Endoscopy has advanced significantly in recent years, including both detection technology as well as treatment options. For the lower gastrointestinal tract, current guidelines do not provide clear recommendations for surveillance intervals. Furthermore, the Spigelman staging system for duodenal polyposis has its limitations. We present a newly developed personalized endoscopic surveillance strategy for the lower and upper gastrointestinal tract, aiming to improve the care for patients with FAP. We aim to inform centers caring for FAP patients and encourage the discussion on optimizing endoscopic surveillance and treatment in this high-risk population. <\/jats:p><jats:p>\n          Methods\u2002The European FAP Consortium, consisting of endoscopists with expertise in FAP, collaboratively developed new surveillance protocols. The proposed strategy was consensus-based and a result of several consortium meetings, discussing current evidence and limitations of existing systems. This strategy provides clear indications for endoscopic polypectomy in the rectum, pouch, duodenum and stomach and defines new criteria for surveillance intervals. This strategy will be evaluated in a 5-year prospective study in nine FAP expert centers in Europe.<\/jats:p><jats:p>\n          Results\u2002We present a newly developed personalized endoscopic surveillance and endoscopic treatment strategy for patients with FAP aiming to prevent cancer, optimize endoscopic resources and limit the number of surgical interventions. Following this new strategy, prospectively collected data in a large cohort of patients will inform us on the efficacy and safety of the proposed approaches.<\/jats:p>","DOI":"10.1055\/a-2011-1933","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T00:02:20Z","timestamp":1673481740000},"page":"E386-E393","source":"Crossref","is-referenced-by-count":23,"title":["Personalized endoscopic surveillance and intervention protocols for patients with familial adenomatous polyposis: the European FAP Consortium strategy"],"prefix":"10.1055","volume":"11","clinical-trial-number":[{"clinical-trial-number":"nct04678011","registry":"10.18810\/clinical-trials-gov"},{"clinical-trial-number":"nct04677998","registry":"10.18810\/clinical-trials-gov"}],"author":[{"given":"Arthur S.","family":"Aelvoet","sequence":"additional","affiliation":[{"name":"Amsterdam UMC location University of Amsterdam, Department of Gastroenterology and Hepatology, Amsterdam, the Netherlands"},{"name":"Cancer Center Amsterdam, Amsterdam, the Netherlands"},{"name":"Amsterdam Gastroenterology Endocrinology Metabolism, Amsterdam, the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Pellis\u00e9","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Hospital Cl\u00ednic de Barcelona, Institut d\u02bcInvestigacions Biom\u00e8diques August Pi i Sunyer (IDIBAPS), Centro de Investigaci\u00f3n Biom\u00e9dica en Red de Enfermedades Hep\u00e1ticas y Digestivas (CIBEREHD), University of Barcelona, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara A.J.","family":"Bastiaansen","sequence":"additional","affiliation":[{"name":"Amsterdam UMC location University of Amsterdam, Department of Gastroenterology and Hepatology, Amsterdam, the Netherlands"},{"name":"Cancer Center Amsterdam, Amsterdam, the Netherlands"},{"name":"Amsterdam Gastroenterology Endocrinology Metabolism, Amsterdam, the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monique E.","family":"van Leerdam","sequence":"additional","affiliation":[{"name":"Department of Gastrointestinal Oncology, Netherlands Cancer Institute, Amsterdam, the Netherlands"},{"name":"Department of Gastroenterology and Hepatology, Leiden University Medical Center, Leiden, the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo","family":"Jover","sequence":"additional","affiliation":[{"name":"Servicio de Medicina Digestiva, Hospital General Universitario de Alicante, Instituto de Investigaci\u00f3n Biom\u00e9dica ISABIAL, Universidad Miguel Hern\u00e1ndez, Alicante, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesc","family":"Balaguer","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Hospital Cl\u00ednic de Barcelona, Institut d\u02bcInvestigacions Biom\u00e8diques August Pi i Sunyer (IDIBAPS), Centro de Investigaci\u00f3n Biom\u00e9dica en Red de Enfermedades Hep\u00e1ticas y Digestivas (CIBEREHD), University of Barcelona, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal F.","family":"Kaminski","sequence":"additional","affiliation":[{"name":"Department of Oncological Gastroenterology and Department of Cancer Prevention, Maria Sklodowska-Curie National Research Institute of Oncology, Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John G.","family":"Karstensen","sequence":"additional","affiliation":[{"name":"Danish Polyposis Registry.
