RESUMO

PURPOSE: The advantages of biological meshes for ventral hernia repair are still under debate. Given the high financial cost, the proper indications for biological meshes should be clarified to restrict their use to properly selected patients. METHODS: A retrospective database was instituted to register all cases of abdominal wall defect treated with biological meshes from 1/2010 to 3/2016. RESULTS: A total of 227 patients (mean age: 64 years) whose ventral abdominal defects were reconstructed with a biological mesh were included in the study. Patients were divided according to the 2010 four-level surgical-site complication risk grading system proposed by the Ventral Hernia Working Group (VHWG): Grade 1 (G1, 12 cases), Grade 2 (G2, 68 cases), Grade 3 (G3, 112 cases), and Grade 4 (G4, 35 cases). The surgical site complication rate was higher in patients with one or more risk factors (33.6% vs 19% in patients with no risk factors) (P = 0.68). Statistically significant risk factors associated with the onset of one or more postoperative surgical site complications included: diabetes, coronary artery disease, immunosuppression, and obesity. Recurrence was more common in patients with surgical site complications and mainly associated with infection (38.9%) and wound necrosis (44.4%), and in cases of inlay positioning of the mesh (36%). CONCLUSIONS: Due to their high costs, biological mesh should not be used in G1 patients. In infected fields (G4), they should only be used if no other surgical solution is feasible. There is a clear need to prospectively evaluate the performance of biological meshes.

RESUMO

INTRODUCTION: Intestinal duplication is rarely reported in adulthood and often remains undiagnosed until onset of complications. We describe the case of a 39 year old woman who came to our observation for acute abdomen due to a combination of double intestinal duplication (colon and ileum) and an incidental neuroendocrine tumor of the appendix. MATERIALS AND METHODS: A 39 year old woman who was admitted at with upper abdominal pain. Multisliced spiral CT scan showed a cystic lesion suggestive of an inflammed Meckel's diverticulum.The patient was underwent an urgent explorative laparoscopy. The intraoperative findings revealed a cystic lesion of the anti-mesenteric side of transverse colon, apparently dissectable from the bowel and a second lesion with a strongly adherent and unresectable from the anti-mesenteric aspect of the small bowel. A combined appendectomy was also performed. The histological diagnosis was consistent with a typical intestinal duplication for both intestinal lesionsand an incidental 2mm carcinoid tumor was also found in the appendix. The postoperative course was uneventful and the patient was discharged on p.o. day 5. At the presenttime she is well and following a regular oncologic follow-up. DISCUSSION: The rarity of this case is due to the concomitant presence of an incidental, sincronous, appendiceal NET. The elective treatment is surgical resection. CONCLUSION: Intestinal duplication in the adulthood is extremely rare and may either have an acute presentation as acute abdomen or represents an incidental finding of mass. We suggest that, once the diagnosis is suspected patient must undergo surgery.

RESUMO

BACKGROUND: Polycystic liver disease (PLD) is due to a genetic disorder and frequently coexists with polycystic kidney disease (PKD). If the cysts produce symptomatology owing to their number and size, many palliative treatments are available. When none of the liver parenchyma is spared, or kidney insufficiency is marked, the only potentially curable treatment is liver transplantation (LT). CASE REPORT: A 49-year old woman, diagnosed with PLD and PKD, was listed in January 2008 for combined LT and kidney transplantation (KT). A compatible organ became available 8 months later. Despite preserved liver function, the patient's clinical condition was poor; she experienced dyspnea, advanced anorexia, abdominal pain, and severe ascites. At LT, which took 9 hours and was performed using the classic technique, the liver was hard, massive in size (15.5 kg), and not dissociable from the vena cava. The postoperative course was complicated by many septic episodes, the last one being fatal for the patient at 4 months after transplantation. DISCUSSION: LT for PLD in many series shows a high mortality rate. The Model for End-Stage Liver Disease (MELD) score does not stage patients properly, because liver function is usually preserved. The liver can achieve a massive size causing many symptoms, especially malnutrition and ascites; in this setting LT is the only possible treatment. Patients with a low MELD score undergo LT with severe malnutrition that predisposes them to greater susceptibility to sepsis. To identify predictor factors, beyond MELD criteria that relate to the increased liver volume before development of late symptoms is essential to expeditiously treat patients with the poorest prognosis to improve their outcomes.

