En el seguimiento, una paciente presentó una metástasis del adenocarcinoma de colon en el hígado y otra una carcinomatosis peritoneal, siendo ambas reintervenidas. Dos pacientes están vivas en el momento actual con un seguimiento de 26 meses de media y una falleció a los 16 meses por progresión de su enfermedad.
