Background: Pancreatoduodenectomy is still hampered by significant morbidity. So far, there is no universally accepted technique aimed at minimizing postoperative complications. Herein, we compare three different reconstruction techniques. Methods: This is a retrospective study of a prospectively maintained database including 283 patients operated between January 2010 and December 2020. Three reconstruction techniques were compared: (1) the Neuhaus-style telescope pancreatojejunostomy, (2) the pancreatogastrostomy, and (3) the modified Blumgart-style, duct-to-mucosa pancreatojejunostomy. The primary endpoint consisted in determining the rates of clinically relevant postoperative pancreatic fistulas (CR-POPF); the secondary endpoints included 90 days morbidity and mortality rates. A propensity score matching analysis was used. Results: Rates of CR-POPF did not differ significantly between the groups (Neuhaus-style pancreatojejunostomy 16%, pancreatogastrostomy 17%, modified Blumgart-style pancreatojejunostomy 15%), neither in the unmatched nor in the matched analysis (p = 0.993 and p = 0.901, respectively). Similarly, no significant differences could be observed with regard to major morbidity (unmatched p = 0.596, matched p = 0.188) and mortality rates (unmatched p = 0.371, matched p = 0.209) within the first 90 days following surgery. Propensity-score matching analyses revealed, however, a higher occurrence of post-pancreatectomy hemorrhage after pancreatogastrostomy (p = 0.015). Conclusion: Similar CR-POPF rates suggest no crucial role of the applied reconstruction technique. Increased incidence of intraluminal post-pancreatectomy hemorrhages following pancreatogastrostomy demands awareness for meticulous hemostasis.

A positive crossmatch (XM+) is considered a contraindication to solid abdominal organ transplantation except liver transplantation (LT). Conflicting reports exist regarding the effects of XM+ on post-transplant outcomes. The goal of this retrospective single-center analysis is to evaluate the influence of XM+ on relevant outcome parameters such as survival, graft rejection, biliary and arterial complications. Forty-nine adult patients undergoing LT with a XM+ between 2002 and 2017 were included. XM+ LT recipients were matched 1:2 with crossmatch negative (XM−) LT recipients based on the balance of risk (BAR) score. Patient and graft survival were compared using Kaplan-Meier survival analysis and the log-rank test. Comparative analysis of clinical outcomes in XM+ and XM− groups were conducted. Patient and graft survival were similar in XM+ and XM− patients. Rejection episodes did not differ either. Recipients with a strong XM+ were more likely to develop a PCR+ CMV infection. A XM+ was not associated with a higher incidence of biliary or arterial complications. Donor age, cold ischemia time, PCR+ CMV infection and a rejection episode were associated with the occurrence of ischemic type biliary lesions. A XM+ has no effects on patient and graft survival or other relevant outcome parameters following LT.

Ein arteriovenoser Shunt ist der „golden standard“ fur den Gefaszugang bei Patienten mit dialysepflichtiger Niereninsuffizienz. Nach einer erfolgreichen Nierentransplantation wird der Shunt jedoch nicht mehr benotigt. In diesem Artikel mochten wir die kardiovaskularen Vorteile und potenziellen Probleme einer routinemasigen Shuntligatur nach einer Nierentransplantation erortern. Es erfolgte eine narrative Literaturrecherche in der Literaturdatenbank von MEDLINE, PubMed und Cochrane Database of Systematic Reviews bis inklusive April 2021. Eine Shuntligatur bei stabilen Nierentransplantatempfangern senkt den pulmonal arteriellen Druck und reduziert das Risiko eines Rechtsherzversagens und bringt damit ein geringeres kardiales Risiko mit sich. Die Entscheidung dazu sollte jedoch vorsichtig und patientenbezogen getroffen werden.

BACKGROUND There has been, to our knowledge, no reports on LifeCycle Pharma tacrolimus (LCPT) taken during pregnancy after simultaneous pancreas-kidney transplantation (SPK). Here, we report a 25-year-old female SPK recipient who gave birth to a healthy infant in posttransplant month 32. We analyzed the long-term graft function, obstetric/neonatal course, LCPT dosage, tacrolimus (TAC) levels, concomitant medication, and complications. CASE REPORT Her medical history consisted of type 1 diabetes with chronic nephropathy, arterial hypertension, and atypical haemolytic uremic syndrome with critical deterioration of her general condition requiring clinically indicated early termination of her first pregnancy prior to SPK. SPK was performed according to surgical standards. The immunosuppressive prophylaxis consisted of thymoglobulin, mycophenolate mofetil, standard TAC formulation, and steroids. Due to rapid TAC metabolism, the patient was converted from a standard TAC formulation to LCPT in the first month posttransplant. Her long-term immunosuppression, including the obstetric and peripartal course, consisted of LCPT, prednisolone, and azathioprine. She was normotensive without antihypertensive medication and maintained excellent function of both grafts during the observation period of 48 months posttransplant. All (mostly infectious) complications were reversible, especially temporary polyoma viremia within normal renal function, and 2 episodes of urosepsis. No relapse of her pretransplant episode of atypical haemolytic uremic syndrome occurred posttransplant. Her child is in good health at the age of 12 months without any malformations. CONCLUSIONS This case suggests that pregnancy after SPK under LCPT is feasible. Further studies are needed to expand the empirical knowledge surrounding tacrolimus.

