This document summarizes a retrospective study of 85 patients with severe acute pancreatitis treated with continuous venovenous hemofiltration (CVVH) and drainage of necrosis fluid under imaging guidance. The study found that intra-abdominal pressure (IAP) directly correlated with organ failure, mortality, and treatment duration and costs. Patients with higher IAP grades had longer CVVH duration, more filter changes, and longer drainage times. IAP values correlated with Sequential Organ Failure Assessment (SOFA) scores and mortality rates. The combination of CVVH and drainage reduced mortality significantly compared to previous studies using early surgery alone.
