Abstract
INTRODUCTION Iliac lymphadenectomy is performed to provide anastomotic access during the vascular implantation procedure in renal transplantation. Iliac lymph nodes (LNs) are often enlarged, but there are no standardised guidelines for the management of incidentally enlarged LNs during transplantation. We aimed to evaluate histological findings of LNs sent for examination at our unit. METHODS Patients were evaluated in two distinct date cycles. In the first cycle, lymphadenectomy and histological assessment were performed at the discretion of the transplanting surgeon. In the second cycle, all incidentally enlarged LNs were sent for histological assessment, regardless of size. RESULTS In the first cycle (n = 76), 11 patients (14.47%) had incidentally enlarged iliac LNs on lymphadenectomy and histology showed only reactive changes. In the second cycle (n = 165), eight patients (4.85%) had incidentally enlarged LNs on lymphadenectomy. One patient was found to have mature B cell chronic lymphocytic leukaemia. The patient was referred to haematology and a "watch and wait" approach was taken, with the patient still alive at last follow-up (511 days post-transplantation). DISCUSSION There are currently no published guidelines on the management of incidentally enlarged iliac LNs during transplantation. Current literature suggests that clinically significant lymphadenopathy needs to be investigated in all patients. Based on our centre's experience of a 5.26% (1 in 19) positive pathological LN sampling, we recommend that all incidental LNs with suspicious features and/or that are greater than 10mm in diameter should be considered for histological, microbiological and molecular assessment as appropriate.

Abstract
INTRODUCTION Enhanced recovery after surgery (ERAS) is well established in many specialties but has not been widely adopted in renal transplantation. The aim of this survey was to understand current national practices and sentiment concerning ERAS for renal transplant recipients in the UK. METHODOLOGY A national web-based survey was sent to consultant surgeons at all 23 UK adult renal transplant units. Completed questionnaires were collected between May and July 2020. Data were analysed according to individual responses and grouped according to the existence of formal ERAS pathways within units. RESULTS All transplant units were represented in this survey. Three units had a formal ERAS pathway for all recipients. Of the remaining units, 65.9% considered implementing an ERAS pathway in the near future. The most commonly perceived barrier to ERAS implementation was 'embedded culture within transplant units' (54.8% of respondents). A fifth of respondents insert surgical drains selectively and 11.7% routinely discontinue patient-controlled analgesia on postoperative day 1. Most respondents routinely remove urinary catheters on day 5 (70%) and ureteric stents 4-6 weeks post-transplantation (81.7%). Median length of stay for deceased donor kidney transplant recipients was lower in units with ERAS programmes (5-7 days versus 8-10 days, respectively). The main cited barriers for discharge were 'suboptimal fluid balance' and 'requirement of treatment for rejection'. CONCLUSIONS Despite slow uptake of ERAS in kidney transplantation, appetite appears to be increasing, particularly in the post-COVID-19 era. The current practice and opinions of transplant specialists highlighted in this survey may help to establish nationally agreed ERAS guidelines in this field.

Abstract
Abstract
Introduction
Liver resection can be associated with significant perioperative bleeding. Fibrin based haemostatic agents (FBHAs) are bioabsorbable topical haemostatic agents used to enhance haemostasis and reduce blood loss. We performed a systematic review and meta-analysis, comparing FBHAs with the standard of care and no topical application (SoC), and comparing FBHAs with non-fibrin-based haemostatic agents (NFHAs) to evaluate their efficacy in reducing blood loss and improving perioperative outcomes.
Method
The Cochrane Hepato-Biliary Specialised Register was searched to identify (quasi-) RCTs to include in our meta-analysis. Two authors independently reviewed each study. Primary outcomes were haemostatic efficacy (defined as haemostasis within 4 or 5 minutes post application), adverse events and perioperative mortality (within 30-days of surgery). Statistical analyses were performed using the random effects model and results expressed as odds ratio (OR) with 95% confidence intervals.
Result
Twenty-seven RCTs (3736 participants) were included in our analysis. FBHAs were found to have superior haemostatic efficacy compared to NFHAs (OR 4.03; 1.73–9.36, p=0.001), and were superior to SoC (OR 13.59; 4.06–45.47, p<0.0001). Incidence of adverse events and perioperative mortality was no different when comparing FBHAs with SoC or NFHAs. No differences were detected when testing for post-operative bile leakage, intra-abdominal collections, volume of abdominal drain output, post-operative transfusion requirements, reoperation rates and length of stay (all p>0.05).
Conclusion
FBHAs appear superior to SoC and NFHAs in achieving haemostasis within 4–5 minutes post-application, however this does not translate into improved post-operative outcomes. FBHAs are not justified for routine use based on the available evidence.

Abstract
Abstract
Introduction
Dextran 40 (D40) is a synthetic colloid with anticoagulant properties, which is commonly used instead of heparin following pancreas transplantation, however there is a lack of evidence over which is more effective. Graft thrombosis and pancreatitis, which may be mediated through micro or macrothrombosis within the graft, remain significant complications following pancreas transplantation. We hypothesised that D40 reduces inflammation through its antithrombotic pro-microcirculatory effects. We aimed to evaluate D40 compared to a heparin-based protocol by comparing post-operative complications and post-transplant levels of inflammation.
Method
Data were collected retrospectively for pancreas transplant patients between December 2009 and August 2018 – 26 patients had been treated with the pre-Dextran protocol and 37 had received D40. Post-operative complications and inflammatory markers (WCC, CRP and amylase) on post-operative days 1, 2, 3 and 7 were compared between the two groups. Potential confounders were also recorded.
Result
Patients in the D40 group had similar thrombosis rates but were less likely to have had substantial post-operative bleeding compared to the heparin-based protocol. The group who received D40 had significantly lower CRP and WCC on days 2, 3 and 7. The differences on days 3 and 7 remained when the results were adjusted for the significant confounders - cold ischaemic time and donor age.
Conclusion
D40 appears to be as effective as IV heparin at preventing graft thrombosis following pancreas transplant, and to confer a reduced risk of bleeding. It may also reduce post-operative inflammatory processes, leading to reduced graft pancreatitis.
Take-home message
Using Dextran 40 as an anticoagulant after pancreas transplantation is as effective as IV heparin at preventing graft thromboses and has a reduced risk of bleeding.

