Systematic Review and Meta-Analysis of the Outcomes After Hepatic Artery Reconstruction in Pediatric Liver Transplantation Using a Microscope Versus Surgical Loupe. Transplant Proc 2024:S0041-1345(24)00425-1. [PMID: 39164137 DOI: 10.1016/j.transproceed.2024.08.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Accepted: 08/06/2024] [Indexed: 08/22/2024]
Abstract
BACKGROUND To review the impact of the operating microscope (OM) for reconstruction of the hepatic artery (HA) by comparing the outcomes with standard loupe reconstruction (SL) in pediatric liver transplantation (LT). METHODS Studies comparing the application of OM and SL for the reconstruction of the HA in primary pediatric LT were included from a systematic search of MEDLINE, Cochrane Library and EMBASE from inception to June 2022. Re-transplantation, dual grafts and auxiliary transplants were excluded. Primary outcome was the rate of HA thrombosis (HAT). Secondary outcomes were graft loss and mortality. RESULTS There were 1261 liver recipients from 9 included studies published until June 2022. There were 484 patients in the OM group and 777 patients in the SL group. HAT incidence with OM was significantly lower with OR = 0.18 (95% CI: 0.07-0.48). The 1-year graft survival was significantly better in the OM group with OR = 2.77 (95% CI: 1.13-6.80). 1-year overall mortality was also significantly lower with OM with OR = 0.39 (0.18-0.86). The use of OM did not significantly impact the incidence of HAT in the living donor liver transplant subgroup. Differences in time for hepatic HA reconstruction, total operating time and length of hospital stay did not reach statistical significance. CONCLUSION The use of OM has reduced the risk of HAT, graft loss and mortality in pediatric liver transplantation. Adoption of microsurgical principles in general may have contributed to the improved outcomes with SL reconstruction of HA in pediatric LT.

Abstract
BACKGROUND The indication of living donor liver retransplantation (re-LDLT) for retransplant candidates with chronic allograft failure (CAF) is increasing because of the high mortality rate of patients on the waiting list. However, evidence supporting re-LDLT for CAF remains scarce because of technical difficulties. We aimed to examine the feasibility based on our significant case experience. METHODS A total of 95 retransplant cases (adult: 53, pediatric: 42) between 2000 and 2020 were retrospectively reviewed. Graft survival after re-LDLT and deceased donor liver retransplantation (re-DDLT) was compared among recipients with CAF and acute allograft failure (AAF). RESULTS Re-LDLTs for CAF were performed in 58 (61.1%) cases, re-DDLTs for CAF in 16 (16.8%) cases, re-LDLTs for AAF in 13 (13.7%) cases, and re-DDLTs for AAF in 8 (8.4%) cases. Re-DDLTs have become increasingly prevalent over time. Retransplantation for AAF results in lower graft survival than that for CAF in both adult and pediatric cases. All adult recipients who underwent re-LDLT for AAF died within 1 y after retransplantation. The 5-y graft survival between re-LDLT and re-DDLT for CAF was not significantly different (73.8% versus 75.0%, P = 0.84). Operation time and blood loss were not significantly different. CONCLUSIONS The survival rate of re-LDLT for recipients with CAF is permissible. Re-LDLT may be another treatment option for recipients with CAF.

