Abstract
BACKGROUND Minimally invasive resection of the retroperitoneal duodenum is complicated because of its anatomical location, and the proximity of the ampulla of Vater and vascular structures. Benign or indolent pathology can add complexity to operative decision-making for these already challenging surgeries, and operations associated with lower morbidity may be considered. This study describes a novel robotic transmesenteric approach to duodenal sleeve resection for non-malignant lesions. METHODS A retrospective review was performed on a prospectively maintained institutional database between 2011 and 2021. The Da Vinci XI or SI platform (Intuitive Surgical, Sunnyvale, CA) was used in all cases. RESULTS Critical steps in robotic sleeve duodenectomy include the following: (1) techniques for avoiding damage to the ampulla; (2) Kocherization and reverse Kocherization; and (3) A transmesenteric approach for further mobilization of the duodenum. Nineteen patients were referred by experienced gastrointestinal endoscopists after endoscopic management was deemed unsuitable or their resections were incomplete. The histological diagnoses were either symptomatic benign or indolent duodenal pathology. All 19 patients underwent robotic duodenal sleeve resection during the study period. Lesions were located in the third to fourth parts of the duodenum. The median operative time was 216 min (IQR: 199-225), and the estimated intraoperative blood loss was 50 ml (IQR: 50.0-93.7). The 90 day readmission rate was 15.7% (3/19), and no 90-day mortality was observed. CONCLUSION This small case series of a transmesenteric approach for robotic sleeve duodenectomy demonstrates its feasibility and safety in this potentially challenging operation.

Abstract
Abstract
Objective
Long-term outcomes of patients with ruptured hepatocellular carcinoma (rHCC) remain scant. This study aimed to assess disease-free survival (DFS) and overall survival (OS) after surgical resection of rHCC compared to non-ruptured HCC (nrHCC).
Methods
Patients with rHCC and nrHCC were collected from 8 centers in Europe, Asia, and North America. Resected rHCC patients were matched 1:1 to patients undergoing surgery for nrHCC using propensity score and nearest-neighbor method (matching criteria: age, tumor size, cirrhosis, Child-Pugh score, Barcelona Clinic Liver Cancer stage, resection status, grade, and microvascular invasion). Survival rates were calculated using Kaplan-Meier method.
Results
A total of 2033 patients were included: 226 rHCC patients (172 operated: 68 with upfront surgery and 104 after embolization) and 1807 nrHCC patients. Median DFS and OS of rHCC patients (all treatments confounded) were 10 months (95% CI 7–13) and 22 months (95% CI 13–31). Prognostic factors for worse OS among rHCC patients were absence of preoperative arterial embolization (HR 2.3, 95% CI 1.2–4.6, p=0.016), cirrhosis Child B/C (HR 2.4, 95% CI 1.1–5.4, p=0.040), and R1/R2 margins (HR 2, 95% CI 1–5, p=0.049). Survivals were similar between Western and Eastern rHCC patients.
After propensity score matching, 106 rHCC patients and 106 nrHCC patients displayed similar characteristics. Patients with rHCC had shorter median DFS (12 months, 95% CI 7–17 vs. 22 months, 95% CI 12–32, p=0.011), but similar median OS compared to nrHCC patients (43 months, 95% CI 21–65 vs. 63 months, 95% CI 21–105, p=0.060).
Conclusion
In this large dataset including Eastern and Western patients, rHCC was associated with shorter DFS compared to nrHCC, while OS was similar.

