Postoperative tracheal extubation after orthotopic liver transplantation

BACKGROUND: The duration of postoperative mechanical ventilation and its influence on pulmonary function in liver transplant recipients is still debated controversially. METHODS: We retrospectively analyzed the incidence of immediate tracheal extubation, prolonged mechanical ventilation (>24 h following surgery), and episodes of reintubation in 546 patients who underwent orthotopic liver transplantation (OLT) at our institution. RESULTS: Immediate tracheal extubation in the operating theater was achieved in 18.7% of patients, and prolonged mechanical ventilation was required by 11.2% of patients. In these, median time of extubation was 49.5 h, whereas the remaining 70.1% of patients required ventilation support for a median 5 h after OLT. As risk factors for prolonged mechanical ventilation we identified the indications of acute liver failure and retransplantation, as well as factors such as mechanical ventilation prior to OLT, massive intraoperative bleeding, and severe reperfusion injury of the liver graft. The incidence of reintubation was 8.8% in patients who were immediately extubated following surgery, and 13.1% in patients who underwent extubation within 24 h. The incidence was significantly increased in patients requiring prolonged mechanical ventilation (36.1%). CONCLUSIONS: Immediate tracheal extubation was safe and well tolerated. The incidence of reintubation was not increased when compared to patients in whom extubation succeeded later. However, special attention should be given to transplant recipients presenting in reduced clinical condition at the time of OLT, undergoing complicated surgery, or receiving liver allografts with severe reperfusion injury because of an increased risk for prolonged mechanical ventilation.     

七例八次背驮式原位肝移植

对４例Ｗｉｌｓｏｎ病及３例晚期肝病患者施行了８次背驮式原位肝移植术，其中１例为减体积性背驮式原位肝移植。３例已分别存活２年、９个月、６个月，４例死于术后并发症。认为代谢性疾病是原位肝移植的最佳适应证，其次是肝硬变；术后感染、急性和慢性排斥、肺部并发症及胆道并发症是影响患者存活的重要因素；背驮式原位肝移植对全身血流动力学的影响较小。     

Role of Early Extubation in Decreasing Morbidity and Mortality in Liver Transplantation

BackgroundEarly extubation is a fundamental element integrated into enhanced recovery protocols in orthotopic liver transplantation (OLT). The aim is to evaluate whether early extubation influences short- and medium-term postoperative morbidity and mortality.MethodsA cohort of 209 patients who underwent OLT in a tertiary hospital in a period from January 2016 to December 2018 were retrospectively analyzed. Patients were divided into 2 groups: group 1: early extubation in the intensive care unit and group 2: delayed extubation. Mortality is compared between both groups in the first month and first and third year. Postoperative morbidity was also compared.ResultsPatients in group 1 (n = 165, 79.9%) presented, with statistical significance, lower mortality at 1 month, 1 year, and 3 years; shorter duration of admission to the critical care unit and of hospital stay; lower incidence of surgical reoperation and retransplant; lower rate of transfusion of blood products; fewer pulmonary, digestive, neurologic, cardiologic, hemodynamic, kidney, surgical, infectious, metabolic, thrombotic, vascular, and graft complications; less need for kidney replacement therapy; less refractory ascites; and greater infectious risk. However, no statistically significant differences were found in the need for hospital readmission; in biliary, endocrine, nutritional, hematologic, thrombotic, and hematologic complications; or in graft rejection.In group 1, 6.6% of patients required reintubation. In group 2, 97% of patients could be extubated during the first week; 7.8% required noninvasive mechanical ventilation type bilevel positive airway pressure and 8.1% high flow. Only 2.8% of patients required tracheotomy.ConclusionsThe role of early extubation seems key to improve outcomes in OLT because it reduces the incidence of multiple complications and mortality, with low reintubation rates. It is a feasible and safe procedure.     