A Systematic Review and Meta-Analysis: Do We Still Need Microscope Surgery in Hepatic Artery Anastomosis to Decrease the Incidence of Complications in Living Donor Liver Transplantation? Cureus 2023; 15:e48112. [PMID: 37920422 PMCID: PMC10619707 DOI: 10.7759/cureus.48112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/01/2023] [Indexed: 11/04/2023] Open
Abstract
Hepatic artery thrombosis (HAT) is the most serious vascular complication after liver transplantation (LT). Moreover, in comparison to deceased donor liver transplantation (DDLT), hepatic artery (HA) anastomosis is more challenging in living donor liver transplantation (LDLT) with a lot of controversial topics about the use of microscopic surgery. We aimed to compare the use of microscopic and loupe surgery in HA anastomosis in adult and pediatric LDLT to decrease the incidence of vascular complications. We searched PubMed, Scopes, Web of Science, and Cochrane Library for eligible studies from inception to April 2023 and a systematic review and a meta-analysis were done. According to our eligibility criteria, 10 studies with a total of 1939 patients were included. In comparison to microscopic surgery, loupe anastomosis has a similar incidence of HAT (thrombosis, risk ratio (RR) = 0.96, 95% CI = 0.26-3.48, P = 0.95). In addition to that, no significant difference was detected between the two types in terms of stenosis, decreased blood flow and hospital stay (decreased blood flow, RR = 0.68, 95% CI = 0.01-86.65, P = 0.88), (stenosis, RR = 1.81, 95% CI = 0.19-17.21, P = 0.60), (hospital stay, mean deviation (MD) = 1.16, 95% CI = -3.79-6.11, P = 0.65). However, the anastomotic time was longer in the case of microscopic surgery (anastomotic time, MD = 24.09, 95% CI = 7.79-40.39, P = 0.004). With an equal incidence of complications and longer anastomotic time, there is no added benefit of the routine use of microscopic surgery in HA anastomosis in LDLT.

Abstract
BACKGROUND Failure to achieve a good arterial inflow to the graft in living donor liver transplantation (LDLT) has disastrous consequences to the graft and patient survival. Standard microvascular techniques of hepatic artery (HA) anastomosis used in deceased donor liver transplantation are not applicable in LDLT. We present the results of our unique Backwall-first technique of HA anastomosis in both adult and pediatric LDLT. PATIENTS AND METHODS Retrospective review of all consecutive patients who underwent LDLT from January 2010 to December 2020 was performed from our prospective database. Data with regard to early postoperative (90-day) hepatic arterial complications were analyzed. RESULTS A total of 1276 LDLTs (876 adults, 400 children) were performed during the study period. In the 90-day postoperative period, HA anastomotic complications [thrombosis in 11 (0.9%); pseudoaneurysm in 3 (0.2%)] were observed in 14 recipients (1.1%) including 8 adults (0.9%) and 6 children (1.5%). Eight of these 14 recipients (0.6%) including 4 adults (0.5%) and 4 children (1%) had standard HA reconstruction. The remaining six (0.5%) including 4 adults and 2 children had complex arterial reconstruction with interposition graft and/or alternative arterial inflow. CONCLUSION The Backwall-first technique of HA reconstruction described in this study achieved a very low HA complication rate in LDLT.

Abstract
AIMS After liver transplantation (LT), synthesis of coagulation factors by the graft recovers faster for pro thrombotic than anti thrombotic factors, resulting in a potential pro thrombotic imbalance. We studied the thrombotic and hemorrhagic complications in our pediatric LT series, providing supplementation of fresh frozen plasma (FFP) and/or antithrombin (AT) in the prophylactic antithrombotic regimen. METHODS This was a retrospective observational single center study. All isolated pediatric LTs performed between 1/11/2009 and 31/12/2019 (n = 181) were included. Postoperatively, in addition to low molecular weight heparin, 22 patients (12%) received FFP (10 ml/kg twice daily for 10 days), 27 patients (15%) were given FFP (reduced duration) and AT (50-100 IU/kg/day if AT activity remained <70%), and 132 (73%) received AT only. Complications, outcome, and coagulation profiles in postoperative days 0-10 were analyzed. RESULTS In all three treatment groups, AT activity normalized by day 4 while prothrombin remained <70% of normal until day 9. Hepatic artery thrombosis (HAT), portal vein thrombosis (PVT), and hemorrhagic complications occurred in 2.8%, 3.3%, and 3.9% of LTs. One- and 5-year patient and graft survival were 88% (±2.4% Standard Error) and 84% (±2.5%), and 86% (±2.6%) and 84% (±2.7%), respectively, without difference between groups. HAT were associated with low AT on days 0 and 1, and PVT with low AT on day 0. CONCLUSIONS Low antithrombin activity after LT was associated with postoperative thromboses. FFP and/or AT supplementation allowed early normalization of AT activity, while thrombotic or hemorrhagic complications were rare, suggesting efficient and safe management of post-LT coagulopathy.

