Outcome of HCV/HIV-coinfected liver transplant recipients: a prospective and multicenter cohort study.

Eighty-four HCV/HIV-coinfected and 252-matched HCV-monoinfected liver transplant recipients were included in a prospective multicenter study. Thirty-six (43%) HCV/HIV-coinfected and 75 (30%) HCV-monoinfected patients died, with a survival rate at 5 years of 54% (95% CI, 42-64) and 71% (95% CI, 66 to 77; p = 0.008), respectively. When both groups were considered together, HIV infection was an independent predictor of mortality (HR, 2.202; 95% CI, 1.420-3.413 [p < 0.001]). Multivariate analysis of only the HCV/HIV-coinfected recipients, revealed HCV genotype 1 (HR, 2.98; 95% CI, 1.32-6.76), donor risk index (HR, 9.48; 95% CI, 2.75-32.73) and negative plasma HCV RNA (HR, 0.14; 95% CI, 0.03-0.62) to be associated with mortality. When this analysis was restricted to pretransplant variables, we identified three independent factors (HCV genotype 1, pretransplant MELD score and centers with <1 liver transplantation/year in HIV-infected patients) that allowed us to identify a subset of 60 (71%) patients with a similar 5-year prognosis (69%[95% CI, 54-80]) to that of HCV-monoinfected recipients. In conclusion, 5-year survival in HCV/HIV-coinfected liver recipients was lower than in HCV-monoinfected recipients, although an important subset with a favorable prognosis was identified in the former.

Disseminated adiaspiromycosis: case report of a liver transplant patient with human immunodeficiency infection, and literature review.

Disseminated adiaspiromycosis is a rare infection that is sometimes associated with immunocompromised situations. We report the case of a patient, infected with human immunodeficiency virus and receiving highly active antiretroviral therapy, who had a liver transplant for hepatocellular carcinoma. The patient presented skin and pulmonary lesions due to adiaspiromycosis during immunosuppressive therapy. A review of >60 cases in the literature shows that adiaspiromycosis is a rare infection and Emmonsia is a dimorphic fungus that is difficult to grow. It should be considered a possible diagnosis in case of fungal infection and pulmonary granulomatosis. We should be aware of emerging adiaspiromycosis in patients with risk factors of immunosuppression, particularly transplant recipients. In these patients in particular, liposomal amphotericin B therapy should be considered.

Preoperative gastric conditioning in cervical gastroplasty.

To determine if ischemic conditioning of the stomach improves the morbidity, mortality, and the anastomotic failure in gastroplasties with cervical anastomosis. Analysis of all patients with indication for cervical gastroplasty during the period of study. In all cases, ischemic conditioning was performed by selective embolization. Anastomotic failure, morbidity, and mortality rates were studied. Thirty-nine consecutive patients were included. Angiography and selective embolization of the left gastric, right gastric, and splenic arteries were performed. Surgery was performed 2 weeks later. Four patients did not have a complete embolization; median hospital stay after conditioning was 1.24 ± 0.6 days. In two patients, surgery could not be completed. Of the 33 remaining, 29 had a posterior mediastinic gastroplasty and four through the anterior mediastinum. The most common morbidity was respiratory. Five patients had a reoperation and the mortality was 6%. One case of anastomotic leak was found (3%). The mean hospital stay was 17.5 days. Preoperative embolization is a technique with acceptable morbidity and a short hospital stay. In our experience it can reduce the incidence of the morbidity, mortality, and anastomotic leak in gastroplasties with cervical anastomosis. Prospective studies will be necessary to demonstrate the validity of this approach.

Antral mass due to cytomegalovirus infection requiring gastrectomy in a liver transplant recipient.

