Clinical practice has inadvertently changed after the COVID-19 pandemic and currently the need to provide sustainable surgical services is more pressing than ever. The National Health Service has committed to a long-term efficient plan to reduce carbon footprint but there is no detailed plan for surgical practice, the domain that contributes the most to hospital-derived pollution. A series of consecutive steps and measures ought to be taken, starting from a hybrid approach quantifying surgically attributed carbon footprint. Then, a variety of suggested measures can be widely discussed and accordingly applied on a wider or more local level. Appropriate training should always precede implementing new practices to ensure that staff is familiar with these. These measures cover a broad range and should be arranged on a patient-centred basis from preoperative preconditioning to an effective follow-up. The need for more intense research and implementation of enhanced recovery protocols is widely discussed. Also, the necessity of green research and reinvestment of materials and resources is highlighted. A change of philosophy from a cradle-to-grave approach to a repurposing approach is suggested. We are confident that a new era is dawning in surgical practice and teamwork is the key for providing greener surgical services.

The SEVE project (Surgical Expertise Validity Evaluation) is a collaborative effort of the AEC (Spanish Association of Surgeons) and the Section of Surgery of the European Union of Medical Specialists (UEMS) that aims to develop a model and an on line application that can be used to evaluate surgical complications. The aim is to identify the optimal results that can be obtained in each intervention, in order to present them as a reference for our usual practice (benchmarking).

Background Hypothermic Machine Perfusion (HMP) is a well-established method for deceased donor kidney preservation. Normothermic Machine Perfusion (NMP) might offer similar or greater advantages. We compared the two methods in an ex vivo perfusion model using 34 porcine kidneys. Methods Thirty kidneys were stored on ice for 24h before undergoing 4h of HMP (n=15) or NMP (n=15) followed by 2h of normothermic ex vivo reperfusion with whole blood. Four kidneys underwent 28h of cold static storage (CSS) followed by 2h of normothermic ex vivo reperfusion. During the 2 hours of normothermic ex vivo reperfusion perfusate flow rates, urinary output and oxygen consumption rates were compared between all groups. Results Porcine kidneys after HMP showed significantly higher urinary output- (5.31ml/min±2.06ml/min vs. 2.44ml/min±1.19ml/min, p=0.002), oxygen consumption- (22.71±6.27ml/min vs. 11.83±1.29ml/min, p=0.0016) and perfusate flow rates (46.24±12.49ml/min vs. 26.16±4.57ml/min, p=0.0051) than kidneys after NMP. Tunnel staining of tissue sections showed significantly higher rates of apoptosis in kidneys after NMP (p=0.027). Conclusions In our study, the direct comparison of HMP and NMP kidney perfusion in a translational model demonstrated superiority of HMP, however further in vivo studies would be needed to validate those results.

The cost of clinical negligence claims continues to rise, despite efforts to reduce this now ageing burden to the National Health Service (NHS) in England. From a welfarist perspective, reforms are needed to reduce avoidable harm to patients and to settle claims fairly for both claimants and society. Uncertainty in the estimation of quanta of damages, better known as financial settlements, is an important yet poorly characterised driver of societal outcomes. This reflects wider limitations to evidence informing clinical negligence policy, which has been discussed in recent literature. There is an acute need for practicable, evidence-based solutions that address clinical negligence issues, and these should complement long-standing efforts to improve patient safety. Using 15 claim cases from one NHS Trust between 2004 and 2016, the quality of evidence informing claims was appraised using methods from evidence-based medicine. Most of the evidence informing clinical negligence claims was found to be the lowest quality possible (expert opinion). The extent to which the quality of evidence represents a normative deviance from scientific standards is discussed. To address concerns about the level of uncertainty involved in deriving quanta, we provide five recommendations for medico-legal stakeholders that are designed to reduce avoidable bias and correct potential market failures.

Objectives: International guidelines recommend the use of autogenous vascular access. Where suitable superficial veins are unavailable deeper veins may be used as an option. In most cases, basilic veins are used when cephalic veins are unavailable; arteriovenous fistulas using the brachial vein from the deep venous network are rare. Therefore, the purpose of the present study was to conduct a systematic review of the available literature evaluating the use of the brachial vein in arteriovenous fistulas. Methods: Systematic literature search of electronic databases in accordance with PRISMA was conducted. The primary outcomes of this study were primary and secondary patency rates for brachial vein arteriovenous fistulas; the secondary outcomes were the rates of access thrombosis, steal syndrome, pseudo-aneurysm and infection. Results: The 1-year primary, assisted, and secondary patency was recorded at (24%–77%), (45%–85%) and (45%–96%), respectively. The 2-year primary, assisted and secondary patency rate was recorded at (12%–46%), (19%–75%) and (19%–92%), respectively. However, the consistency regarding the reports and definitions used were highly variable. The incidence rate of infection, thrombosis and steal syndrome was 5% (0%–12%), 15.9% (9.5%–35%) and 3% (2%–6%), respectively. Conclusion: Available studies support the use of brachial veins as a reliable access option in patients with non-accessible superficial veins where an autologous option is required.

