The guideline addresses diet and preparation instructions, including the use of enhanced patient guidance, addition of oral simethicone, and selection of PEG-based or non-PEG validated regimens. It emphasizes split-dose preparation, timing of the final dose within 5 hours before colonoscopy and completion at least 2 hours prior, and individualized laxative choice for patients at risk of hydroelectrolyte disturbances. Scope and rationale are linked to improved cleansing accuracy, higher adenoma detection, and better patient experience.",{"@graph":69,"@context":123},[70,84,106],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":35,"@type":76,"position":81},"https://docshare.wps.com/document/healthcare/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/bowel-preparation-for-colonoscopy-european-society-of-gastrointestinal-endoscopy-esge-guideline-update-2019/402480/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/bowel-preparation-for-colonoscopy-european-society-of-gastrointestinal-endoscopy-esge-guideline-update-2019/402480.png","ImageObject",300,407,{"name":92,"@type":93},"Noah","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-01","2026-09-27",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",14,{"@type":107,"mainEntity":108},"FAQPage",[109,115,119],{"name":110,"@type":111,"acceptedAnswer":112},"What does ESGE recommend for diet the day before colonoscopy?","Question",{"text":113,"@type":114},"ESGE recommends a low fiber diet on the day preceding colonoscopy.","Answer",{"name":116,"@type":111,"acceptedAnswer":117},"Which bowel preparation approach does ESGE recommend for elective colonoscopy?",{"text":118,"@type":114},"ESGE recommends split-dose bowel preparation for elective colonoscopy, supported by high-quality evidence.",{"name":120,"@type":111,"acceptedAnswer":121},"When should the last dose of bowel preparation be taken relative to colonoscopy?",{"text":122,"@type":114},"ESGE recommends starting the last dose within 5 hours of colonoscopy and completing it at least 2 hours before the procedure begins.","https://schema.org",{"og:url":83,"og:type":125,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":127,"canonical":83},"index,follow",{"doc_id":129,"site_id":62},402480,1790673951,{"code":4,"msg":5,"data":132},{"doc_id":129,"user_id":133,"nickname":92,"user_avatar":134,"doc_module":4,"category_id":34,"category_name":35,"doc_title":65,"doc_description":67,"doc_content":135,"file_id":136,"file_url":137,"file_type":138,"file_size":139,"view_count":105,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":46,"language":140,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":67,"update_tm":144,"read_time":31,"preview_page_count":4},8796095462418,"https://ap-avatar.wpscdn.com/avatar/80000253c1241d02b47?x-image-process=image/resize,m_fixed,w_180,h_180&k=1778826106357471780","Bowel preparation for colonoscopy: European Society of Gastrointestinal Endoscopy (ESGE) Guideline – Update 2019  \nAuthors  \nCesare Hassan1, James East2, Franco Radaelli3, Cristiano Spada4, Robert Benamouzig5, Raf Bisschops6, Michael Bretthauer7, E.
