BACKGROUND: The incidence of acute pancreatitis (AP) is rising around the world, thus further increasing the burden on healthcare services. Approximately 20% of AP will develop severe acute pancreatitis (SAP) with persistent organ failure (>48 h), which is the leading cause of high mortality. To date, there is no specific drug in treating SAP, and the main treatment is still based on supportive care. However, some clinical control studies regarding the superiority of continuous blood purification (CBP) has been published recently. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy of CBP in SAP treatment.
METHODS: Four databases (Medline, SinoMed, EMBASE, and Cochrane Library) were searched for eligible studies from 1980 to 2018 containing a total of 4 randomized controlled trials and 8 prospective studies.
RESULTS: After the analysis of data amenable to polling, significant advantages were found in favor of the CBP approach in terms of Acute Physiology and Chronic Health Evaluation II (APACHE II) score (WMD = -3.00,95%CI = -4.65 to -1.35), serum amylase (WMD = -237.14, 95% CI = -292.77 to 181.31), serum creatinine (WMD = -80.54,95%CI = 160.17 to -0.92), length of stay in the ICU (WMD = -7.15,95%CI = -9.88 to -4.43), and mortality (OR = 0.60, 95%CI = 0.38-0.94). No marked differences were found in terms of C-reactive protein (CRP), alamine aminotransferase (ALT) and length of hospital stay (LOS).
CONCLUSION: Compared with conventional treatment, CBP remedy evidently improved clinical outcomes, including reduced incidence organ failure, decreased serum amylase, APACHE II score, length of stay in the ICU and lower mortality rate, leading us to conclude that it is a safer treatment option for SAP. Furthermore, relevant multicenter RCTs are required to prove these findings.