Abstract
Variations of the hepatic artery are very common, but they greatly increase the difficulty of surgery and the risk of complications in perihepatic surgeries such as liver transplantation, liver segmentectomy, and gastroduodenal surgery. Thus, it is important to precisely define the type of hepatic artery variant before surgery. However, there are often rare variants that cannot be defined with existing classifications. For example, the type of hepatic artery variant in the current case could not be classified with conventional classifications, and no such variation has been reported to date, involving two accessory left hepatic arteries from the common hepatic and left inferior phrenic arteries, respectively. Based on the existing 3DCT technology and the CRL classification method, which is applicable to the most common hepatic artery variants, we reviewed many rare variant types and proposed a new classification method (ex-CRL classification) for hepatic artery variations that do not fit the classic scope. The ex-CRL classification can accurately classify the vast majority of rare cases in the literature, greatly compensates for the limitations of current hepatic artery classifications, improves the generalization and understanding of rare cases, and reduces surgical complications.

Abstract
BACKGROUND Hepatic artery reconstruction is an essential part of liver transplantation. This difficult stage of the operation is even more demanding in living donor liver transplantation than in deceased donor liver transplantation. One of the most important advances in hepatic artery reconstruction for living liver grafts was the introduction of microsurgical techniques involving an operative microscope or surgical loupe. Many surgical reconstruction techniques have been used in this field. PURPOSE In this article, first, we will talk about the hepatic artery reconstruction techniques that are frequently used in deceased donor liver transplantation, and afterward, we will talk about the hepatic artery reconstruction techniques used in living donor liver transplantation, which include the hepatic artery reconstruction technique we use and call "one stay corner suture technique". CONCLUSIONS We think high-volume transplant centers should tend to develop a standardized technique for doing hepatic artery reconstruction with their teams. We think the "one stay corner suture technique" can be easily applied in centers that perform LDLT.

Abstract
BackgroundThe incidence of hepatic artery thrombosis in pediatric living donor liver transplantation (LDLT) is significantly higher than that in adults, and is closely related to the surgeon’s experience with hepatic artery anastomosis. However, there are few studies on the learning curve of hepatic artery anastomosis among surgeons.MethodsWe collected data related to 75 patients who underwent pediatric LDLT and hepatic artery anastomosis independently by the same surgeon. Cumulative sum method (CUSUM) was used to analyse the duration of hepatic artery anastomosis and determine the cut-off value. Patients were divided into two phases according to CUSUM. We analysed the intraoperative and postoperative data and survival outcomes of the included patients.ResultsTotal anastomosis duration decreased with an increased number of completed procedures, and the average duration was 42.4 ± 2.20 min. A cut-off value and two phases were identified: 1–43 cases and 44–75 cases. Intraoperative blood loss was significantly lower in phase 2 than in phase 1. The immediate functional changes of total bilirubin (TBIL) and direct bilirubin (DBIL) were significantly also lower in phase 2 than in phase 1. Other functional outcomes, postoperative complications, and the long-term survival rate were not significantly different between the two phases.ConclusionsTechnical competence in pediatric LDLT hepatic artery anastomosis may be achieved after completing 43 cases. It is a safe procedure with a surgical loupe that can be systematized and adopted by pediatric surgeons with sufficient experience via a relatively long learning curve.

Creating a Single Inflow Orifice From Living Donor Kidney Allografts With Multiple Renal Arteries. Transpl Int 2022; 35:10212.

