Organ Dysfunction Change in Acute Necrotizing Pancreatitis Patients With Sepsis After Open Necrosectomy

Organ Dysfunction Change in Acute Necrotizing Pancreatitis Patients With Sepsis Undergoing Open Necrosectomy

The purpose of this study is to characterize organ dysfunction change in acute necrotizing pancreatitis patients with sepsis after open necrosectomy.

Before surgery, study participants will be asked questions about age, gender, education level, etc. Study participants will also be questioned regarding pancreatic symptoms, as measured on the Patient-Reported Outcome Scale in Acute Pancreatitis (including pain, abdominal distention, eating, bowel movements, nausea and vomiting, thirst, and weakness). Organ dysfunction was defined according to the Sequential Organ Failure Assessment (SOFA) score. The SOFA score will be measured at preoperative (T1), postoperative day 1 (T2), postoperative day 3 (T3), postoperative day 7, or at hospital discharge, whichever comes first (T4). Participants who provide optional consent for biospecimen collection will have peripheral venous blood samples (5-10 mL) collected at predefined preoperative and postoperative time points. Samples will be processed and stored for biomarker analyses, including inflammatory marker measurement, metabolomic profiling, and other exploratory analyses related to the objectives of this study. Following discharge from the hospital, study participants will be contacted at 1 month, 3 months, 6 months, and 1 year after surgery, and asked to complete a survey about their pancreatic symptoms and survival status after surgery.

Inclusion Criteria:

1. Patients 18 years or older
2. Diagnosis of Acute pancreatitis according to the revised Atlanta classification, requires two of the following three criteria: (A) typical abdominal pain, (B) an increase in serum amylase or lipase levels higher than three times the upper limit of normality, and (C) signs of AP in imaging
3. Patients with confirmed or suspected infected pancreatic or peripancreatic necrosis were scheduled for open necrosectomy
4. Meet Sepsis-3 criteria

Exclusion Criteria:

1. Patients refuse to participate
2. Patients undergo repeat surgery on the same site