RESUMO

Tumor progression before orthotopic liver transplantation (OLT) is the main cause of dropouts from waiting lists among patients with hepatocellular carcinoma (HCC). Performing a porto-caval shunt (PCS) before parenchymal liver transection has the potential to allow an extended hepatectomy in patients with decompensated liver cirrhosis, reducing portal hyperflow and therefore the sinusoidal shear-stress on the remnant liver. We report the case of a 59-year-old man affected by hepatitis C virus (HCV)-related decompensated liver cirrhosis (Child Pugh score presentation, C-10; Model for End Stage Liver Disease score, 18) and HCC (2 lesions of 2 and 2.8 cm). The patient began the evaluation to join the OLT waiting list, but, in the 3 months required to complete the evaluation, he developed tumor progression: 3 HCC lesions, the largest 1 with a diameter of about 4.4 cm. These findings excluded transplantation criteria and the patient was referred to our center. After appropriate preoperative studies, the patient underwent a major liver resection (trisegmentectomy) after side-to-side PCS by interposition of an iliac vein graft from a cadaveric donor. The patient overcame the worsened severity of cirrhosis. After 6 months of follow-up, he developed 2 other HCC nodules. He was then included on the waiting list at our center, undergoing OLT from a cadaveric donor at 8 months after salvage treatment. At 36 months after OLT, he is alive and free from HCC recurrence. Associating a partial side-to-side PCS with hepatic resection may represent a potential salvage therapy for patients with decompensated cirrhosis and HCC progression beyond listing criteria for OLT.

RESUMO

BACKGROUND: The system that controls the waiting list (WL) and organ allocation for liver transplantation (OLT) seeks to achieve 3 main goals: objectivity, low dropout risks and good post-OLT results. We sought to prospectively validate a priority allocation model that is believed to achieve objectivity without penalizing dropout risk and post-OLT results. METHODS: We evaluated a study group of 272 patients enrolled in 2006-2007. WL candidates were divided into 2 categories: cirrhotic patients classified according to Model for End-Stage Liver Disease (MELD) score (MELD list and patients with hepatocellular carcinoma (HCC) organized according to a specific score (non-MELD list). The allocation algorithm for donor-recipient match assigned an optimal graft to the first MELD candidate with a MELD score of >or=20; a suboptimal graft, to the first non-MELD patient. A respective control group of 327 patients transplanted from 2003-2006 was characterized by a unique WL with a free allocation policy. We performed an interim analysis of this prospectively controlled study. RESULTS: Although the study group showed a lower percentage of OLT (P < .05) than the control group (37% vs 45%), it selected patients for OLT based on a higher MELD score (P < .05), thus obtaining similar dropout, post-OLT survivals, and intention-to-treat (ITT) survival probabilities as the controls. Among MELD patients, we observed a significantly reduced dropout and better ITT survival profiles than those of the control group (P = .02), whereas the similar results were delivered among non-MELD patients (P > .05). Among patients with a MELD score of >or=20, the prevalences of suboptimal grafts (0% vs 48%) and of early graft losses (0% vs 21%) were lower in the study than in the control group (P < .05). CONCLUSIONS: We prospectively validated a priority allocation model based on objective criteria that achieved high ITT survival rates.

RESUMO

BACKGROUND/AIM: Prognosis assessment in surgical patients with hepatocellular carcinoma (HCC) remains controversial. The most widely used HCC prognostic tool is the Barcelona Clinic Liver Cancer (BCLC) classification, but its prognostic ability in surgical patients has not been yet validated. The aim of this study was to investigate the value of known prognostic systems in 400 Italian HCC patients treated with radical surgical therapies. METHODS: We analyzed a prospective database collection (400 surgical, 315 nonsurgical patients) observed at a single institution from 2000 and 2007. By using survival times as the only outcome measure (Kaplan-Meier method and Cox regression), the performance of the BCLC classification was compared with that of Okuda, Cancer of the Liver Italian Program, United Network for Organ sharing TNM, and Japan Integrated Staging Score staging systems. RESULTS: Two hundred twenty-five patients underwent laparotomy resection; 55, laparoscopic procedures (ablation and/or resection); and 120, liver transplantations. In the surgical group, BCLC proved the best HCC prognostic system. Three-year survival rates of patients in BCLC Stages A, B, and C were 81%, 56%, and 44% respectively, (P < .01); whereas all other tested staging systems did not show significant stratification ability. When all 715 HCC patients were considered, surgery proved to be a significant survival predictor in each BCLC stage (A, B, and C). CONCLUSIONS: BCLC staging showed the best interpretation of the survival distribution in a surgical HCC population. The BCLC treatment algorithm should consider the role of surgery also for intermediate-advanced stages of liver disease.

