Liver Transplantation for Hepatic Trauma: A Study From the European Liver Transplant Registry.

BACKGROUND: Liver transplantation is the most extreme form of surgical management of patients with hepatic trauma, with very limited literature data supporting its use. The aim of this study was to assess the results of liver transplantation for hepatic trauma. METHODS: This retrospective analysis based on European Liver Transplant Registry comprised data of 73 recipients of liver transplantation for hepatic trauma performed in 37 centers in the period between 1987 and 2013. Mortality and graft loss rates at 90 days were set as primary and secondary outcome measures, respectively. RESULTS: Mortality and graft loss rates at 90 days were 42.5% and 46.6%, respectively. Regarding general variables, cross-clamping without extracorporeal veno-venous bypass was the only independent risk factor for both mortality (P = 0.031) and graft loss (P = 0.034). Regarding more detailed factors, grade of liver trauma exceeding IV increased the risk of mortality (P = 0.005) and graft loss (P = 0.018). Moreover, a tendency above the level of significance was observed for the negative impact of injury severity score (ISS) on mortality (P = 0.071). The optimal cut-off for ISS was 33, with sensitivity of 60.0%, specificity of 80.0%, positive predictive value of 75.0%, and negative predictive value of 66.7%. CONCLUSIONS: Liver transplantation seems to be justified in selected patients with otherwise fatal severe liver injuries, particularly in whom cross-clamping without extracorporeal bypass can be omitted. The ISS cutoff less than 33 may be useful in the selection process.

Review of the treatment of liver hydatid cysts.

UNLABELLED: A review was carried out in Medline, LILACS and the Cochrane Library. Our database search strategy included the following terms: "hydatid cyst", "liver", "management", "meta-analysis" and "randomized controlled trial". No language limits were used in the literature search. The latest electronic search date was the 7(th) of January 2014. INCLUSION AND EXCLUSION CRITERIA: all relevant studies on the assessment of therapeutic methods for hydatid cysts of the liver were considered for analysis. Information from editorials, letters to publishers, low quality review articles and studies done on animals were excluded from analysis. Additionally, well-structured abstracts from relevant articles were selected and accepted for analysis. Standardized forms were designed for data extraction; two investigators entered the data on patient demographics, methodology, recurrence of HC, mean cyst size and number of cysts per group. Four hundred and fourteen articles were identified using the previously described search strategy. After applying the inclusion and exclusion criteria detailed above, 57 articles were selected for final analysis: one meta-analysis, 9 randomized clinical trials, 5 non-randomized comparative prospective studies, 7 non-comparative prospective studies, and 34 retrospective studies (12 comparative and 22 non-comparative). Our results indicate that antihelminthic treatment alone is not the ideal treatment for liver hydatid cysts. More studies in the literature support the effectiveness of radical treatment compared with conservative treatment. Conservative surgery with omentoplasty is effective in preventing postoperative complications. A laparoscopic approach is safe in some situations. Percutaneous drainage with albendazole therapy is a safe and effective alternative treatment for hydatid cysts of the liver. Radical surgery with pre- and post-operative administration of albendazole is the best treatment option for liver hydatid cysts due to low recurrence and complication rates.

[Donors yesterday and today: have the characteristics of liver donors changed over the last 15 years?]. / Donantes de ayer y de hoy: han cambiado las características de los donantes de hígado durante los últimos 15 años?

INTRODUCTION: The social, medical and demographic changes of our population and the increase in the number of patients on waiting lists have led to some changes in the selection criteria of organ donors. MATERIAL AND METHOD: A retrospective, descriptive and comparative study of the liver cadaveric donors features accepted in the Liver Transplant Unit in La Fe University Hospital of Valencia (Spain) in 2 different periods. We distributed the cases into 2 groups, including in group A the first 200 first donors (from January 1991 to June 1995) and in group B the last 200 donors (from February 2004 to December 2005). RESULTS: The number of donors increased from 18 during 1991 to 106 in 2006. In group A the mean age was 32.4 years, compared to 52.3 years in group B. In group A, the main cause of death was craneoencephalic traumatism and in group B cerebrovascular accidents. The mean time in the intensive care unit was longer in the second group with 67.2 hours. In group B, considerable atherosclerosis was reported in 17% of cadaveric donors and macroscopic liver steatosis in 29.5%, compared to 5 and 12%, respectively, in group A. CONCLUSIONS: Nowadays, cadaveric liver donors are older, suffer more chronic diseases, die due to cerbrovascular diseases, remain longer in intensive care units and the livers are macroscopically worse compared to donors accepted 15 years ago.