Abstract
Background: Multiple renal arteries (MRA) are often encountered during living-donor kidney transplantation (LDKT), requiring surgeons to pursue complex renovascular reconstructions prior to graft implantation. With improvements in reconstruction and anastomosis techniques, allografts with MRA can be successfully transplanted with similar outcomes to allografts with a single renal artery. Here, we describe in detail various surgical techniques for reconstruction of MRA grafts with the intent of creating a single arterial inflow. Methods: We retrospectively reviewed the medical records of all LDKT recipients with laparoscopically procured MRA kidneys between March 2008 and July 2021. Recipient and donor characteristics, operative data, type of reconstruction, and recipient outcomes were analyzed. The primary outcomes were the incidence of developing delayed graft function (DGF) and/or a vascular or urological complication within 12 months post-transplant. Results: Seventy-three LDKT recipients of MRA donor allografts were evaluated. Two renal arteries (RA) were encountered in 62 allografts (84.9%) and three RA in 11 allografts (15.1%). Renal artery reconstruction was performed in 95.8% (70/73) of patients. Eighteen different reconstruction techniques of MRA were utilized, the most common being side-to-side anastomosis in allografts with two RA (N = 44) and side-to-side-to-side anastomosis in allografts with three RA (N = 4). Interposition grafting was performed in seven cases (9.6%). A single ostium was created in 69 cases (94.5%), and the median warm ischemia time was 27 (range 20–42) minutes. None of the patients developed DGF or post-operative vascular or urological complications. Median creatinine at 3, 6, and 12 months post-transplant remained stable at 1.1 mg/dl. With a median follow-up of 30.4 months post-transplant, only one graft failure has been observed–death-censored graft survival was 98.6%. Conclusion: Complex reconstruction techniques to create a single renal artery ostium for graft implantation anastomosis in allografts with MRA show acceptable warm ischemic times, with no increased risk of post-operative vascular or urological complications.

[PMID: 34719848 DOI: 10.1111/petr.14188] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 10/19/2021] [Accepted: 10/23/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION In pediatric liver transplantation (pLT), hepatic artery thrombosis (HAT) is associated with inferior transplant outcome. Hepatic artery reconstruction (HAR) using an operating microscope (OM) is considered to reduce the incidence of HAT. METHODS HAR using an OM was compared to a historic cohort using surgical loupes (SL) in pLT performed between 2009 and 2020. Primary endpoint was the occurrence of HAT. Secondary endpoints were 1-year patient and graft survival determined by Kaplan-Meier analysis and complications. Multivariate analysis was used to identify independent risk factors for HAT and adverse events. RESULTS A total of 79 pLTs were performed [30 (38.0%) living donations; 49 (62.0%) postmortem donations] divided into 23 (29.1%) segment 2/3, 32 (40.5%) left lobe, 4 (5.1%) extended right lobe, and 20 (25.3%) full-size grafts. One-year patient and graft survival were both 95.2% in the OM group versus 86.2% and 77.8% in the SL group (p = .276 and p = .077). HAT rate was 0% in the OM group versus 24.1% in the SL group (p = .013). One-year patient and graft survival were 64.3% and 35.7% in patient with HAT, compared to 93.9% and 92.8% in patients with no HAT (both p < .001). Multivariate analysis revealed HAR with SL (p = .022) and deceased donor liver transplantation (DDLT) (p = .014) as independent risk factors for HAT. The occurrence of HAT was independently associated with the need for retransplantation (p < .001) and biliary leakage (p = .045). CONCLUSION In pLT, the use of an OM is significantly associated to reduce HAT rate, biliary complications, and graft loss and outweighs the disadvantages of delayed arterial perfusion and prolonged warm ischemia time (WIT).