The incidence of cytomegalovirus (CMV) infection after liver transplantation (LT) has decreased in recent years. Advances in immunosuppression and CMV prophylaxis have improved the management of CMV disease. Organ involvement is infrequent and gastrointestinal CMV disease is quite rare. Few cases of an antral mass due to CMV infection have been described; those reported to date have mostly been in patients with acquired immunodeficiency syndrome. We describe a case of a CMV-seronegative liver transplant patient who received a seropositive liver graft. Owing to gastrointestinal complaints, CMV prophylaxis was stopped one month after LT. The patient developed an antral mass due to CMV infection and an anastomotic biliary stricture. Antigenemia became negative with ganciclovir, but this treatment did not eliminate the mass. Ganciclovir resistance was ruled out as well as other causes of antral mass, especially malignancy. The patient finally required gastrectomy and hepaticojejunostomy. We conclude that CMV disease is less common today but should be included in the diagnosis of gastrointestinal mass after transplantation.

Efficacy of enteral decontamination in the prevention of anastomotic dehiscence and pulmonary infection in esophagogastric surgery.

Our aim in this study is to evaluate the efficacy of decontamination of the high digestive tract in reducing the incidence of anastomotic dehiscence, pulmonary infection and mortality after resective gastro-esophageal surgery. A prospective randomized and double-blinded study was conducted in patients undergoing total gastrectomy for gastric cancer and esophagectomy for esophageal cancer. Two groups were studied: group A patients were given erythromycin + gentamicine + nistatine sulfate orally; group B patients were given placebo. Mortality, incidence of anastomotic dehiscence and incidence of pulmonary infection were the end points evaluated. One hundred and nine consecutive patients were randomized. Eighteen (16.5%) were excluded. From the 91 patients who were evaluated, 42 (46.2%) received an esophagectomy and 49 (53.8%) had a total gastrectomy. Esophagectomies showed: a 0% rate of anastomotic dehiscence in group A and 12.5% in group B, P = 0.176; a pulmonary infection rate of 22.2% in group A and 29.1% in group B, P = 0.443; and mortality rate was 0% in group A and 12.5% in group B, P = 0.176. After gastrectomy, anastomotic dehiscence rate was 4.5% in group A and 0% in group B, P = 0.449; pulmonary infection rate was 4.5% in group A and 11.1% in group B, P = 0.387 and mortality was 9% in group A and 0% in group B, P = 0.196. Decontamination protocol does not help in decreasing the incidence of anastomotic dehiscence, pulmonary infection and mortality in the present study. Nevertheless, there seems to be a tendency to low pulmonary infection after gastrectomy and esophagectomy and to improve the incidence of anastomotic dehiscence after esophagectomy. Further studies are needed to re-evaluate these findings.

Time course of necrosis/apoptosis and neovascularization during experimental gastric conditioning.

Apoptosis, necrosis and neovascularization are three processes that occur during ischemic preconditioning in a range of organs. In the stomach, the effect of this preconditioning (the delay phenomenon) has helped to improve gastric vascularization prior to esophagogastric anastomosis after esophagectomy. Here we present a sequential study of the histological recovery of the gastric fundus and the phenomena of apoptosis, necrosis and neovascularization in an experimental model of partial gastric ischemia. Partial gastric devascularization was performed by ligature of the left gastric vessels in Sprague-Dawley rats. Rats were assigned to groups in accordance with their evaluation period: control, 1, 3, 6, 10, 15 and 21 days. Histological analysis, caspase-3 activity, DNA fragmentation and vascular endothelial cell proliferation (Ki-67) were measured in tissue samples after sacrifice. After 24 h of partial gastric ischemia, rates of apoptosis and necrosis were higher in the experimental groups than in controls. Tissue injury was higher 3 and 6 days post-ischemia. From day 10 after partial gastric ischemia, apoptosis and necrosis started to decrease, and on days 15 and 21 showed no differences in relation to controls. Neovascularization began between days 1 and 3, reaching its peak at 15 days after ischemia and coinciding with complete histological recovery. Both necrosis and apoptosis play a role in tissue injury during the first days after partial gastric ischemia. After 15 days, the evolution of both the histology and the neovascularization suggested that this is the optimal time for performing gastric transposition.