Abstract
Abstract
Objective
Lymph node ratio (LNR, positive lymph nodes/collected lymph nodes during surgery) was identified as an important prognostic factor of survival in resected pancreatic cancer. Several nomograms based on LNR were recently proposed to predict survival after pancreatoduodenectomy (PD). The present study aimed to externally validate 3 published nomograms using an international cohort.
Methods
Consecutive patients with ductal adenocarcinoma of the pancreatic head who underwent PD without neoadjuvant treatment from 6 tertiary centers in Europe and the USA were retrospectively collected from 2000 to 2017. Patients with metastases at diagnosis, R2 resection, missing data regarding LNR, and who died within 90 postoperative days were excluded. The 3 selected nomograms were the updated Amsterdam nomogram (including LNR, adjuvant therapy, margin status, and tumor grade), the nomogram by Pu et al. (including LNR, age, tumor grade, and T stage) and the nomogram by Li et al. (including LNR, age, tumor location, grade, size, and TNM stage). Overall survivals (OS) were calculated using Kaplan-Meier method. For the validation, calibration (Hosmer-Lemeshow test), discrimination capacity (ROC curves for 3-year OS), and clinical utility (sensitivity and specificity at the value of Youden index) were assessed.
Results
After exclusion of 95 patients with metastases, R2 resection, and who died within 90 postoperative days, 1167 patients were included. Median OS of the entire cohort was 23 months (95% confidence interval: 21-24).
For the 3 nomograms, Kaplan-Meier curves showed significant diminution of OS with increasing scores (p < 0.01 for the 3 nomograms). All nomograms showed good calibration (non significant Hosmer-Lemeshow goodness-of-fit tests). For the updated Amsterdam nomogram, the area under the ROC curve (AUROC) for 3-year OS was 0.66. Sensitivity and specificity were 73% and 50%. Regarding the nomogram by Pu et al., the AUROC was 0.67. Sensitivity and specificity were 65% and 60%. For the nomogram by Li et al., the AUROC was 0.67, while sensitivity and specificity were 56% and 71%.
Conclusion
The 3 selected nomograms were validated using an external international cohort and displayed interesting and comparable predictive values. Those nomograms may be used in clinical practice to estimate survival after PD for ductal adenocarcinoma.

Abstract
Introduction Total pancreatectomy for pancreatic ductal adenocarcinoma has historically been associated with substantial patient morbidity and mortality. Given advancements in perioperative and postoperative care, evaluation of the surgical treatment options for pancreatic adenocarcinoma should consider patient outcomes and long-term survival for total pancreatectomy compared with partial pancreatectomy. Methods The U.S. National Cancer Database was queried for patients undergoing total pancreatectomy or partial pancreatectomy for pancreatic adenocarcinoma during 1998-2006. Demographics, tumour characteristics, operative outcomes, 30-day mortality, 30-day readmission, additional treatment, and Kaplan-Meier survival curves were compared. Results The database query returned 807 patients who underwent total pancreatectomy and 5840 who underwent partial pancreatectomy. More patients who underwent total pancreatectomy than a partial pancreatectomy had a margin-negative resection (p < 0.0001). Mortality and readmission rates were similar in the two groups, as was long-term survival on Kaplan-Meier curves (p = 0.377). A statistically significant difference in the rate of surgery only (without additional treatment) was observed for patients in the total pancreatectomy group (p = 0.0003). Conclusions Although total compared with partial pancreatectomy was associated with a higher rate of margin-negative resection, median survival was not significantly different for patients undergoing either procedure. Patients who underwent total pancreatectomy were significantly less likely to receive adjuvant therapy.

Abstract
BACKGROUND Treatment of ruptured hepatocellular carcinoma (HCC) focuses on hemorrhage control and utilizes tumor vascular anatomy to palliate or temporize selected patients with hepatic artery embolization (HAE). Radiofrequency ablation (RFA) and microwave ablation (MWA) are feasible alternatives or adjunct modalities to resection of HCC; the method of energy delivery in MWA allows uniform coagulative necrosis in shorter time compared with RFA. CASE DESCRIPTION We present the case of an 82-year-old man who presented with a ruptured liver tumor with active intraperitoneal bleeding on angiography. The patient remained hemodynamically stable with evidence of ongoing bleeding following HAE. Tumor destruction and definitive hemostasis were obtained with minimally invasive MWA. CONCLUSION Tumor rupture remains a negative prognostic factor in the course of HCC. In select patients, MWA allows definitive hemorrhage control with minimal surgical morbidity.

