Table 1 displays the patients’ baseline characteristics grouped by preoperative bilirubin quartiles. Age, gender, BMI, hypertension, diabetes, drinking, smoking, neoadjuvant chemotherapy, MPD, and history of abdominal surgery were statistically non-significant between the four groups. PBD, surgical approach, and pathologic diagnosis exhibited statistically significant differences (p < 0.05). The albumin, ALT, and AST also exhibited significant differences (p < 0.05), while the other laboratory makers were statistically non-significant. Here, GPT is linked to diabetes mellitus.