Enhanced recovery after surgery (ERAS) protocols are designed to reduce medical complications, the length of hospital stays (LoS), and healthcare costs. ERAS is considered safe and effective for kidney transplant (KTx) surgery. KTx recipients are often frail with multiple comorbidities. As these patients follow an extensive diagnostic pathway preoperatively, the ERAS protocol can ideally be implemented at this stage. Small singular changes in a long perioperative pathway can result in significant positive outcomes. We have investigated the current evidence for an ERAS pathway related to anaesthetic considerations in renal transplant surgery for adult recipients.

Background Living kidney donation risk is likely to differ according to donor’s demographics. We aimed to analyse the effects of age, sex, body mass index (BMI) and ethnicity. Methods A systematic review and meta-analysis was undertaken of the effects of preoperative patient characteristics on donor kidney function outcomes, surgical complications, and hypertension. Results 5129 studies were identified, of which 31 met the inclusion criteria, mainly from the USA and Europe. The estimated glomerular filtration rate (eGFR) in donors aged over 60 years was a mean of 9.54 ml per min per 1.73 m2 lower than that of younger donors (P Conclusion Obesity and male sex were associated with inferior outcomes. Older donors (aged over 60 years) have a larger eGFR decline than younger donors, and African donors have a higher incidence of ESRD than Caucasians.

This article gives a personal, historical, account of the impact of the COVID-19 pandemic on transplantation services. The content is based on discussions held at two webinars in November 2020, at which kidney transplantation experts from prestigious institutions in Europe and the United States reflected on how the pandemic affected working practices. The group discussed adaptations to clinical care (i.e., ceasing, maintaining and re-starting kidney transplantations, and cytomegalovirus infection management) across the early course of the pandemic. Discussants were re-contacted in October 2021 and asked to comment on how transplantation services had evolved, given the widespread access to COVID-19 testing and the roll-out of vaccination and booster programs. By October 2021, near-normal life and service delivery was resuming, despite substantial ongoing cases of COVID-19 infection. However, transplant recipients remained at heightened risk of COVID-19 infection despite vaccination, given their limited response to mRNA vaccines and booster dosing: further risk-reduction strategies required exploration. This article provides a contemporaneous account of these different phases of the pandemic from the transplant clinician’s perspective, and provides constructive suggestions for clinical practice and research.

Ethnic disparities in the outcomes after simultaneous pancreas kidney (SPK) transplantation still exist. The influence of ethnicity on the outcomes of pancreas transplantation in the UK has not been reported and hence we aimed to investigate our cohort. A retrospective analysis of all pancreas transplant recipients (n = 171; Caucasians = 118/Black Asian Ethnic Minorities, BAME = 53) from 2006 to 2020 was done. The median follow-up was 80 months. Patient & pancreas graft survival, rejection rate, steroid free maintenance rate, HbA1c, weight gain, and the incidence of secondary diabetic complications post-transplant were compared between the groups. p < 0.003 was considered significant (corrected for multiple hypothesis testing). Immunosuppression consisted of alemtuzumab induction and steroid free maintenance with tacrolimus and mycophenolate mofetil. Pancreas graft & patient survival were equivalent in both the groups. BAME recipients had a higher prevalence of type-2 diabetes mellitus pre-transplant (BAME = 30.19% vs. Caucasians = 0.85%, p < 0.0001), and waited for a similar time to transplantation once waitlisted, although pre-emptive SPK transplantation rate was higher for Caucasian recipients (Caucasians = 78.5% vs. BAME = 0.85%, p < 0.0001). Despite equivalent rejections & steroid usage, BAME recipients gained more weight (BAME = 7.7% vs. Caucasians = 1.8%, p = 0.001), but had similar HbA1c (functioning grafts) at 3-,12-, 36-, and 60-months post-transplant.