Surgical treatment of liver metastases from colorectal carcinoma in elderly patients. When is it worthwhile?

BACKGROUND: The elderly are under-represented in series of patients operated on for colorectal liver metastases (LM). OBJECTIVE: To analyse the influence of age on surgery of colorectal LM, and the identification of factors that could be used as exclusion criteria. PATIENTS AND METHODS: Six hundred and forty-eight patients underwent liver resection between 1990 and 2006. Demographic data, primary tumour related variables, stage of the disease, morbidity, mortality, survival and recurrence were prospectively recorded. RESULTS: One hundred and sixty of 648 patients (25%) were 70 years old or older. Postoperative mortality was significantly higher in elderly patients (8% vs. 3%, p=0.008). Morbidity was also higher (41% vs. 34%, p=0.008). Survival rate at 1, 3 and 5 years was 88%, 62% and 45% respectively in patients younger than 70 years, and 82%, 48% and 36% in the elderly (p=0.007). Excluding the postoperative mortality, the figures were 90%, 64% and 46%. 90%, 53% and 38% (p=0.061). Disease-free survival rates at 1, 3 and 5 years excluding postoperative mortality were 68%, 32% and 25% in younger patients, compared to 68%, 34% and 30% (p=0.71) in the elderly. Major liver resections increased mortality in the elderly. In the multivariate analyses only a tumour size equal to or more than 10 cm significantly increased the postoperative mortality risk in elderly patients. CONCLUSIONS: The elderly have a higher mortality. In recent years that difference has been markedly reduced. Excluding the postoperative mortality, the overall survival and disease-free survival are similar between both groups. The criteria to indicate surgery must be the same in both groups.

[Factors related to renal dysfunction after liver transplantation in patients with normal preoperative function]. / Factores relacionados con la disfunción renal postoperatoria en pacientes trasplantados hepáticos con función preoperatoria normal.

OBJECTIVE: To determine perioperative factors related to postoperative renal dysfunction in patients receiving liver transplants who had normal renal function before surgery. PATIENTS AND METHODS: We analyzed the cases of 189 consecutive patients. Patients with hepatorenal syndrome and previously diagnosed renal insufficiency were excluded, as were patients undergoing a second transplant operation. Postoperative renal dysfunction was diagnosed when creatinine levels exceeded 1.5 mg x dL(-1) in the first postoperative week. Multivariate analysis of preoperative variables (patient characteristics; Child-Pugh score; status with the United Network for Organ Sharing; and sodium, coagulation, hemoglobin, and creatinine levels); intraoperative variables (blood product units required, duration of surgery, reperfusion syndrome, surgical technique, and crystalloids required); and postoperative variables (hemodialysis or filtration, reoperation, mortality, creatinine levels at 6 and 12 months). RESULTS: One hundred fifty patients with normal kidney function were included. Postoperative renal dysfunction developed in 45 (30%). Differences between patients with and without postoperative renal dysfunction were found for weight; sex; Child-Pugh score; blood transfusion requirements (mean [SD] of 2.36 [2.4] units of packed red cells in the group of patients with renal dysfunction vs 1.3 [1.8] in the patients with normal function); and reperfusion syndrome (26 [66.7%] patients with renal dysfunction and 35 [21.5%] without). The last 2 variables continued to be significantly correlated with renal dysfunction in the multivariate analysis with a relative risk of 1.25, (95% confidence interval [CI], 1.01-1.55) for units of blood transfusion and 2.41 (95% CI, 1.04-5.57) for reperfusion syndrome. Renal replacement therapy was used in 4 patients (2.7%). Mortality rates were similar. At 6 and 12 months, 26 (17.3%) and 18 (12%) patients had renal dysfunction. CONCLUSIONS: Acute renal dysfunction is a frequent complication following a liver transplant and it is associated with transfusion of more units of blood products even when the average transfusion amount is not large.