Abstract
Abstract
Introduction
Biliary leaks and anastomotic strictures are common early biliary complications (EBC) following liver transplantation. However, their impact on outcomes remains controversial and poorly described.
Method
The NHS registry on adult liver transplantation between 2006 and 2017 was retrospectively reviewed (n=8304). Multiple imputations were performed to account for missing data. Adjusted regression models were used to assess predictors of EBC, and their impact on outcomes. 35 potential variables were included, and backwards stepwise selection enabled unbiased selection of variables for inclusion in final models.
Result
EBC occurred in 9.6% of patients. Adjusted cox regression revealed that EBCs have a significant and independent impact on graft survival (Leak HR=1.325; P=0.021, Stricture HR=1.514; P=0.002, Leak plus stricture HR=1.533; P=0.034) and patient survival (Leak HR=1.218; P=0.131, Stricture HR=1.578; P<0.001, Leak plus stricture HR=1.507; P=0.044). Patients with EBC had longer median hospital stay (23 versus 15 days; P<0.001) and increased chance for readmission within the first year (56% versus 32%; P<0.001). On adjusted logistic regression the following were identified as independent risk factors for development of EBC: donation following circulatory death (OR=1.280; P=0.009), accessory hepatic artery (OR=1.324; P=0.005), vascular anastomosis time in minutes (OR=1.005; P=0.032) and ethnicity ‘other’ (OR=1.838; P=0.011).
Conclusion
EBCs prolong hospital stay, increase readmission rates and are independent risk factors for diminished graft survival and increased mortality in liver transplantation. We have identified factors that increase the likelihood of EBC occurrence; further research into interventions to prevent EBCs in these at-risk groups is vital to improve liver transplantation outcomes.
Take-home message
Using a large registry database we have shown that early anastomotic biliary complications are independent risk factors for decreased graft survival and increased mortality after liver transplantation. Research into interventions to prevent biliary complications in high risk groups are essential to improve liver transplant outcomes.

Abstract
Background Biliary leaks and anastomotic strictures are common early anastomotic biliary complications (EABCs) following liver transplantation. However, there are no large multicentre studies investigating their clinical impact or risk factors. This study aimed to define the incidence, risk factors and impact of EABC. Methods The NHS registry on adult liver transplantation between 2006 and 2017 was reviewed retrospectively. Adjusted regression models were used to assess predictors of EABC, and their impact on outcomes. Results Analyses included 8304 liver transplant recipients. Patients with EABC (9·6 per cent) had prolonged hospitalization (23 versus 15 days; P < 0·001) and increased chance for readmission within the first year (56 versus 32 per cent; P < 0·001). Patients with EABC had decreased estimated 5-year graft survival of 75·1 versus 84·5 per cent in those without EABC, and decreased 5-year patient survival of 76·9 versus 83·3 per cent; both P < 0.001. Adjusted Cox regression revealed that EABCs have a significant and independent impact on graft survival (leak hazard ratio (HR) 1·344, P = 0·015; stricture HR 1·513, P = 0·002; leak plus stricture HR 1·526, P = 0·036) and patient survival (leak HR 1·215, P = 0·136, stricture HR 1·526, P = 0·001; leak plus stricture HR 1·509; P = 0·043). On adjusted logistic regression, risk factors for EABC included donation after circulatory death grafts, graft aberrant arterial anatomy, biliary anastomosis type, vascular anastomosis time and recipient model of end-stage liver disease. Conclusion EABCs prolong hospital stay, increase readmission rates and are independent risk factors for graft loss and increased mortality. This study has identified factors that increase the likelihood of EABC occurrence; research into interventions to prevent EABCs in these at-risk groups is vital to improve liver transplantation outcomes.

Abstract
BACKGROUND Theoretical advantages of robotic surgery compared to conventional laparoscopic surgery include improved instrument dexterity, 3D visualization, and better ergonomics. This systematic review and meta-analysis aimed to determine advantages of robotic surgery over laparoscopic surgery in patients undergoing liver resections. METHOD A systematic literature search was conducted for studies comparing robotic assisted or totally laparoscopic liver resection. Meta-analysis of intraoperative (operative time, blood loss, transfusion rate, conversion rate), oncological (R0 resection rates), and postoperative (bile leak, surgical site infection, pulmonary complications, 30-day and 90-day mortality, length of stay, 90-day readmission and reoperation rates) outcomes was performed using a random effects model. RESULT Twenty-six non-randomized studies including 2630 patients (950 robotic and 1680 laparoscopic) were included, of which 20% had major robotic liver resection and 14% had major laparoscopic liver resection. Intraoperatively, robotic liver resection was associated with significantly less blood loss (mean: 286 vs 301 mL, p < 0.001) but longer operating time (mean: 281 vs 221 min, p < 0.001). There were no significant differences in conversion rates or transfusion rates between robotic liver resection and laparoscopic liver resection. Postoperatively, there were no significant differences in overall complications, bile leaks, and length of hospital stay between robotic liver resection and laparoscopic liver resection. However, robotic liver resection was associated with significantly lower readmission rates than laparoscopic liver resection (odds ratio: 0.43, p = 0.005). CONCLUSION Robotic liver resection appears to offer some advantages compared to conventional laparoscopic surgery, although both techniques appear equivalent. Importantly, the quality of evidence is generally limited to cohort studies and a high-quality randomized trial comparing both techniques is needed.