Background: Simultaneous pancreas kidney transplantation (SPK) is the best therapeutic option for patients with diabetes mellitus type 1 and end-stage renal disease. Recently, donor organ extraction time has been shown to affect kidney and liver graft survival. This study aimed to assess the effect of pancreas donor extraction time on graft survival and postoperative complications.Methods: We retrospectively analyzed all pancreas transplants performed in two Eurotransplant centers. The association of pancreas extraction time with pancreas graft survival was analyzed by a Cox proportional hazards regression analysis after 3 months, 1 and 5 year. Besides, the effect of pancreas extraction time on the incidence of severe postoperative complications was analyzed.Results: A total of 317 pancreas transplants were included in this study. Death-censored pancreas graft survival was 85.7% after one year and 76.7% after five years. Median pancreas donor extraction time was 64 min [IQR: 52-79 min]. After adjustment for potential confounders, death censored graft survival after 30 days (HR 1.01, 95% CI 0.9-1.03 (p = 0.23), 1 year (HR 1.01, 95% CI 0.99-1.03 (p = 0.22) and 5 years (HR 1.00, 95% CI 0.99-1.02 (p = 0.57) was not associated with pancreas donor extraction time. However, extraction time was significantly associated with a higher incidence of Clavien-Dindo >3 complications compared to Clavien-Dindo 1 + 2 complications: OR 1.012, 95% CI 1.00-1.02 (p = 0.039).Conclusions: Our findings suggest that although no effect on graft survival was found, limiting pancreas extraction time can have a significant impact on lowering postoperative complications.

Background Given the susceptibility of organs to ischaemic injury, alternative preservation methods to static cold storage (SCS), such as normothermic machine perfusion (NMP) are emerging. The aim of this study was to perform a comparison between NMP and SCS in liver transplantation with particular attention to bile duct lesions. Methods The outcomes of 59 consecutive NMP-preserved donor livers were compared in a 1 : 1 propensity score-matched fashion to SCS control livers. Postoperative complications, patient survival, graft survival and bile duct lesions were analysed. Results While patients were matched for cold ischaemia time, the total preservation time was significantly longer in the NMP group (21 h versus 7 h, P Conclusion The use of NMP allowed for a significantly prolonged organ preservation with a lower rate of observed ischaemic-type bile duct lesions.

Background The relationship between nutrition and liver disease is relevant for the outcome after surgery. Patients with liver cirrhosis characteristically show protein-energy malnutrition with decreased levels of branched-chain amino acids (BCAA) and increased levels of aromatic amino acids. Materials and Methods We conducted a prospective controlled clinical trial including 57 patients after liver transplantation or major liver resection surgery in order to test the effect of early postoperative nutrition on the outcome and nutrition profile of these patients. The test group received a dietetic program composed of ingredients naturally rich in BCAA (BCAA group), and the control group received standard hospital meals. Patient survival, liver function tests, subjective well-being, and a nutritional status including amino acid profiles were analyzed immediately and 14 days after major liver surgery (secondary end points). General health and well-being were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (primary end point). Results In-depth analysis of amino acid profiles was performed for patients undergoing liver resection (n = 21) and liver transplantation (n = 36). Interestingly, amino acid profiles did not correlate with body mass index or the Model for End-Stage Liver Disease score. Patients scheduled for liver transplantation showed significantly lower levels of BCAA pretransplant compared to patients undergoing liver resection. Patients in the liver resection subgroup were more likely to benefit from the BCAA cuisine in terms of significantly higher food intake and subjective rating. The clinical liver function tests, however, did not show statistical difference between the BCAA group and the control group in the examination period of 14 days. Conclusion Our specifically designed BCAA-enriched diet resulted in greater patient satisfaction and compliance with nutrition. A larger trial or longer-term follow-up may be required to identify an effect on survival, recovery, surgical complications, protein profiles, and amino acid profiles.