Abstract
BACKGROUND Robotic pancreaticoduodenectomy (RP) has shown some advantages over open pancreaticoduodenectomy (OP) but no data has been published providing a cost comparison. METHODS Retrospective analysis of all pancreaticoduodenectomies at a single quaternary cancer referral center was performed. Patient demographics, comorbidities, operative characteristics, complications, and charge data were recorded, and then compared using standard statistical methods. RESULTS 71 pancreaticoduodenectomies were performed: 22 RP and 49 OP. Patients undergoing OP had similar demographics, comorbidities, pathology, and oncologic characteristics as patients undergoing RP. While operative charges were higher for RP, once inpatient stay associated costs and follow-up costs were included, there was no difference in total costs between RP and OP. CONCLUSIONS Patients undergoing RP have equivalent rates of R0 resection as OP, and benefit from decreased number of complications, surgical site infections, and length of stay in the intensive care unit. Once cost of complications and follow-up are incorporated, no significant difference between procedures exists. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
The number of available liver grafts is not sufficient to meet the current demand. A significant number of patients succumb before they receive a liver graft. However, approximately 10% of marginal livers are considered unsuitable for donation and are discarded. Calculating the primary non-function probability for any given liver graft can be performed using prognostic tools, such as the Donor Risk Index and the Eurotransplant Donor Risk Index. On the other hand, mortality on the waiting list, which is sometimes more than 15% per year of enlistment, directly correlates with its size, the graft supply and the gravity of the potential recipients' clinical condition. Up to 30% of the potential recipients will never receive a graft. The purpose of this invited commentary is to examine whether the literature supports the utilization of the marginal liver grafts that would otherwise be discarded. It appears that there is sufficient evidence in favor of the development of a "B-list" for potential liver graft recipients. It should comprise all of the candidates who were definitely removed from the primary waiting list or were never included. The potential "B-list" recipients should only be eligible to receive grafts that would otherwise be discarded, i.e., "B-livers". Enrollment in a "B-list" might not only increase the overall patient survival (enlisted and transplanted combined) but might also improve candidate quality of life by maintaining their hope for a cure.

Abstract
BACKGROUND AND AIM Induction with anti-thymocyte globulin (ATG) during solid organ transplantation is associated with an improved clinical course and leads to prolonged lymphopenia. This study aims to investigate whether prolonged lymphopenia, caused by ATG induction, has an impact on patient and graft survival following liver and kidney transplantation. PATIENTS AND METHODS This was a single-center, retrospective study. A total of 292 liver and 417 kidney transplants were performed with ATG induction (6 mg/kgr, divided into four doses), and the transplant recipients were followed for at least three months. The average lymphocyte count for the first 30 days after the operation was calculated, and the cut-off value for defining lymphopenia was arbitrarily set to ≤ 500 cells/mm(3). RESULTS There were 210 liver transplant recipients (71.9%) who achieved prolonged lymphopenia, whereas the remaining 82 recipients (28.1%) did not. The mean survival time of these patient groups was 10.27 and 12.71 years, respectively (p = 0.1217), and the mean graft survival time was 8.98 and 12.25 years, respectively (p = 0.0147). Of the kidney transplant patients, 330 (79.1%) recipients achieved prolonged lymphopenia, whereas the remaining 87 (20.9%) did not. The mean survival time of these patient groups was 13.94 and 14.59 years, respectively, (p = 0.4490), and the mean graft survival time was 11.84 and 11.54 years, respectively (p = 0.7410). CONCLUSION The efficacy and safety of ATG induction partially depend on decreased total lymphocyte counts. Following ATG induction in liver transplant recipients, a reasonable average lymphocyte count during the first postoperative month would be above 500 cells/mm(3).

