previous transplants, immunosuppressive agent selection, and almost all recipient demographic parameters. While the model suggests that two or more risk factors predict TF, strategies to reduce preservation time may mitigate some of this risk.

Abstract
INTRODUCTION Simultaneous pancreas-kidney transplantation (SPK) is an alternative to kidney transplantation (KTx) for type 1 diabetic patients with end-stage kidney disease. However, a fair comparison of SPK and KTx is difficult because of significant differences in donor, recipient, and transplantation procedure parameters. The aim of this study was to compare the early and long-term outcomes of SPK versus KTx in southwest Poland. MATERIAL AND METHODS Thirty-five diabetic dialysis patients who had SPK and 64 patients who had KTx were included in the analysis. RESULTS SPK recipients were younger (38±6 years versus 42±9 years) and received organs from younger donors (25±7 versus 43±12 years) compared to the KTx group. They had shorter kidney cold ischemia time (9±2 hours versus 22±7 hours) but worse HLA class II mismatches (1.4±0.6 versus 1.0±0.5). In the early postoperative period, three patients died from the SPK group and one patient died from the KTx group. Additionally, two SPK patients lost their pancreatic grafts, and five KTx patients lost their kidney grafts. One-year patient survival rates for the SPK and KTx groups were 88% and 98%, respectively, and 5-year, 81% and 93%, respectively. One-year kidney graft survivals rates for the SPK and KTx groups were 100% and 89%, respectively, and 5-years, 89% and 81%, respectively. One-year insulin-free survival among SPK patients was 90% and the 5-year survival rate was 76%. Excretory function of the transplanted kidneys was better among SPK group; however, the difference reached statistical significance only in posttransplant years 2 and 3: 63.5±20.1 versus 50.3±19.7 and 64.9±12.9 versus 51.6±21.8 mL/min/1.73 m2 for SPK and KTx, respectively. CONCLUSIONS Normoglycemia in SPK recipients did not improve patient survival at 5 years. The worse HLA compatibility in the SPK group did not lead to impaired kidney graft survival compared to KTx. Better kidney graft function among SPK recipients probably resulted from a more restrictive donor selection.

Abstract
INTRODUCTION The success of simultaneous pancreas-kidney transplantation (SPK) depends in a large degree on avoidance of surgical complications in the early postoperative period. The aim of the study was to analyze the Pre-procurement Pancreas Allocation Suitability Score (P-PASS) and the deceased donor parameters included within it as risk factors for early surgical complications after SPK. MATERIAL AND METHODS Forty-six consecutive donors whose kidney and pancreas were simultaneously transplanted were included in the study. RESULTS Donor age was older among recipients who lost their pancreatic grafts: 30.4±6.9 versus 24.1±6.9 years. Donor age was also older among recipients who lost their pancreatic grafts or died compared with those discharged with a functioning graft: 29.3±5.7 versus 24.0±6.9 years. Donor body mass index (BMI) was higher among patients who died compared with those who were discharged: 25.3±1.1 versus 23.2±2.5 kg/m2. P-PASS was higher in patients who lost their pancreatic grafts (17.6±2.1 vs 15.2±1.8) or died (15.3±1.9 vs 17.2±1.9), or lost pancreatic graft or died (15.2±1.8 vs 17.0±2.2) or with intra-abdominal infections (IAI; 17.1±1.7 vs 15.0±1.8). The incidence of donors≥30 years old was higher among recipients with IAI (45.4% vs 14.3%; P=.04). An higher rate of donors with P-PASS>16 was revealed among patients who lost their pancreatic grafts (26.7% vs 3.2%), died (26.7% vs 3.2%), lost the pancreatic graft or died (33.3% vs 6.4%), or experienced IAI (46.7% vs 9.7%). Multivariate logistic regression analysis revealed P-PASS (odds ratio 2.57; P=.014) and serum sodium (odds ration, 0.91; P=.048) to be important predictors of IAI development. CONCLUSION Older age and higher BMI among deceased donors increased the risk of IAI, pancreatic graft loss, or recipient death after SPK. Transplantation of a pancreas from a donor with a low P-PASS score was associated with a lower risk of surgical complications after SPK.

Abstract
PURPOSE Bladder drainage (BD) of pancreatic transplants is associated with a unique set of complications. We intended to analyze the incidence, indications, complications and long-term results of enteric conversion procedures (EC). METHODS Using a prospective database, 32 EC patients out of 433 simultaneous pancreas-kidney-transplant (SPK) recipients were identified. Graft and patient survival rates were compared with those after primary enteric drainage (ED). RESULTS The mean SPK-EC interval was 5.0 yr, and the mean patient follow-up was 13.8 yr. Indications for EC were genitourinary symptoms (62.5%), duodenal complications (15.6%), graft pancreatitis (12.5%), pyelonephritis (6.3%), and metabolic acidosis (3.1%). All patients reported significant long-term resolution of symptoms. Surgical complications, reoperations, early graft loss, and 30-d mortality occurred in 31.3%, 25.0%, 6.3%, and 3.1% of cases, respectively. Pancreatic graft and patient survival rates at 1, 5, and 10 yr after SPK were comparable between EC patients and ED patients at the same institution. CONCLUSION For the treatment of symptoms associated with BD, EC results in excellent long-term graft function and significant resolution of symptoms even years after SPK. Postoperative morbidity after EC including early reoperation and graft loss, however, has to be considered.

Abstract
Quality of most procured pancreata is considered acceptable or good by surgeons, but remains difficult to ascertain. Little is known on how often pancreata are refused for transplantation during back-table inspection. Purpose of this study was to determine the frequency and type of problems responsible for refusal during back-table inspection and to identify possible risk factors. All 134 pancreata accepted and procured for whole-organ transplantation and transported to the Leiden University Medical Center in the period February 2002 until May 2008 were included. These were retrospectively analyzed on donor characteristics, procurement characteristics, and (non-)critical problems. A total of 111 (82.8%) pancreata were transplanted while 23 (17.2%) were refused for transplantation during back-table inspection, regardless of procurement region (χ(2) = 0.16 p = 0.93). Fourteen pancreata (13.4%) were refused solely because of surgical injuries. In refused pancreata, on average 2.7 critical problems per pancreas were found and 0.6 non-critical problems (vs. 0.3 in transplanted pancreata, t = 1.83 p = 0.08). Chances of refusal increased in pancreata from older donors (odds ratio 1.08 [1.02-1.14]) procured in centers not performing pancreas transplantations (odds ratio 7.95 [2.43-25.97]). We conclude that pancreatic allografts are frequently refused during back-table inspection, partly because of the surgical injuries suggesting that quality of procurement may be improved.
