Management of Budd-Chiari syndrome (BCS) has improved over the last decades. The main aim was to evaluate the contemporary post-liver transplantant (post-LT) outcomes in Europe.
Data from all ...patients who underwent transplantation from 1976 to 2020 was obtained from the European Liver Transplant Registry (ELTR). Patients < 16 years with secondary BCS or HCC were excluded. Patient survival (PS) and graft survival (GS) before and after 2000 were compared. Multivariate Cox regression analysis identified predictors of PS and GS after 2000. Supplemental data was requested from all ELTR-affiliated centers and received from 44. In all, 808 patients underwent transplantation between 2000 and 2020. One-, 5- and 10-year PS was 84%, 77%, and 68%, and GS was 79%, 70%, and 62%, respectively. Both significantly improved compared to outcomes before 2000 ( p < 0.001). Median follow-up was 50 months and retransplantation rate was 12%. Recipient age (aHR:1.04,95%CI:1.02-1.06) and MELD score (aHR:1.04,95%CI:1.01-1.06), especially above 30, were associated with worse PS, while male sex had better outcomes (aHR:0.63,95%CI:0.41-0.96). Donor age was associated with worse PS (aHR:1.01,95%CI:1.00-1.03) and GS (aHR:1.02,95%CI:1.01-1.03). In 353 patients (44%) with supplemental data, 33% had myeloproliferative neoplasm, 20% underwent TIPS pre-LT, and 85% used anticoagulation post-LT. Post-LT anticoagulation was associated with improved PS (aHR:0.29,95%CI:0.16-0.54) and GS (aHR:0.48,95%CI:0.29-0.81). Hepatic artery thrombosis and portal vein thrombosis (PVT) occurred in 9% and 7%, while recurrent BCS was rare (3%).
LT for BCS results in excellent patient- and graft-survival. Older recipient or donor age and higher MELD are associated with poorer outcomes, while long-term anticoagulation improves both patient and graft outcomes.
Abstract Introduction Vascular complications show an 8%–15% incidence after liver transplantation and represent an important cause of mortality. An aggressive policy is necessary for an early ...diagnosis and treatment. Patients and methods From 2001 to 2009, we performed 240 liver transplantations in 232 patients. We employed Doppler ultrasonography on days 1 and 4 as well as before hospital discharge and always try a radiological approach. Results The incidence of vascular complications was 7.2% ( n = 18) including arterial ( n = 12, 4.8%) of early thrombosis ( n = 4), late thrombosis ( n = 4), and stenosis ( n = 4) or portal ( n = 3; 1.2%) of thrombosis ( n = 2) or stenosis ( n = 1); or caval complications ( n = 3, 1.2%). Radiologic therapy was effective in 1 patient with arterial stenosis, in the 3 patients with portal complications, and in 2 patients with caval complications. All patients with early thrombosis and 2/4 with late thrombosis required retransplantation. Surgical treatment was effective in 1 patient with late thrombosis, 3 with stenosis, and 2 with caval complications. The overall mortality rate was 16.6%; 2 patients with arterial complications and 1 with a caval complications. Conclusion Vascular complications, mainly artery complications, represent serious problem after liver transplantation, which often requires retransplantation. With an aggressive policy of diagnosis and treatment, we can decrease the mortality rate from these adverse events.
Abstract Survival after orthotopic liver transplantation (OLT) has increased over the last decades, focusing on the metabolic complications that contribute to patient morbidity and mortality. The aim ...of our study was to describe the prevalence of metabolic syndrome (MS), its components, and its associated factors in patients who underwent OLT in a hospital in Spain. From November 2001 to January 2014, we performed 415 transplantations in 386 patients. We analyzed 204 patients with a minimum follow-up of 1 year (77.6% were male and the mean age was 54.2+/−9.5 years). The most frequent etiology was alcohol (41%), followed by hepatitis C virus (29.1%). The indication was decompensated cirrhosis in 51.8% and hepatocellular carcinoma in 34%. According to modified National Cholesterol Education Program–Adult Treatment Panel-III (NCEP-ATP III) criteria, 5 years post-transplantation MS was diagnosed in 38.2% of patients. Significant independent predictors of post-transplantation MS on logistic regression analysis were as follows: pretransplantation obesity (odds ratio OR, 3.09; P = .056), 1-year post-transplantation obesity (OR, 3.95; P = .009), pretransplantation diabetes (OR, 4.63; P = .001), 1-year post-transplantation diabetes (OR, 3.01; P = .015), 1-year post-transplantation hypertension (OR, 1.85; P = .176), and hypertriglyceridemia at the first year after transplantation (OR, 2.32; P = .063). In our center the prevalence of MS at 5 years after OLT is slightly lower than published. The most important risk factors were obesity and diabetes (both pretransplantation and the first year post-transplantation).
Portal vein thrombosis (PVT) is a relatively common finding in patients undergoing liver transplantation. Although the recommendation to prevent its recurrence is anticoagulation for a duration of 3 ...to 6 months, this is controversial.
The aim of our study was to determine the efficacy of oral anticoagulants (OAC) as prophylaxis for recurrent PVT after liver transplantation.