Analysis of Hepatic Arterial Reconstruction Technique Using Surgical Loupes for Living-Donor Liver Transplantation: Results From a Single Center. Transplant Proc 2021; 53:2929-2933. [PMID: 34756714 DOI: 10.1016/j.transproceed.2021.09.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 08/28/2021] [Accepted: 09/22/2021] [Indexed: 01/26/2023]
Abstract
BACKGROUND The reconstruction of the hepatic artery (HA) is the most complex step in living-donor liver transplantation (LDLT) owing to the artery's smaller diameter and the increased risk for HA-related complications. In this study, we presented our HA anastomosis technique for LDLT, which employed interrupted sutures using magnifying loupes. MATERIALS AND METHODS Since January 2019, we retrospectively analyzed 179 LDLTs that were performed at our center. HA anastomosis was performed under a loupes magnifier (2.5 or 4.5 × ) by the same surgeon. RESULTS There were 65 female and 114 male recipients with a mean age of 41.6 ± 21.6 years. Of the recipients, 34 were children. HA thrombosis (HAT) was seen in 3 recipients (1.67%; 1 child and 2 adults) in this series. HAT occurred on the third, sixth, and seventh days after LDLT. HAT was successfully treated with interventional radiologic technique. All recipients are still alive with a patent HA. CONCLUSION The use of magnifying surgical loupes and interrupted sutures to perform HA reconstruction is safe, feasible, and yields a low rate of HAT. Also, endovascular treatment can be used safely for treatment of HAT within the first week after LDLT with a high success rate and is not associated with major complications.

Abstract
BACKGROUND Living donor liver transplantation (LDLT) has expanded the availability of liver transplant but has been associated with early technical complications including the devastating complication of hepatic artery thrombosis (HAT), which has been reported to occur in 14% to 25% of LDLT using standard anastomotic techniques. Microvascular hepatic artery reconstruction (MHAR) has been implemented in an attempt to decrease rates of HAT. The purpose of this study was to review the available literature in LDLT, specifically related to MHAR to determine its impact on rates of posttransplant complications including HAT. METHODS A systematic review was conducted using PubMed/Medline and Web of Science. Case series and reviews describing reports of microscope-assisted hepatic artery anastomosis in adult patients were considered for meta-analysis of factors contributing to HAT. RESULTS In all, 462 abstracts were screened, resulting in 20 studies that were included in the meta-analysis. This analysis included 2,457 patients from eight countries. The pooled rate of HAT was 2.20% with an overall effect size of 0.00906. CONCLUSION Systematic literature review suggests that MHAR during LDLT reduces vascular complications and improves outcomes posttransplant. Microvascular surgeons and transplant surgeons should collaborate when technical challenges such as small vessel size, short donor pedicle, or dissection of the recipient vessel wall are present.

Abstract
Prior single center or registry studies have shown that living donor liver transplantation (LDLT) decreases waitlist mortality and offers superior patient survival over deceased donor liver transplantation (DDLT). The aim of this study was to compare outcomes for adult LDLT and DDLT via systematic review. A meta-analysis was conducted to examine patient survival and graft survival, MELD, waiting time, technical complications, and postoperative infections. Out of 8600 abstracts, 19 international studies comparing adult LDLT and DDLT published between 1/2005 and 12/2017 were included. U.S. outcomes were analyzed using registry data. Overall, 4571 LDLT and 66,826 DDLT patients were examined. LDLT was associated with lower mortality at 1, 3, and 5 years posttransplant (5-year HR 0.87 [95% CI 0.81-0.93], p < .0001), similar graft survival, lower MELD at transplant (p < .04), shorter waiting time (p < .0001), and lower risk of rejection (p = .02), with a higher risk of biliary complications (OR 2.14, p < .0001). No differences were observed in rates of hepatic artery thrombosis. In meta-regression analysis, MELD difference was significantly associated with posttransplant survival (R2 0.56, p = .02). In conclusion, LDLT is associated with improved patient survival, less waiting time, and lower MELD at LT, despite posing a higher risk of biliary complications that did not affect survival posttransplant.

Abstract
Criteria that drive the selection and utilization of living liver donors are limited. Herein, the global availability of living donor liver transplantation (LDLT) and components of donor selection and utilization were assessed via an international survey. There were 124 respondents representing 41 countries, including 47 from Asia/Middle East (A/ME), 20 from Europe, and 57 from the Americas. Responses were obtained from 94.9% of countries with ≥10 LDLT cases/year. Most centers (82.3%) have defined donor age criteria (median 18-60 years), while preset recipient MELD cutoffs (median 18-30) were only reported in 54.8% of programs. Overall, 67.5% of programs have preset donor BMI (body mass index) ranges (median 18-30), and the mean acceptable macrosteatosis was highest for A/ME (20.2 ± 9.2%) and lowest for Americas (16.5 ± 8.4%, P = 0.04). Americas (56.1%) and European (60.0%) programs were more likely to consider anonymous donors versus A/ME programs (27.7%, P = 0.01). There were no differences in consideration of complex anatomical variations. Most programs (75.9%) perform donor surgery via an open approach, and A/ME programs are more likely to use microscopic arterial reconstruction. Despite variations in practice, key aspects of living donor selection were identified. These findings provide a contemporary reference point as LDLT continues to expand into areas with limited access to liver transplantation.