Contains fulltext : 229465.pdf (Publisher’s version ) (Closed access) BACKGROUND: Deceased donor kidneys are preserved in cold hypoxic conditions. Providing oxygen during preservation might improve post-transplant outcomes, particularly for kidneys subjected to greater degrees of preservation injury. This study aimed to investigate whether supplemental oxygen during hypothermic machine perfusion (HMP) could improve the outcome of kidneys donated after circulatory death. METHODS: This randomised, double-blind, paired, phase 3 trial was done in 19 European transplant centres. Kidney pairs from donors aged 50 years or older, donated after circulatory death, were eligible if both kidneys were transplanted into two different recipients. One kidney from each donor was randomly assigned using permuted blocks to oxygenated hypothermic machine perfusion (HMPO(2)), the other to HMP without oxygenation. Perfusion was maintained from organ retrieval to implantation. The primary outcome was 12-month estimated glomerular filtration rate (eGFR) using the Chronic Kidney Disease Epidemiology Collaboration equation in pairs of donated kidneys in which both transplanted kidneys were functioning at the end of follow-up. Safety outcomes were reported for all transplanted kidneys. Intention-to-treat analyses were done. This trial is registered with the ISRCTN Registry, ISRCTN32967929, and is now closed. FINDINGS: Between March 15, 2015, and April 11, 2017, 197 kidney pairs were randomised with 106 pairs transplanted into eligible recipients. 23 kidney pairs were excluded from the primary analysis because of kidney failure or patient death. Mean eGFR at 12 months was 50·5 mL/min per 1·73 m(2) (SD 19·3) in the HMPO(2) group versus 46·7 mL/min per 1·73m(2) (17·1) in HMP (mean difference 3·7 mL/min per 1·73m(2), 95% CI -1·0 to 8·4; p=0·12). Fewer severe complications (Clavien-Dindo grade IIIb or more) were reported in the HMPO(2) group (46 of 417, 11%, 95% CI 8% to 14%) than in the HMP group (76 of 474, 16%, 13% to 20%; p=0·032). Graft failure was lower with HMPO(2) (three [3%] of 106) compared with HMP (11 [10%] of 106; hazard ratio 0·27, 95% CI 0·07 to 0·95; p=0·028). INTERPRETATION: HMPO(2) of kidneys donated after circulatory death is safe and reduces post-transplant complications (grade IIIb or more). The 12-month difference in eGFR between the HMPO(2) and HMP groups was not significant when both kidneys from the same donor were still functioning 1-year post-transplant, but potential beneficial effects of HMPO(2) were suggested by analysis of secondary outcomes.

Background: At the present four minimally invasive procedures namely retroperitoneoscopic (RPDN), laparoscopic (LPDN), hand-assisted retroperitoneoscopic (HARDN) and hand-assisted laparoscopic donor nephrectomy (HALDN) are used to perform donor nephrectomies. The current evidence based on retrospective studies and on pairwise only meta-analyses is inconclusive. Up to authors’ best knowledge there is no so far network meta-analysis to compare all the above-mentioned procedures. Therefore, a network meta-analysis was conducted to compare the feasibility, safety and reproducibility of the four donor nephrectomies procedures. Methods: Google Scholar, EMBASE, PubMed, and Cochrane library were used for a systematic literature search. Both updated pairwise and network meta-analyses were performed. Results: Compared to LPDN there was evidence of significantly more right kidneys retrieved with RPDN; nonsignificant differences demonstrated both with HALDN and HARDN compared to LPDN. There was evidence that the operative time was significantly shorter by 77 min in RPDN compared to LPDN; on the other hand, HARDN and HALDN did not demonstrate significant differences when compared to LPDN. Conclusions: The present study demonstrates that each approach can be applied safely in adequately selected patients. Moreover, retroperitoneoscopic is reliable, safe and easily reproducible alternative of LPDN for both left and right kidneys.

The prevailing coronavirus disease 2019 pandemic has challenged our lives in an unprecedented manner. The pandemic has had a significant impact on transplantation worldwide. The logistics of travel restrictions, stretching of available resources, unclear risk of infection in immunosuppressed transplant recipients, and evolving guidelines on testing and transplantation are some of the factors that have unfavourably influenced transplant activity. We must begin to build organisational flexibility in order to restart transplantation so that we can be mindful stewards of organ donation and sincere advocates for our patients. Building a culture of honesty and transparency (with patients, families, colleagues, societies, and authorities), keeping the channels of communication open, working in collaboration with others (at local, regional, national, and international levels), and not restarting without rethinking and appraising all elements of our practice, are the main underlying principles to increase the flexibility.

