Objectives: Liver transplantation is the treatment of choice for acute and chronic liver failure, for selected cases of tumors, and for conditions resulting from errors in metabolism. This paper reports the experience of a medical center in Latin America.Methods: Were conducted 305 orthotopic liver transplantations on 284 patients between 2004 and 2010. Of these patients, 241 were adults undergoing their first transplantation.Results: The average age of patients was 52 years old, and 62% of the individuals were male. The most common indication was alcoholic cirrhosis. The rate of patient survival after 1 and 5 years was 82 and 72% respectively. The rate of liver graft survival after 1 and 5 years was 78 and 68% respectively. The main cause of death was sepsis. Complications in the hepatic artery were documented for 5% of the patients. Additionally, 14.5% of the patients had complications in the biliary tract. Infections were found in 41% of the individuals. Acute rejection was observed in 30% of the subjects, and chronic rejection in 3%. Conclusion: In conclusion, liver transplantation at our medical center in Colombia offers good mid-term results, with a complication rate similar to that reported by other centers around the world.
Introducción: la enfermedad de Wilson es una enfermedad heterogénea causada por mutaciones en el gen ATP7B. La presentación clínica es variable, en fenotipos hepáticos y neuropsiquiátricos. El objetivo de este estudio es describir una cohorte retrospectiva de pacientes.
Materiales y métodos: estudio retrospectivo descriptivo de pacientes atendidos en el Hospital Pablo Tobón Uribe desde enero de 2004 a septiembre de 2017.
Resultados: se reportaron 27 pacientes, 17 hombres y 10 mujeres. El tiempo de seguimiento medio fue de 2,18 años, el 40 % presentó síntomas neurológicos; el 29 %, psiquiátricos; y el 85 %, alteración hepática. En el laboratorio, el 85 % presentó ceruloplasmina baja; 55 %, cobre urinario alto; en casos con biopsia hepática, 7 tenían depósito de cobre en coloraciones especiales. En neuroimágenes, el 84 % presentó hallazgos sugestivos de enfermedad de Wilson y en 3 casos se documentó una mutación genética patogénica. Durante el seguimiento, el 51 % mejoró clínica o bioquímicamente, el 11 % se mantuvo estable y el 18 % se deterioró. El 88 % de los casos sobrevivió al final del seguimiento.
Conclusiones: este estudio es la cohorte retrospectiva más grande de Colombia. Los resultados son base para nuevos estudios poblacionales buscando de manera activa la enfermedad para documentarla en su fase preclínica y, de este modo, impactar en el pronóstico.