Abstract
BACKGROUND Surgical resection remains the only curative treatment for pancreatic ductal adenocarcinoma (PDAC). The prognostic value of resection margin status following pancreatoduodenectomy (PD) remains controversial. Standardised pathological assessment increases positive margins but limited data is available on the significance of involved margins. We investigated the impact of resection margin status in PDAC on patient outcome. METHOD We identified all patients with PD for PDAC at one pancreatic cancer centre between August 2008 and December 2014. Demographic, operative, adjuvant therapeutic and survival data was obtained. Pathology data including resection margin status of specific anatomic margins was collected and analysed. RESULTS 107 patients were included, all pathologically staged as T3 with 102 N1. 87.9% of patients were R1 of which 53.3% showed direct extension to the resection margin. Median survival for R0 patients versus R1<1 mm and R1 = 0 mm was 28.4 versus 15.4 and 25.1 versus 13.4 months. R1 = 0 mm status remained a predictor of poor outcome on multivariate analysis. Evaluation of individual margins (R1<1 mm) showed the SMV and SMA margins were associated with poorer overall survival. Multiple involved margins impacted negatively on outcome. SMA margin patient outcome with R1 = 1-1.9 mm was similar to R1=>2 mm. CONCLUSION Using an R1 definition of <1 mm and standardised pathology we demonstrate that R1 rates in PDAC can approach 90%. R1 = 0 mm remained an independent prognostic factor for overall survival. Using R1<1 mm we have shown that involvement of medial margins and multiple margins has significant negative impact on overall survival. We conclude that not all margin positivity has the same prognostic significance.

Abstract
Background Secondary resection of initially unresectable colorectal cancer liver metastases (CRLM) can prolong survival. The added value of selective internal radiotherapy (SIRT) to downsize lesions for resection is not known. This study evaluated the change in technical resectability of CRLM with the addition of SIRT to FOLFOX‐based chemotherapy. Methods Baseline and follow‐up hepatic imaging of patients who received modified FOLFOX (mFOLFOX6: fluorouracil, leucovorin, oxaliplatin) chemotherapy with or without bevacizumab (control arm) versus mFOLFOX6 (with or without bevacizumab) plus SIRT using yttrium‐90 resin microspheres (SIRT arm) in the phase III SIRFLOX trial were reviewed by three or five (of 14) expert hepatopancreatobiliary surgeons for resectability. Reviewers were blinded to one another, treatment assignment, extrahepatic disease status, and information on clinical and scanning time points. Technical resectability was defined as at least 60 per cent of reviewers (3 of 5, or 2 of 3) assessing a patient's liver metastases as surgically removable. Results Some 472 patients were evaluable (SIRT, 244; control, 228). There was no significant baseline difference in the proportion of technically resectable liver metastases between SIRT (29, 11·9 per cent) and control (25, 11·0 per cent) arms (P = 0·775). At follow‐up, significantly more patients in both arms were deemed technically resectable compared with baseline: 159 of 472 (33·7 per cent) versus 54 of 472 (11·4 per cent) respectively (P = 0·001). More patients were resectable in the SIRT than in the control arm: 93 of 244 (38·1 per cent) versus 66 of 228 (28·9 per cent) respectively (P < 0·001). Conclusion Adding SIRT to chemotherapy may improve the resectability of unresectable CRLM.

Abstract
AIMS Patients with chemotherapy-refractory colorectal cancer liver metastases have limited therapeutic options. Selective internal radiation therapy (SIRT) delivers yttrium 90 microspheres as a minimally invasive procedure. This prospective, single-arm, observational, service-evaluation study was part of National Health Service England Commissioning through Evaluation. METHODS Patients eligible for treatment had histologically confirmed carcinoma with liver-only/liver-dominant metastases with clinical progression during or following oxaliplatin-based and irinotecan-based chemotherapy. All patients received SIRT plus standard of care. The primary outcome was overall survival; secondary outcomes included safety, progression-free survival (PFS) and liver-specific PFS (LPFS). RESULTS Between December 2013 and March 2017, 399 patients were treated in 10 centres with a median follow-up of 14.3 months (95% confidence interval 9.2-19.4). The median overall survival was 7.6 months (95% confidence interval 6.9-8.3). The median PFS and LPFS were 3.0 months (95% confidence interval 2.8-3.1) and 3.7 months (95% confidence interval 3.2-4.3), respectively. During the follow-up period, 143 patients experienced an adverse event and 8% of the events were grade 3. CONCLUSION Survival estimates from this pragmatic study show clinical outcomes attainable in the National Health Service comparable with previously published data. This study shows the value of a registry-based commissioning model to aid national commissioning decisions for highly specialist cancer treatments.

Abstract
BACKGROUND Reduction of perioperative blood loss and intraoperative transfusion are two major factors associated with improving outcomes in liver surgery. There is currently no consensus as to the best technique to achieve this. METHODS An international Panel of Experts (EP), made up of hepatobiliary surgeons from well-known high-volume centres was assembled to share their experience with regard to the management of blood loss during liver resection surgery. The process included: a review of the current literature by the panel, a face-to-face meeting and an on-line survey completed by the EP prior to and following the face-to-face meeting, based on predetermined case scenarios. During the meeting the most frequently researched surgical techniques were appraised by the EP in terms of intraoperative blood loss. RESULTS All EP members agreed that high quality research on the subject was lacking. Following an agreed risk stratification algorithm, the EP concurred with the existing research that a haemostatic device should always be used along with any user preferred surgical instrumentation in both open and laparoscopic liver resection procedures, independently from stratification of bleeding risk. The combined use of Ultrasonic Dissector (UD) and saline-coupled bipolar sealing device (Aquamantys(®)) was the EP preferred technique for both open and laparoscopic surgery. CONCLUSIONS This EP propose the use of a bipolar sealer and UD for the best resection technique and essential equipment to minimise blood loss during liver surgery, stratified according to transfusion risk, in both open and laparoscopic liver resection.

Abstract
INTRODUCTION Retroperitoneal sarcoma is a surgically managed condition that can recur locally following macroscopically complete resection. Owing to the low incidence of the condition, advances in treatment are reported infrequently but complete compartmental resection and adjuvant or neoadjuvant radiotherapy are areas under investigation. Given the practical difficulty of randomised trials, observational data can highlight advantages from progressive treatment approaches. METHODS A retrospective database of consecutive retroperitoneal sarcoma resections performed at a single referral centre between March 1997 and March 2013 was interrogated. Histological, radiological and clinical data were collected. Univariate and multivariate analyses for disease free and overall survival were performed to establish independent predictors of disease recurrence and patient survival. RESULTS A total of 79 patients underwent 90 resections (63 primary). The mean five-year overall and disease free survival rates were 55.3% and 24.8% respectively. Higher patient age, high tumour grade, presence of extraretroperitoneal disease and invasive tumour phenotype were found to significantly predict survival following multivariate analysis. Half (50%) of the tumours displayed invasive behaviour on histopathology and 42% of locoregional recurrence was intraperitoneal. CONCLUSIONS Retroperitoneal sarcoma is commonly an infiltrative tumour and often recurs outside of the retroperitoneum. These features limit the therapeutic impact of interventions that focus on gaining local control such as complete compartmental resection and radiotherapy. It seems likely that future advances in the management of this cancer will involve new systemic agents to treat this frequently systemic disease.