Abstract
BACKGROUND Most deceased donor kidney allocation protocols are based on waiting time and do not take into account either recipient's life expectancy. This study investigates whether graft survival is affected by patient life expectancy. METHODS A total of 640 adult kidney transplants were performed. Recipients were divided in group A (patients ≤ 50 years) and group B (patients > 50 years). The status of graft+recipient combination was characterized as: a) deceased recipient with functional graft, b) alive recipient with functional graft and c) deceased or alive recipient with nonfunctional graft. RESULTS Mean kidney recipient survival was 15.15 (95% CI: 14.54, 15.77) and 12.40 (95% CI: 11.47, 13.33) years for groups A and B respectively (p < 0.0001). Mean graft survival was 13.62 (95% CI: 12.81, 14.43) and 12.42 (95% CI: 11.59, 13.25) years for groups A and B respectively (p=0.6516). Non-functional grafts were identified in 18.4% (n=57) and 16.4% (n=54) of group A and B respectively. CONCLUSIONS Allocation of renal grafts to older patients does not result in significant loss of graft-years. Recipients' life expectancy has a small impact on graft survival. We should not deviate from the basic principles of equality, when kidney allocation systems are designed.

Abstract
BACKGROUND AND AIM Hepatic artery thrombosis (HAT) occurs in 3% to 11% of all liver transplantations. Some authors have reported good outcomes with early thrombectomy. To investgate the impact of re-vascularization on graft survival. METHODS A total of 566 primary, cadaveric, single organ, adult liver transplants were performed. Hepatic arterial Doppler was performed routinely and patients with abnormal findings during the first two post-operative weeks were reexplored. Abnormal findings after this time-point were verified by non-invasive angiogram. The 47 patients that were diagnosed with arterial thrombosis, either intra-operatively or by angiogram, were divided into three groups. No further action was taken for group A, thrombectomy alone was performed for group B1, thrombectomy and anastomotic revision was employed for group B2. RESULTS Arterial thrombosis was diagnosed in 47 (8.3%) patients. Mean patient survival was 42, 62 and 98 months for groups A, B1 and B2 respectively (p: 0.0629). Mean graft survival was 24, 29 and 60 months for groups A, B1 and B2 respectively (p: 0.3386). Re-transplant incidence was 8.7%, 40% and 28.6% for groups A, B1, and B2 respectively (p: 0.035). CONCLUSIONS Early diagnosis of HAT by surveillance Doppler may lead to improved recipient survival secondary to earlier re-transplantation and not because of successful graft re-vascularization.

Abstract
We retrospectively evaluated the use of double-j stent and the incidence of urological complications in 2 groups of patients who received a kidney transplant. From January 2005 to September 2007 we studied 172 patients receiving kidney transplants, 65 and 107 from living and cadaver donors, respectively. From the 172 patients, a total of 34 were excluded due to ureterostomy or Politano-Leadbetter ureterovesical anastomosis. Another 21 patients were excluded from the study due to graft loss due to acute or hyperacute rejection, cytomegalovirus (CMV) infection, or vascular complication. The remaining patients were divided into 2 groups: group A (44 patients) and B (73 patients) with versus without the use of a double-j-stent, respectively. The 2 groups were comparable in terms of donor and recipient gender, ischemia time, and delayed graft function. We failed to observes significant differences between the 2 groups in mean hospital stay (23 +/- 9 and 19 +/- 9), urinary leak (2.3% and 4.1%), and urinary tract infection (20.4% and 19.2%), among groups A and B, respectively. The only difference observed concerned the gravity of the urinary leak; no surgical intervention was needed among the double-j stent group versus 2 patients demanding ureterovesical reconstruction in the nonstent group. In conclusion, our data suggested that the routine use of a double-j stent for ureterovesical anastomosis neither significantly increased urinary tract infection rates, nor decreased the incidence of urinary leaks, but may decrease the gravity of the latter as evidenced by the need for surgical intervention.

