Effectiveness and safety of proton pump inhibitors for treating acute pancreatitis: A protocol for systematic review and meta analysis.

Background: Previous studies have showed that anti-acid therapy with proton pump inhibitors (PPIs) can inhibit pancreatic secretion and it may be used in treating acute pancreatitis (AP). But at present, there is no systematic reviews for the evidence and the therapeutic effectiveness and safety of anti-acid therapy with PPIs in AP were not unclear. Therefore, we will undertake a systematic review of the literature to summarize previous evidence regarding this topic, in order to clarify the effectiveness and safety of anti-acid therapy with PPIs in AP.

Methods: We will search the EMBASE, WANFANG DATA, Web of Knowledge, China National Knowledge Infrastructure, PubMed, ClinicalTrials.gov and Cochrane Library from inception to June 30,2021 to retrieve relevant studies using the search strategy: ("Proton pump inhibitors" OR "PPI" OR "PPIs" OR "Omeprazole" OR "Tenatoprazole" OR "Pantoprazole" OR "acid suppression therapy" OR "acid suppression drugs") AND ("pancreatitis" OR "pancreatitides"). Two authors independently judged study eligibility and extracted data. Heterogeneity will be examined by computing the Q statistic and I2 statistic.

Results: This study assessed the efficiency and safety of proton pump inhibitors for treating acute pancreatitis.

Conclusions: This study will provide reliable evidence-based evidence for the clinical application of PPIs for treating AP.

Ethics And Dissemination: Ethical approval is unnecessary as this protocol is only for systematic review and does not involve privacy data. The findings of this study will be disseminated electronically through a peer-review publication or presented at a relevant conference.