Abstract
Outcomes after islet transplantation continue to improve but etiology of graft failure remains unclear. De novo donor-specific human leukocyte antigen (HLA) antibodies (DSA) posttransplant are increasingly recognized as a negative prognostic marker. Specific temporal associations between DSA and graft function remain undefined particularly in programs undertaking multiple sequential transplants. Impact of de novo DSA on graft function over 12 months following first islet transplant was determined prospectively in consecutive recipients taking tacrolimus/mycophenolate immunosuppression at a single center. Mixed-meal tolerance test was undertaken in parallel with HLA antibody assessment pretransplant and 1-3 months posttransplant. Sixteen participants received a total of 26 islet transplants. Five (19%) grafts were associated with de novo DSA. Five (31%) recipients were affected: three post-first transplant; two post-second transplant. DSA developed within 4 weeks of all sensitizing grafts and were associated with decreased stimulated C-peptide (median [interquartile range]) at 3 months posttransplant (DSA negative: 613(300-1090); DSA positive 106(34-235) pmol/L [p = 0.004]). De novo DSA directed against most recent islet transplant were absolutely associated with loss of graft function despite maintained immunosuppression at 12 months in the absence of a rescue nonsensitizing transplant. Alemtuzumab induction immunosuppression was associated with reduced incidence of de novo DSA formation (p = 0.03).

Abstract
Surgical injury to the pancreas is thought to occur commonly during procurement. The UK Transplant Registry was analyzed to determine the frequency of pancreatic injuries, identify factors associated with damage, and assess the impact of injuries on graft survival. Twelve hundred ninety-six pancreata were procured from donation after brain death donors, with 314 (19.5%) from donation after circulatory death donors. More than 50% of recovered pancreata had at least one injury, most commonly a short portal vein (21.5%). Liver donation, procurement team origin, hepatic artery (HA) arising from the superior mesenteric artery (SMA), and increasing donor BMI were associated with increased rates of pancreas damage on univariate analyses; on multivariate analysis only the presence of an HA from the SMA remained significant (p = 0.02). Six hundred forty solid organ pancreas transplants were performed; 238 had some form of damage. Overall, there was no difference in graft survival between damaged and undamaged organs (p = 0.28); however, graft loss was significantly more frequent in pancreata with arterial damage (p = 0.04) and in those with parenchymal damage (p = 0.05). Damage to the pancreas during organ recovery is more common than other organs, and meticulous surgical technique and awareness of damage risk factors are essential to reduce rates of procurement-related injuries.

Abstract
BACKGROUND Selective internal radiation therapy (SIRT) is a non-ablative technique for the treatment of liver primaries and metastases, with the intention of reducing tumour bulk. This study aimed to determine optimal patient selection, and elucidate its role as a downsizing modality. METHODS Data were collected retrospectively on patients who underwent SIRT between 2011 and 2014. The procedure was performed percutaneously by an expert radiologist. Response was analysed in two categories, based on radiological (CT/MRI according to Response Evaluation Criteria In Solid Tumours (RECIST)) and biological (α-fetoprotein, carcinoembryonic antigen, carbohydrate antigen 19-9, chromogranin A) parameters. RESULTS Forty-four patients were included. Liver metastases from colorectal cancer (22 patients) and hepatocellular carcinoma (HCC) (9) were the most common pathologies. Radiological response data were collected from 31 patients. A reduction in sum of diameters (SOD) was observed in patients with HCC (median -24.1 (95 per cent c.i. -43.4 to -3.8) per cent) and neuroendocrine tumours (-30.0 (-45.6 to -7.7) per cent), whereas a slight increase in SOD was seen in patients with colorectal cancer (4.9 (-10.6 to 55.3) per cent). Biological response was assessed in 17 patients, with a reduction in 12, a mixed response in two and no improvement in three. Six- and 12-month overall survival rates were 71 and 41 per cent respectively. There was no difference in overall survival between the RECIST response groups (median survival 375, 290 and 214 days for patients with a partial response, stable disease and progressive disease respectively; P = 0.130), or according to primary pathology (P = 0.063). Seven patients underwent liver resection with variable responses after SIRT. CONCLUSION SIRT may be used to downsize tumours and may be used as a bridge to surgery in patients with tumours deemed borderline for resection.

Abstract
INTRODUCTION Advanced (pT2/T3) incidental gallbladder cancer is often deemed unresectable after restaging. This study assesses the impact of the primary operation, tumour characteristics and timing of management on re-resection. METHODS The records of 60 consecutive referrals for incidental gallbladder cancer in a single tertiary centre from 2003 to 2011 were reviewed retrospectively. Decision on re-resection of incidental gallbladder cancer was based on delayed interval restaging at three months following cholecystectomy. Demographics, index cholecystectomy data, primary pathology, CA19-9 tumour marker levels at referral and time from cholecystectomy to referral as well as from referral to restaging were analysed. RESULTS Thirty-seven patients with pT2 and twelve patients with pT3 incidental gallbladder cancer were candidates for radical re-resection. Following interval restaging, 24 patients (49%) underwent radical resection and 25 (51%) were deemed inoperable. The inoperable group had significantly more patients with positive resection margins at cholecystectomy (p=0.002), significantly higher median CA19-9 levels at referral (p=0.018) and were referred significantly earlier (p=0.004) than the patients who had resectable tumours. On multivariate analysis, urgent referral (p=0.036) and incomplete cholecystectomy (p=0.048) were associated significantly with inoperable disease following restaging. CONCLUSIONS In patients with incidental, potentially resectable, pT2/T3 gallbladder cancer, inappropriate index cholecystectomy may have a significant impact on tumour dissemination. Early referral of breached tumours is not associated with resectability.