Background Despite technical refinements, early pancreas graft loss due to thrombosis continues to occur. Conventional coagulation tests (CCT) do not detect hypercoagulability and hence the hypercoagulable state due to diabetes is left untreated. Thromboelastogram (TEG) is an in-vitro diagnostic test which is used in liver transplantation, and in various intensive care settings to guide anticoagulation. TEG is better than CCT because it is dynamic and provides a global hemostatic profile including fibrinolysis. Aim To compare the outcomes between TEG and CCT (prothrombin time, activated partial thromboplastin time and international normalized ratio) directed anticoagulation in simultaneous pancreas and kidney (SPK) transplant recipients. Methods A single center retrospective analysis comparing the outcomes between TEG and CCT-directed anticoagulation in SPK recipients, who were matched for donor age and graft type (donors after brainstem death and donors after circulatory death). Anticoagulation consisted of intravenous (IV) heparin titrated up to a maximum of 500 IU/h based on CCT in conjunction with various clinical parameters or directed by TEG results. Graft loss due to thrombosis, anticoagulation related bleeding, radiological incidence of partial thrombi in the pancreas graft, thrombus resolution rate after anticoagulation dose escalation, length of the hospital stays and, 1-year pancreas and kidney graft survival between the two groups were compared. Results Seventeen patients who received TEG-directed anticoagulation were compared against 51 contemporaneous SPK recipients (ratio of 1: 3) who were anticoagulated based on CCT. No graft losses occurred in the TEG group, whereas 11 grafts (7 pancreases and 4 kidneys) were lost due to thrombosis in the CCT group (P = 0.06, Fisher's exact test). The overall incidence of anticoagulation related bleeding (hematoma/ gastrointestinal bleeding/ hematuria/ nose bleeding/ re-exploration for bleeding/ post-operative blood transfusion) was 17.65% in the TEG group and 45.10% in the CCT group (P = 0.05, Fisher's exact test). The incidence of radiologically confirmed partial thrombus in pancreas allograft was 41.18% in the TEG and 25.50% in the CCT group (P = 0.23, Fisher's exact test). All recipients with partial thrombi detected in computed tomography (CT) scan had an anticoagulation dose escalation. The thrombus resolution rates in subsequent scan were 85.71% and 63.64% in the TEG group vs the CCT group (P = 0.59, Fisher's exact test). The TEG group had reduced blood product usage {10 packed red blood cell (PRBC) and 2 fresh frozen plasma (FFP)} compared to the CCT group (71 PRBC/ 10 FFP/ 2 cryoprecipitate and 2 platelets). The proportion of patients requiring transfusion in the TEG group was 17.65% vs 39.25% in the CCT group (P = 0.14, Fisher's exact test). The median length of hospital stay was 18 days in the TEG group vs 31 days in the CCT group (P = 0.03, Mann Whitney test). The 1-year pancreas graft survival was 100% in the TEG group vs 82.35% in the CCT group (P = 0.07, log rank test) and, the 1-year kidney graft survival was 100% in the TEG group vs 92.15% in the CCT group (P = 0.23, log tank test). Conclusion TEG is a promising tool in guiding judicious use of anticoagulation with concomitant prevention of graft loss due to thrombosis, and reduces the length of hospital stay.

Background/aim We present a novel multi-faceted, internationally adaptable course curriculum blueprint, which provides holistic surgical education at the undergraduate level. Materials and methods The Integrated Generation 4 (iG4) course (Essential Skills in the Management of Surgical Cases - ESMSC Marathon course) curriculum consists of four essential learning components: core skills-based learning, case-based discussions, basic science workshops and soft-skills. These are all clustered in a specialty-led network architecture. Every cluster consists of modules from the four learning cores, while network nodes are modules that are mutually shared by more than one clusters. Results We produced a standardized blueprint of 50 modules based on the 4 learning cores, covering 9 surgical specialties. This resulted in a curriculum map where every module is described using 3 parameters: χ axis (skills component), y axis (knowledge component), z axis (specialty component). Conclusion iG4 proof of concept sets the ground for a novel, reproducible and standardised effort to produce a portfolio of undergraduate surgical skills serving the vision of holistic surgical education.