Long-term outcome of liver resection and transplantation for Caroli disease and syndrome

OBJECTIVE: To assess the preoperative disease characteristics as well as the rate of postoperative complications, patient survival, and course of symptoms after liver resection or orthotopic liver transplantation (OLT) for Caroli disease (CD) or syndrome (CS). SUMMARY BACKGROUND DATA: The clinical course of monolobar or diffuse CD or CS is often characterized by multiple conservative treatment attempts and interventions with recurrent episodes of cholangitis and a serious reduction in quality of life. The role and effectiveness of surgical treatment is still not well defined. PATIENTS AND METHODS: Between June 1989 and December 2002, we treated 44 consecutive patients with CD or CS who had failure of conservative treatment before and were referred for surgical intervention. Demographic and clinical data, operative procedures and related morbidity, course of symptoms, and long-term follow-up were reviewed. Four patients with palliative resection for cholangiocarcinoma and incidental diagnosis of CD were excluded from the analysis. RESULTS: Twenty-two women and 18 men had a median period of 26.5 months from onset of symptoms to surgical therapy. Their median age at therapy was 49 years and 80% of the patients had monolobar disease with a left-right ratio of 2.6 to 1. Thirty-three (82.5%) patients underwent liver resection, while 4 (10%) patients received OLT for diffuse disease. Biliodigestive anastomosis alone was performed in 3 (7.5%) patients with contraindications to OLT. Patients (37.5%) had minor postoperative complications, which were treated conservatively, while 2 (5%) transplanted patients had a reoperation due to intraperitoneal bleeding. After a median follow-up of 86.5 months, we observed a favorable patient and graft survival. Three deaths during follow-up were not related to treatment or disease complications. Follow-up of disease-related symptoms, biliary complications, and antibiotic treatment revealed a significant improvement. CONCLUSION: Our data show that liver resection for monolobar CD or CS and OLT for diffuse manifestations can achieve excellent long-term patient survival with marked symptom relief. Because of life-threatening long-term complications such as biliary sepsis and development of cholangiocarcinoma, timely indication for surgical treatment is crucial.

Liver transplantation in patients with hepatic hydrothorax

Hepatic hydrothorax is a uncommon complication of cirrhotic patients and the results of liver transplantation (OLT) in patients with this complication are not well defined. We studied postoperative complications and survival of 28 patients with hepatic hydrothorax transplanted at our center during a period of 12 years, comparing them with a control group of 56 patients transplanted immediately before and after each case. There were no differences between hydrothorax group and control group in days of mechanical ventilation after surgery, transfusion requirements, postoperative mortality and long-term survival (70% vs. 55% at 8 years, P = 0.11). Long-term evolution was similar between patients with refractory hepatic hydrothorax or spontaneous bacterial empyema and those with noncomplicated hepatic hydrothorax. Hepatic transplantation is an excellent therapeutic option for patients with hepatic hydrothorax. Presence of hepatic hydrothorax does not imply more postoperative complications, and long-term survival is similar to other indications of hepatic cirrhosis.     

Liver transplantation in adults: postoperative management and development during the first months

Recent improvements in the results of orthotopic liver transplantation (OLT) have made this a well-accepted treatment for patients with severe hepatic failure. Current problems encountered following OLT are discussed. Immediate complications comprise surgical bleeding, primary graft non-function, and graft failure due to hepatic artery occlusion. Secondary complications are frequent. Surgical ones include biliary and vascular (hepatic artery thrombosis most often) problems, as well as intra-abdominal abscesses associated with gastrointestinal perforation, biliary leak, graft ischaemia or an infected haematoma. 40% of patients having undergone OLT will be reoperated on, 2/3 of them within 3 months. Non-surgical complications are mostly pulmonary. The risk of pneumonitis is increased by prolonged mechanical ventilation; it is always potentially disastrous in the immunosuppressed, transplanted patient. Hypertension is also often seen in the early postoperative period; it requires prompt treatment. Early renal impairment after OLT is common, and of better prognosis than late onset renal failure, which is generally associated with shock, graft failure, sepsis or use of nephrotoxic agents. Seizures, usually only one, occur in about 10% of patients; recovery is complete. Encephalopathy with intracranial oedema related to fulminant hepatitis has a worse prognosis, but survival figures are quite encouraging. Three type of rejection are described after OLT: 1) severe accelerated rejection (very rare), 2) acute rejection encountered in about 70% of patients over the first 3 months, and 3) late rejection, which can lead to the vanishing bile duct syndrome (VBDS). Diagnosis of rejection is made by liver biopsy. Prophylactic immunosuppression includes cyclosporin, methylprednisolone and azathioprine. Cyclosporin toxicity and drug interactions are reviewed. Treatment of acute rejection episodes comprises an initial bolus of high doses of corticoid drugs; if there is no response, antilymphocyte globulin or monoclonal antibodies may have to be used. Infection is the main cause of death following OLT. Early infections, mostly intra-abdominal and pulmonary, are bacterial or fungal. Vital (especially CMV) and other opportunistic infections occur generally after the second week. Retransplantation, carried out in 10 to 25% of patients, may be urgent in case of primary graft failure, or hepatic artery thrombosis associated with graft failure, or hepatic artery thrombosis associated with graft failure. Other indications are early graft rejection with severe hepatic dysfunction, chronic rejection with severe VBDS, and recurrence of the initial disease.     