Abstract
BACKGROUND Laparoscopic distal pancreatectomy (LDP) is performed increasingly for pancreatic pathology in the body and tail of the pancreas. However, only few reports have compared its oncological efficacy with open distal pancreatectomy (ODP). We compared these two techniques in patients with pancreatic ductal adenocarcinoma. METHODS From a prospectively maintained database, all patients who underwent either LDP or ODP for adenocarcinoma in the body and tail of the pancreas between January 2008 and December 2011 were compared. Data were analysed using SPSS(®) v19 utilising standard tests. A p value <0.05 was considered significant. RESULTS Of 101 patients who underwent distal pancreatectomy, 22 had histologically confirmed adenocarcinoma (LDP n = 8, ODP n = 14). Both groups were well matched for age and the size of tumour (22 vs. 32 mm, p = 0.22). Intraoperative blood loss was 306 ml compared with 650 ml for ODP (p = 0.152). A longer operative time was noted for LDP (376 vs. 274 min, p < 0.05). Total length of stay was shorter for LDP compared with ODP (8 vs. 12 days, p = 0.05). The number of postoperative pancreatic fistulas were similar (LDP n = 2 vs. ODP n = 3, p = 0.5). Complete resection (R0) was achieved in 88 % of LDP (n = 7) compared with 86 % of ODP (n = 12). The median number of lymph nodes harvested was 16 for LDP versus 14 for ODP. Overall 3-year survival also was similar: LDP = 82 %, ODP = 74 % (p = 0.89). CONCLUSIONS From an oncological perspective, LDP is a viable procedure and its results are comparable to ODP for ductal adenocarcinomas arising in the body and tail of the pancreas.

Abstract
BACKGROUND Irreversible electroporation (IRE) is a novel procedure to combat pancreatic cancer, whereby high voltage pulses are delivered, resulting in cell death. This represents an ideal alternative to other thermal treatment modalities, as there is no overriding heat effect, therefore reducing the risk of injury to vessels and ducts. METHODS Multiple databases were searched to January 2014. Primary outcome measures were survival and associated morbidity. 41 articles were initially identified; of these 4 studies met the inclusion criteria, yielding 74 patients in total. RESULTS 94.5% of patients had locally advanced tumours, the remainder had metastatic disease. Treated tumour size ranged from 1 to 7 cm. IRE approach included open (70.3%), laparoscopic (2.7%) and percutaneous (27%; ultrasound-guided 30%, CT-guided 70%) Morbidity ranged from 0 to 33%; due to the high number of simultaneous procedures performed (resection/bypass) it was difficult to ascertain IRE-related complications. However no significant bleeding occurred when IRE-alone was performed. Survival statistics suggest a prognostic benefit. Reported survival included: 6 month survival of 40% (n = 5) and 70% (n = 14); PFS and OS 14 and 20 months respectively (n = 54). Results of most interest showed a significant survival benefit in matched IRE vs non-IRE groups (PFS 14 vs 6 mths; p = 0.01, OS 20 vs 11 mths; p = 0.03). CONCLUSION Initial evidence suggests IRE incurs a prognostic benefit with minimal morbidity. More high quality research is required to determine the role IRE may play in the multi-modal management of pancreatic cancers.

Abstract
INTRODUCTION We present a rare case in which both a double cardiac valve replacement was performed as well as a hepatic resection. PRESENTATION OF CASE We report the case of a 36 year old patient who presented with intra abdominal bleeding thought to have been caused by a liver haemangioma she also had severe autoimmune cardiac valve disease. She underwent a simultaneous right hepatectomy with cardiac valve replacement. DISCUSSION Management of this challenging case is discussed. CONCLUSION We advocate the possibility of performing combined operations where both valve replacement and hepatic resection is required.

Abstract
INTRODUCTION A variety of factors have been identified in the literature which influence survival following resection of colorectal liver metastases (CRLM). Much of this literature is historical, and its relevance to contemporary practice is not known. The aim of this study was to identify those factors which influence survival during the era of preoperative chemotherapy in patients undergoing resection of CRLM in a UK centre. METHODS All patients having liver resection for CRLM during an 11-year period up to 2011 were identified from a prospectively maintained database. Prognostic factors analysed included tumour size (≥5 or <5 cm), lymph node status of the primary tumour, margin positivity (R1; <1 mm), neo-adjuvant chemotherapy (for liver), tumour differentiation, number of liver metastases (≥4), preoperative carcinoembryonic antigen (CEA; ≥200 ng/ml) and whether metastases were synchronous (i.e. diagnosed within 12 months of colorectal resection) or metachronous to the primary tumour. Overall survival (OS) was compared using Kaplan-Meier plots and a log rank test for significance. Multivariate analysis was performed using a Cox regression model. Statistical analysis was performed in SPSS v19, and p < 0.05 was considered to be significant. RESULTS 432 patients underwent resection of CRLM during this period (67% male; mean age 64.5 years), and of these, 54 (13.5%) had re-resections. The overall 5-year survival in this series was 43% with an actuarial 10-year survival of 40%. A preoperative CEA ≥200 ng/ml was present in 10% of patients and was associated with a poorer 5-year OS (24 vs. 45%; p < 0.001). A positive resection margin <1 mm was present in 16% of patients, and this had a negative impact on 5-year OS (15 vs. 47%; p < 0.001). Tumour differentiation, number, biliary or vascular invasion, size, relationship to primary disease, nodal status of the primary disease or the use of neo-adjuvant chemotherapy had no impact on OS. Multivariate analysis identified only the presence of a positive resection margin (OR 1.75; p < 0.05) and a preoperative CEA ≥200 ng/ml (OR 1.88; p < 0.01) as independent predictors of poor OS. CONCLUSION Despite the wide variety of prognostic factors reported in the literature, this study was only able to identify a preoperative CEA ≥200 ng/ml and the presence of tumour within 1 mm of the resection margin as being of value in predicting survival. These variables are likely to identify patients who may benefit from intensive follow-up to enable early aggressive treatment of recurrent disease.

