Autologous implant for use in the treatment of an individual requiring a liver or pancreas transplant, where the autologous implant can be obtained by a procedure that involves the inoculation of a porous matrix based on a polymer or a mixture of polymers biologically compatible 5 with vital liver and pancreatic cells of the person, where the porous matrix can be obtained by compacting a mixture of polymer particles with a grain size in the range of 20 to 950 mm and sodium chloride particles with a size of grain in the range of 90 to 670 mm and subsequently removing sodium chloride and presenting the porous matrix pores with a size of 130 mm or less and pores with a size of 370 mm or more and the degree of porosity is the numerical indication in % with respect to the proportion of the volume of pores in the total volume of the matrix and amounts to 93% to 98% and presenting the matrix the following distr Pore size ibución: 0.5% to 6% of pores with an average diameter in the range of 70 to 100 mm； 2% to 8% of pores with an average diameter in the range of 101 to 115 mm； 2% to 8% of pores with an average diameter in the range of 116 to 130 mm； 1% to 7% of pores with an average diameter in the range of 131 to 300 mm； from 11% to 23% of pores with an average diameter in the range of 301 to 330 mm； 4% to 10% of pores with an average diameter in the range of 331 to 360 mm； 5% to 17% of pores with an average diameter in the range of 361 to 390 mm； 7% to 19% of pores with an average diameter in the range of 391 to 420 mm； from 3% to 9% of pores with an average diameter in the range of 421 to 450 mm, from 12% to 24% of pores with an average diameter in the range of 451 to 480 mm； and from 5% to 17% of pores with an average diameter in the range of 481 to 510 mm, the pore sizes and the distribution of pore sizes being determined by means of scanning electron microscopy.Implante autólogo para su uso en el tratamiento de un individuo que requiere un trasplante de hígado o de pá