Studies have been carried out to investigate the effect of a prolonged cold ischaemia time (CIT) on the outcomes of living donor kidney transplantation (LDKT). There is no clear consensus in the literature about the effects of CIT on LDKT outcomes, and therefore, we performed a systematic review and meta-analysis to provide evidence on this subject. Searches were performed in five databases up to 12 July 2021. Articles comparing different CIT in LDKT describing delayed graft function (DGF), graft and patient survival, and acute rejection were considered for inclusion. This study is registered with PROSPERO, CRD42019131438. In total, 1452 articles were found, of which eight were finally eligible, including a total of 164,179 patients. Meta-analyses showed significantly lower incidence of DGF (odds ratio (OR) = 0.61, p < 0.01), and significantly higher 1-year graft survival (OR = 0.72, p < 0.001) and 5-year graft survival (OR = 0.88, p = 0.04), for CIT of less than 4 h. Our results underline the need to keep CIT as short as possible in LDKT (ideally < 4 h), as a shorter CIT in LDKT is associated with a statistically significant lower incidence of DGF and higher graft survival compared to a prolonged CIT. However, clinical impact seems limited, and therefore, in LDKT programmes in which the CIT might be prolonged, such as kidney exchange programmes, the benefits outweigh the risks. To minimize these risks, it is worth considering including CIT in kidney allocation algorithms and in general take precautions to protect high risk donor/recipient combinations.

The organ shortage and the increasing demand for organs are universal, worldwide challenges. Health literacy is a powerful tool that can help to increase awareness about organ donation and transplantation on a large scale and to encourage and sustain support for organ donation. The unique perspectives, experiences, and expectations of medical students, renal patients, and hospital administrative staff across the UK, Netherlands, and Spain on the topic of health literacy (HL) campaigns regarding deceased organ donation (DOD) were recorded in a cross-cultural, qualitative study. Focus group discussions enabled participants to express their views on existing HL campaigns and to propose novel pathways for future campaigns.

Background and Aims: Recipient demographics affect outcomes after kidney transplantation. The aim of this study was to assess, for kidneys retrieved from living donors, the effect of recipient sex, ethnicity, and body mass index (BMI) on delayed graft function (DGF) and one-year graft function, incidence of acute rejection (AR), and recipient and graft survivals. Methods: A systematic review and meta-analysis was performed. EMBASE and MEDLINE databases were searched using algorithms through Ovid. Web of Science collection, BIOSIS, CABI, Korean Journal database, Russian Science Citation Index, and SciELO were searched through Web of Science. Cochrane database was also searched. Risk of bias was assessed using the NHBLI tools. Data analysis was performed using Revman 5.4. Mean difference (MD) and risk ratio (RR) were used in analysis. Results: A total of 5129 studies were identified; 24 studies met the inclusion criteria and were analysed. Female recipients were found to have a significantly lower serum creatinine 1-year-post renal transplantation (MD: −0.24 mg/dL 95%CI: −0.18 to −0.29 p < 0.01) compared to male recipients. No significant difference in survival between male and female recipients nor between Caucasians and Africans was observed (p = 0.08). However, Caucasian recipients had a higher 1-year graft survival compared to African recipients (95% CI 0.52−0.98) with also a lower incidence of DGF (RR = 0.63 p < 0.01) and AR (RR = 0.55 p < 0.01). Recipient obesity (BMI > 30) was found to have no effect on 1-year recipient (p = 0.28) and graft survival (p = 0.93) compared to non-obese recipients although non-obese recipients had a lower rate of DGF (RR = 0.65 p < 0.01) and AR (RR = 0.81 p < 0.01) compared to obese recipients. Conclusions: Gender mismatch between male recipients and female donors has negative impact on graft survival. African ethnicity and obesity do not to influence recipient and graft survival but negatively affect DGF and AR rates.

OBJECTIVE To assess the impact of CIT on living donor kidney transplantation (LDKT) outcomes in the UKLKSS versus outside the scheme. BACKGROUND LDKT provides the best treatment option for end-stage kidney disease patients. end-stage kidney disease patients with an incompatible living donor still have an opportunity to be transplanted through Kidney Exchange Programmes (KEP). In KEPs where kidneys travel rather than donors, cold ischaemia time (CIT) can be prolonged. METHODS Data from all UK adult LDKT between 2007 and 2018 were analysed. RESULTS 9969 LDKT were performed during this period, of which 1396 (14%) were transplanted through the UKLKSS, which we refer to as KEP. Median CIT was significantly different for KEP versus non-KEP (339 versus 182 minutes, P < 0.001). KEP LDKT had a higher incidence of delayed graft function (DGF) (2.91% versus 5.73%, P < 0.0001), lower 1-year (estimated Glomerular Filtration Rate (eGFR) 57.90 versus 55.25 ml/min, P = 0.04) and 5-year graft function (eGFR 55.62 versus 53.09 ml/min, P = 0.01) compared to the non-KEP group, but 1- and 5-year graft survival were similar. Within KEP, a prolonged CIT was associated with more DGF (3.47% versus 1.95%, P = 0.03), and lower graft function at 1 and 5-years (eGFR = 55 vs 50 ml/min, P = 0.02), but had no impact on graft survival. CONCLUSION Whilst CIT was longer in KEP, associated with more DGF and lower graft function, excellent 5-year graft survival similar to non-KEP was found.