Abstract
INTRODUCTION Between 4% and 13% of patients with operable pancreatic malignancy are found unresectable at the time of surgery. Double bypass is a good option for fit patients but it is associated with high risk of postoperative complications. The aim of this study was to identify pre-operatively which patients undergoing double bypass are at high risk of complications and to assess their long-term outcome. METHODS Of the 576 patients undergoing pancreatic resections between 2006 and 2011, 50 patients who underwent a laparotomy for a planned pancreaticoduodenectomy had a double bypass procedure for inoperable disease. Demographic data, risk factors for postoperative complications and pre-operative anaesthetic assessment data including the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) and cardiopulmonary exercise testing (CPET) were collected. RESULTS Fifty patients (33 men and 17 women) were included in the study. The median patient age was 64 years (range: 39–79 years). The complication rate was 50% and the in-hospital mortality rate was 4%. The P-POSSUM physiology subscore and low anaerobic threshold at CPET were significantly associated with postoperative complications (p=0.005 and p=0.016 respectively) but they were unable to predict them. Overall long-term survival was significantly shorter in patients with postoperative complications (9 vs 18 months). Postoperative complications were independently associated with poorer long-term survival (p=0.003, odds ratio: 3.261). CONCLUSIONS P-POSSUM and CPET are associated with postoperative complications but the possibility of using them for risk prediction requires further research. However, postoperative complications following double bypass have a significant impact on long-term survival and this type of surgery should therefore only be performed in specialised centres.

Abstract
Abstract
Background
During the past decade the number of livers recovered and transplanted from donation after circulatory death (DCD) donors has increased significantly. As reported previously, injuries are more frequent during kidney procurement from DCD than from donation after brain death (DBD) donors. This aim of this study was to compare outcomes between DCD and DBD with respect to liver injuries.
Methods
Data on liver injuries in organs procured between 2000 and 2010 were obtained from the UK Transplant Registry.
Results
A total of 7146 livers were recovered from deceased donors during the study, 628 (8·8 per cent) from DCD donors. Injuries occurred in 1001 procedures (14·0 per cent). There were more arterial (1·6 versus 1·0 per cent), portal (0·5 versus 0·3 per cent) and caval (0·3 versus 0·2 per cent) injuries in the DBD group than in the DCD group, although none of these findings was statistically significant. Capsular injuries occurred more frequently in DCD than DBD (15·6 versus 11·4 per cent; P = 0·002). There was no significant difference between DCD and DBD groups in liver discard rates related to damage.
Conclusion
There were no differences in terms of vascular injuries between DCD and DBD livers, although capsular injuries occurred more frequently in DCD organs. Continuing the trend for increased frequency of DCD liver recovery, and ensuring that there is an adequately skilled surgical team available for procurement, is vital to improving the utilization of DCD livers.

Abstract
Abstract
Background
Postoperative complications are increased in patients with reduced cardiopulmonary reserve undergoing major surgery. Pancreatic leak is an important contributor to postoperative complications and death following pancreaticoduodenectomy. The aim of this study was to determine whether reduced cardiopulmonary reserve was a risk factor for pancreatic leak.
Methods
All patients who underwent pancreaticoduodenectomy between January 2006 and July 2010 were identified from a prospectively held database. Data analysis was restricted to those who underwent cardiopulmonary exercise testing during preoperative assessment. Pancreatic leak was defined as grade A, B or C according to the International Study Group on Pancreatic Fistula definition. An anaerobic threshold (AT) cut-off value of 10·1 ml per kg per min was used to identify patients with reduced cardiopulmonary reserve. Univariable and multivariable analyses were performed to identify other risk factors for pancreatic leak.
Results
Some 67 men and 57 women with a median age of 66 (range 37–82) years were identified. Low AT was significantly associated with pancreatic leak (45 versus 19·2 per cent in patients with greater cardiopulmonary reserve; P = 0·020), postoperative complications (70 versus 38·5 per cent; P = 0·013) and prolonged hospital stay (29·4 versus 17·5 days; P = 0·001). On multivariable analysis, an AT of 10·1 ml per kg per min or less was the only independent factor associated with pancreatic leak.
Conclusion
Low cardiopulmonary reserve was associated with pancreatic leak following pancreaticoduodenectomy. AT seems a useful tool for stratifying the risk of postoperative complications.

Abstract
During the last 10 years, kidneys recovered/transplanted from donors after circulatory death (DCD) have significantly increased. To optimize their use, there has been an urgent need to minimize both warm and cold ischemia, which often necessitates more rapid removal. To compare the rates of kidney injury during procurement from DCD and donors after brain death (DBD) organ donors. A total of 13 260 kidney procurements were performed in the United Kingdom over a 10-year period (2000-2010). Injuries occurred in 903 procedures (7.1%). Twelve thousand three hundred seventy-two (93.3%) kidneys were recovered from DBD donors and 888 (6.7%) from DCD donors. The rates of kidney injury were significantly higher when recovered from DCD donors (11.4% vs. 6.8%, p < 0.001). Capsular, ureteric and vascular injuries were all significantly more frequent (p = 0.002, p < 0.001 and p = 0.017, respectively). Discard because of injury was more common after DCD donation (p = 0.002). Multivariate analysis demonstrated procurement injuries were significantly associated with DCD donors (p = 0.035) and increased donor age (<0.001) and donor body mass index (BMI; 0.001), donor male gender (p = 0.001) and no liver donation (0.009). We conclude that procurement from DCD donors leads to higher rates of injury to the kidney and are more likely to be discarded.

Abstract
BACKGROUND Overall five year survival following pancreaticoduodenectomy for ductal adenocarcinoma is poor with typical reported rates in the literature of 8-27%. The aim of this study was to identify the histological variables best able to predict long-term survival in these patients. METHODS A prospective database of patients undergoing pancreaticoduodenectomy between April 2002 and June 2009 was analysed to identify patients with histologically proven pancreatic ductal adenocarcinoma. Patients with ampullary tumours, cholangiocarcinoma, duodenal adenocarcinoma and neuroendocrine tumours were excluded. The histology reports for these patients were reviewed. Uni-variate and multi-variate survival analysis was performed to identify variables useful in predicting long-term outcome. RESULTS 134 patients underwent pancreaticoduodenectomy for pancreatic ductal adenocarcinoma during this period. 5 year survival in this series was 18.6%. Uni-variate analysis identified nodal status and the metastatic to resected lymph node ratio as predictors of survival. Using multi-variate Cox Regression analysis a metastatic to lymph node ratio of >15% (p < 0.01) and the presence of perineural invasion (p < 0.05) were identified as independent predictors of patient survival. Metastatic to resected lymph node ratio is better able to stratify prognosis than nodal status alone with 5 year survival of those with N0 disease being 55.6% and 12.9% for N1 disease. However for those with <15% of resected nodes positive, 5 year survival was 21.7% and in those with >15% nodes positive it was 5.2% (p = 0.0017). CONCLUSION The metastatic to resected lymph node ratio can provide significant prognostic information in those patients with node positive disease after pancreaticoduodenectomy for pancreatic ductal adenocarcinoma.

