Inpatient management of constipation is required when outpatient therapy fails and a child becomes obstipated, and unable to pass stool or gas. There is a growing body of evidence regarding different management strategies for pediatric obstipation. This scoping review aims to map the existing literature regarding inpatient management of pediatric obstipation and identify gaps in knowledge.We will follow the methodology described by the Joanna Briggs Institute and outlined in the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses extension for Scoping Reviews guidelines. The search strategy will include Embase, PubMed, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, Scopus, and gray literature sources. Two independent reviewers will complete screening for eligible studies in two steps: a scan of the title and abstracts followed by a full‐text review. Studies regarding inpatient management of pediatric obstipation, with experimental or cohort design, and with full text available in English will be included. Systematic reviews will also be included. Two independent reviewers will extract data using a standardized form. Extracted data will be presented in visual and narrative formats, including an evidence map to meet the objectives of this scoping review. This protocol is registered at Open Science Framework.In this scoping review, we will outline the current evidence available regarding the efficacy and safety of various hospital interventions for the treatment of pediatric obstipation.","PeriodicalId":501015,"journal":{"name":"JPGN reports","volume":"47 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141269884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