Abstract
Aberrant donor hepatic artery anatomy or hepatic artery injury during organ procurement or recipient preparation poses a surgical challenge during deceased donor liver transplantation. In this study, we aimed to investigate arterial reconstruction using microvascular techniques during deceased donor liver transplantation and suggest reasonable indications for the microsurgical approach in this setting. We retrospectively reviewed the outcomes of 470 deceased donor liver transplantations performed at our institution between July 2011 and December 2015. Of these, 128 recipients underwent microsurgical hepatic artery reconstruction and 342 underwent reconstruction with surgical loupes. Thirty-two patients (6.8%) experienced hepatic artery-related complications, including hepatic artery thrombosis (n = 8, 1.7%). In the propensity score-matched cohort, the surgical loupe group showed a higher complication rate (P = .782). On multivariate analysis, cold ischemia time (odds ratio, 0.995; 95% confidence interval, 0.9920-0.999; P = .009) and use of aortohepatic conduits (odds ratio, 5.254; 95% confidence interval, 1.878-14.699; P = .002) were independent predictors of arterial complications. The low incidence of hepatic artery complications in this study is likely attributable to the active application of microsurgical techniques. Active application of back-table microsurgical plasty and selective application of microsurgical techniques for main arterial reconstruction may help minimize operative difficulties and arterial complications.

Abstract
PURPOSE Surgical resection is the only curative treatment for pancreatic cancer. Arterial resection and reconstruction during pancreaticoduodenectomy for advanced pancreatic cancer remain controversial due to a high rate of complications. METHODS We report two cases of pancreatic cancer with hepatic artery resection and reconstruction using the right gastroepiploic artery during pancreaticoduodenectomy after neoadjuvant therapy. RESULTS The patients underwent pancreaticoduodenectomy with resection of the right hepatic and common hepatic arteries. Achieving direct anastomosis was difficult; therefore, we planned hepatic artery reconstruction using the right gastroepiploic artery. We performed the reconstruction using an interrupted suture with end-to-end anastomosis. The first patient developed a postoperative pancreatic fistula, while the postoperative course of the second patient was uneventful. However, there were no adverse events related to the arterial reconstruction. R0 resection was achieved, and postoperative computed tomography revealed good patency of the reconstructed artery. CONCLUSION Hepatic artery reconstruction using the right gastroepiploic artery in pancreatic cancer might be technically safe and might become one of the alternative options.

Impact of Microsurgical Anastomosis of Hepatic Artery on Arterial Complications and Survival Outcomes After Liver Transplantation. Transplant Proc 2020; 53:65-72.

Abstract
Hepatic artery (HA) complications after liver transplant (LT) can lead to biliary complications, graft failure, and mortality. Although microsurgery has been established to improve anastomotic outcomes, it prolongs surgical time and has not reached widespread adoption at all transplant centers. We investigated the incidences of arterial, biliary complications and outcomes after using microsurgery to anastomose HA during LT. Retrospective cohort of consecutive LT performed from 2006 to 2018 was reviewed for operative details and postoperative outcomes. Cox-regression models were used to investigate the relationship between variables and outcomes. Eighty (62.5%) LTs (Group 1) were performed without and compared with 48 (Group 2) with microsurgical anastomosis of HA. Both groups were comparable in terms of arterial and biliary anastomoses performed. Incidence of early HA thrombosis was similar (6.2% vs 2.1%, P = .28). Group 2 had lower incidence of short- and long-term arterial complications, especially amongst living donor liver transplantations (LDLT) (5.3% vs 35.0%, P = .022). On multivariate analysis, microsurgery was associated with lower risk (hazard ratio [HR] 0.09, 95% confidence interval [CI] 0.01-0.71) of, and LDLT had higher risk (HR 4.23, 95% CI 1.46-12.27) of arterial complications. Biliary complications were associated with LDLT (HR 3.91, 95% CI 1.30-11.71) and dual biliary anastomoses (HR 5.26, 95% CI 1.15-24.08) but not with occurrence of HA complications. Worse patient survival was associated with the occurrence of any HA complication (HR 4.11, 95% CI 1.78-9.48). Hepatic arterial complications can be reduced using microsurgical techniques for the anastomosis, resulting in improved patient survival outcomes after liver transplantation.