With a later onset of diabetes complications and thus increasing age of transplant candidates, many centers have extended upper age limits for pancreas transplantation. This study investigates the effect of recipient and donor age on outcomes after pancreas transplantation.We retrospectively analyzed 565 pancreas transplants performed at two Eurotransplant centers. The cohort was split at a recipient and donor age of 50 and 40 years, respectively. Median recipient age in old patients (≥50 years; 27.2%) was 54 years and 40 years in young patients (

It has been hypothesized that transplanting simultaneous pancreas kidney (SPK) grafts from donors with a history of cardiac arrest and cardiopulmonary resuscitation (CACPR) leads to inferior posttransplant outcomes due to organ hypoperfusion during cardiac arrest and mechanical trauma during resuscitation. Using Scientific Registry of Transplant Recipients data, we identified 13 095 SPK transplants from 2000-2018, of which 810 (6.2%) were from donors with a history of CACPR. After inverse probability of treatment weighting on donor and recipient characteristics, we found that 1-, 5-, and 10-year patient (CACPR: 96.4%, 89.9%, and 78.9%; non-CACPR: 96.3%, 88.9%, and 76.0%; P = .3), death-censored pancreas graft survival (CACPR: 89.3%, 82.7%, 75.0%; non-CACPR: 89.9%, 82.7%, 76.3%; P = .7), and death-censored kidney graft survival (CACPR: 97.0%, 89.5%, 78.2%; non-CACPR: 96.9.9%, 88.7%, 80.0%; P = .4) were comparable between the two groups. There were no differences in the risk of pancreatitis (CACPR: 2.9%, non-CACPR: 2.4%; weighted OR = 0.74 1.22 2.02 ; P = .4), anastomotic leak (CACPR: 1.6%, non-CACPR: 2.0%; weighted OR = 0.54 1.02 1.93 ; P > .9), or median length of hospital stay (CACPR: 8 days, non-CACPR: 9 days; P = .6) for recipients of CACPR vs non-CACPR donors. Our findings suggest that CACPR donors could be used to expand the SPK donor pool without compromising short- or long-term outcomes.

Background Normothermic machine perfusion (NMP) bears the potential for significant prolongation of liver preservation before transplantation. Although safety and feasibility have been recently published, no data are available describing the significant challenges of establishing NMP programs outside clinical studies. We herein present our experience and propose a multidisciplinary approach for liver NMP in the clinical routine. Methods In February 2018, liver NMP was introduced for routine use in marginal organs, logistic challenges, and complex recipients at our institution. In a multidisciplinary effort among transplant coordinators, perfusionists, transplant surgeons, anesthesia, nurses, blood bank as well as laboratory staff, a clinical routine was established and 34 NMP cases were performed without critical incidents or organ loss. Results Nine livers were discarded due to poor organ quality and function observed during NMP. Twenty-five livers were successfully transplanted after preservation of up to 38 h. The extended criteria donors rate was 100% and 92% in discarded and transplanted livers, respectively. Nighttime procedures and parallel transplantations were eventually omitted. Graft and patient survival was 88% at 20 mo. No cholangiopathy was observed despite the use of extended criteria donor organs in 92% of cases. Conclusions NMP in a multidisciplinary approach enables a safe prolongation of liver preservation and overnight organ care. A first field test of NMP indicates safety and benefit of this approach.

Normothermic machine perfusion (NMP) allows for ex vivo viability and functional assessment prior to liver transplantation (LT). Hyperspectral imaging represents a suitable, non-invasive method to evaluate tissue morphology and organ perfusion during NMP. Liver allografts were subjected to NMP prior to LT. Serial image acquisition of oxygen saturation levels (StO2), organ hemoglobin (THI), near-infrared perfusion (NIR) and tissue water indices (TWI) through hyperspectral imaging was performed during static cold storage, at 1h, 6h, 12h and at the end of NMP. The readouts were correlated with perfusate parameters at equivalent time points. Twenty-one deceased donor livers were included in the study. Seven (33.0%) were discarded due to poor organ function during NMP. StO2 (p < 0.001), THI (p < 0.001) and NIR (p = 0.002) significantly augmented, from static cold storage (pre-NMP) to NMP end, while TWI dropped (p = 0.005) during the observational period. At 12–24h, a significantly higher hemoglobin concentration (THI) in the superficial tissue layers was seen in discarded, compared to transplanted livers (p = 0.036). Lactate values at 12h NMP correlated negatively with NIR perfusion index between 12 and 24h NMP and with the delta NIR perfusion index between 1 and 24h (rs = −0.883, p = 0.008 for both). Furthermore, NIR and TWI correlated with lactate clearance and pH. This study provides first evidence of feasibility of hyperspectral imaging as a potentially helpful contact-free organ viability assessment tool during liver NMP.

