Transplant Proc 2023; 55:2444-2449. [PMID: 37891019 DOI: 10.1016/j.transproceed.2023.09.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 07/18/2023] [Accepted: 09/22/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND We aimed to identify risk factors associated with reoperation for postoperative intraperitoneal hemorrhage (PIH) after orthotopic liver transplantation and investigate if partial liver transplantation (PLT) increases the risk of PIH. METHODS We retrospectively analyzed the medical records of 304 consecutive recipients who underwent orthotopic liver transplantation at the Affiliated Lihuili Hospital, Ningbo University, from January 2016 to July 2022. Data were compared between recipients who experienced PIH requiring reoperation and those who did not. Subgroup propensity score matching analysis was performed to assess the impact of PLT on PIH risk. Neither prisoners nor participants who were coerced or paid were used in the study. RESULTS Among the 304 recipients, 22 (7.2%) underwent reoperation for PIH. Multivariate analysis revealed that the recipient Model for End-Stage Liver Disease (MELD) score (odds ratio = 1.066, 95% CI [1.025-1.109], P = .001) and volume of intraoperative packed red blood cell transfusion (odds ratio = 1.089, 95% CI [1.032-1.481], P = .002) were independent risk factors for PIH. No significant differences were observed in the risk of PIH between PLT and whole liver transplantation. CONCLUSION Preoperative MELD score and intraoperative packed red blood cell transfusion should be carefully considered to manage the risk of PIH in liver transplantation recipients. Partial liver transplantation, a crucial approach for addressing donor shortages, does not increase the risk of reoperation for PIH in recipients.

Abstract
Background Liver transplantation (LT) is widely recognized as a life-saving therapy for patients with end-stage liver disease. However, due to certain posttransplant complications, reoperations or endovascular interventions may be necessary to improve patient outcomes. This study was conducted to examine reasons for reoperation during the initial hospital stay following LT and to identify its predictive factors. Methods We evaluated the incidence and etiology of reoperation in 133 patients who underwent LT from brain-dead donors over a 9-year period based on our experiences. Results A total of 52 reoperations were performed for 29 patients, with 17 patients requiring one reoperation, seven requiring two, three requiring three, one requiring four, and one requiring eight. Four patients underwent liver retransplantation. The most common cause of reoperation was intra-abdominal bleeding. Hypofibrinogenemia was identified as the sole predisposing factor for bleeding. Frequencies of comorbidities such as diabetes mellitus and hypertension did not differ significantly between groups. Among patients who underwent reoperation due to bleeding, the mean plasma fibrinogen level was 180.33±68.21 mg/dL, while among reoperated patients without bleeding, it was 240.62±105.14 mg/dL (P=0.045; standard mean difference, 0.61; 95% confidence interval, 0.19-1.03). The initial hospital stay was significantly longer for the reoperated group (47.5±15.5 days) than for the non-reoperated group (22.5±5.5 days). Conclusions Meticulous pretransplant assessment and postoperative care are essential for the early identification of predisposing factors and posttransplant complications. In order to enhance graft and patient outcomes, any complications should be addressed without hesitation, and appropriate intervention or surgery should not be delayed.

Abstract
This study used the prospective National Surgical Quality Improvement Program (NSQIP) Transplant pilot database to analyze surgical complications after liver transplantation (LT) in LT recipients from 2017-2019. The primary outcome was surgical complication requiring intervention (Clavien-Dindo grade II or greater) within 90 days of transplant. Of the 1684 deceased donor and 109 living donor LT cases included from 29 centers, 38% of deceased donor liver recipients and 47% of living donor liver recipients experienced a complication. The most common complications included biliary complications (19% DDLT; 31% LDLT), hemorrhage requiring reoperation (14% DDLT; 9% LDLT) and vascular complications (6% DDLT; 9% LDLT). Management of biliary leaks (35.3% ERCP, 38.0% percutaneous drainage, 26.3% reoperation) and vascular complications (36.2% angioplasty/stenting, 31.2% medication, 29.8% reoperation) was variable. Biliary (aHR 5.14, 95% CI 2.69-9.8, p<0.001), hemorrhage (aHR 2.54, 95% CI 1.13-5.7, p = 0.024) and vascular (aHR 2.88, 95% CI 0.85-9.7, p = 0.089) complication status at 30-days post-transplant were associated with lower 1-year patient survival. We conclude that biliary, hemorrhagic and vascular complications continue to be significant sources of morbidity and mortality for LT recipients. Understanding the different risk factors for complications between deceased and living donor liver recipients and standardizing complication management represent avenues for continued improvement.