Abstract
AIM To analyze the causes of liver retransplantation (LRT), which mostly depend on recipient factors. MATERIALS AND METHODS A descriptive, observational, and unicentric study including patients who underwent an LRT in a tertiary medical center between April 2002 and December 2018. Recipient, donor, and liver transplant data were collected. RESULTS During the period under review a total of 468 transplants were made; among them, 32 (6.8%) were LRT. The most common indication (25%) was hepatic artery thrombosis (HAT) developing ischemic cholangiopathy followed by chronic rejection (21.8%). Late LRT was performed in 71.8%. A total of 96.8% of donations were after brain death with a donor median age of 65 years. Six patients (18.7%) had HAT as a postoperative complication. The recipients' 3-, 6-, and 12-month overall survival was 72.7%, 54.6%, and 51.5%, respectively, and the 5-year was 46.8%. Leading cause of death was septic shock (42.1%). CONCLUSION In our patients, the most common cause of LRT is HAT. We had an LRT rate of 6.8%, which is consistent with national and international registers.

Abstract
PURPOSE Hepatic artery thrombosis (HAT) remains a life-threatening complication in liver transplantation. We aim to investigate the risk factors of HAT in deceased donor pediatric liver transplantation. METHODS 104 recipients from 2014 to 2016 were enrolled; donor and recipient characteristics, surgical variables, graft and recipient survival rate were compared between recipients with or without HAT. Univariate and multivariate analysis were applied to identify the risk factors of HAT. RESULTS The recipient survival rate was 87.0% and 96.3% at 1 year, and 87.0% and 96.3% at 3 years in HAT and non-HAT groups without significant difference. The graft survival rate was 73.9% and 96.3% at 1 year, and 73.9% and 95.1% at 3 years in HAT and non-HAT groups; significant difference was observed between two groups at both 1 and 3 years. Donor age less than 8.5 months, graft weight less than 190 g and GRWR less than 2.2% were identified as independent risk factors for HAT. Recipients with HAT were associated with higher incidence of post-operative biliary complications. CONCLUSIONS Young donor age and small liver graft are risk factors for HAT in deceased donor pediatric liver transplantation.