Normothermic machine perfusion (NMP) has become a clinically established tool to preserve livers in a near-physiological environment. However, little is known about the predictive value of perfusate parameters toward the outcomes after transplantation.Fifty-five consecutive NMP livers between 2018 and 2019 were included. All of the livers were perfused on the OrganOx metra device according to an institutional protocol. Transplant and perfusion data were collected prospectively.Forty-five livers were transplanted after NMP. Five livers stem from donors after circulatory death and 31 (68.9%) from extended criteria donors. Mean (SD) cold ischemia time was 6.4 (2.3) h; mean (SD) total preservation time was 21.4 (7.1) h. Early allograft dysfunction (EAD) occurred in 13 of 45 (28.9%) patients. Perfusate aspartate aminotransferase (P = 0.008), alanine aminotransferase (P = 0.006), lactate dehydrogenase (P = 0.007) and their development over time, alkaline phosphatase (P = 0.013), and sodium (P = 0.016) correlated with EAD. Number of perfusate platelets correlated with cold ischemia time duration and were indicative for the occurrence of EAD. Moreover, von Willebrand Factor antigen was significantly higher in perfusates of EAD livers (P 0.001), and Δ von Willebrand factor antigen correlated with EAD. Although perfusate lactate and glucose had no predictive value, EAD was more likely to occur in livers with lower perfusate pH (P = 0.008). ΔPerfusate alkaline phosphatase, Δperfusate aspartate aminotransferase, Δperfusate alanine aminotransferase, and Δperfusate lactate dehydrogenase correlated closely with model for early allograft function but not liver graft assessment following transplantation risk score. Bile parameters correlated with extended criteria donor and donor risk index.Biomarker assessment during NMP may help to predict EAD after liver transplantation. The increase of transaminases and lactate dehydrogenase over time as well as platelets and vWF antigen are important factors indicative for EAD.

Chronic immunosuppression is associated with an increased risk of malignancy. The main objective of this study is to evaluate the incidence and effect of post-transplant malignancies (PTMs) following pancreas transplantation. The 348 first pancreas transplants performed between 1985 and 2015 were retrospectively analyzed in this study. Incidences of PTMs, as well as patient and graft survival, were evaluated. Out of 348 patients, 71 (20.4%) developed a PTM. Median time to diagnosis was 130 months. Thirty-six patients (50.7%) developed skin cancers (four patients with melanoma, 32 with NMSCs). Solid organ malignancy occurred in 25 (35.2%), hematologic malignancy in ten patients (14.1%). Affected patients were transplanted earlier [2000 (IQR 1993−2004) vs. 2003 (IQR 1999−2008), p &lt, 0.001]. No differences in induction therapy were seen, both groups demonstrated comparable patient and graft survival. Pancreas transplant recipients with solid organ and hematologic malignancies had a three- and six-fold increased hazard of death compared to those with skin cancers [aHR 3.04 (IQR 1.17–7.91), p = 0.023, aHR 6.07 (IQR 1.87–19.71), p = 0.003]. PTMs affect every fifth patient following pancreas transplantation. Skin cancers are the most common malignancies accounting for 50% of all PTMs. These results underscore the importance of close dermatologic follow-up.

In contrast to well-published data with acceptable long-term results in large cohorts of single renal transplant recipients aged >65 y (lit.), combined pancreas-kidney transplantation in recipients >50 y is discussed controversially. Some groups have identified older recipients as a high-risk group, demonstrating decreased patient and graft survival in this population.1-4 Nevertheless, several centers have reported results for pancreatic transplantation in older patients as being comparable to those for younger recipients with the age cutoff ranging from 50 to 60 y.5-10 At our center, we have long-term experience with a total of 655 pancreas transplants performed between 1979 and August 2020, whereby 21 recipients were over 60 y of age; the oldest was age 69 and in remarkably good general condition with good mental adherence and a strong wish to undergo simultaneous kidney-pancreas transplantation (SPK). We retrospectively analyzed patient, pancreas, and kidney graft survival, graft function, and complications at month 38 posttransplant.

Summary 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.