Our study included 215 liver transplant patients who underwent surgery in our center from January 2012 to August 2017. We selected all patients diagnosed with PVT either pre-transplantation (using Doppler echography or Angio-CT) or during transplant surgery. All patients with PVT were initially anticoagulated with low-molecular-weight heparin in the postoperative period; at discharge they received OAC for a duration of six months. Control Doppler ultrasound was performed at 3, 6, and 12 months post-transplantation.
PVT was identified in 37 out of 215 patients (17.2%). PVT was diagnosed with a pre-transplant vascular study in 17 out of 37 cases (45.9%). All patients were anticoagulated with OAC (warfarin) for at least 6 months. There were no cases of recurrent thrombosis and no complications associated with anticoagulant treatment throughout the follow-up period.
The prevalence of portal thrombosis in liver transplant patients in our study was fairly high, at 17.2%. PVT was identified in nearly 50% of patients using high-quality vascular studies prior to transplant surgery. Anticoagulation with OAC for 6 months was effective in preventing a recurrence of thrombosis and there were no associated complications.
Abstract Background Some variations of hepatic artery, which show 30% incidence, must be taken into account to avoid damage to the liver transplant during harvesting, we analyzed the incidence of ...variations and their influence on postoperative results. Patients and methods We performed a retrospective study of 325 liver transplantation between 2001 and December 2011. Results Variations in the hepatic artery were detected in 91 transplantations (32%) including 29 donors (8.9%), 57 recipients (17.5%), and 5 both (1.5%). The main variation among donors was a right hepatic artery originating from the mesenteric artery (38.2%), and a left hepatic artery from the left gastric artery (35.3%). Recipients showed the same distribution: RHA-UMA (right hepatic artery from upper mesenteric artery) (38.7%) and LHA-LGA (left hepatic artery from left gastric artery) (12.9%). 48.5% of donor hepatic variations did not need bench reconstruction, but all RHA-UMA required it mainly due to the donor gastroduodenal artery (7; 58%) We did not observe significant difference in cold or warm ischemia time, surgical time, red blood cell requirement, postoperative mortality, or overall survival when there was or was not an arterial anomaly. But arterial complications were more frequent in cases where there were recipient anomalies or both versus without anomalies or with donor anomalies (20%, 7,8%, 0%, 5,6%; P = .06). Donor RHA-UMA was associated with worse overall survival (69, 2%; P = .07) and longer cold ischemia time and red blood requirement. Bench reconstruction held to longer cold ischemia time and blood cell requirements ( P = .01) and shorter overall survival (82.4%). RHA-UMA was associated ( P = .08) with worse actuarial survival and a needed for bench reconstruction ( P = .01). Conclusion One must be careful during liver harvest to detect hepatic artery variations to avoid damage. Hepatic artery anomalies do not influence liver transplant results except for the presence of an RHA from the UMA with a need for bench reconstruction.
Abstract Introduction Liver transplantation (OLT) has been advocated as a good management option for patients with carcinoma hepatocellular (HCC). More recurrences are extrahepatic due to many ...pathological factors. Patients and Methods From April 1986 to December 2003, we performed 95. OLTs for HCC including 73% men of mean age of 54.7 years and 25.3% not filling Mazzaferro’s criteria. Results The recurrence incidence was 15.8% ( n = 15), including only extrahepatic lesions in 11 (mainly lung recurrence, seven) and hepatic plus extrahepatic in four. Main late mortality was due to tumor recurrence ( n = 12, 33.3%). No differences were observed among sex, preoperative chemoembolization, age, Child, Okuda, etiology, or satellite nodules. A greater incidence of tumor recurrence was observed with a preoperative biopsy (45.5% vs 5.9%, P = .0001); and alpha fetoprotein (AFP) > 200 ng/mL (37.5% vs 13.3%, P = .08); known HCC (25.5% vs 3.1%, P = .008); vascular invasion (42.1% vs 10.3%, P = .001); > 5 cm single nodule (50% vs 13%, P = .004); more than three nodules (50% vs 13.9%, P = .01); moderately to poorly differentiated tumors (37.5% vs 12.7%, P = .01); pTNM IV (50% vs 8.7%, P = .0001); and not meeting Milan criteria (40.9% vs 9.2%, P = .001). These are the same factors for extrahepatic recurrence. For hepatic recurrence the prognostic factors were: vascular invasion (15.8% vs 1.5%, P = .008), more than three nodules (25% vs 2.5%, P = .004), moderately to poorly differentiated tumors (18.8% vs 1.4%, P = .003), pTNM IV (16.7% vs 1.4%, P = .006), and not meeting Milan criteria (13.6% vs 1.5%, P = .01). Conclusions Recurrence incidence with Milan criteria was less than 10%, mainly extrahepatic (lung). Prognostic factors for tumor recurrence were pathological features, namely vascular invasion, more than three nodules, size larger than 5 cm, moderately to poorly differentiated tumors, pTNM IV stage. The use of preoperative chemoembolization did not decrease the recurrence rate. A preoperative biopsy increased the incidence of extrahepatic recurrence.