RESUMO

BACKGROUND: Tumor progression before liver transplantation (OLT) is the main cause of dropout from the waiting list (WL) of patients with hepatocellular carcinoma (HCC). The aim of this study was to show a correlation between adopted dropout criteria and dropout/intention-to-treat survival rates of WL HCC patients. METHODS: The study period was 2000 to 2007. The dropout criteria were macroscopic vascular invasion, metastases, or a poorly differentiated tumor. Adult patients with benign chronic liver disease enlisted for primary OLT in the same period represented the control group. RESULTS: Dropout probability of study (n = 128) versus control group (n = 377) subjects was similar: namely, 12% at 1 year in both groups (P = NS). Intention-to-treat survival curve of the HCC group overlapped that of the benign group (5-year survival rates were 73% and 71%, respectively; P = NS). At the time of listing, 103 study group patients were within the Milan criteria (MC): among these patients, 29 (28%) showed tumor progression beyond MC before OLT. Simulating the dropout of these 29 patients at the time of diagnosis of tumor progression, we compared the dropout probability of the 103 patients within MC with that of the control group. As a result, the 1- and 2-year dropout rates became 37% and 53%, respectively, in the study group, which were significantly higher than those in the controls (P < .01). CONCLUSION: HCC patients on the WL showed a significantly greater dropout rate than subjects with benign cirrhosis when too restrictive radiologic dropout criteria were used. The adoption of criteria more related to biological aggressiveness of a tumor decreased the dropout risk for HCC patients without impairing their intention-to-treat survival rates.

RESUMO

INTRODUCTION: Organ transplant recipients show an increased incidence of cancer ranging from 4% to 16% owing to several causes: immunosuppression, viral infection, individual predisposition, and so on. MATERIALS AND METHODS: We retrospectively reviewed the records of 43/683 (6.3%) recipients of 734 liver transplants performed from November 1991 to November 2008 who experienced a de novo neoplasm. CONCLUSION: Alcohol abuse significantly increased the rate of all de novo neoplasms and particularly pharyngogastroesophageal cancers among population of liver transplant recipients. Minimization of immunosuppressive therapy is necessary to reduce the risk of a de novo neoplasm. Strict posttransplant follow-up is required to identify early gastroenteric tumors.

RESUMO

BACKGROUND AND AIM: Hepatitis C virus (HCV)-related cirrhosis is one of the leading indication for liver transplantation (LT) and a major risk factor for the development of hepatocellular carcinoma (HCC). HCV recurrence after LT is universal. This study evaluated HCV recurrence and survival in patients transplanted for HCV and HCC. METHODS: We evaluated all adults transplanted for HCV cirrhosis between January 1999 and December 2006, HCC was diagnosed on the explant and HCV recurrence confirmed on protocol liver biopsies performed at 6 months and yearly after LT. The sustained viral response (SVR) was defined as HCV-RNA undetectable at 6 months after therapy discontinuation. The patient survival rates were assessed with Kaplan-Meier curves and the chi-square test was used when appropriate. RESULTS: Two hundred sixteen patients underwent LT for HCV including 153 men and 63 women of mean age 54 years with a mean follow-up of 35 months. There were 71 (33%) HCC(+) patients. At 1, 3, and 5 years from LT severe fibrosis (Scheuer 3-4) due to the HCV recurrence was reported in 18%, 14%, and 11% for HCC(+) and 14%, 16%, and 28% for HCC(-) patients respectively (P=NS). HCC recurred only in 3 (4%) patients at a mean follow-up of 3 years. Patients who received antiviral treatment after LT were 10% HCC(+) and 12% HCC(-) patients (P=NS). SVR was seen in 3/7 (43%) of HCC(+) and in 10/18 (55%) of HCC(-) patients (P=NS). At 1, 3, and 5 years the patient survivals was 91%, 86%, and 86% for HCC(+) and 94%, 86%, and 83% for HCC(-) patients, respectively (P=NS). CONCLUSIONS: Severe fibrosis due to HCV recurrence, which increases over time, involves one third of transplanted patients at 5 years after LT. The long-term survival was identical among HCC(+) compared to HCC(-) recipients. The recurrence of HCC was negligible and did not affect patient survival.