BACKGROUND Sarcopenia is an established risk factor predicting survival in chronically ill and trauma patients. We herein examine the assessment and clinical implication of sarcopenia in liver transplantation (LT). METHODS Computerized tomography scans from 172 patients waitlisted for LT were analyzed by applying 6 morphometric muscle scores, including 2 density indices (psoas density [PD] and skeletal muscle density [SMD]) and 4 scores based on muscle area (total psoas area, psoas muscle index, skeletal muscle area, and skeletal muscle index). RESULTS The prevalence of sarcopenia in our cohort ranged from 7.0% to 37.8%, depending on the score applied. Only sarcopenia as defined by the density indices PD and SMD (but not total psoas area, psoas muscle index, skeletal muscle area, or skeletal muscle index) revealed clinical relevance since it correlates significantly with postoperative complications (≥Grade III, Clavien-Dindo classification) and sepsis. Furthermore, sarcopenia predicted inferior patient and graft survival, with low muscle density (PD

The aim of our prospective clinical trial was to test a tissue staining technique (real-time confocal analysis [RTCA]) as a rapid assessment tool for donor kidney quality and function in human kidney transplantation.Tools for objective graft tissue viability assessment before kidney transplantation are lacking. RTCA has recently been established and tested in a pilot study using rodent kidneys.RTCA was performed in kidney biopsies stained with SYTO16/PI and WGA. A score between -3 (100% nonviable) and +3 (100% viable) describes the sum of viable cells divided by the number of nonviable cells per examined area (glomerulus, proximal, and distal tubules). The primary study endpoint was the delayed graft function (DGF).Seventy-one kidney transplant recipients were transplanted. The median recipient and donor age were 58.5 and 57 years, respectively. Cold ischemia time was 13.6 ± 4.7 hours; anastomosis time was 30.8 ± 8.7 minutes (mean ± SD). Overall, 23 (33.8%) patients developed DGF. The RTCA score was significantly lower in kidneys developing DGF -0.43 ± 1.78 versus no DGF 0.91 ± 2.17, P = 0.01. The Remuzzi score did not differ between DGF and no DGF, P = 0.13. Remuzzi score and RTCA score correlate inversely significantly; P = 0.004. In the multivariate analysis, solely RTCA score was revealed as a significant independent factor predicting DGF; P = 0.015, Wald = 5.95, odds ratio = 0.72, 95% confidence interval = 0.55 to 0.94.Our data demonstrate that RTCA is feasible and clinically meaningful. The RTCA score predicts DGF and is a valid option to be applied in renal transplantation.

Despite technical advances in surgical resection and postoperative management of the pancreas, surgical procedures of the pancreas are associated with a high rate of complications, resulting in a relevant morbidity and mortality. Early diagnosis and management of complications associated with pancreas surgery is mandatory, favoring a multidisciplinary approach. Interventional radiology offers minimal invasive techniques to manage post-surgical complications. These procedures are highlighted in this review, including percutaneous drainage of fluid collections, percutaneous transhepatic biliary interventions, arterial embolisation and fistula embolisation. Post-surgical complications of pancreatic surgery are effectively managed by radiological procedures, offering a feasible and safe treatment with low morbidity rates. Accurate patient selection is key to an effective management of clinical situations where these interventions represent the first line approach. Radiologic procedures allow for minimal invasive treatment of postoperative complications after pancreatic surgery, reducing the time of hospitalization and the time of recovery.

Graft vasculopathy is the main feature of chronic rejection in organ transplantation, with oxidative stress being a major trigger. Inflammation-associated prooxidant processes may be controlled by antioxidants; however, interference with redox-regulated mechanisms is a complex endeavor. An essential feature of the cellular immune response is the acceleration of tryptophan (Trp) breakdown, leading to the formation of several bioactive catabolites. Long-term activation of this immunobiochemical pathway contributes to the establishment of a tolerogenic environment, thereby supporting allograft survival. Herein, the impact of the antioxidant sodium sulfite on the development of graft vasculopathy was assessed in murine aortic transplantation. Allogeneic (BALB/c to C57BL/6) heterotopic murine aortic transplantations were performed. Animals were left untreated or were treated with 10 μl of 0.1 M, of 0.01 M sodium sulfite, or of 0.1 M sodium sulfate, intraperitoneally once/day, until postoperative day (POD) 100. Grafts were assessed by histology, immunohistochemistry, and adhesion molecule gene expression. Serum concentrations of tryptophan and its catabolite kynurenine (Kyn) were measured. On day 100, graft vasculopathy was significantly increased upon treatment with 0.1 M sodium sulfite, compared to allogeneic untreated controls (p=0.004), which correlated with a significant increase ofα-smooth-muscle-actin, Vcam-1, and P-selectin. Serum Kyn concentrations increased in the allogeneic control group over time (p<0.05,POD≥50), while low-dose sodium sulfite treatment (0.01 M) treatment resulted in a decrease in Kyn levels over time (p<0.05,POD≥10), compared to the respective baselines (p<0.05). Longitudinal analysis of serum metabolite concentrations in the different treatment groups further identified an overall effect of sodium sulfite on Kyn concentrations. Antioxidative treatment may result in ambivalent consequences. Our data reveal that an excess of antioxidants like sodium sulfite can aggravate allograft vasculopathy, which further highlights the challenges associated with interventions that interfere with the complex interplay of redox-regulated inflammatory processes.

