Approximate.y 20% of patie.ts with acute.pancre.titis de.e.op a se.e.e.dise.se.associate. with complications and hig. risk of mortality. The.purpose.of this study is to re.ie. pathog.0}e.is and prog.ostic factors of se.e.e.acute.pancre.titis （SAP）. An e.te.sive.me.line.se.rch was unde.take. with focusing.on pathog.0}e.is, complications and prog.ostic e.aluation of SAP. Cytokine. and othe. inflammatory marke.s play a major role.in the.pathog.0}e.is and course.of SAP and can be.use. as prog.ostic marke.s in its e.rly phase. Othe. marke.s such as simple.prog.ostic score. have.be.n found to be.as e.e.tive.as multifactorial scoring.syste.s （MFSS） at 48 h with the.advantag.0}of simplicity, e.ficacy, low cost, accuracy and e.rly pre.iction of SAP. Re.e.tly, se.e.al laboratory marke.s including.he.atocrit, blood ure. nitrog.0} （BUN）, cre.tinine. matrix me.alloprote.nase.9 （MMP-9） and se.um amyloid A （SAA） have.be.n use. as e.rly pre.ictors of se.e.ity within the.first 24 h. The.last fe. ye.rs have.witne.se. a tre.e.dous prog.e.s in unde.standing.the.pathog.0}e.is and pre.icting.the.outcome.of SAP. In this re.ie. we.classifie. the.prog.ostic marke.s into pre.ictors of se.e.ity, pancre.tic ne.rosis （PN）, infe.te. PN （IPN） and mortality.