There are conflicting data about the role of transplant nephrectomy and immunosuppression withdrawal on the development of allosensitization and the impact on re-transplantation. We divided 109 first graft recipients into two groups according to whether they underwent nephrectomy (NX+, n = 61) or their graft was left in situ (NX-, n = 48). Sera were assessed for HLA-A/B/Cw/DR/DQ antibodies at the time of NX/transplant failure and after 3, 6, 12, 24 months. The NX+ group showed a higher rate of donor specific antibody (DSA) and non-DSA human leukocyte antigen (HLA) antibody production at all the time points. Multivariable analysis showed that nephrectomy was a strong, independent risk factor for the development of DSAs after 12 and 24 months (P = 0.005 and 0.008). In the NX- group, low tacrolimus levels correlated with DSA formation (AUC 0.817, P = 0.002; best cut-off level 2.9 ng/ml). Analysis with a standardized pool of UK donors showed a more difficult grade of HLA matchability following nephrectomy compared with the NX- group. Nephrectomy is followed by the long-term production of DSA and non-DSA HLA antibodies and negatively impacts on the chances of finding a HLA-compatible kidney. Tacrolimus levels ≥3 ng/ml are protective against the development of allosensitization and could facilitate re-transplantation in the NX- group.

Importance Continuous hypothermic machine perfusion during organ preservation has a beneficial effect on graft function and survival in kidney transplant when compared with static cold storage (SCS). Objective To compare the effect of short-term oxygenated hypothermic machine perfusion preservation (end-HMPo2) after SCS vs SCS alone on 1-year graft survival in expanded criteria donor kidneys from donors who are brain dead. Design, Setting, and Participants In a prospective, randomized, multicenter trial, kidneys from expanded criteria donors were randomized to either SCS alone or SCS followed by end-HMPo2 prior to implantation with a minimum machine perfusion time of 120 minutes. Kidneys were randomized between January 2015 and May 2018, and analysis began May 2019. Analysis was intention to treat. Interventions On randomization and before implantation, deceased donor kidneys were either kept on SCS or placed on HMPo2. Main Outcome and Measures Primary end point was 1-year graft survival, with delayed graft function, primary nonfunction, acute rejection, estimated glomerular filtration rate, and patient survival as secondary end points. Results Centers in 5 European countries randomized 305 kidneys (median [range] donor age, 64 [50-84] years), of which 262 kidneys (127 [48.5%] in the end-HMPo2 group vs 135 [51.5%] in the SCS group) were successfully transplanted. Median (range) cold ischemia time was 13.2 (5.1-28.7) hours in the end-HMPo2 group and 12.9 (4-29.2) hours in the SCS group; median (range) duration in the end-HMPo2 group was 4.7 (0.8-17.1) hours. One-year graft survival was 92.1% (n = 117) in the end-HMPo2 group vs 93.3% (n = 126) in the SCS group (95% CI, −7.5 to 5.1; P = .71). The secondary end point analysis showed no significant between-group differences for delayed graft function, primary nonfunction, estimated glomerular filtration rate, and acute rejection. Conclusions and Relevance Reconditioning of expanded criteria donor kidneys from donors who are brain dead using end-HMPo2 after SCS does not improve graft survival or function compared with SCS alone. This study is underpowered owing to the high overall graft survival rate, limiting interpretation. Trial Registration isrctn.org Identifier: ISRCTN63852508

Enhanced recovery after surgery (ERAS) initially started in the early 2000s as a series of protocols to improve the perioperative care of surgical patients. They aimed to increase patient satisfaction while reducing postoperative complications and postoperative length of stay. Despite these protocols being widely adopted in many fields of surgery, they are yet to be adopted in pancreatic transplantation: a high-risk surgery with often prolonged length of postoperative stay and high rate of complications. We have analysed the literature in pancreatic and transplantation surgery to identify the necessary preoperative, intra-operative and postoperative components of an ERAS pathway in pancreas transplantation.

