Routine laboratory parameters in patients with necrotizing pancreatitis by the time of operative pancreatic debridement: Food for thought

Figure 1 Correlations between dynamic changes of laboratory variables. A: Hemoglobin; B: Total white blood cell count; C: Total platelets count; D: α-amylase; E: Alanine aminotransferase; F: total and post-surgical length of stay. ∆(A-E) = value on admission – value the day before the surgery; ∆(E-A) = value the day before the surgery - value the day before the surgery. ALT: Alanine aminotransferase; AML: α-amylase; Hgb: Hemoglobin; LOS: Length of stay in hospital; OPD: Operative pancreatic debridement; PLT: Total platelets count; WBC: Total white blood cell count.

Figure 2 Receiver operating characteristic curves of aspartate aminotransferase, α-amylase, and direct bilirubin for hospital mortality prediction in acute necrotizing pancreatitis patients. A: Receiver operating characteristic (ROC) curves of aspartate aminotransferase the day before the surgery; B: ROC curves of α-amylase the day before the surgery; C: ROC curves of direct bilirubin (DB) (E) the day before the surgery; D: ROC curves of DB (A/E=value on admission/value the day before the surgery). AML: α-amylase; AST: Aspartate aminotransferase; DB: Direct bilirubin; (E): Day before the operative pancreatic debridement; (A/E): Day of admission/the day before the surgery.