The anterior hanging-approach improves postoperative course after right hepatectomy in patients with colorectal liver metastases. Results of a prospective study with propensity-score matching comparison.

PURPOSE: To establish the role of the anterior approach with liver hanging maneuver for right hepatectomy in patients with colorectal liver metastases (CRLM). SUMMARY BACKGROUND DATA: The indications for hepatectomy in patients with CRLM are expanding. The liver remnant must be protected to avoid morbidity. METHODS: We prospectively enrolled all patients with the diagnosis of CRLM requiring right hepatectomy from 2009 to 2012. In all cases right hepatectomy with an anterior-hanging maneuver approach was attempted. We compared the group of patients who underwent this procedure with a group of patients who had previously undergone a conventional right hepatectomy. To minimize selection bias, propensity score matching was performed, based on baseline patient characteristics. RESULTS: A right hepatectomy was planned in 57 cases. The anterior-hanging approach was feasible in 85% of cases. Overall morbidity was similar. In-hospital mortality due to hepatic insufficiency was 2.3% in anterior-hanging group compared to 9% in the conventional group (p = 0.30). The incidence of ascites was significantly greater in the conventional group (AH: 18% vs Conv: 54%; p = 0.002), and hospital stay was longer (AH: 10.9 ± 5.7 vs Conv: 14.4 ± 8.1 days; p = 0.05). Bilirubin levels were significantly lower in anterior-hanging group in day 1 and 3. There were no differences on recurrence nor survival. CONCLUSIONS: The anterior-hanging approach for right hepatectomy in patients with CRLM can be used safely with a high feasibility rate. Its use contributes to improve postoperative course.

Safety and Efficacy of Ultrasound-Guided Radiofrequency Ablation of Recurrent Colorectal Cancer Liver Metastases after Hepatectomy.

INTRODUCTION: To assess the results and outcome of radiofrequency ablation in the treatment of recurrent colorectal liver metastases. PATIENTS AND METHODS: Between January 2005 and September 2012, we treated 59 patients with recurrent colorectal metastases not amenable to surgery with 77 radiofrequency ablation procedures. Radiofrequency was indicated if oncologic resection was technically not possible or the patient was not fit for major surgery. A total of 91 lesions were treated. The mean number of liver tumors per patient was 1.5, and the mean tumor diameter was 2.3 cm. In 37.5% of the cases, lesions had a subcapsular location, and 34% were close to a vascular structure. RESULTS: The morbidity rate was 18.7%, and there were no post-procedural deaths. Distant extrahepatic recurrence appeared in 50% of the patients. Local recurrence at the site of ablation appeared in 18% of the lesions. Local recurrence rate was 6% in lesions less than 3 cm and 52% in lesions larger than 3 cm. The size of the lesions (more than 3 cm) was an independent risk factor for local recurrence (p < 0.05). Survival rates at 1, 3, and 5 years were 94.5%, 65.3%, and 21.7%, respectively. DISCUSSION: Radiofrequency ablation is a safe procedure and allows local tumor control in lesions less than 30 mm (local recurrence of 6%) and provides survival benefits in patients with recurrent colorectal liver metastases.

The impact of donor age on liver transplantation: influence of donor age on early liver function and on subsequent patient and graft survival.

BACKGROUND: The urgent need to increase the organ donor pool has led to the expansion of criteria for donor selection. The aim of this study was to analyze the influence of donor age on early graft function, subsequent graft loss, and mortality after liver transplantation (LT). METHODS: Data on LT were evaluated retrospectively in a population-based cohort of 400 LTs in 348 patients. Of these, 21 (5%) were from donors >70 years old. Pretransplantation donor and recipient characteristics and the evolution of recipients were analyzed. The influence of donor age as a risk factor was assessed using univariate and multivariate analyses. RESULTS: Actuarial graft survival was 89% at 1 month after LT, 81% after 6 months, and 59% after 60 months. Multivariate analysis demonstrated that only donor age (>70 years old) was associated with a higher risk of long-term graft loss (relative risk [RR]=1.4, 95% confidence interval [CI]=1-1.9; P=0.03) and mortality (RR=1.7, 95% CI=1.2-2.3; P=0.01). Graft survival of septuagenarian livers was 80% at 1 month after LT, 56% after 6 months, and 25% after 54 months. Actuarial survival analysis (Kaplan-Meier curves) also demonstrated worse evolution in recipients of livers from old donors (log-rank test, P<0.001). CONCLUSIONS: Advanced donor age is associated with lower graft and recipient survival.