Despite clear advances in decreasing postoperative mortality below 4% after pancreatic resections in experienced centres, specific morbidity according to standardized definitions still remains high. While some recent multicentre studies have reported on complications after pancreatic surgery in Austria, detailed outcome data from single high-volume centres over longer time-periods are scarce. This study provides an in-depth picture of patient characteristics, indications, morbidity and mortality after pancreatic surgery in an Austrian tertiary referral centre. All patients undergoing curative intent resection between 2010 and 2017 at the Medical University of Innsbruck were evaluated. Patient characteristics and procedural details, overall and specific complications including postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE) and post-pancreatectomy haemorrhage (PPH) rates according to accepted definitions are reported. Outcomes after pancreatic head resections, distal pancreatectomy and other types of resections are compared. Factors associated with severe and overall morbidity are evaluated by logistic regression modelling. A total of 343 patients underwent pancreatic resection, at a median of 64 years (53% males). Most common indications were pancreatic or bile-duct carcinoma (52%), benign/precursor lesions (22%) and neuroendocrine tumours (11%). The 90-day mortality was 2%; 90-day overall/severe morbidity was 66.2%/22.4%. POPF grade B/C occurred in 19.3%, PPH in 17.5% and DGE in 14.3%. Male gender was associated with severe morbidity, body mass index and procedures other than distal resections with overall morbidity. POPF and PPH were major causes for relaparotomy. Pancreatic resections in our centre are performed with low mortality, although morbidity still represents a relevant clinical problem, especially POPF and PPH.

BACKGROUND Early biliary complications (EBC) constitute a burden after pediatric liver transplantation frequently requiring immediate therapy. We aimed to assess the impact of EBC on short- and long-term patient and graft survival as well as post-transplant morbidity. METHODS We analyzed 121 pediatric liver transplantations performed between 1984 and 2019 at the Medical University of Innsbruck for the occurrence of early (

BACKGROUND In an experimental murine liver clamping model, we aimed to investigate the efficacy of real-time confocal microscopy (RCM) in assessing viability of steatotic livers in comparison to standard assessment tools, including histopathological evaluation. METHODS C57Bl/6 mice were subjected to a methionine-choline-deficient diet causing nonalcoholic fatty liver disease or to Lieber DeCarli diet causing ethanol-induced liver injury. Untreated animals served as controls. Liver biopsies were analyzed following challenge with 45 min of warm ischemia time and either 4 h of reperfusion or 24 h of cold storage. Organ quality assessment was performed at defined time points by RCM, histological staining, measurement of serum alanine aminotransferase activity, and expression analyses of proinflammatory cytokines. Additionally, survival analysis was performed. RESULTS Cold as well as warm ischemia time resulted in a significant decrease in cell viability when compared with naive livers as well as nonischemic-challenged steatotic livers (P

BACKGROUND/OBJECTIVES:After years of growth in many pancreas transplant programs, UNOS has reported declining transplant numbers in the USA. This precipitating trend urges for an evaluation of the transplant numbers and scientific productivity in the Eurotransplant region and the UK.METHODS:We performed a trend analysis of pancreas transplantation rates, between 1997 and 2016, adjusting for changes in population size, and an analysis of scientific publications in this field. We used information from the UNOS, Eurotransplant, and UK transplant registry and bibliometric information from the Web of Science database.RESULTS:Between 2004 and 2016 there was an average annual decline in pancreas transplantation rates per million inhabitants of 3.3% in the USA and 2.5% in the Eurotransplant region. In the UK, transplant numbers showed an average annual decline of 1.0% from 2009 to 2016. Publications in Q1 journals showed an annual change of -2.1% and +20.1%, before 2004, and a change of -3.8% and -5.5%, between 2004 and 2016, for USA and Eurotransplant publications, respectively.CONCLUSIONS:Adjusting pancreas transplantation rates for changes in population size showed a clear decline in transplant numbers in both the USA and Eurotransplant region, with first signs of decline in the UK. Following this trend, the number of scientific publications in this field have declined worldwide.

