Background Ultrasound (US) is an alternative to magnetic resonance enterography, and has the potential to significantly reduce waiting times, expedite clinical decision-making and improve patient experience. Point of care US is an advantage of the US imaging modality, where same day scanning, interpretation and treatment decisions can be made. Aim To systematically scope the literature on point of care US use in small bowel Crohn’s disease, generating a comprehensive list of factors relating to the current understanding of clinical utility of this imaging modality. Methods Searches included MEDLINE, EMBASE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, clinicaltrial.gov,‘TRIP’ and Epistemonikos. Reference lists of included studies were hand searched. Search terms were searched for as both keywords and subject headings (MeSH) as appropriate. Searches were performed with the ‘suggested search terms’ and ‘explode’ selection, and restricted to ‘human’, ‘adult’ and ‘English language’ publications. No date limits were applied to be as inclusive as possible. Two investigators conducted abstract and full-text review. No formal quality appraisal process was undertaken; however, quality of sources was considered when reporting findings. A narrative synthesis was conducted. Results The review included 42 sources from the UK, Europe, Japan, Canada and the USA. Small bowel ultrasound (SBUS) has been shown to be as accurate in detecting the presence of small bowel Crohn’s disease, is quicker, safer and more acceptable to patients, compared with magnetic resonance enterography. SBUS is used widely in central Europe and Canada but has not been embraced in the UK. Further research considering economic evaluation, clinical decision-making and exploration of perceived barriers to future implementation of SBUSs is required. All data relevant to the study are included in the article or uploaded as supplementary information.

成人克罗恩病小肠超声评估的临床效用：系统范围审查

背景超声 (US) 是磁共振肠造影的替代方法，具有显着减少等待时间、加快临床决策和改善患者体验的潜力。医疗点 US 是 US 成像模式的一个优势，可以在同一天进行扫描、解读和治疗决策。目的 系统地研究美国在小肠克罗恩病中使用的即时护理文献，生成与当前对该成像方式的临床效用的理解相关的因素的综合列表。方法搜索包括 MEDLINE、EMBASE、Cochrane 图书馆、护理和联合健康文献累积索引、PsycINFO、clinicaltrial.gov、'TRIP' 和 Epistemonikos。手动检索了纳入研究的参考文献列表。搜索词作为关键字和主题词 (MeSH) 酌情进行搜索。使用“建议的搜索词”和“爆炸”选择进行搜索，并仅限于“人类”、“成人”和“英语”出版物。没有应用日期限制以尽可能地具有包容性。两名研究人员进行了摘要和全文审查。没有进行正式的质量评估过程；然而，在报告调查结果时考虑了来源的质量。进行了叙述性综合。结果 审查包括来自英国、欧洲、日本、加拿大和美国的 42 个来源。与磁共振小肠造影相比，小肠超声 (SBUS) 已被证明在检测小肠克罗恩病方面同样准确，并且更快、更安全且更容易被患者接受。SBUS 在中欧和加拿大广泛使用，但在英国尚未普及。需要进一步研究考虑经济评估、临床决策和探索未来实施 SBUS 的感知障碍。所有与研究相关的数据都包含在文章中或作为补充信息上传。