Results of using the recipient's splenic artery for arterial reconstruction in liver transplantation in 23 patients.

BACKGROUND: Arterial reconstruction is essential in liver transplantation. In some patients there may be an inadequate flow as a result of stenosis, intimal dissection, or anomalies of the hepatic artery. METHODS: This study analyzes our experience with 23 patients in whom arterial anastomosis was performed using the splenic artery due to the inadequacy of the hepatic artery. During the same period an aortoiliac conduit was used in 12 liver transplantations due to the same problem. RESULTS: No splenic infarction, pancreatitis, or other related complications were found. Artery thrombosis developed in only two patients in the aortoiliac conduit group. One- and three-year patient actuarial survival were 78% vs. 80% and 72% vs. 80%, respectively, for the splenic artery group and the aortoiliac conduit group. CONCLUSIONS: Anastomosis with the splenic artery is an alternative in liver transplantation and is particularly suitable when splenomegaly is present.

Resection or transplantation for hepatocellular carcinoma in cirrhotic patients: outcomes based on indicated treatment strategy.

BACKGROUND: Surgical resection has been the treatment of choice for hepatocellular carcinoma (HCC), but the resection rate remains low in cirrhotic patients and recurrence is common. Unfavorable results compared with benign disease and the shortage of organ donors have led to a restricted indication for orthotopic liver transplantation (OLT) for HCC. STUDY DESIGN: The aim of this study was to analyze the results of our surgical approach to HCC in patients with cirrhosis. The first treatment strategy indicated in these patients was OLT. From January 1990 to May 1999, 85 patients underwent OLT and the remaining 35 had surgical resection. RESULTS: One-, 3-, and 5-year survival rates were 84%, 74%, and 60% versus 83%, 57%, and 51%, respectively, in the OLT and resection groups (p = 0.34). Hepatic tumor recurrence was much less frequent in the OLT group than in the resection group. The 1-, 3-, and 5-year disease-free survival rates were 83%, 72%, and 60% versus 70%, 44%, and 31%, respectively (p = 0.027). In the multivariate Cox regression analysis, macroscopic vascular invasion was the only factor independently associated with death or recurrence after OLT (p = 0.006). After partial liver resection, the tumors significantly associated with mortality and recurrence in the multivariate analysis were solitary or multiple tumors greater than 2cm with microscopic vascular invasion (pathologic pT3) (p = 0.01). CONCLUSIONS: Our results confirm that in cirrhotic patients, OLT may provide better outcomes than liver resection in carefully selected HCC and that longterm survival is similar to the results of OLT in cirrhotic patients without tumors.

Successful diagnosis and treatment of cardiac perforation due to subclavian catheter during total parenteral nutrition.

A case of atrial perforation by a subclavian vein catheter, which was inserted for total parenteral nutrition (TPN) is reported. Acute thoracic symptoms developed 3 days after the infusion was started. The diagnosis was correctly made by demonstrating contrast medium within the pericardial sac. The catheter was withdrawn and the patient recovered satisfactorily. The clinical picture and the differential diagnosis of this complication are discussed.

[Prognostic factors of thyroid function following surgical therapy in Graves-Basedow's disease]. / Factores pronósticos en el resultado funcional del tratamiento quirúrgico de la enfermedad de Graves-Basedow.

