The purpose of this retrospective study was to characterize the changes in organ dysfunction among patients with acute necrotizing pancreatitis complicated by sepsis who underwent open necrosectomy.

Baseline demographic and clinical characteristics (including age, gender, and education level) were collected from medical records. Organ dysfunction was defined according to the Sequential Organ Failure Assessment (SOFA) score. SOFA scores were extracted at predefined time points: preoperative (T1), postoperative day 1 (T2), postoperative day 3 (T3), and either postoperative day 7 or hospital discharge, whichever occurred first (T4). Postoperative survival status up to 1 year was obtained from the institutional database.

Inclusion Criteria:

1. Patients 18 years or older

Diagnosis of Acute pancreatitis according to the revised Atlanta classification, requires two of thefollowing three criteria: (A) typical abdominal pain, (B) an increase in serum amylase or lipaselevels higher than three times the upper limit of normality, and (C) signs of AP in imaging3)Patients with confirmed or suspected infected pancreatic or peripancreatic necrosis werescheduled for open necrosectomy
3. Meet Sepsis-3 criteria