Abstract
In a 34 year-old woman complaining of right upper quadrant pain and having mildly elevated total bilirubin, the imaging investigation revealed a liver lesion with characteristics of focal nodular hyperplasia, measuring 3.8 cm, at the confluence of the hepatic veins. The mass was obstructing the left and middle hepatic veins and nearly obstructing the right hepatic vein. Dilation of the splenic vein with development of retropancreatic varices, splenomegaly and free abdominal fluid were also present. The patient underwent an uncomplicated left hemihepatectomy. Patients postoperative total bilirubin was normalized. Tomographic imaging three months after the liver resection revealed resolution of all the Budd-Chiari radiographic signs. This is a report of a case where a hepatic focal nodular hyperplasia, despite its benign nature, required extensive and urgent surgical intervention due to its location and potential dangers secondary to the development of portal hypertension.

Abstract
Two types of transplants are offered to patients with complicated insulin dependent diabetes mellitus: a) whole pancreas transplantation, b) pancreatic islet transplantation. A total of 29000 whole pancreas transplantations and 1500 islet transplantations have been performed worldwide until today. Patient survival for whole pancreas recipients is 85% five years after transplantation, whereas very few islet studies focus on patient survival. Graft survival for whole pancreas recipients is 90%, 70% and 45%, at one, five and ten years after transplantation respectively. On the other hand, only 44% of islet recipients are still insulin free, one year after engraftment. If the definition of a successful islet transplantation is not insulin independence but production of C-peptide, then 80% of the same islet recipients have a functioning graft by the end of the first post-transplant year. It is a known fact that whole pancreas transplantation has significant complications. The most common complications after whole organ transplantation include technical failures, acute rejection and CMV infection, whereas islet transplantation is associated with portal vein thrombosis, bleeding, emergency exploratory laparotomy, liver steatosis and rapamune-induced mouth ulcers. The cumulative cost of a whole organ transplantation is about ?40,000. On the other hand, the cumulative cost of a pancreatic islet transplant is estimated to be higher than ?120,000. Whole organ transplantation halts the late complications of diabetes, namely vasculopathy, retinopathy, nephropathy and neuropathy. Although similar claims are made for islet transplantation, its impact on long-term diabetic complications is possible but not proven. Currently, in North America, lean young donors are utilized for whole organ transplants, whereas overweight or older donors are utilized for islet transplants. In conclusion, although islet transplantation is an extremely promising therapy and probably the way of the future, whole organ transplant is still the gold standard according to evidence-based medicine.

Abstract
BACKGROUND Liver transplantation represents the main treatment for alcoholic cirrhosis. The goal of this article is to review the results of liver transplantation for alcoholic cirrhosis in Greece over the last 2 decades. METHODS Among 247 patients who underwent liver transplantation between 1991 and 2007, 34 (13.7%) experienced alcoholic cirrhosis as the primary diagnosis. We reviewed their demographic data, stage of liver disease, and outcomes regarding survival via a Kaplan-Meier curve. Also we analyzed the causes of death and the postoperative complications. RESULTS Mean Model for End-Stage Liver Disease (MELD) score was 18.4. Other diagnoses included hepatitis C virus (HCV; 23.5%), hepatitis B virus (HBV; 14.7%), and hepatocellular carcinoma (8.8%). Eleven patients died the most frequent causes being primary graft nonfunction (n = 3), hepatic artery thrombosis (n = 2), sepsis (n = 2), and portal vein thrombosis (n = 2). Complications included rejection (32.4%), infection (26.5%), hepatic graft dysfunction (11.8%), and recurrent HCV, recurrent HBV, and renal failure (8.8% each). Recurrence of alcoholism was observed in 3 patients (8.8%) with mild effects on liver function tests. There has been a significant increase in the number of liver transplantations for alcoholic cirrhosis in the last 6 years, namely 25 patients versus 9 in the previous 10 years. CONCLUSIONS We observed a significant increase in the frequency of alcoholic cirrhosis leading to liver transplantation in the last several years in Greece.

