Background Hepatoblastoma is the most common primary malignant liver tumor in children and is usually diagnosed during the first 3 years of life. Overall survival has increased 50% due to chemotherapeutic schemes, expertise surgery centers, and liver transplantation. Methods A retrospective collection of data was performed from pediatric patients with diagnosis of hepatoblastoma. Variables included demographic, diagnostic tools and histological classification; chemotherapy and surgical treatment; and outcomes and patient survival. The PRETEXT classification was applied, which included the risk evaluation, and according to the medical criterion in an individualized way, underwent resection or transplant. The morbidity of patients was evaluated by the Clavien-Dindo classification. Statistical analysis was performed according to the distribution of data and the survival analysis was carried out using the Kaplan-Meier method. Results The patients (n = 16) were divided in a resection group (n = 8) and a transplant group (n = 8). The median age at the time of diagnosis was 13.5 months. The motive for the initial consultation was the discovery of a mass; all patients had high levels of &agr;-fetoprotein and an imaging study. Ten of 16 patients required chemotherapy before the surgical procedure. In the resection group, 5 of 8 patients were classified as Clavien I and 4 of 8 patients of the transplant group were classified as Clavien II. Patient survival at 30 months was 100% in the resection group and 65% in the liver transplantation group. Conclusions To our knowledge, this is the first case report of pediatric patients with hepatoblastoma and liver resection or transplant in Colombia and Latin America. Our results are comparable with the series worldwide, showing that resection and transplant increase the survival of the pediatric patients with hepatoblastoma. It is important to advocate for an increase of reporting in the scientific literature in Latin America.

BACKGROUND Around 2.4% of the worlds population is infected with hepatitis C virus (HCV), and it is the most common cause of liver transplantation (LT) in the world. Latin America (LA), with nearly 9% of the world population, has had a continuous increase in the number of LTs per year. Yet, due to the lack of mandatory data collection and a well-developed health-care system, access to transplantation is limited in most LA countries. We report the first LA experience of HCV-infected LT patients. METHODS We performed a retrospective cohort study by reviewing the medical histories of all HCV-infected LT patients between 1996 and 2016 who acquired HCV before their LT, at the Fundación Valle del Lilí, Cali, Colombia. RESULTS Between January 1996 and December 2015, a total of 770 LTs were performed, of which 75 had a cirrhotic liver due to HCV infection. With a median follow-up time of 24.4 months (interquartile range [IQR] 4.7-61.2 months), patient survival was 44.9% and 66.9% for the time periods 1996-2006 and 2007-2015, respectively. Hepatocellular carcinoma (HCC) was present in 30.6% of the patients, and overall postoperative complications had an incidence of 80%. CONCLUSIONS This is the first report of LT in HCV-infected patients in Colombia and in LA. Our results are comparable to those of other transplant centers worldwide with regard to postoperative complications and patient survival. Patients with LT in the 1996-2006 time frame had higher morbidity and mortality. Studies including larger numbers of patients are needed to determine the reason for this finding.

Liver transplantation is an option that improves quality of life and prolongs life expectancy in patients with different types of liver disease. Liver transplantation is controversial for colorectal metastases and is not recommended in clinical practice guidelines. In this case report, we present, to our knowledge, the first liver transplantation for colorectal metastases conducted in Colombia, with a successful follow-up of more than 2 years. Patients with these characteristics who underwent liver transplantation experience reduced mortality and exponentially improved quality of life.

Case series Patient: Male, 38 • Male, 48 Final Diagnosis: En-bloc transplantation (liver, kidney, pancreas) Symptoms: Encephalopathy • adynamia • ascites • asthenia Medication: — Clinical Procedure: En-bloc transplantation Specialty: Transplantology Objective: Unusual setting of medical care Background: En-bloc transplantation is a surgical procedure in which multiple organs are transplanted simultaneously. It has some similarities with multi-organ transplantation but offers certain advantages. This report highlights the experience of our interdisciplinary group regarding the treatment and follow-up of patients who received en-bloc transplantation, with the aim of encouraging the development of this surgical technique. Case Report: The first case is a 38-year-old patient with type 1 diabetes mellitus, liver cirrhosis, and chronic kidney failure who received an en-bloc transplant of the liver, pancreas, and kidney with no intraoperative complications. He had a prolonged hospital stay due to anemia and systemic inflammatory response syndrome, which were resolved successfully. At follow-up, he had no requirement for insulin or for dialysis, or for new interventions. The second case describes a 48-year-old patient with type 2 diabetes mellitus, renal failure, and liver cirrhosis who received an en-bloc transplant of the liver, pancreas, and kidney with no complications. During the postoperative period, the patient suffered a possible episode of acute tubular necrosis, which evolved towards improvement, with a tendency to normal metabolic and renal functioning, with no additional events. The patient is currently in follow-up and is insulin-independent. Conclusions: En-bloc transplantation is a safe procedure, which is technically simple and which achieves excellent results. This procedure is indicated in patients with end-stage renal disease, cirrhosis, and diabetes mellitus that is difficult to control.

Case report of cadaveric kidney transplantation with renal-portal venous drainage: A feasible way for a venous drainage in a complex generalized thrombosed vessels setting

Mauricio Millán; Luis Armando Caicedo; Jorge I. Villegas; Oscar Serrano; Liliana Caicedo; Mauricio Duque; Laura S. Thomas; Gabriel J. Echeverri

Highlights • One of the frequent complications suffered by patients with chronic renal failure is the lack of vascular access due to venous thrombosis.• Patients with vascular structural alteration are technicaly challenging.• Kidney transplant with portal venous drainage is an alternative in a general thrombosed vessels setting.• The implant of the renal graft was undertaken via an anastomosis at the lateral side of the renal vein to the portal vein.