Introduction There are limited data pertaining to comparative outcomes of remaining on dialysis versus kidney transplantation as the threat of coronavirus disease 2019 (COVID-19) remains. In this study we delineate the differential risks involved using serologic methods to help define exposure rates. Methods From a cohort of 1433 patients with end-stage kidney disease (ESKD), we analyzed COVID-19 infection rates and outcomes in 299 waitlist patients compared with 237 transplant recipients within their first year post-transplant. Patients were followed over a 68-day period from the time our transplant program closed due to COVID-19. Results The overall mortality rates in waitlist and transplant populations were equivalent (P = 0.69). However, COVID-19 infection was more commonly diagnosed in the waitlist patients (P = 0.001), who were more likely to be tested by reverse transcriptase polymerase chain reaction (P = 0.0004). Once infection was confirmed, mortality risk was higher in the transplant patients (P = 0.015). The seroprevalence in dialysis and transplant patients with undetected infection was 18.3% and 4.6%, respectively (P = 0.0001). After adjusting for potential screening bias, the relative risk of death after a diagnosis of COVID-19 remained higher in transplant recipients (hazard ratio = 3.36 [95% confidence interval = 1.19–9.50], P = 0.022). Conclusions Although COVID-19 infection was more common in the waitlist patients, a higher COVID-19‒associated mortality rate was seen in the transplant recipients, resulting in comparable overall mortality rates.

This meta-analysis aims to compare enhanced recovery after surgery (ERAS) vs. standard perioperative practice in the management of living kidney donors. Primary endpoints included mortality, complications, length of stay (LOS) and quality of life after living donor nephrectomy. Medline, Embase, Scopus, Cochrane and Web of Science databases were searched. In total, 3029 records were identified. We then screened 114 full texts. Finally, 11 studies were included in the systematic review corresponding to 813 living donors. Of these, four randomized controlled trials were included in the meta-analysis. ERAS resulted in shorter LOS (95CI: −1.144, −0.078, I2 = 87.622%) and lower incidence of post-operative complications (95CI: 0.158, 0.582, I2 = 0%). This referred to Clavien–Dindo I-II complications (95CI: 0.158, 0.582, I2 = 0%). There was no difference in Clavien–Dindo III-V complications (95CI: 0.061,16.173, I2 = 0%). ERAS donors consumed decreased amounts of narcotics during their hospital stay (95CI: −27.694, −8.605, I2 = 0%). They had less bodily pain (95CI:6.735, 17.07, I2 = 0%) and improved emotional status (95CI: 6.593,13.319, I2 = 75.682%) one month postoperatively. ERAS protocols incorporating multimodal pain control interventions resulted in a mean reduction of 1 day in donors’ LOS (95CI: −1.374, −0.763, I2 = 0%). Our results suggest that ERAS protocols result in reduced perioperative morbidity, shorter length of hospital stay and improved quality of life after living donor nephrectomy.

Making informed decisions such as organ donation requires access to accurate, readily available and reliable information. One of the most easily accessible resources are the official national websites of countries around the topic of Deceased organ Donation (DOD). The content of the official organ donation websites in the UK (NHSBT), the Netherlands (ONT) and Spain (NTS) were analysed. This is a step towards finding the parameters of a health literacy agenda on organ donation and transplantation. Cross-comparative content analysis was employed and subsequently thematic analysis was used to locate themes and sub-themes in the sections of these websites and coverage of themes was assessed. The analysis was performed using Atlas.ti software in 2014-2016. The information provided in these websites were categorised in five themes consisting of Theme 1: Personal Values for Organ Donation, Theme 2: Facts on the Organ Donation Process, Theme 3: Registration Options, Theme 4: Communicating with Family Members and Theme 5: Promotional resources. Within themes 2 and 3, further sub themes were identified to explore the topic more fully. The information in the websites provides an overview of the main areas of organ donation in which the public is informed in different countries and highlights that changes need to be implemented in an individual, community and population level.

PURPOSE Ensuring competence for surgical trainees requires holistic assessment of the qualities and competencies necessary to practice safely and effectively. To determine the next steps toward achieving this aim, the authors conducted a systematic review to summarize and appraise the available evidence related to any assessment approach to postgraduate surgical training and to identify the dominant themes for assessment approaches across different specialties or countries. METHOD Medline and Embase were searched on January 10, 2019, without language or time restrictions. Any peer-reviewed study that described an assessment framework (in practice or novel) throughout postgraduate surgical training globally was included. An iterative review and thematic analysis were performed on full-text articles to determine assessment themes. Studies were then grouped by assessment themes. A tailored quality assessment of the studies included in the final analysis was conducted. Assessment themes and validity were compared across surgical specialties and countries. RESULTS From an initial 7,059 articles, 91 studies (evaluating 6,563 surgical trainees) were included in the final analysis. Ten defined assessment themes were extracted. Ten studies (11.0%) were deemed low risk of bias based on the quality assessment tool used and thus were determined to be high quality. Minor differences in assessment themes were observed between specialties and countries. Assessment themes neglected by individual surgical specialties and assessment themes that need validated assessment tools were identified. CONCLUSIONS This review highlights the low quality of evidence and fragmented efforts to develop and optimize surgical assessments. The minor differences observed demonstrate a common approach, globally and across specialties, related to surgical assessments. A paradigm shift in assessment approaches, which will require national and international collaboration, is required to optimize design and validation so that a comprehensive assessment of surgical competence can be implemented.