Abstract
BACKGROUND Liver transplantation is the treatment for end-stage liver diseases and well-selected malignancies. The allograft shortage may be alleviated with living donation. The initial UCLouvain experience of adult living-donor liver transplantation (LDLT) is presented. METHODS A retrospective analysis of 64 adult-to-adult LDLTs performed at our institution between 1998 and 2016 was conducted. The median age of 29 (45.3%) females and 35 (54.7%) males was 50.2 years (interquartile range, IQR 32.9-57.5). Twenty-two (34.4%) recipients had no portal hypertension. Three (4.7%) patients had a benign and 33 (51.6%) a malignant tumor [19 (29.7%) hepatocellular cancer, 11 (17.2%) secondary cancer and one (1.6%) each hemangioendothelioma, hepatoblastoma and embryonal liver sarcoma]. Median donor and recipient follow-ups were 93 months (IQR 41-159) and 39 months (22-91), respectively. RESULTS Right and left hemi-livers were implanted in 39 (60.9%) and 25 (39.1%) cases, respectively. Median weights of right- and left-liver were 810 g (IQR 730-940) and 454 g (IQR 394-534), respectively. Graft-to-recipient weight ratios (GRWRs) were 1.17% (right, IQR 0.98%-1.4%) and 0.77% (left, 0.59%-0.95%). One- and five-year patient survivals were 85% and 71% (right) vs. 84% and 58% (left), respectively. One- and five-year graft survivals were 74% and 61% (right) vs. 76% and 53% (left), respectively. The patient and graft survival of right and left grafts and of very small (<0.6%), small (0.6%-0.79%) and large (≥0.8%) GRWR were similar. Survival of very small grafts was 86% and 86% at 3- and 12-month. No donor died while five (7.8%) developed a Clavien-Dindo complication IIIa, IIIb or IV. Recipient morbidity consisted mainly of biliary and vascular complications; three (4.7%) recipients developed a small-for-size syndrome according to the Kyushu criteria. CONCLUSIONS Adult-to-adult LDLT is a demanding procedure that widens therapeutic possibilities of many hepatobiliary diseases. The donor procedure can be done safely with low morbidity. The recipient operation carries a major morbidity indicating an important learning curve. Shifting the risk from the donor to the recipient, by moving from the larger right-liver to the smaller left-liver grafts, should be further explored as this policy makes donor hepatectomy safer and may stimulate the development of transplant oncology.

Abstract
Background The immediate challenges during microvascular reconstruction of hepatic artery (HAR) during liver transplantation (LT) can be many. Hence, in order to give a cross sectional view of these problems this study over a period of 1 year, showing our routine practice, was taken up. Methods From January 2015 to December 2015, a total of 133 LTs were performed in Kaohsiung Chang Gung Memorial Hospital, Taiwan. All hepatic artery (HA) reconstructions were performed by a microvascular surgeon under an operating microscope. Results In the 133 patients, one artery was anastomosed in 123 (92.5%) patients, two in 9 (6.8%) patients and three in 1 (0.7%) of the patient. Eleven (8.3%) arteries were less than 2 mm in size (1-1.9 mm). There were intimal dissections (IDs) involving either the donor or the recipient arteries of mild to severe nature in 9 (6.8%) patients. Immediately following graft arterial anastomosis, either there was no flow or an intraoperative hepatic artery thrombosis (HAT) was found in nine (7.1%-8 LDLT, 4.8%-1 DDLT) patients. Immediate re-do anastomosis was done in all of these patients who did well in the follow-up. The overall post-operative success rate was 99.2%. One patient (0.8%) developed postoperative HAT due to infection during follow up and died due to sepsis. Conclusions Small vessels or HA injury are the frequently encountered problems by a micro vascular surgeon. The other problems could be ID, need to do multiple reconstructions, immediate HAT and ability to re-do the HAR immediately.

Abstract
BACKGROUND There is paucity of data about the impact of using magnification on rate of pancreatic leak after pancreaticoduodenectomy (PD). The aim of this study was to show the impact of using magnifying surgical loupes 4.0× EF (electro-focus) on technical performance and surgical outcomes of PD. PATIENTS AND METHOD This is a propensity score-matched study. Thirty patients underwent PD using surgical loupes at 4.0× magnification (Group A), and 60 patients underwent PD using the conventional method (Group B). The primary outcome was postoperative pancreatic fistula. Secondary outcomes included operative time, intraoperative blood loss, postoperative complications, mortality, and hospital stay. RESULTS The total operative time was significantly longer in the loupe group ( P = .0001). The operative time for pancreatic reconstruction was significantly longer in the loupe group ( P = .0001). There were no significant differences between both groups regarding hospital stay, time to oral intake, total amount of drainage, and time of nasogastric tube removal. Univariate and multivariate analyses demonstrated 3 independent factors of development of postoperative pancreatic fistula: pancreatic duct <3 mm, body mass index >25, and soft pancreas. CONCLUSION Surgical loupes 4.0× added no advantage in surgical outcomes of PD with regard to improvement of postoperative complications rate or mortality rate.