Choice of transplantation techniques and indications for liver transplantation in polycystic liver disease in patients with no signs of end-stage liver disease

OBJECTIVE: Since the initiation of the Liver Transplant Program, 500 liver procedures have been performed. Polycystic liver disease (PLD) and polycystic kidney-liver disease (PKLD) have been rare indications for orthotopic liver transplantation (OLT). Only 7 patients (1.4%) underwent transplantation due to PLD and PKLD. MATERIALS AND METHODS: The group consisted of 4 patients who underwent OLT (0.8%) and 3 patients who received simultaneous liver kidney transplantation (LKT; 0.6%). Our objective was to analyze the indications for either OLT or combined LKT as well as indications for surgical techniques during OLT among patients with PLD or PKLD. RESULTS: The main indication for OLT was massive hepatomegaly causing severe physical handicaps, fatigue, and clinically advanced malnutrition. All 3 patients with indications for combined LKT were dialysis-dependent. None of the patients had symptoms of end-stage liver disease and/or hepatic failure. In 4 cases, a portal bypass was applied, and the piggy-back method used in the other 3 cases. The hepatectomy caused no uncommon difficulty. In cases of simultaneous transplantations, the kidney was implanted separately after OLT. All patients are alive following the transplantation; major surgical complications have occurred. CONCLUSIONS: Patients with PLD can undergo OLT safely with good results. They benefit from the relief of abdominal distension and anorexia. Patients with PKLD who are dialysis-dependent should undergo simultaneous LKT. The surgical technique was solely dependent on the intraoperative conditions determined during the dissection phase.     

Incidence and risk factors of development of lung tumors after liver transplantation

INTRODUCTION: Lung tumors have been related to tobacco and alcohol. The incidence increases after orthotopic liver transplantation (OLT) especially when it is performed because of alcoholic cirrhosis. PATIENTS AND METHODS: We analyzed the incidence and risk factors for de novo lung tumors among 701 patients who underwent OLT between April 1986 and July 2004, after exclusion of pediatric recipients and adults who died within 2 months after OLT. RESULTS: The incidence of de novo lung tumors was 15 patients (2.1%), including 12 (4.3%) who underwent OLT for alcoholic cirrhosis and 3 (0.7%) for nonalcoholic diseases. There were 14 men and 1 woman of mean age at OLT of 50.8 +/- 9.6 years. Mean time from OLT to lung tumor was 83 +/- 43 months (range, 10-184 months). Thirteen patients (86.6%) were heavy smokers before OLT and 8 (61.5%) continued after OLT; 12 patients (80%) were heavy drinkers before OLT. Ten patients were immunosuppressed with CyA and 5 with tacrolimus. Acute rejection episodes before tumor diagnosis occurred in 6 patients (40%). Two patients underwent thoracotomy, but only one was resected. The remaining 13 patients were unresectable because of locally advanced tumor or metastatic disease. Two unresectable patients received palliative chemotherapy. All patients died with a mean survival from tumor diagnosis, of 5.3 months (range, 3 days to 33 months). CONCLUSION: A significantly higher incidence of lung tumors was observed among patients who underwent OLT for alcoholic cirrhosis, usually diagnosed in advanced stages of poor prognosis and low survival.     