RESUMO

INTRODUCTION: Liver transplantation represents the gold standard for the treatment of chronic liver disease. The whole transplantation process was assessed using an intention-to-treat analysis and considering patients from the time of their inclusion on the list and throughout lengthy follow-up. MATERIALS AND METHODS: From January 1, 1999 to June 1, 2004, 373 adults joined the waiting list for liver transplantation at our institution. The main variables analyzed were: age, gender, etiology, Model for End-stage Liver Disease score, Child-Pugh class, United Network for Organ Sharing (UNOS) status. Global survival was evaluated using intention-to-treat analysis from the time of patient inclusion in the list to the end of their late follow-up. RESULTS: The median waiting time was 20 months (range 0.1 to 70.2). By univariate analysis, the variables significantly influencing survival when patients joined the waiting list were: encephalopathy; ascites, poor nutritional status, Child-Pugh class C, UNOS 2, hepatitis C virus (HCV) and bilirubin > 2 mg/dL. By multivariate analysis, only HCV-related cirrhosis emerged as having an independent prognostic value. By intention-to-treat analysis, the 5-year survival rate was 67% and 79% for HCV-positive and HCV-negative patients, respectively (P = .0003). CONCLUSIONS: HCV-related cirrhosis is an independent prognostic factor for survival according to an intention-to-treat analysis. Different inclusion criteria or treatments while on the waiting list and after transplantation need to be considered in the future for HCV-positive patients.

RESUMO

BACKGROUND/AIMS: The aim of this retrospective study is to analyze the prognostic impact of Model for End-Stage Liver Disease (MELD) score in patients undergoing liver transplantation (OLT) with suboptimal livers. METHODS: Between January 2002 and January 2006, 160 adult patients with liver cirrhosis received a whole liver for primary OLT at our institution including 81 with a suboptimal liver (SOL group) versus 79 with an optimal liver (group OL). The definition of suboptimal liver was: one major criterion (age >60 years, steatosis >20%) or at least two minor criteria: sodium >155 mEq/L, Intensive Care Unit stay >7 days, dopamine >10 microg/kg/min, abnormal liver tests, and relevant hemodynamic instability. RESULTS: Baseline recipients characteristics were comparable in the two study groups. The SOL group had a significantly greater number of early graft deaths (<30 days) than the OL group, while the 3-year Kaplan-Meier patient survivals were similar. Using logistic regression, MELD score was significantly related to patient death only in the SOL group (P = .01), and the receiver operator characteristics curve method identified 17 as the best MELD cutoff with the 3-year survival of 93% versus 85% for MELD < or =7 versus >17, respectively (P > 05). In comparison, it was 94% and 72% in the SOL group (P < .05). Similarly, MELD >17 was significantly associated with early graft death rates only in the SOL group. CONCLUSION: This study advised surgeons to not use suboptimal livers for patients with advanced MELD scores, thus supporting a donor-recipient matching policy.

RESUMO

BACKGROUND/AIM: The main indications for combined liver and kidney transplantation (CLKT) are as follows: (1) cirrhosis with renal damage dependent or not upon liver disease, (2) renal failure with dialysis and concomitant liver end-stage disease, (3) congenital diseases, and (4) enzymatic liver deficiency with concomitant renal failure. The aim of this study was to evaluate our results with CLKT both in adult and pediatric patients. METHODS: From September 1995 to September 2006, 15 CLKT (2.8%) among 541 liver transplantations included 4 pediatric patients (27%). The main indications for CLKT were hepatitis C virus (HCV) and polycystic diseases in adult patients, and primary hyperoxaluria in pediatric patients. RESULTS: The double transplantation was performed from the same donor in all cases. All adult patients received whole liver grafts, whereas 3 split transplants and 1 whole liver graft were transplanted in the pediatric patients. Median liver and kidney cold ischemia times were 468 and 675 minutes, respectively. After a median follow-up of 36 months (range, 1-125), the overall survival rate was 80%. Five-year patient and graft survival rates were 100% for adult CLKT, whereas they were 50% for pediatric patients. We observed only 2 cases (18%) of delayed renal function, requiring temporary hemodialysis with progressive graft improvement. There was only 1 case of kidney retransplantation due to early graft nonfunction in a pediatric patient. CONCLUSION: Although CLKT is related to major surgical risks, results after transplantation are satisfactory with an evident immunological advantage.