Abstract
Background Transfusion of blood products during orthotopic liver transplantation (OLT) is associated with increased morbidity and mortality. Although risk factors associated with intraoperative transfusion requirements have been widely assessed, published data on the prediction of postoperative transfusion requirements are sparse. Objectives The aim of this study was to evaluate risk factors for postoperative allogeneic transfusion requirements in OLT. Methods Clinical characteristics and intraoperative parameters of 645 consecutive adult patients undergoing OLT were retrospectively reviewed. Multivariate logistic regression was used to determine the main determinants for postoperative transfusion requirements. Results Determinants of postoperative transfusion requirements of any blood product in the postoperative period were the number of blood products transfused in the intraoperative period (OR 1.17, 95% CI 1.08-1.28), warm ischemia time (OR 1.05, 95% CI 1.02-1.08), MELD score (OR 1.05, 95% CI 1.01-1.08) and hepatocellular carcinoma (OR 0.45, 95% CI 0.28-0.72). A dose-dependent effect between the number of units transfused in the intraoperative period and transfusion requirements in the postoperative period was also observed. The relative risk of postoperative allogeneic transfusion of any blood component was 5.9 (95% CI 3.4-10.4) for patients who received 1-2 units in the intraoperative period, 7.3 (95% CI 3.6-14.7) for those who received 3-5 units in the intraoperative period, and 11.1 (95% CI 4.7-26.4) for those who received 6 or more units, when compared to no intraoperative blood transfusion. Conclusion Our study demonstrated an association between intraoperative transfusion and warm ischemia time with postoperative transfusion requirements. The identification of risk factors for transfusion in the postoperative period may improve management of these patients by increasing awareness to bleeding complications in this high-risk population and by expanding hemostasis monitoring to the postoperative period.

Abstract
The shortage of suitable organs is the biggest obstacle for transplants. At present, most organs for transplant in the United States are from donation after neurologic determination of death (brain death). Potential organs for transplant need to maintain their viability during a series of insults, including the original disease, physiologic derangements during the dying process, ischemia, and reperfusion. Proper donor management before, during, and after procurement has potential to increase the number and quality of organs from donors. Anesthesiologists need to understand the physiologic derangements associated with brain death and the updated donor management during the periprocurement period.

Abstract
BACKGROUND Glucose control can be difficult in the intraoperative and immediate postoperative period of liver transplantation. Hyperglycemia and glucose variability have been associated with acute kidney injury (AKI) in critically ill patients. We performed a retrospective study to test the hypothesis that perioperative glucose levels represented by time-weighted average glucose levels and glucose variability are independently associated with the incidence of postoperative AKI in patients undergoing liver transplantation. METHODS On the basis of blood glucose levels during liver transplantation and the initial 48 hours postoperatively, adult liver transplant recipients were classified into 4 groups according to their time-weighted average glucose: normoglycemia (80-200 mg/dL), mild hyperglycemia (200-250 mg/dL), moderate hyperglycemia (250-300 mg/dL), and severe hyperglycemia (>300 mg/dL) group. Patients were also classified into quartiles depending on their glucose variability, defined as the standard deviation of glucose measurements. The primary outcome was postoperative AKI. RESULTS AKI after liver transplantation was more common in the patients with greater perioperative glucose variability (first versus third quartile; OR, 2.47 [95%CI, 1.22-5.00], P = .012; first versus fourth quartile; OR, 2.16 [95% CI, 1.05-4.42], P = .035). CONCLUSIONS Our study suggests that increased perioperative glucose variability, but not hyperglycemia, is independently associated with increased risk of postoperative AKI in liver transplantation recipients.

