Severe acute pancreatitis (SAP) lacks a definitive treatment option. Although ulinastatin has demonstrated anti-inflammatory and organ-preserving properties, its role in SAP remains unclear due to divergent findings. Hence, we evaluated the efficacy and role of ulinastatin in patients with SAP. A systematic review and meta-analysis were performed according to the 2020 PRISMA guidelines. An extensive search was performed in databases including PubMed, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Embase, IndMED, Cochrane Library, Cochrane Methodology Register, and Cochrane Database of Systematic Reviews to obtain relevant data. Prospective and retrospective studies evaluating patients aged ≥ 18 years with SAP were included. Factors including mortality rate, hospitalisation duration, acute physiology and chronic health evaluation (APACHE-II) score, white blood cell (WBC) count, c-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and time to abdominal pain disappearance were assessed. The pooled analysis of seven studies revealed a significant reduction in mortality risk, risk ratio, (95% CI: 0.20, 0.65); i2 = 53%. No significant reductions in the hospitalization duration mean difference, 4.18 days (95% CI: -9.03, 0.68); i2 = 98% and APACHE-II score mean difference, -0.11 (95% CI: -1.48, 1.26); i2 = 97% were noted. Treatment with ulinastatin demonstrated significant improvements in WBC count, CRP levels, time to abdominal pain disappearance, TNF-α levels, and IL-6 levels. Ulinastatin, administered either alone or in combination with other therapeutic agents, was associated with significant improvements in clinical outcomes and reduced mortality rates in patients with severe acute pancreatitis.