RESUMO

OBJECTIVE: The objective of this study was to analyze experience on pediatric liver transplantation (LT) between June 1993 and September 2006, including split liver transplantation (SLT), living donor liver transplantation (LDLT), and auxiliary partial orthotopic liver transplantation (APOLT). Furthermore, hepatocyte transplantation (HT) had a role in one patient with metabolic disease. METHODS: From November 1990 to September 2006, 657 LTs were performed including 63 pediatric LTs (9.6%) in 57 patients (32 boys and 25 girls). Six were retransplantations (9.5%). Thirty-two patients (57%) were younger than 5 years. The types of graft included the following: 26 whole organs (41%), 32 in situ split organs (51%), 4 reduced-size organs (6%), and 1 graft from a living donor (2%). Two patients received an APOLT, 4 patients received a combined kidney-liver transplantation (CKLT), and 1 patient received HT. Of the 63 pediatric LTs, 16 were behaved to be highly urgent (25%). RESULTS: Overall 1-, 3-, 5-, and 10-year patient survival rates were 82%, 82%, 78%, and 78%, respectively. Overall 1-, 3-, 5-, and 10-year graft survival rates were 76%, 76%, 72%, and 72%, respectively. In patients younger than 1 year, the 5-year survival rate was 100%. Perioperative mortality was 8.8%. Vascular complications occurred in 4 patients (6.3%). Six children required retransplantation due to primary nonfunction (PNF) in 4 cases (7%) and vascular thrombosis in 2 cases (3.5%). CONCLUSIONS: Cholestatic liver disease and age younger than 1 year were the best prognostic factors for excellent survival.

RESUMO

AIM: To assess the indications and results of endoscopic retrograde cholangio-pancreatography (ERCP) in patients who have undergone ortotopic liver transplantation (OLT). METHODS: We reviewed data from 42 consecutive patients who underwent ERCP for biliary complications after OLT over an 8-year period, in particular recording indications and success of the treatment after a mean of 17 months follow-up. RESULTS: Cholangiograms performed in 33/42 patients (79%) displayed anastomotic strictures in 17 patients (52%), bile duct stones in 8 (24%), both bile duct stones and an anastomotic stricture in 2 (6%), papillary stenosis in 1 (3%), and anastomotic biliary leakage in 1 (3%). In contrast, the contrastogram was normal in four patients (12%). Stone extraction was completed in 9/10 patients (90%) with a mean of 1.2 sessions, while stricture dilation was achieved in 12/19 patients (63%) after a mean of 1.7 sessions, by stent positioning (n = 7), balloon dilation (n = 4), or Soehendra dilator (n = 1). Both biliary leakage and papillary stenosis were cured by ERCP. Only one procedure-related complication -- severe pancreatitis (2.4%) -- was observed and no mortality. CONCLUSION: ERCP is a safe and effective mode of management of bile duct complications after OLT. It should be attempted before a surgical approach. Better results are obtained for treatment of biliary stones than of anastomotic strictures.

RESUMO

Liver transplantation still represents the only effective treatment for patients with liver failure, but many patients die while awaiting transplantation, even though many attempts have been made to increase the organ procurement rates and to partially support hepatic function in recent years. Our aim was to design an "open" ex vivo perfused liver model to simplify liver support using an isolated porcine liver perfused with arterial and portal blood from the recipient pig, while monitoring the metabolic capacity of the supporting graft. It was possible to perfuse the isolated liver for 6 hours as a bridging procedure with satisfactory hemodynamic homeostasis controlled by software biofeedbacks.