High incidence of recurrence and hematologic events following liver transplantation for Budd-Chiari syndrome

BACKGROUND: Most cases of Budd-Chiari syndrome (BCS) in Western countries are related to underlying hematologic diseases with inherent thrombogenic propensity. We evaluated the long-term outcome, risks for recurrent disease, and other hematologic complications following orthotopic liver transplantation (OLT) for BCS. METHODS: Clinical data from 11 consecutive patients with BCS who underwent OLT were retrospectively reviewed. Four patients had a prior transjugular intrahepatic portosystemic shunt and one had a surgical shunt procedure. All patients were started on intravenous heparin within the first 24 h following OLT. All except one patient who had protein C deficiency were maintained on long-term oral anticoagulation. RESULTS: The Kaplan-Meier survival rates at 1, 5 and 10 yr were 81, 65 and 65%, respectively. Three patients developed BCS recurrence, including two who died as a consequence of rapid graft failure within days after OLT. Three patients developed other thrombotic events, including splenic vein thrombosis associated with gastric variceal hemorrhage requiring splenectomy, portal vein thrombosis and pulmonary embolism. Four patients experienced severe bleeding complications within 7 d after OLT requiring exploratory laparotomy. One patient died after transformation of polycythemia vera to acute myelogenous leukemia at 2.1 yr after OLT. CONCLUSION: We observed a high incidence of recurrent BCS and complications related to the underlying hematologic disorder or anticoagulation after OLT for BCS. The present series also included the first two cases of rapid recurrence of BCS and graft failure within days after OLT.     

Outcomes after identical and compatible orthotopic liver transplantation for fulminant hepatic failure: a single center experience in UK

To analyze the outcomes between identical and compatible liver transplantation (OLT) for fulminant hepatic failure (FHF) from September 1984 to November 2005. The patients were divided in three groups; group 1 (identical), group 2 (compatible) and group 3 (incompatible), according to the donor-recipient blood type matching. We analyzed several outcomes regarding mortality, patient and graft survival, incidence of acute graft rejection during the first postoperative month (30 days), incidence of biliary complications and indications of re-transplantation. We also analyzed the relationship of Coomb's positive test with postoperative hemolysis to all the above mentioned factors. During the study period, 168 males and 112 females underwent their first OLT for FHF, with 37.1% overall mortality and 42.1% overall graft failure rate. The results between group 1 (203 patients) and group 2 (73 patients) were comparable. A statistically significant difference was recorded in 1 year and overall graft survival between group 1 and group 2 (P = 0.049 and log-rank = 0.035 respectively). Coomb's positive test did not influence the outcomes. OLT in FHF can be safely carried out whether the donor organs are identical or compatible. Hemolysis (Coomb's positive test) after identical or compatible OLT does not influence the outcomes.     

Pulmonary complications following orthotopic liver transplant

Abstract Pulmonary complications after orthotopic liver transplant (OLT) are frequent, involving high morbidity and mortality. We have determined the pulmonary complication incidence in 187 patients submitted to OLT at the General University Hospital "Gregorio Marañón" in the last 4 years, analyzing the type of infection, evolution, diagnostic and therapeutic measures and their influence on OLT mortality. A total of 120 patients had pulmonary complications, the most frequent being pleural effusion (61.94%), pneumonia (43.36%), and pneumothorax (11.5%). Serious pulmonary hypertension was diagnosed by invasive methods in two patients at the time of surgery (unidentified before OLT); both died at early post postoperative times. Pleural effusion was noted in 70 patients, 31.42% of them requiring thoracic tube drainage, complications developing in 22.72 %. Thirteen patients were diagnosed of pneumothorax, the most frequent etiologies being percutaneous liver biopsy, thoracic tube drainage for pleural effusion, and postoperative complications in 41.6, 33.3, and 23.3 %, respectively. Pneumonia was diagnosed in the 1st month after OLT in 45 patients. Tests to diagnose and identify the etiological agent were made in 71.1 % of diagnosed pneumonia patients, identification being obtained in 62.5 %. Telescope catheter culture identified the agent in 48 %, fiber optic bronchoscopy in 50%, and lung or pleural biopsy in 100%. Respiratory insufficiency was noted in 64 patients (34.22 % of transplanted patients). Factors involved in their development were pneumonia (42.18%), graft dysfunction (39.06 %, pleural effusion (34.37 %), sepsis (28.18%), and poor nutritional status (7.81 %). Fifty patients (41.66%) died, pulmonary pathology being the determinant factor in 28.8%. Patient mortality with respiratory insufficiency was greater, especially in those with three factors involved the development of respiratory insufficiency.     