Retrospective analysis of the long-term results of a randomized controlled trial comparing alemtuzumab (ALEM) and antithymocyte globulin (ATG) as induction therapy in simultaneous pancreas-kidney transplantation (SPK) to address individualized long-term immunosuppression. Between 2006 and 2010 a total of 30 SPKs were randomized to treatment with ALEM plus tacrolimus (TAC) monotherapy (Group A, n=14) versus ATG induction plus TAC, mycophenolate mofetil (MMF) and steroids (Group B, n=16), followed by individualized long-term immunosuppression. We here present the long-term results for graft survival, graft function, and major complications. The 9-year patient survival rates in Groups A and Group B were 92.9% and 86.7% respectively; pancreas graft survival was 75.0% and 65.0% respectively; renal graft survival was 83.1% and 93.8% respectively. Long-term graft function was excellent with a creatinine of 1.5 mg/dL and 1.4 mg/dL, fasting glycemia of 104 mg/dL and 102 mg/dL, hemoglobin (Hb) A1c of 5.4 g% and 5.6 g% in Group A and Group B, respectively. Major complications were comparable in both groups. Good long-term results for patient, pancreas graft and kidney graft survival were achieved in both groups with individually adapted maintenance immunosuppression. ALEM is a valid induction therapy.

Primary focal segmental glomerulosclerosis (FSGS) recurs in up to 55% of patients after kidney transplantation. Herein we report the successful management of recurrent FSGS. A 5‐year‐old boy with primary FSGS received a deceased donor renal transplant. Immediate and fulminant recurrence of FSGS caused anuric graft failure that was resistant to plasmapheresis and rituximab. After exclusion of structural or immunologic damage to the kidney by repeated biopsies, the allograft was retrieved from the first recipient on day 27 and transplanted into a 52‐year‐old second recipient who had vascular nephropathy. Immediately after retransplantation, the allograft regained function with excellent graft function persistent now at 3 years after transplant. After 2 years on hemodialysis, the boy was listed for kidney retransplantation. To prevent FSGS recurrence, pretreatment with ofatumumab was performed. Nephrotic range proteinuria still occurred after the second transplantation, which responded, however, to daily plasma exchange in combination with ofatumumab. At 8 months after kidney retransplantation graft function is good. The clinical course supports the hypothesis of a circulating permeability factor in the pathogenesis of FSGS. Successful ofatumumab pretreatment implicates a key role of B cells. Herein we provide a description of successful management of kidney failure by FSGS, carefully avoiding waste of organs., Successful management of recurrent primary focal segmental glomerulosclerosis after kidney transplantation includes retransplantation of an allograft that failed in the first recipient due to disease recurrence into a second recipient and ofatumumab pretreatment before kidney retransplantation in the patient with fulminant recurrence of focal segmental glomerulosclerosis in the first graft.

Background Pancreas retransplantation is still a controversial option after loss of a pancreatic graft. This article describes the experience of pancreas retransplantation at a high‐volume centre. Methods This was a retrospective observational study of all pancreas retransplantations performed in a single centre between 1997 and 2013. Pancreatic graft loss was defined by the return to insulin dependence. Risk factors for graft loss as well as patient and graft survival were analysed using logistic and time‐to‐event regression models. Results Of 409 pancreas transplantations undertaken, 52 (12·7 per cent) were identified as pancreas retransplantations. After a median follow‐up of 65·0 (range 0·8–174·3) months, 1‐ and 5‐year graft survival rates were 79 and 69 per cent respectively, and 1‐ and 5‐year patient survival rates were 96 and 89 per cent. During the entire follow‐up, 22 grafts (42 per cent) were lost. Patient survival was not associated with any of the donor‐ or recipient‐related factors investigated. Five‐year graft survival was better after simultaneous kidney–pancreas retransplantation than pancreas retransplantation alone: 80 per cent (16 of 20) versus 63 per cent (20 of 32) (P = 0·226). Acute rejection (odds ratio 4·49, 95 per cent c.i. 1·59 to 12·68; P = 0·005) and early surgical complications (OR 3·29, 1·09 to 9·99, P = 0·035) were identified as factors with an independent negative effect on graft survival. Conclusion Pancreas retransplantation may be considered for patients whose previous graft has failed., Good outcome in selected patients

Summary Background Owing to remarkable improvements of surgical techniques and associated specialities, liver surgery has become the standard of care for hepatocellular carcinoma and cholangiocarcinoma. Although applied with much greater safety, hepatic resections for primary liver tumours remain challenging and need to be integrated in a complex multidisciplinary treatment approach. Methods This literature review gives an update on the recent developments regarding basics of open and laparoscopic liver surgery and surgical strategies for primary liver tumours. Results Single-centre reports and multicentre registries mainly from Asia and Europe dominate the surgical literature on primary liver tumours, but the numbers of randomized trials are slowly increasing. Perioperative outcomes of open liver surgery for hepatocellular and cholangiocellular carcinoma have vastly improved over the last decades, accompanied by some progress in terms of oncological outcome. The laparoscopic approach is increasingly being applied in many centres, even for patients with underlying liver disease, and may result in decreased morbidity. Liver transplantation represents a cornerstone in the treatment of early hepatocellular carcinoma and is indispensable to achieve long-term survival. In contrast, resection remains the gold standard for cholangiocarcinoma in most countries, but interventional techniques are on the rise. Conclusion Liver surgery for primary tumours is complex, with a need for high expertise in a multidisciplinary team to achieve acceptable outcomes. Technical developments and clinical stratification tools have optimized individual care, but further improvements in oncological survival will likely require enhanced pre- and postoperative systemic and local treatment options.