RESUMO

This prospective study analyzed the dropout probability and intention-to-treat survival rates of patients with hepatocellular carcinoma (HCC) selected and treated according to our policy before liver transplantation (LT), with particular attention to those exceeding the Milan criteria. Exclusion criteria for LT were macroscopic vascular invasion, metastases, and poorly differentiated disease at percutaneous biopsy. A specific multi-modal adjuvant algorithm was used to treat HCC before LT. A total of 100 HCC patients were listed for LT: 40 exceeded the Milan criteria in terms of nodule size and number (MILAN OUT) either at listing or in list, while 60 patients continued to meet the criteria (MILAN IN). The Milan criteria did not prove to be a significant predictor of dropout probability or survival rates using Cox's analysis. Cumulative dropout probability at 6 and 12 months was 0% and 4% for MILAN OUT, and 6% and 11% for MILAN IN. The intention-to-treat survival rates at 1 and 3 years were 95% and 85% in MILAN OUT, and 84% and 69% in MILAN IN. None of the 68 transplanted patients had recurrent HCC after a median 16-month follow-up (0-69 months). In conclusion, LT may be effective for selected, aggressively-treated HCC patients exceeding the Milan criteria.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) reinfection after liver transplantation is a virtually constant finding and leads to chronic hepatitis and cirrhosis in variable proportions. This study aimed to assess the safety and efficacy of alpha-interferon (IFN) plus ribavirin for recurrent HCV following liver transplantation. PATIENTS AND METHODS: Thirty of 55 patients (54.5%) with histologically proven HCV recurrence after liver transplantation were given antiviral therapy (alpha-IFN at a dose of 6 MU x 3 x week IM associated with oral ribavirin 1 g/d for 12 months) and followed up for a further 12 months after the end of the treatment. Liver and renal function tests, hemocytometric values, and HCV-RNA were assessed every 3 months throughout the therapy and follow-up. Liver biopsy was performed before and after the treatment and after another 12 months of follow-up. RESULTS: Eight patients (26.7%) were withdrawn from the treatment due to adverse events and another 8 (26.7%) needed a dosage reduction. Eleven patients (36.7%) had a biochemical and virological response, becoming aminotransferase and HCV-RNA negative at the end of the treatment; 6 patients (20%) still had a sustained response after 12 months of follow-up. All 6 patients are clinically stable at 6 years after completing the antiviral therapy. A low viral load before therapy was a positive predictor of sustained response. No histologically significant improvement was seen at the end of the therapy or after the follow-up. CONCLUSIONS: The combination of alpha-IFN plus ribavirin induced a sustained virologic response in 20% of liver transplant recipients with recurrent HCV, but intolerance of the therapy prompted its discontinuation or a dosage reduction in a large proportion of patients. However, we have observed a long-term efficacy of the antiviral therapy in the sustained responders.

RESUMO

BACKGROUND: This study aimed to evaluate the incidence of cystadenoma diagnosis in a series of laparoscopic treatments for nonparasitic liver cysts, as well as its management. METHODS: From 1996 to 2004, 26 patients with a nonparasitic cyst of the liver were selected for laparoscopic liver surgery. Solitary nonparasitic liver cysts were, whenever feasible, completely enucleated. RESULTS: In four patients, the histopathologic examination showed a cystadenoma. Three patients with 13, 9, and 12-cm cysts, respectively, had undergone complete enucleation of the lesion, with no evidence of recurrence in the follow-up visit. One patient with multicystic liver experienced a recurrence and required an open hepatic resection. CONCLUSIONS: When a complete laparoscopic enucleation of the cyst can be ensured, a strict follow-up assessment should be considered as the definitive treatment, with surgical intervention demanded only in the case of recurrence or high suspicion for malignancy.

RESUMO

BACKGROUND: The impact of liver disease and medical complications on quality of life (QOL) and psychological distress before and after liver transplantation (LT) is a matter of growing interest. METHODS: In a longitudinal prospective study, perceived QOL (LEIPAD Quality of Life test) and psychological distress (Brief Symptom Inventory, BSI) were assessed in 25 cirrhotic patients when they were listed for LT and 1, 3, 6 and 12 months after LT. Patients were also evaluated for medical complications and blood levels of immunosuppressive agents. RESULTS: Overall QOL and psychological distress improved significantly and rapidly in most domains from the first month and up to a year after LT. Medical complications and immunosuppressive agents did not correlate with any changes in QOL and psychological distress after LT. When patients were divided according to liver disease etiology: 1. HCV patients listed for LT had worse QOL levels than the group of patients as a whole or the alcoholic liver disease (ALD) patients; 2. HCV patients reported a significant improvement in QOL only 6 and 12 months after LT, and still suffered more psychological distress 12 months after surgery; 3. in ALD patients, overall QOL and psychological distress improved significantly at all follow-up points after LT; 4. HCV patients reported a worse QOL and greater psychological distress 1 and 3 months after LT than the group as a whole or the ALD patients (p < 0.05). CONCLUSIONS: Liver transplantation improves QOL and psychological distress in most recipients, but not in the early stages after LT in patients transplanted for HCV cirrhosis.
