ABSTRACT

Background: Preservation solutions are critical for organ transplantation. In liver transplant (LT), the solution developed by the University Of Wisconsin (UW) is the gold-standard to perfuse deceased brain death donor (DBD) grafts. Histidine-Tryptophan-Ketoglutarate (HTK), formerly a cardioplegic infusion, has been also used in solid organ transplantation. Aim: To compare the outcomes of LT in our center using either HTK or UW solution. Patients and Methods: Retrospective study including 93 LT DBD liver grafts in 89 patients transplanted between March 1994 and July 2010. Forty-eight grafts were preserved with UW and 45 with HTK. Donor and recipient demographics, total infused volume, cold ischemia time, post-reperfusion biopsy, liver function tests, incidence of biliary complications, acute rejection and 12-month graft and patient survival were assessed. Preservation solution costs per liver graft were also recorded. Results: Donor and recipient demographics were similar. When comparing UW and HTK, no differences were observed in cold ischemia time (9.6 ± 3 and 8.7 ± 2 h respectively, p = 0.23), biliary complications, the incidence of acute rejection, primary or delayed graft dysfunction. Histology on post-reperfusion biopsies revealed no differences between groups. The infused volume was significantly higher with HTK than with UW (9 (5-16) and 6 (3-11) l, p < 0.001). The cost per procurement was remarkably lower using HTK. Conclusions: Perfusion of DBD liver grafts with HTK is clinically equivalent to UW, with a significant cost reduction.

ABSTRACT

Background: The benefits of hepatic resections for colorectal liver metastases are well known. This is not the case for excisions in the treatment of non-colorectal, non neuroendocrine liver metastases. Aim: To assess the results of liver resection in the treatment of patients with non-colorectal, non neuroendocrine liver metastases. Material and Methods: Electronic database analysis of patients with noncolorectal non-endocrine liver metastases undergoing to hepatectomy between 2000-2009. Results: Seventeen patients aged 22 to 78 years, nine women, were operated. The most common primary tumors were stomach, liver, adrenal glands and uterus. In two cases, a synchronic primary tumor and metßstasis excision was performed. Anatomic seg-mentectomy was performed in 10 cases (58.8 percent) and a mayor surgical resection in 7 patients (41.2 percent). In 15 cases (88.2 percent) the tumor margins were negative. Three patients presented postoperative complications and three patients had hepatic tumor recurrence. No patient died in the peri-operative period. One, two and three years survival were 85, 51 and 51 percent respectively, after a follow-up ranging from 9 to 56 months. Conclusions: The surgical treatment of patients with non-colorectal non-endocrine liver metastases is safe and beneficial in selected patients, with a low rate of complications and good survival rates.


Introducción: Existe un claro beneficio en el tratamiento quirúrgico de las metástasis hepáticas de origen colorrectal y neuroendocrinas; sin embargo, todavía no está bien definida la efectividad de la resección quirúrgica en tumores de origen diferente a los anteriores. El objetivo del presente estudio es dar a conocer los resultados del tratamiento quirúrgico en este grupo de pacientes. Pacientes y Método: Análisis de la base de datos electrónica de los pacientes con metástasis hepáticas de origen no colorrectal ni neuroendocri-na que fueron sometidos a resección hepática en nuestro centro entre los años 2000-2009. Resultados: La serie estuvo constituida por 17 pacientes, nueve mujeres, mediana de edad de 51 años (rango, 22-78). Los principales sitios de origen del tumor primario fueron estómago, hígado, glándulas suprarrenales y útero. En dos casos se realizó cirugía sincrónica del primario y las metástasis; la técnica utilizada fue segmentectomía anatómica en 10 pacientes (58,8 por ciento) y resección anatómica mayor los siete restantes (41,2 por ciento). En 15 pacientes (88,2 por ciento) se logró borde quirúrgico libre de tumor, tres pacientes presentaron complicaciones postoperatorias y en tres hubo recidiva de la lesión hepática. No hubo mortalidad operatoria. Tras un seguimiento de 21 meses (rango, 9-56) la supervivencia al año, a los dos y a los tres años fue de 85 por ciento, 51 por ciento y 51 por ciento respectivamente. Discusión: El tratamiento quirúrgico de los pacientes con metástasis hepáticas de origen no colorrectal ni neuroendocrino es seguro y parece beneficioso en pacientes seleccionados, con baja tasa de complicaciones y con supervivencia favorable.

ABSTRACT

El estallido hepático constituye una de las más graves complicaciones del síndrome de Hellp y es una de sus principales causas de muerte. Dada la presencia de falla hepática y trombocitopenia que constituyen la esencia del síndrome de Hellp, la hemostasia quirúrgica del hígado estallado es extremadamente difícil. Presentamos nuestra experiencia con dos casos de embarazos con síndrome de Hellp y complicados con estallido hepático, que debieron ser operados en nuestro servicio y que pudieron ser controlados mediante el empleo de un empaquetamiento hepático con malla de poliglactina. Los objetivos son discutir las alternativas técnicas para la resolución quirúrgica de esta grave complicación y mostrar los detalles de esta forma de empaquetamiento hepático permanente por nosotros empleado.
