Biological alterations such as anaemia, neutrophilia, platelet disorders, increased liver enzymes and decreased albumin/globulin (A/G) ratio may occur frequently (Ferrari et al., 2024; Latifi et al., 2020; O'Brien et al., 2013; Sabattini et al., 2018; Sabattini et al., 2022; Spangler & Kass, 1998), but haematological and biochemical changes after surgery have yet to be reported. This evidence concerns the gene ALB and anemia (phenotype).