Long-term results of orthotopic liver transplantation during the cyclosporin era. 393 orthotopic liver transplantations accomplished in 313 consecutive patients at the Pittsburgh Transplantation Center

During the cyclosporine era 1980-1984, 393 consecutive orthotopic liver transplantations (OLT) were performed in 313 patients at the University of Pittsburgh. This paper analyses the long-term results in this group of patients who have been followed-up for a minimum of three years. The results of OLT for different indications are discussed. The five-year survival rates after OLT for metabolic diseases, biliary atresia, primary biliary cirrhosis, posthepatic cirrhosis and primary hepatobiliary cancer are 75%, 68%, 60%, 58.9%, 53.2% and 23.8%, respectively. Recurrence of the primary disease after OLT is rare for benign diseases but rather frequent for malignant ones. The incidence of retransplantation for delayed rejection and for extrahepatic complications is discussed. The quality of life for most of the long-term survivors is good. Because of its good long-term results, OLT should become the therapy of choice in a lot of acute and chronic hepatopathies.     

Auxiliary Partial Orthotopic Versus Standard Orthotopic Whole Liver Transplantation for Acute Liver Failure: A Reappraisal From a Single Center by a Case-Control Study

OBJECTIVE: To reappraise the results of auxiliary partial orthotopic liver transplantation (APOLT) compared with those of standard whole-liver transplantation (OLT) in terms of postoperative death and complications, including neurologic sequelae. SUMMARY BACKGROUND DATA: Compared with OLT, APOLT preserves the possibility for the native liver to recover, and to stop immunosuppression. METHODS: In a consecutive series of 49 patients transplanted for fulminant or subfulminant hepatitis, 37 received OLT and 12 received APOLT. APOLT was done when logistics allowed simultaneous performance of graft preparation and the native liver partial hepatectomy to revascularize the graft as soon as possible. Each patient undergoing APOLT (12 patients) was matched to two patients undergoing OLT (24 patients) according to age, grade of coma, etiology, and fulminant or subfulminant type of hepatitis. All grafts in the study population were retrieved from optimal donors. RESULTS: Before surgery, both groups were comparable in all aspects. In-hospital death occurred in 4 of 12 patients undergoing APOLT compared with 6 of 24 patients undergoing OLT. Patients receiving APOLT had 1 +/- 1.3 technical complications compared with 0.3 +/- 0.5 for OLT patients. Bacteriemia was significantly more frequent after APOLT than after OLT. The need for retransplantation was significantly higher in the APOLT patients (3/12 vs. 0/24). Brain death from brain edema or neurologic sequelae was significantly more frequent after APOLT (4/12 vs. 2/24). One-year patient survival was comparable in both groups (66% vs. 66%), and there was a trend toward lower 1-year retransplantation-free survival rates in the APOLT group (39% vs. 66%). Only 2 of 12 (17%) patients had full success with APOLT (i.e., patient survival, liver regeneration, withdrawal of immunosuppression, and graft removal). One of these two patients had neurologic sequelae. CONCLUSIONS: Using optimal grafts, APOLT and OLT have similar patient survival rates. However, the complication rate is higher with APOLT. On an intent-to-treat basis, the efficacy of the APOLT procedure is low. This analysis suggests that the indications for an APOLT procedure should be reconsidered in the light of the risks of technical complications and neurologic sequelae.     

Long-term results after liver transplantation.