Abstract Cytomegalovirus (CMV) is the most common viral pathogen that negatively affects the outcome of liver transplantation. CMV causes febrile illness often accompanied by bone marrow suppression, ...and in some cases it invades tissues, including the transplanted allograft. In addition, CMV has been significantly associated with an increased predisposition to allograft rejection, accelerated hepatitis C recurrence, and other opportunistic infections, as well as reduced overall patient and allograft survivals. We carried out a study on a Spanish adult liver transplant recipient who rapidly presented anemia and was diagnosed as having Coomb negative (nonimmune) hemolytic anemia, gastric ulcer, pneumonitis, and cholangitis associated with a CMV infection.
Abstract Objectives We sought to evaluate our transplant series in light of the parameters outlined in the quality criteria established by the Spanish Hepatic Transplant Society (Sociedad Española de ...Trasplante Hepático SETH). Methods We retrospectively analyzed 240 hepatic transplantations performed in 223 patients from November 2001 to December 2009. Results Among the series, 57% were in Child class C, 50% had cirrhosis without hepatocellular carcinoma, and 32% had this neoplasm. The most common cause for the illness was alcohol, followed by a virus, namely hepatitis C virus in 76% of cases. The average waiting list time was 45.14 days. The total graft ischemia averaged 460 minutes (range, 265–937). The 4.1% ( n = 10), incidence of an urgent retransplantation was mainly due to primary graft failure or arterial thrombosis. During the perioperative period the mortality rate was 2.5% ( n = 6) and the 1-month mortality rate was 6.6% ( n = 16). The raw survival rates at 1, 3, and 5 years after the operation are 85%, 78%, and 72%, respectively. Conclusion Our perioperative as well as the long-term results fall within the quality standards established by SETH.
Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing ...the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction.
This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index <20), moderate lockdowns (20–60), and full lockdowns (>60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models were used to explore the associations between lockdowns and non-operation. Intervals from diagnosis to surgery were compared across COVID-19 government response index groups. This study was registered at ClinicalTrials.gov, NCT04384926.
Of eligible patients awaiting surgery, 2003 (10·0%) of 20 006 did not receive surgery after a median follow-up of 23 weeks (IQR 16–30), all of whom had a COVID-19-related reason given for non-operation. Light restrictions were associated with a 0·6% non-operation rate (26 of 4521), moderate lockdowns with a 5·5% rate (201 of 3646; adjusted hazard ratio HR 0·81, 95% CI 0·77–0·84; p<0·0001), and full lockdowns with a 15·0% rate (1775 of 11 827; HR 0·51, 0·50–0·53; p<0·0001). In sensitivity analyses, including adjustment for SARS-CoV-2 case notification rates, moderate lockdowns (HR 0·84, 95% CI 0·80–0·88; p<0·001), and full lockdowns (0·57, 0·54–0·60; p<0·001), remained independently associated with non-operation. Surgery beyond 12 weeks from diagnosis in patients without neoadjuvant therapy increased during lockdowns (374 9·1% of 4521 in light restrictions, 317 10·4% of 3646 in moderate lockdowns, 2001 23·8% of 11 827 in full lockdowns), although there were no differences in resectability rates observed with longer delays.
Cancer surgery systems worldwide were fragile to lockdowns, with one in seven patients who were in regions with full lockdowns not undergoing planned surgery and experiencing longer preoperative delays. Although short-term oncological outcomes were not compromised in those selected for surgery, delays and non-operations might lead to long-term reductions in survival. During current and future periods of societal restriction, the resilience of elective surgery systems requires strengthening, which might include protected elective surgical pathways and long-term investment in surge capacity for acute care during public health emergencies to protect elective staff and services.

Liver transplantation (OLT) has been advocated for patients with carcinoma hepatocellular (HCC). A preoperative biopsy (fine needle aspiration biopsy) FNA facilitates preoperative diagnosis of ...adverse pathological factors: vascular invasion or histologicalic differentiation. But a biopsy may cause abdominal dissemination and be related to a higher incidence of recurrence.
From April 1986 to December 2003, we performed 95 OLT for HCC. We divided them in two groups: group A without FNA-biopsy (67.9%) and group B with FNA-biopsy (32.1%).
We obtained the diagnosis of HCC in only 15 patients (57.6%). In two patients an OLT was avoided due to the presence of abdominal dissemination at the time of transplant. Recurrence incidence was higher among group B patients (5.9% vs 31.8%;
P = .003) due to extrahepatic recurrence (2% vs 27.3%;
P = .003). No differences were observed in morbidity or mortality. The two groups were homogeneous in epidemiological and pathological variables except: sex distribution, Child status, AFP level, tumor size, and pTNM stage. If we compare recurrence rates in the two groups attending to these nonhomogeneous variables, it was significantly higher among patients with tumors larger than 3 cm, pTNM I–III stage, Child B-C, AFP >200 ng/mL, and males or females.
Preoperative liver biopsy is associated with a larger incidence of tumor recurrence, so we believe that it is not necessary prior to an OLT for HCC.