Abstract
The NHS plan published by the Department of Health (DH) in 2000 recommended that patients should receive copies of all clinician-generated correspondence written about them. Concerns from many groups delayed widespread implementation of the policy and a committee set up under the NHS Modernisation Board recommended that further research was required in this area prior to rolling out the policy fully. Good practice guidelines on copying letters to patients were subsequently produced by the DH in 2001.

Abstract
Surgical resection for colorectal liver metastases may only be considered when an adequate functional residual volume can be preserved. Selective portal venous embolisation may be used to increase this volume, whilst chemotherapy and radiofrequency ablation (RFA) can be used to treat inoperable lesions. A 73-year-old man with liver metastasis proceeded to surgery, with the intention to perform a right hemi-hepatectomy. Unexpectedly at laparotomy, despite adequate pre-operative imaging, both the right and middle hepatic veins were involved. At that time extended right hemi-hepatectomy was contraindicated by insufficient residual volume and RFA was performed. Follow-up imaging revealed atrophy of the lesion. Significantly, there was also left lateral lobe hypertrophy sufficient to permit resection, which was performed without complication. Thrombosis of intra-hepatic portal veins is a recognised complication of RFA but here it appears to have been beneficial. The case highlights the need for regular review of unresectable hepatic disease by a liver surgeon and could suggest new modalities of portal embolisation.

Abstract
INTRODUCTION Retroperitoneal soft tissue sarcomas represent a relatively rare and complex therapeutic problem where surgery forms the mainstay of treatment and is technically demanding. In this study, we review a single UK centre's experience with the surgical management of retro-peritoneal soft tissue sarcoma. PATIENTS AND METHODS We present analysis of data on patients treated between 1997 and 2006, our first 75 patients. Data collected from the Access database, included patient demographics, staging modalities, peri-operative details, treatment, outcome, pathological diagnosis and subsequent complications. RESULTS A total of 75 patients (M:F, 44:31) underwent 115 resectional procedures as part of the management of retroperitoneal soft-tissue sarcoma. There were 12 major complications for the 115 procedures (morbidity of 8.69%). The 30-day operative mortality was zero and the 90-day mortality rate was 1.33% (1/75). Follow-up ranged from 16-131 months. The median disease-free survival was 69 months (range, 59-78 months). Recurrences developed in 46 patients; median time to overall recurrence was 13 months (range, 3-71 months). Of these 46, 22 developed localised recurrence, which was amenable to further resection. In the cohort of patients with recurrent disease, median survival in those who underwent surgery was 53 months (range, 30-76 months) and median survival in those who did not undergo surgery was 30 months (range, 18-41 months) and this difference was statistically significant (log rank, P = 0.01). CONCLUSIONS Extensive resectional surgery with minimal morbidity, devoid of mortality is feasible in the treatment of retroperitoneal sarcoma. Development of recurrent disease is a significant factor influencing survival; however, localised recurrences are amenable to surgery and this can lead to improved survival.

Abstract
INTRODUCTION To avoid the risk of complications of biliary drainage, a feasibility study was carried out to determine whether it might be possible to fast-track surgical treatment, with resection before biliary drainage, in jaundiced patients with proximal pancreatic/peri-ampullary malignancy. PATIENTS AND METHODS Over an 18-month period, based on their presenting bilirubin levels and other logistical factors, all jaundiced patients who might be suitable for fast-track management were identified. Data on complications and hospital stay were compared with those patients in whom a conventional pathway (with biliary drainage) was used during the same time period. Data were also compared with a group of patients from the preceding 6 months. RESULTS Nine patients were fast-tracked and 49 patients treated in the conventional pathway. Fast-track patients mean (SD) serum bilirubin level was 265 micromol/l (81.6) at the time of the operation compared to 43 micromol/l (51.3; P > or = 0.0001) in conventional patients. Mean (SD) of time from referral to operation, 14 days (9) versus 59 days (36.9), was significantly shorter in fast-track patients than conventional patients (P < or = 0.0001). Length of hospital stay mean (SD) at 17 (6) days versus 22 days (19.6; P = 0.2114), surgical complications and mortality in fast-track patients were similar to conventional patients. Prior to surgery, the 49 conventional patients underwent a total of 73 biliary drainage procedures resulting in seven major complications. Comparison with the group of patients from the previous 6 months indicated that the conventional group were not disadvantaged. CONCLUSIONS Fast-track management by resection without biliary drainage of selected patients with distal biliary strictures is safe and has the potential to reduce the waiting time to surgery, overall numbers of biliary drainage procedures and the complications thereof.

Abstract
BACKGROUND This study compared multislice computed tomography (MSCT) with endoscopic ultrasonography (EUS) in the diagnosis and staging of pancreatic and periampullary malignancy. METHODS Data were collected prospectively on patients having MSCT and EUS for suspected pancreatic and periampullary malignancy. RESULTS Eighty-four patients had MSCT and EUS, of whom 35 underwent operative assessment (29 resections). In assessing malignancy, there was no significant difference between MSCT and EUS, and agreement was good (82 per cent, kappa = 0.49); the sensitivity and specificity of MSCT were 97 and 87 per cent, compared with 95 and 52 per cent respectively for EUS (P = 0.264). For portal vein/superior mesenteric vein invasion, MSCT was superior (P = 0.017) and agreement was moderate (72 per cent, kappa = 0.42); the sensitivity and specificity were 88 and 92 per cent for MSCT, and 50 and 83 per cent for EUS. For resectability, there was no significant difference and agreement was good (78 per cent, kappa = 0.51). EUS had an impact on the management of 14 patients in whom MSCT suggested benign disease or equivocal resectability. CONCLUSION MSCT is the imaging method of choice for pancreatic and periampullary tumours. Routine EUS should be reserved for those with borderline resectability on MSCT.