Liver transplantation (OLT) has become a successful surgical therapy for terminal liver failure. We here report about long-term results of OLT in a single center over a period of 15 years. Between 1988 and 2002, 1365 adult OLTs were performed. Mean follow-up was 103 +/- 56 months. Main indications for OLT were viral-induced cirrhosis (27.1%), alcoholic liver disease (21%), tumors (15.7%) and cholestatic liver disease (14.6%). Retransplantation was necessary in 120 (9.6%) patients because of initial nonfunction (26.9%), recurrence of underlying disease (20.2%), acute and chronic rejection (16.8%) or thrombosis of the hepatic artery (16.8%). 275 patients (22.1%) died. Causes of death included recurrence of disease (32.1%), infections (21.8%), de novo malignancies (13.5%) and cardiovascular disease (11.6%). Patient survival after OLT was 91.4%, 82.5%, 74.7% and 68.2% after 1, 5, 10 and 15 years, and graft survival was 85.8%, 75.3%, 67.3% and 61.7% after 1, 5, 10 and 15 years, respectively. Patient survival after retransplantation was 81.6%, 68.8% and 57.1% and 48.0% after 1, 5, 10 and 15 years. This analysis reveals excellent long-term results after OLT achieved in a single center.     

Red blood cell transfusion in liver transplantation: a case-control study

INTRODUCTION: We aimed to analyze the influence of intraoperative blood transfusion on postoperative complications and survival and to identify the preoperative variables associated with greater intraoperative bleeding. MATERIALS AND METHODS: Thirty-one elective liver transplantations (OLT) without blood transfusion performed between 1986 and 2002 (group 1) were compared with 62 patients (group 2) who underwent elective OLT with intraoperative transfusion after matching for gender, disease severity, and chronology. RESULTS: The hemoglobin and hematocrit values were significantly greater in group 1 compared to group 2. No significant differences were reported for the other parameters. In particular, the type of surgical technique had no influence on the blood requirement. As expected the nontransfused patients received less autologous packed red blood cells compared with the transfused patients. No differences were observed in either group for mean CIT, ICU and hospital stay, or acute rejection. A significant difference was observed in the number of postoperative infectious episodes, which was higher in group 2 (28 vs 5, P = .01). Graft and patient survivals at 3 months and 5 years did not differ significantly between groups. CONCLUSIONS: OLT without blood transfusion may be achieved in the presence of good recipient conditions. Lower preoperative hemoglobin and hematocrit values were associated with greater intraoperative transfusions.     

Liver transplantation for alcoholic cirrhosis with anti-HCV antibodies

The results of orthotopic liver transplantation (OLT) in patients with alcoholic liver cirrhosis (ALC) are currently similar to those obtained in patients with other indications. However, the frequent association of ALC with hepatitis C virus (HCV) infection may impair these results. We retrospectively studied the consequences of HCV infection on survival and graft function in 59 patients with ALC undergoing OLT. Patients were classified into two groups depending on their HCV serology before transplantation: group 1 comprised 24 anti-HCV-positive patients, and group 2, 35 anti-HCV-negative patients. Patient and graft survival were similar in both groups. Liver function tests 1 and 4 years after OLT showed AST and ALT values that were significantly higher in group 1 patients and post-transplant histologically proven chronic hepatitis was found in 45 % and 61 % of these patients at 1 and 4 years, respectively. We conclude that pretransplant HCV infection in patients with ALC does not affect survival after OLT. However, one must bear in mind the high incidence of post-transplant chronic hepatitis secondary to recurrence of HCV infection and be cautious when drawing this conclusion.

Analysis of long-term outcomes of 3200 liver transplantations over two decades: a single-center experience

OBJECTIVE: Few studies have evaluated long-term outcomes after orthotopic liver transplantation (OLT). This work analyzes the experience of nearly 2 decades by the same team in a single center. Outcomes of OLT and factors affecting survival were analyzed. METHODS: Retrospective analysis of 3200 consecutive OLTs that were performed at our institution, between February 1984 and December 31, 2001. RESULTS: Of 2662 recipients, 578 (21.7%) and 659 (24.7%) were pediatric and urgent patients, respectively. Overall 1-, 5-, 10-, and 15-year patient and graft survival estimates were 81%, 72%, 68%, 64% and 73%, 64%, 59%, 55%, respectively. Patient survival significantly improved in the second (1992-2001) versus the era I (1984-1991) of transplantation (P < 0.001). Similarly, graft survival was better in the era II of transplantation (P < 0.02). However, biliary and infectious complications increased in era II. When OLT indications were considered, best recipient survival was obtained in children with biliary atresia (82%, 79%, and 78% at 1, 5, and 10 years, respectively), while malignant disease in adult patients resulted in the worst outcomes of 68% and 43% at 1 and 5 years, post-OLT. Further, patients <18 years and nonurgent recipients exhibited superior survival when compared with recipients >18 years (P < 0.001) or urgent patients (P < 0.001). Of 13 donor and recipient variables, era of OLT, recipient age, urgent status, donor age, donor length of hospital stay, etiology of liver disease, retransplantation, warm and cold ischemia, but not graft type (whole, split, living-donor), significantly impacted patient survival. CONCLUSIONS: Long-term benefits of OLT are greatest in pediatric and nonurgent patients. Multiple factors involving the recipient, etiology of liver disease, donor characteristics, operative variables, and surgical experience influence long-term survival outcomes. By balancing and matching these factors with a given recipient, optimum results can be achieved.     