Abstract
We retrospectively analyzed the causes, risk factors, and impact of early relaparotomy after adult-to-adult living donor liver transplantation (LDLT) on the posttransplant outcome. Adult recipients who underwent initial LDLT at our institution between August 1997 and August 2015 (n = 196) were included. Any patients who required early retransplantation were excluded. Early relaparotomy was defined as surgical treatment within 30 days after LDLT. Relaparotomy was performed 66 times in 52 recipients (a maximum of 4 times in 1 patient). The reasons for relaparotomy comprised postoperative bleeding (39.4%), vascular complications (27.3%), suspicion of abdominal sepsis or bile leakage (25.8%), and others (7.6%). A multivariate analysis revealed that previous upper abdominal surgery and prolonged operative time were independent risk factors for early relaparotomy. The overall survival rate in the relaparotomy group was worse than that in the nonrelaparotomy group (6 months, 67.3% versus 90.1%, P < 0.001; 1 year, 67.3% versus 88.6%, P < 0.001; and 5 years, 62.6% versus 70.6%, P = 0.06). The outcome of patients who underwent 2 or more relaparotomies was worse compared with patients who underwent only 1 relaparotomy. In a subgroup analysis according to the cause of initial relaparotomy, the survival rate of the postoperative bleeding group was comparable with the nonrelaparotomy group (P = 0.96). On the other hand, the survival rate of the vascular complication group was significantly worse than that of the nonrelaparotomy group (P = 0.001). Previous upper abdominal surgery is a risk factor for early relaparotomy after LDLT. A favorable longterm outcome is expected in patients who undergo early relaparotomy due to postoperative bleeding.

Abstract
UNLABELLED Intraabdominal hemorrhage remains one of the most frequent surgical complications after liver transplantation. The aim of the study was to evaluate risk factors for intraabdominal bleeding requiring reoperation and to assess the relevance of the reoperations with respect to short- and long-term outcomes following liver transplantation. MATERIAL AND METHODS Data of 603 liver transplantations performed in the Department of General, Transplant and Liver Surgery in the period between January 2011 and September 2014 were analyzed retrospectively. Study end-points comprised: reoperation due to bleeding and death during the first 90 postoperative days and between 90 postoperative day and third post-transplant year. RESULTS Reoperations for intraabdominal bleeding were performed after 45 out of 603 (7.5%) transplantations. Low pre-transplant hemoglobin was the only independent predictor of reoperation (p=0.002) with the cut-off of 11.3 g/dl. Postoperative 90-day mortality was significantly higher in patients undergoing reoperation as compared to the remaining patients (15.6% vs 5.6%, p=0.008). Post-transplant survival from 90 days to 3 years was non-significantly lower in patients after reoperation for bleeding (83.3%) as compared to the remaining patients (92.2%, p=0.096). Nevertheless, multivariable analyses did not reveal any significant negative impact of reoperations for bleeding on short-term mortality (p=0.589) and 3-year survival (p=0.079). CONCLUSIONS Surgical interventions due to postoperative intraabdominal hemorrhage do not appear to affect short- and long-term outcomes following liver transplantation. Preoperative hemoglobin concentration over 11.3 g/dl is associated with decreased risk of this complication, yet the clinical relevance of this phenomenon is doubtful.

Abstract
Liver transplantation (LT) was historically associated with massive blood loss and transfusion. Over the past two decades transfusion requirements have reduced dramatically and increasingly transfusion-free transplantation is a reality. Both bleeding and transfusion are associated with adverse outcomes in LT. Minimising bleeding and reducing unnecessary transfusions are therefore key goals in the perioperative period. As the understanding of the causes of bleeding has evolved so too have techniques to minimize or reduce the impact of blood loss. Surgical “piggyback” techniques, anaesthetic low central venous pressure and haemodilution strategies and the use of autologous cell salvage, point of care monitoring and targeted correction of coagulopathy, particularly through use of factor concentrates, have all contributed to declining reliance on allogenic blood products. Pre-emptive management of preoperative anaemia and adoption of more restrictive transfusion thresholds is increasingly common as patient blood management (PBM) gains momentum. Despite progress, increasing use of marginal grafts and transplantation of sicker recipients will continue to present new challenges in bleeding and transfusion management. Variation in practice across different centres and within the literature demonstrates the current lack of clear transfusion guidance. In this article we summarise the causes and predictors of bleeding and present the evidence for a variety of PBM strategies in LT.