Educating and equipping students and trainees into clinicians capable of meeting healthcare demands and service provision needs is essential. Unprecedented events like COVID-19 pandemic, highlight urgent need for reformation of training to ensure high quality education is maintained. To this end, we describe an innovative and globally adaptable blueprint for establishing a surgical curriculum, aiming to optimize preparation of future surgeons.We used a structured protocol to synthesize evidence from previous systematic reviews focused on surgical education alongside a series of focused original educational studies. This approach allowed incorporation of prospectively applied novel ideas into the existing landscape of published evidence. All material used for this proof of concept derives from the outputs of a dedicated research network for surgical education (eMERG).We propose the foundation blueprint framework called "Omnigon iG4" as a globally applicable model. It allows adaptation to individual local educational environments for designing, appraising and/or refining surgical curricula. We also describe the "Omnigon iG4 Hexagon Pragmatic Model," a novel perspective model which assesses the performance of our blueprint in a multi-layer fashion. This "Hexagon" model is the first to introduce pragmatic outcomes in curricula performance assessment.This proof of concept, "Omnigon iG4," proposes an adaptable version of a curriculum blueprint. The framework allows educators to establish a surgical curriculum with the ability to map out competencies, permitting full control over their intended learning outcomes. This can form the basis for developing globally adaptable multifaceted Simulation-Based learning (SBL) courses or even surgical curricula for undergraduates.

A case of transfusion-dependent anemia in a simultaneous pancreas and kidney (SPK) transplant recipient that masqueraded as gastrointestinal bleeding (GIB) is described. The anemia was attributed to bleeding from the donor duodenal cuff based on balloon enteroscopy findings. The patient underwent multiple contrast-enhanced computed tomography scans and multiple endoscopies with confounding features until, eventually, the diagnosis was established. We discuss the diagnostic difficulties and the therapeutic dilemma, along with the pitfalls in ascertaining the final diagnosis.

ObjectivesFaced with a costly and demanding learning curve of surgical skills acquisition, the growing necessity for improved surgical curricula has now become irrefutable. We took this opportunity to formulate a teaching framework with the capacity to provide holistic surgical education at the undergraduate level.SettingData collection was conducted in all the relevant healthcare centres the participants worked in. Where this was not possible, interviews were held in quiet public places.ParticipantsWe performed an in-depth retrospective evaluation of a proposed curriculum, through semi-structured interviews with 10 participants. A targeted sampling technique was employed in order to identify senior academics with specialist knowledge in surgical education. Recruitment was ceased on reaching data saturation after which thematic data analysis was performed using NVivo 11.ResultsThematic analysis yielded a total of 4 main themes and 29 daughter nodes. Majority of study participants agreed that the current landscape of basic surgical education is deficient at multiple levels. While simulation cannot replace surgical skills acquisition taking place in operating rooms, it can be catalytic in the transition of students to postgraduate training. Our study concluded that a standardised format of surgical teaching is essential, and that the Integrated Generation 4 (IG4) framework provides an excellent starting point.ConclusionsThrough expert opinion, IG4 has been validated for its capacity to effectively accommodate learning in a safer and more efficacious environment. Moreover, we support that through dissemination of IG4, we can instil a sense of motivation to students as well as develop robust data sets, which will be amenable to data analysis through the application of more sophisticated methodologies.

Pancreas transplantation is currently the treatment of choice for type 1 diabetes with end-stage renal failure. With the increasing number of patients being offered transplantation as an option, the dearth of suitable organs for transplantation has become evident. Pancreas allografts have the highest discard rate among abdominal transplants, and procurement related injuries contribute to a sizeable proportion of this. Clear understanding of the anatomical principles as well as insight into the pancreas vascular anatomy will allow the surgeon to make crucial decisions when faced with aberrant anatomy.
