Orthotopic liver transplantation in a patient with severe haemophilia A and with advanced liver cirrhosis.

A patient with severe haemophilia A underwent orthotopic liver transplantation because of changes correlated to end-stage liver cirrhosis due to hepatitis B, C and D infection. Replacement therapy was carried out for 4 days and the clinical course was uneventful. At the time of reporting the patient has a normal working life. FVIII plasma concentration is normal. The indirect hyperbilirubinaemia may be related to the Gilbert's anomaly of the donor.

Hepatocellular carcinoma: comparison between liver transplantation, resective surgery, ethanol injection, and chemoembolization.

Between January 1989 and June 1997, 533 patients (423 male, 110 female, mean age 61 years, range 22-89 years) with hepatocellular carcinoma (HCC) were observed at our center. We report on 419 patients retrospectively compared for different treatments: liver transplantation (LT; 55 patients), resective surgery (RS; 41 patients), transarterial chemoembolization (TACE; 171 patients) and percutaneous ethanol injection (PEI; 152 patients). The 3- and 5-year actuarial survival rates were, respectively, 72% and 68% for LT, 64 and 44% for RS, 54 and 36% for PEI, and 32 and 22% for TACE. Survival curves were compared for sex, age, tumor characteristics, alphafetoprotein level, Child class, and etiology of cirrhosis. All patient-related characteristics examined (sex, age) are not significantly related to patient survival. Tumor-related variables and associated liver disease variables significantly conditioned survival in relation to different treatments. LT seems to be the treatment of choice for monofocal HCC less then 5 cm in diameter and in selected cases of plurifocal HCC.

Hepatic adenoma and focal nodular hyperplasia: diagnosis and criteria for treatment.

UNLABELLED: Focal nodular hyperplasia (FNH) and adenoma are rare benign hepatic tumors, and the standards for diagnosis and treatment still remain controversial. Usually adenoma is an indication for resection, due to its tendency to bleed and to degenerate; FNH, on the contrary, may be treated conservatively. Preoperation differential diagnosis is, however, difficult, often impossible. MATERIALS AND METHODS: Thirty-eight patients with presumed hepatic adenoma and/or FNH were studied at our department from 1984 to 1996. Preoperative assessment included clinical evaluation and symptoms, laboratory tests, liver biopsy, ultrasound scan, computed tomography scan, magnetic resonance imaging, scintigraphy, and angiography. Thirteen patients had a presumed diagnosis of FNH, 16 of adenoma, and 9 of undetermined benign lesions; 27 had hepatic resections (3 with laparoscopic technique), and 11 were not operated on and are actually under a strict follow-up observation. RESULTS: The final diagnosis was 19 FNH and 19 adenomas (2 of which contained areas of hepatocarcinoma). Presumed diagnosis was confirmed in 71% of cases. Use of oral contraceptives, abdominal symptoms, and pathologic liver test results were frequent in patients with adenomas. There were no deaths after surgery. All resected patients were tumor free during the follow-up, and in 10 of the 11 nonoperated cases, the size of the nodules remained unchanged. We conclude that precise diagnosis of these benign liver tumors remains difficult and sometimes impossible, despite new imaging techniques. Hepatic resections can be performed under very safe conditions; laparoscopic surgery may play a role in selected cases. Adenomas and uncertain cases are clear indications for surgery. Only when a diagnosis of FNH can be firmly confirmed in asymptomatic patients is strict observation without surgery recommended.

Liver transplantation for hepatocellular carcinoma: prognostic factors associated long-term survival.

Between December 1985 and February 1995, 260 orthotopic liver transplantations (OLTX) were performed on 238 patients at Niguarda Hospital. Sixty-three patients had hepatocellular carcinoma (HCC); in 13 of the patients HCC was incidental. All patients had negative lymph nodes. According to the Child classification, 13 patients were Child A, 30 Child B, and 18 Child C. According to the TNM classification, 11 patients were stage I, 22 stage II, 15 stage III, and 15 stage IVa. Pre-OLTX chemoembolization was performed on 25 patients. The perioperative mortality rate was 27% (17 patients). Overall survival and disease-free actuarial survival rates at 1, 3, and 5 years were 94%, 76%, 76%, and 83%, 75%, 75%, respectively. Survival curves were compared for 16 different variables. No difference was observed for all parameters analyzed except tumor site, TNM stage, pre-OLTX AFP levels and vascular infiltration. These results seem to demonstrate that the OLTX for unresectable HCC can be considered in specifically selected cases as the treatment of choice. An adequate tumor staging is also necessary for a better patient selection in order to increase survival.

Is the use of marginal donors justified in liver transplantation? Analysis of results and proposal of modern criteria.

A discrepancy exists worldwide between the number of suitable liver donors and the increasing demand for transplantation. Thus many centers have considered widening their liver donor acceptance criteria and this may increase the incidence of primary dysfunction (PD) with negative effect on the results of transplantation. In order to reduce the incidence of PD and improve patient and graft survival it becomes important to identify those risk factors associated with its occurrence. In a retrospective univariate and multivariate analysis we evaluated several donor, preservation and recipient parameters and their correlation with PD. In our Department 282 orthotopic liver transplantations (OLT) were performed on 256 adult patients over a 10-year period. Excluded were 15 cases with early vascular problems and 4 intraoperative deaths. A complete series of donor, recipient and procedure-related data were analyzed. About 30% of donors showed abnormal values. In 70 cases of PD (26%) there was a 61.4% graft failure rate compared with 15% in the group with immediate function (P < 0.05). Univariate analysis showed donor age, steatosis, ischemia time, amines, oliguria, hypotension and ICU stay to be significantly associated with PD. Multivariate analysis showed steatosis, ischemia time and amine dosage to be independent risk factors for the development of primary non function. In conclusion, the acceptance of marginal donors worsened the results of transplantation, but the rejection of these donors would reduce by about 30% our transplant activity resulting in increased mortality in the waiting list. Combinations of risk factors when possible should be avoided, and ischemia time, as the only variable that can be controlled, should be kept as short as possible.