Abstract
As demand for donor pancreases increases, attempts are being made to utilize even marginal grafts for transplantation. Injury during pancreas recovery can predispose to posttransplant complications and graft loss. Early recognition and correction can salvage these grafts. The authors report an instance of poor segmental perfusion of the pancreas graft that was salvaged by pancreas head resection and enteric drainage through a Roux-en-Y pancreatico-jejunostomy.

Abstract
BACKGROUND Liver transplantation is the treatment of choice for patients with end-stage liver disease (ESLD) and early hepatocellular carcinoma (HCC), Routine laparoscopy with intraoperative ultrasound was employed in an attempt to improve patient selection for transplantation. Our aim was to assess whether laparoscopy improved the patient selection with ESLD and HCC being considered for transplantation. METHODS We retrospectively reviewed the clinical notes and transplant database of all patients with ESLD complicated by HCC, being assessed for liver transplantation, from January 2000 to April 2005. RESULTS Twenty-five patients with ESLD and HCC underwent assessment for liver transplantation. Eight were deemed untransplantable on cross-sectional imaging alone. Sixteen patients underwent laparoscopy and intraoperative ultrasound. One patient had undergone a previous segmental hepatectomy and laparoscopy was not technically feasible. At laparoscopy, all 16 patients were found to be free from extrahepatic disease and major vascular involvement. All 16 patients were listed for transplantation. At transplantation, one patient was found to have extrahepatic disease; the procedure was abandoned. One patient was found to have lesser curvature lymphadenopathy, Two patients had major vascular involvement noted in the explanted liver. All these findings were missed on pretransplant imaging and at laparoscopy. CONCLUSIONS As an additional investigation, laparoscopy did not improve staging or alter the management of patients with HCC being assessed for liver transplantation. Since July 2005, we have ceased routine laparoscopic assessment of patients prior to listing. The decision use laparoscopy on patients is now being taken on a more selective basis.

Abstract
At some point in the natural course of colorectal cancer up to 50% of patients will develop metastasis to the liver. Historically only 20% of these patients would have to be deemed resectable, with an intent to cure, at the time of presentation. But with recent improvements in cross-sectional imaging, chemotherapeutic agents and advances in the techniques of surgical resection the emphasis of resection has now changed to 'who is not resectable' as opposed to 'who is resectable'. There are few contraindications to liver resection on the proviso that the patient is fit enough. As a result of this paradigm shift, 5 year survival rates are approaching 60%. Historically liver resection was perceived as a formidable operation but now liver resection for CRLM is safe and specialist centres are reporting mortality rates of less than 1%. This review briefly covers the standard techniques currently employed and some of the recent innovations being developed to improve resectability.

Abstract
Intraarterial cooling (IAC) of non-heart-beating donors (NHBD) for renal donation requires a cheap, low-viscosity solution. HTK contains a high hydrogen ion buffer level that theoretically should reduce the observable acidosis associated with ongoing anaerobic metabolism. A retrospective comparison of all retrieved NHBD kidneys as well as of viability on the Organ Recovery Systems Lifeporter machine perfusion circuit was performed with respect to the preservation solution HTK or Marshall's HOC. Forty-two NHBD kidneys (19 HTK and 23 HOC) were machine perfused between February 2004 and May 2005. Most of the HTK kidneys were obtained from uncontrolled donors (12 vs 5; Fisher exact test, P = .01). As a consequence, the glutathione-s-transferase viability assay (411 vs 292 IU/L, P = .12) and the lactate concentrations (2.33 vs 1.94 mmol/L, P = .13) were higher among the HTK cohort. There was evidence of greater buffering capacity in HTK, since the lactate:hydrogen ion ratios were consistently lower during the first 2 perfusion hours (1 hour P = .03, 2 hour P = .02). A linear regression analysis confirmed that this was related to the IAC solution (ANCOVA, P < .001). All controlled donor kidneys passed viability testing and were transplanted. In contrast, 83% (10/12) of the uncontrolled donor kidneys preserved with HTK passed the viability test and were transplanted, compared with only 20% (1/5) of the HOC-treated comparators (Fisher exact test, P = .03). It may be concluded that the postulated advantages of improved pH buffering with HTK appear to have clinical relevance.

Abstract
Non-heart-beating donor kidneys (NHBD) are being used to increase the donor pool due to the scarcity of cadaveric heart beating donors (HBD). We evaluated the long-term outcomes of renal transplantation using NHBD kidneys, comparing the first 100 NHBD kidneys transplanted at our facility to the next consecutive cadaveric HBD kidneys for graft survival, recipient survival, and quality of graft function. Recipient survival (P = .22) and graft survival (P = .19) at 6 years did not differ between recipients of NHBD (83%, 80%) and HBD (89%, 87%) kidneys. Quality of graft function using the mean glomular filtration rates were significantly lower in the NHBD group up to 3 months following discharge (41 +/- 2 vs 47 +/- 2, P = .007) but were then comparable up to 6 years following transplantation (43 +/- 5 vs 46 +/- 4, P = .55).

Abstract
Due to the organ shortage, many renal transplantation centers attempt to increase the donor pool by using non-heart-beating donors (NHBDs). These kidneys are generally regarded as "marginal" grafts. Many centers do not consider transplantation from an NHBD with a history of diabetes as it is a more suboptimal donor. We began our NHBD program in 1998 and have performed 5 renal transplants from diabetic NHBDs. Viability testing identified kidneys suitable for single or dual transplantation. Although kidneys from brain stem dead donors with diabetes have been used successfully, our data suggested that kidneys from diabetic NHBDs can also be used although we still need long-term results.

Abstract
Graft thrombosis is one of the most devastating complications of transplantation. In obtaining consent prior to transplant, it is useful to share potential risk factors with the recipient. In order to do this, we explored the impact of different risk factors that could contribute to this complication. Using multivariate analysis we found that neither multiple vessels nor vascular injury had a bearing on the risk of graft thrombosis but atheroma did (P < .02).