Abstract
Diabetogenic traits in patients undergoing liver transplantation (LT) are exacerbated intraoperatively by exogenous causes, such as surgical stress, steroids, blood transfusions, and catecholamines, which lead to intraoperative hyperglycemia. In contrast to the strict glucose control performed in the intensive care unit, no systematic protocol has been developed for glucose management during LT. Intraoperative blood glucose concentrations typically exceed 200 mg/dL in LT, and extreme hyperglycemia (> 300 mg/dL) is common during the neohepatic phase. Only a few retrospective studies have examined the relationship between intraoperative hyperglycemia and post-transplant complications, with reports of infectious complications or mortality. However, no prospective studies have been conducted regarding the influence of intraoperative hyperglycemia in LT on post-transplant outcome. In addition to absolute blood glucose values, the temporal patterns in blood glucose levels during LT may serve as prognostic features. Persistent neohepatic hyperglycemia (without a decline) throughout LT is a useful indicator of early graft dysfunction. Moreover, intraoperative variability in glucose levels may predict the need for reoperation for hemorrhage after LT. Thus, there is an urgent need for guidelines for glucose control in these patients, as well as prospective studies on the impact of glucose control on various post-transplant complications. This report highlights some of the recent studies related to perioperative blood glucose management focused on LT and liver disease.

Abstract
Introduction. This study's objective was to identify risk factors associated with reoperation for bleeding following liver transplantation (LTx). Methods. A retrospective study was performed at a single institution between 2001 and 2012. Operative reports were used to identify patients who underwent reoperation for bleeding within 2 weeks following LTx (operations for nonbleeding etiologies were excluded). Results. Reoperation for bleeding was observed in 101/928 (10.8%) of LTx patients. The following characteristics were associated with reoperation on multivariable analysis: recipient MELD score (OR 1.06/MELD unit, 95% CI 1.03, 1.09), number of platelets transfused (OR 0.73/platelet unit, 95% CI 0.58, 0.91), and aminocaproic acid utilization (OR 0.46, 95% CI 0.27, 0.80). LTx patients who underwent reoperation for bleeding had a longer ICU stay (5 days ± 7 versus 2 days ± 3, P < 0.001) and hospitalization (18 days ± 9 versus 10 days ± 18, P < 0.001). The risk of death increased in patients who underwent reoperation for bleeding (HR 1.89, 95% CI 1.26, 2.85). Conclusion. Reoperation for bleeding following LTx was associated with increased resource utilization and recipient mortality. A lower threshold for intraoperative platelet transfusion and antifibrinolytics, especially in patients with high lab-MELD score, may decrease the incidence of reoperation for bleeding following LTx.

Liver Transplantation without Perioperative Transfusions Single-Center Experience Showing Better Early Outcome and Shorter Hospital Stay. J Transplant 2013; 2013:649209. [PMID: 24455193 PMCID: PMC3876589 DOI: 10.1155/2013/649209] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2013] [Accepted: 11/17/2013] [Indexed: 12/14/2022] Open
Abstract
Background. Significant amounts of red blood cells (RBCs) transfusions are associated with poor outcome after liver transplantation (LT). We report our series of LT without perioperative RBC (P-RBC) transfusions to evaluate its influence on early and long-term outcomes following LT. Methods. A consecutive series of LT between 2006 and 2011 was analyzed. P-RBC transfusion was defined as one or more RBC units administrated during or ≤48 hours after LT. We divided the cohort in “No-Transfusion” and “Yes-Transfusion.” Preoperative status, graft quality, and intra- and postoperative variables were compared to assess P-RBC transfusion risk factors and postoperative outcome. Results. LT was performed in 127 patients (“No-Transfusion” = 39 versus “Yes-Transfusion” = 88). While median MELD was significantly higher in Yes-Transfusion (11 versus 21; P = 0.0001) group, platelet count, prothrombin time, and hemoglobin were significantly lower. On multivariate analysis, the unique independent risk factor associated with P-RBC transfusions was preoperative hemoglobin (P < 0.001). Incidence of postoperative bacterial infections (10 versus 27%; P = 0.03), median ICU (2 versus 3 days; P = 0.03), and hospital stay (7.5 versus 9 days; P = 0.01) were negatively influenced by P-RBC transfusions. However, 30-day mortality (10 versus 15%) and one- (86 versus 70%) and 3-year (77 versus 66%) survival were equivalent in both groups. Conclusions. Recipient MELD score was not a predictive factor for P-RBC transfusion. Patients requiring P-RBC transfusions had worse postoperative outcome. Therefore, maximum efforts must be focused on improving hemoglobin levels during waiting list time to prevent using P-RBC in LT recipients.
