    ABSTRACT: 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.

    ABSTRACT: OBJECTIVE:: To compare the incidence and severity of biliary complications due to liver transplantation after choledochocholedochostomy with or without a T-tube in a single-center, prospective, randomized trial. SUMMARY BACKGROUND DATA:: The usefulness of the T-tube for end-to-end biliary anastomosis to reduce the incidence of biliary complications in patients undergoing liver transplantation has been controversial. METHODS:: A per-protocol analysis was designed for liver recipients, who were randomly assigned to choledochocholedochostomy with (n = 95) or without (n = 92) a T-tube. RESULTS:: The overall biliary complication rate was 22.5% (n = 42), with no difference between groups (P = 0.35). The majority (66.7%) of complications in the T-tube group were types I and II, whereas 50% were type IIIa and 44% were type IIIb in the non-T-tube group (P < 0.0001). Fewer anastomotic strictures were found in the T-tube group (n = 2, 2.1%) than in the non-T-tube group (n = 13, 14.1%; P = 0.002). No difference in anastomotic biliary leakage was observed between groups. Biliary complication-free survival rates showed that complications appeared earlier in the T-tube group. Graft and patient survival rates were similar in both groups. CONCLUSIONS:: Complications in the T-tube group were less severe and required less aggressive treatment. The incidence of anastomotic strictures was higher in patients with no T-tube. We recommend conducting choledochocholedochostomy with a rubber T-tube during liver transplantation in risky anastomosis and when the bile duct diameter is less than 7 mm.This study is registered at http://www.clinicaltrials.gov: Clinical trial ID# NCT01546064.

    ABSTRACT: Pancreas and kidney transplantation is the treatment of choice for patients with type 1 diabetes mellitus and terminal renal insufficiency. Herein we have presented a series of 35 patients transplanted between 2002 and 2009 including periods before and after 2007 divided based on introduction of some technical aspects. In the first phase (learning period) we have noted complications related to pancreatic surgery with a morbidity among 12 of 18 patients (66.6%). In the second period (stabilization period), complications appeared in 6 out of 17 patients (35.2%; P < .028). The reoperation rate was 83.3% in the learning period and 23.5% in the stabilization period (P < .03). Seven transplantectomies were performed in the first period (P < .004). Five patients died, all of them in the learning group (P < .019). Changes in the technical aspects of the procedure were responsible for improved outcomes obtained among pancreas and kidney transplantations.

    ABSTRACT: Liver transplant in patients with cirrhosis and hepatocellular carcinoma is indicated in the early stages of the disease, which can be achieved with early detection programs using liver ultrasound. Dynamic imaging techniques (ultrasound with contrast, magnetic resonance and tomography) are essential in the diagnosis of this tumour, being able to type the lesion clearly, and, in the majority of cases, lead to the therapy to follow. Surgery is the treatment of choice in these patients, and liver transplant, from a theoretical point of view, is the best. Currently, the size and number of nodes play an important role in the indication of a transplant. The best liver transplant results are obtained in these patients using the Milan criteria, with survivals that exceed 70% and recurrence indices of 15%, at 5 years. Nowadays we have the possibility of using neo-adjuvant treatments to transplant, such as arterial chemoembolisation, percutaneous ablation techniques, and even liver resection as a bridging technique. The survival of patients transplanted due to liver cancer is similar to that obtained for other non-tumour diseases. In Spain it is 1, 3 and 5 years and 82%, 70% and 60%, respectively. The recurrence is between 6.4% and 16%, micro- and macrovascular invasion being its highest risk variable.

    ABSTRACT: Benign hepatic lesions are rare and liver transplantation in these cases is exceptional. We present a review of the subject, commenting on the aspects that have been subsidiary to liver transplantation, of which are highlighted: adenomatosis, polycystosis and hepatic epithelioid haemangioendothelioma (although this process may be a low to intermediate malignant grade). We assessed specific epidemiological, aetiopathogenic, clinical, diagnostic, therapeutic and aspects of the lesions as well as indication for transplantation, and the experiences of different authors on these pathologies.

    ABSTRACT: 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. 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). 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. 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.

    ABSTRACT: Undifferentiated (embryonal) sarcoma of the liver (USL) is a rare malignant hepatic tumor in adults. We report the case of a 40-year-old man with USL who was successfully treated with surgical resection and chemotherapy using ifosfamide and adriamycin. To our knowledge, only 70 cases of USL in adults have been reported worldwide in the 40 years since this clinicopathological entity was defined. Although the prognosis of the disease remains generally poor, long term survival has been achieved in patients with a combination of surgery and chemotherapy.

    ABSTRACT: Anomalies of the liver are infrequent. Agenesis of the right hepatic lobe is an uncommon, usually asymptomatic, entity that is diagnosed through new imaging techniques or during surgery. We present the case of a 51-year-old woman with right hepatic lobe agenesis who underwent technically difficult cholecystectomy for symptomatic gallstones. We discuss the diagnosis and technical difficulties that can be encountered during cholecystectomy when there is right hepatic lobe agenesis.

    ABSTRACT: The best results in the treatment of colorectal cancer metastases to the liver are currently achieved with surgical resection performed under high quality standards. OBJECTIVES. To analyze the results and quality standards of the surgical treatment of colorectal cancer liver metastases in a referral liver unit over an 11-year period. From January 1995 to December 2005, 250 surgical interventions were performed in 221 patients diagnosed with colorectal cancer liver metastases, resulting in 201 hepatic resections. Nineteen percent of patients were >/= 70 years old and comorbidity was present in 54%. Of the 201 hepatic resections, 8.5% were second resections. Major hepatectomy was performed in 39% of the patients. R0 resection was achieved in 85% of the patients. Blood transfusions were not required in 80% of the patients. The median length of postoperative stay was 6 days. Postoperative mortality was nil and morbidity was 19%. Morbidity was associated with the number of resected segments and the need for blood transfusion. The estimated 1-, 3- and 5-year cumulative survival rates were 96%, 69% and 52%, respectively, while estimated disease-free survival rates were 58%, 32% and 24%, respectively. Resection of colorectal cancer liver metastases is an effective therapeutic alternative if high current quality standards are achieved.

    ABSTRACT: We present a study of 28 patients, treated for adenocarcinoma of Vater's ampulla. We emphasize the distinct behavior of each one of the peri-ampullar tumors, those which affect Vater's ampulla yielding the best prognosis. We gathered data regarding gender, age, clinical manifestations, and analytical data. The confirmatory diagnosis gives us 100% of CPRE cases. All of the patients were submitted to surgical treatment with anatomic pathological confirmation of the diagnosis, be it pre or postoperative. We practiced curative surgery in 57.2% of the cases and palliative in 42.8% of the cases. We observed postoperative complications in 17.8% of the patients and peroperative mortality in 3.5%. Actual survival of the series of patients for whom exeretic surgery was performed is significantly superior to that of the other patients.