First-line liver resection and salvage liver transplantation are increasing therapeutic strategies for patients with hepatocellular carcinoma and child a cirrhosis

AIM: The present study focused on nine patients with hepatocellular carcinoma (HCC) associated with Child A liver cirrhosis undergoing first-line liver resection and salvage liver transplantation (SLT) for liver tumor recurrence. PATIENTS AND METHODS: Forty-six patients with HCC underwent liver transplantation (OLT); 37 (80.5%) were primary liver transplantations (PLTs) and 9 (19.5%) were SLTs. All patients who underwent SLT received minor transabdominal liver resections. RESULTS: The posttransplant 1-, 3-, and 5-year overall survival rates for SLT (88.9%, 88.9%, and 88.9%) were similar to those for PLT (78%, 62.7%, and 62.7%). Four (10.8%) patients in the PLT group had HCC recurrence, while there was zero recurrence in the SLT group. The 1-, 3-, 5-year disease-free survival rates for PLT (89%, 74%, and 74%) were similar to those for SLT (100%, 100%, and 100%). The 1-, 3-, 5-year disease-free survival rates after PLT were 89%, 74%, and 74%, and after SLT were 100%, 100%, and 100%, respectively. The operative mortality, intraperioperative bleeding, operative time, intensive care unit stay, in-hospital stay, and overall incidence of postoperative complications were similar in the two groups. CONCLUSIONS: In our experience, SLT for HCC is a feasible procedure with similar results in terms of overall survival, disease-free survival, and postoperative complications to those reported for patients who underwent PLT at our institute. An important role exists for SLT as shown by the fact that such a strategy has been used in the 20% of the patients undergoing OLT for HCC.     

Liver transplantation in Wilson's disease: are its indications established?

The indications of progressive neurological deterioration despite no hepatic insufficiency, for liver transplant (OLT) in patients with Wilson's disease (WD) who do not improve with medical treatment is widely debated. The aim of this paper was to present our OLT experience in WD. PATIENTS AND METHODS: Fourteen patients were given a transplant after the diagnosis of WD for the following indications: in four patients, a steady neurological deterioration that failed to respond to chelation treatment (all with Child grade A liver function); in nine patients, Child grade C hepatic insufficiency, in whom medical treatment had failed (one of these patients also presented with severe neurological alterations); and in one patient, acute hepatic failure secondary to E. Coli infection of the ascitic fluid. RESULTS: Two patients died, one due to severe pancreatitis in the immediate postoperative period and the other, who was transplanted for neurological involvement, experienced an acute rejection episode treated with methylprednisolone in the first postoperative month and, in the 4th month, another episode of acute rejection, failed to respond to corticoids and required OKT-3 administration. She subsequently developed bilateral bronchopneumonia due to cytomegalovirus that led to her death. During the immediate postoperative period all of the cupremia, cupriuria, and ceruloplasmin levels returned to normal. The liver function in the 12 patients currently alive was totally normal after a follow-up of 8 years (range, 1-15 years) with actuarial 5-year survival of 85.7%. CONCLUSIONS: These cases demonstrated that OLT may mobilize copper sufficiently from the central nervous system to correct severe neurological deficits, a result that medical therapy alone cannot achieve. We suggest that OLT be considered for patients with WD who have crippling neurological and psychological diseases, even if liver function is stable.