Introduction/Background To describe accurately the oncological outcomes after hepatic resection (HR) in recurrent ovarian carcinoma (ROC) evaluating clinic-pathological variables and mutational status of BRCA1/2. Although HR is considered a challenging situation in ROC patients, assessment of BRCA1/2 mutational status seems to have a relevant clinical value to guide surgical therapy. Methodology Patients who underwent HR for ROC at the Catholic University of Rome, between June 2012 and October 2017 were included. Exclusion criteria were represented by extra-abdominal disease and presence of diffuse peritoneal carcinomatosis requiring more than 2 bowel resections. Details relative to HR were collected and BRCA analysis was performed. Predictive factors for of post-relapse progression free survival (PHR-PFS)were assessed by univariate analyses using Cox-proportional hazard regression models. Results Thirty-four patients undewent HR within secondary cytoreductive surgery (SCS). Six patients (17.6%) presented with hepatic relapse only, while the remaining 28 patients (82.4%) had concomitant extra-hepatic disease. In the whole series, the 3-yr PHR-PFS was 49.1% and the 3-yr progression free survival overall survivalwas 72.9%. Univariate analysis of variables conditioning PHR-PFS showed that only BRCA mutational status played a statistically significant favourable role: the 3-yr PHR-PFS rate was 81.0% in BRCA mutated patient compared to15.2% in wild type ones (p value: 0.001). Conclusion Our clinical analyses suggest that in ROC patients with liver disease the assessment of BRCA mutational status can help to select patients elegible for SCS. Disclosure Nothing to disclose.

Background Several studies in solid organ transplantation have shown a correlation between donor and recipient sex mismatch and risk of graft loss. In this study, we aimed to analyze the impact of donor and recipient sex matching on patient and pancreas graft survival in a large single‐center cohort. Methods We retrospectively analyzed all first simultaneous pancreas‐kidney transplants performed between 1979 and 2017 at the Medical University of Innsbruck. Results Of 452 patients, 54.6% (247) received a sex‐matched transplant. Patient survival (P = .86), death‐censored pancreas graft survival (dcPGS, P = .26), and death‐censored kidney graft survival (dcKGS, P = .24) were similar between the sex‐matched and sex‐mismatched groups. Patient survival and dcPGS at 1, 5, and 15 years were 95.9%, 90.0%, and 62.1% and 86.1%, 77.1%, and 56.7% in the sex‐matched group and 93.6%, 86.2%, and 62.4% and 83.1%, 73.3%, and 54.3% in the sex‐mismatched group. Sex matching led to a lower odds of severe postoperative complications (41.2% vs 49.0%; OR 0.57, 95%CI 0.33‐0.97; P = .038); however, no increased odds of other adverse postoperative outcomes was detected. Conclusion Our study demonstrates that sex matching reduced the odds of postoperative complications but did not impact other early and late outcome parameters in our cohort.

Etwa 10 % aller entfernten Polypen erweisen sich als kolorektale Fruhkarzinome. Deren Management ist v. a. vor dem Hintergrund der Vorsorgekoloskopie von besonderer Bedeutung. Die Therapie richtet sich zuvorderst nach histopathologischen Kriterien. So korreliert die Eindringtiefe des Karzinoms in die Submukosa direkt mit der Wahrscheinlichkeit von Lymphknotenmetastasen. Die Therapie reicht von der alleinigen endoskopischen Abtragung im Falle einer Niedrigrisikosituation bis hin zum radikalen chirurgischen Eingriff nach onkologischen Kriterien in Hochrisikosituationen. Die Abtragung erfolgt mittels Schlingenabtragung, endoskopischer Mukosaresektion oder endoskopischer Submukosadissektion. Alle Methoden zielen auf eine vollstandige Resektion ab – die lokale Exzision eines kolorektalen Fruhkarzinoms sollte stets kritisch gegen einen radikalen chirurgischen Eingriff abgewogen werden. Das Einhalten klarer Algorithmen erleichtert dabei die Weichenstellung fur eine stadiengerechte Therapie.
