BACKGROUND: Because the effect of low molecular heparin (LMH) on acute ulcer and bleeding complications in patients with severe acute pancreatitis (SAP) is unclear, we investigated the safety and efficacy of early intervention with LMH in patients with SAP.

METHODS: Using the keywords "heparin", "low molecular weight heparin", "pancreatitis", and "severe acute pancreatitis", we searched PubMed, Medline, CNKI, etc. And select the reference documents of the comparative study of traditional treatment and low molecular weight heparin intervention. RevMan was used for the meta-analysis.

RESULTS: A total of 8 references were included in the study, and most of them were low risk bias (medium and high quality). Meta-analysis shows that, The MHS between the two groups is statistically heterogeneous. (Chi2=19.59, I2=95%, P<0.00001), Fixed-effects model (FEM) analysis showed that the MHS of experimental subjects was obviously shorter than that of controls (Z=3.24, P=0.001); The acute physiology and chronic health score (APACHE II) of the two groups were heterogeneous (Chi2=7.24, I2=72%, P=0.03); No heterogeneity was found in the amount of bleeding (Chi2=5.83, I2=31%, P=0.21), FEM analysis showed the number of complications in the experimental group was significantly less than that in the control group (Z=2.70, P=0.007).

DISCUSSION: LMH intervention can dramatically reduce the average hospital stay and complications of patients with SAP, improve treatment efficacy, and has high safety.