Abstract
AIM We have investigated CsA induced liver hyperplasia to explore the potential effects on the immunogenicity of the regenerating liver within the clinical context of rejection after transplantation. MATERIALS AND METHODS Flow cytometry analysis of hepatocytes, isolated 48 hours after 2/3 partial hepatectomy (PH2/3) or sham operation in rats, was performed to determine the effect of CsA on DNA synthesis and MHC molecule expression. The possible role of PGE2 was evaluated by the administration of SC-19220, an EP1-PGE2 receptor antagonist. RESULTS CsA augmented liver regeneration and this was partially attenuated by SC-19220. The moderate expression of class I MHC expression, as well as the very low class II MHC expression detected in normal hepatocytes by flow cytometry was augmented after PH2/3 and reduced by CsA. The CsA-mediated decrease of hepatocyte immunogenicity was not SC-19220 dependent. CONCLUSIONS It is proposed that the enhancing effect of CsA on hepatocyte proliferation is by means of an indirect mechanism that can be attributed to a) reduced immunogenicity of the regenerating liver as a result of inhibition of class I and II MHC hepatocyte expression and b) increased PGE2 synthesis in the liver mediated by its action on EP1 receptor.

Abstract
A 40-year-old male developed sepsis due to cholangitis. Five years earlier he underwent liver transplantation with hepaticojejunostomy. Over the past 18 months, he had 6 episodes of cholangitis. Radiologic studies demonstrated no biliary obstruction. Surgical intervention to eliminate bile reflux and stasis by lengthening the Roux-en-Y limb from 30 to 90 cm was curative. He has had no further episodes of cholangitis or hospitalization in the past 2 years. This case is the first description to our knowledge of a simple technique to treat recurrent cholangitis in patients with normal biliary anatomy, but inadequate biliary drainage following liver transplantation.

Abstract
Our center has performed 205 orthotopic liver transplantations (OLT) in 201 patients. Hepatocellular carcinoma (HCC) was discovered in 32 (15%) patients, 5 of whom were diagnosed incidentally in recipient explants. The main underlying diagnosis was viral hepatitis (n = 28; 87.5%). Most patients (17; 53.1%) were diagnosed as having Child class B cirrhosis. Single tumors measuring <3 cm were diagnosed in 29 (90.6%) patients. Downstaging chemoembolization was performed in 7 (21.8%) patients. Preoperative aFP levels were normal in 20 (62.5%) patients. In the rest (n = 12; 37.5%), aFP levels normalized immediately after the OLT. In the latter group, 2 patients had a delayed (2 years) postoperative increase in aFP levels; both patients had tumor recurrence in the graft. All patients with hepatitis B received antiviral treatment with HBIG and lamivudine. There were 9 deaths (28.1%) in the immediate postoperative period (<30 days). One-year survival rate was 62.5% (n = 20). Actuarial 5-year survival rate was 55%, and actuarial 10-year survival rate was 40%. In conclusion, OLT has become the standard treatment for patients diagnosed with HCC in a population that shows cirrhosis most of the time to be secondary to viral hepatitis, provided that recipients are selected according to the size of the neoplasm and that they receive adequate antiviral prophylaxis.

Abstract
Hepatic stellate cells (HSC) and endothelial cells of the liver sinusoids synthesize and degrade hyaluronan, respectively. The roles of these cell types in the biosynthesis and degradation of hyaluronan were studied during regeneration following partial hepatectomy. Pure cultures of HSC and liver endothelial cells (LEC) were obtained from regenerating liver at different stages using a Nycodenz gradient followed by discontinuous Percoll gradient. The HSC that established 3 or 4 days after partial hepatectomy synthesized large amounts of hyaluronan when cultured in the presence of fetal calf serum (FCS) or platelet-derived growth factor B-chain homodimer (PDGF)-BB. These cells, as well as LEC, expressed active PDGF beta-receptors. Furthermore, the ability of LEC to degrade hyaluronan was decreased at early stages of liver regeneration. The increased synthesis of hyaluronan by HSC and the failure of LEC to catabolize the polysaccharide resulted in elevated hyaluronan concentrations in the blood.