BACKGROUND: The goals of this work are to describe late thyroid function and to determine predictive factors of permanent hypothyroidism following surgery in Graves-Basedow's disease. PATIENTS AND METHOD: From 1979 to 1999, 107 patients with hyperthyroidism due to Graves-Basedow's disease underwent subtotal thyroidectomy. We performed life-table analysis and calculated the cumulative incidence of hypothyroidism by means of the Kaplan-Meier's method. Survival (euthyroidism)within patients groups was compared using the Mantel-Cox method. Variables influencing long-term thyroid function were determined by estimating the Odds ratio with a logistic regression model. RESULTS: The probability of euthyroidism among all 107 patients at 240 months was 51.4%.Age, gender, duration of both hyperthyroidism and antithyroid therapy and weight of resected thyroid tissue did not influence the eventual outcome. The weight of thyroid remnant was 5.4 (1.5)g and the conditional logistic regression analysis showed that weight of thyroid remnant was the only variable influencing long-term thyroid function. Hyperthyroidism relapsed in 5 patients. CONCLUSIONS: In our experience,surgery represents a definitive alternative treatment with a risk of hypothyroidism within the first 2 years of 43.9%. The weight of thyroid remnant is the only variable influencing long-term thyroid function.

[Clinical study of 437 consecutive hepatectomies]. / Estudio clínico de 437 hepatectomías consecutivas.

BACKGROUND: The aim of this prospective study was to analyze the risk of liver resection in unselected patients. PATIENTS AND METHOD: From 1990 to 2000, 437 consecutive hepatectomies were performed in our center. Most frequent indications were liver metastases (n = 288), hepatocellular carcinoma (n = 62), Klatskin tumor (n = 17), gallblader carcinoma (n = 139) and other malignant tumors (n = 6). The indication was a benign tumor in 51 patients. In 357 cases the liver parenchyma was normal, 51 patients had an underlying cirrhosis and 17 patients had an obstructive jaundice. RESULTS: Overall mortality was 3.6% (15 cases). Mortality in benign tumors was lacking. The prevalence of postoperative complications was 43.9%, which was mainly influenced by malignancy (46.9% vs 21.6%, p = 0.001) and type of tumor (Klastkin tumor, p # 0.001). Major liver resection (p < 0.001), blood transfusion (p < 0.001), age over 60 years (p = 0.001) and the type of hepatectomy (p < 0.001) also increased significantly the morbidity. The prevalence of biliary fistula was 11.2%, which was mainly related to the type of hepatectomy (major hepatectomy; p = 0.002) and a biliary-enteric anastomosis (p < 0.001). The prevalence of hepatic insufficiency was 3.6%, and chief risk factors for its development were underlying liver disease and major liver resection (p = 0.017). CONCLUSIONS: Mortality after hepatectomy in experienced centers is low. Morbidity is mainly related to the amount of parenchyma resected, type of hepatectomy, underlying liver disease and associated procedures. Liver resection should be performed preferentially in centers with high volume by specialized surgeons.

[Quality of life after liver transplant]. / Calidad de vida tras el trasplante hepático.

Hepatic transplant has recently undergone ostensible changes in post operative mortality. The present study investigates whether this improvement in survival is associated with a subjective and objective improvement in quality of life. Nineteen patients were evaluated preoperatively and/or postoperatively with a questionnaire (Nottingham Health Profile). The results showed a remarkable improvement in the quality of life of these patients, which became more marked after three months. The readaptation to work was good, considering the current state of our society. The mean yearly hospital stay was 12 days, distributed in three admissions mainly to perform hepatic biopsy.

[Sequential liver transplantation: description of the first three patients in Spain]. / Trasplante hepático dominó o secuencial: descripción de los tres primeros pacientes en España.

BACKGROUND: Domino or sequential liver transplantation (DTXL) is a kind of living donor transplant, which was proposed in 1993 and performed for the first time in 1995; later on, more than 45 have been reported. The liver from a patient with familial amyloidotic polyneuropathy(FAP) is used to another patient aged more than 60 with hepatic disease generally cancer, because FAP livers are anatomically and functionally normal except for the synthesis of the systemic TTR variant which only could generate FAP in the recipient after more than 8 years. PATIENTS AND METHOD: The three first cases of DTXL performed in Spain are presented. The donors were FAPTTRMet30 patients from the Major can focus. The first recipient showed severe hyperinsulinism due to metastatic liver from malignant insulinoma; the others had hepatocellular carcinoma on a cirrhotic liver. RESULTS: During the post operatory period liver function of recipients was perfect,and hyperinsulinism disappeared in the first; this patient died after 10 days by sepsis whereas the others showed normal liver function, no recurrent cancer nor onset of FAP. The donors outcome was normal with perfect liver function. CONCLUSIONS: Based on our results, in agreement with previous reports, we conclude that DTXH is valid procedure for a selected patient group. In addition they increase the pool of liver donors and therefore diminish the overloaded waiting lists.

[Usefulness of the genetic study in the diagnosis of medullary carcinoma of the thyroid]. / Utilidad del estudio genético en el diagnóstico del carcinoma medular de tiroides.

Germ-line mutations in the RET proto-oncogene are associated with multiple endocrine neoplasia type 2A (MEN 2A) and with familial medullary thyroid carcinoma (FMTC). Detection of these mutations allows the identification of the affected kindred members, who will develop medullary thyroid carcinoma (MTC) in 100% of cases. We studied 24 patients of two kindreds (MEN 2A and FMTC). Basal calcitonin levels and pentagastrin-stimulated calcitonin were measured in all patients. The RET mutations were detected by DNA analysis. The RET mutations were identified in 14 patients. Two of them had been operated in the past, 2 refused operation and 4 were living abroad. In the 6 remaining, only one showed a thyroid mass, basal calcitonin was normal in all patients except one, and pentagastrin-stimulated calcitonin was negative in 2 patients. Total thyroidectomy was performed in all cases. Histology showed C-cell hyperplasia in all patients and MTC in 5 of them. In MEN 2A and FMTC DNA analysis allows the identification of RET mutation carriers, in which presymptomatic thyroidectomy allows and improvement in survival.

[Analysis of 500 liver transplantations at Bellvitge Hospital, Spain]. / Análisis de 500 trasplantes hepáticos en el Hospital de Bellvitge.

BACKGROUND: We present the experience of the liver transplantation program at the Hospital of Bellvitge with 500 transplantations performed during 15 years, to describe changes in liver transplantation observed throughout the time and to analyze the long term results. PATIENTS AND METHOD: Five groups each one including 100 consecutive transplantations are studied. RESULTS: The main indications were hepatocellular carcinoma (23%), alcoholic cirrhosis (22.8%), and post-hepatitis C cirrhosis (18.8%). Sixty-five retransplantations were performed in 59 patients (13%), being the more frequent indications arterial thrombosis (13 patients) and primary nonfunction of graft (10 patients). In 10 patients a hepatorenal transplantation was performed. In group I, the most frequent donor cause of death was cranial traumatism (80%), while in group V it was the vascular pathology (52%). There were other significative differences between these groups of patients (I vs V): patients with stage 2 or 3 from UNOS status (45 vs 19%), blood use (29.6 [26] vs 4.6 [5.3] PRBC), ICU stay (13 [13] vs 7.4 [11] days), hospital stay (40 [52] vs 23.7 [17] days), rejection rate (46 vs 20%) and primary graft nonfunction (9 vs 3%). However, the infection rates (48 vs 54.5%) and biliary tract complications (26 vs 20%) have not shown statistically significant differences. Actuarial one and 5-year survival are 83 and 70% respectively. CONCLUSIONS: An important and progressive improvement of liver transplantation results has been observed. However, de novo tumours, hepatitis C virus recurrence and chronic rejection can limit long term results.
