While most patients will develop ulceration, it can be difficult to determine whether the ulceration represents a true Crohn\u2019s recurrence. Scoring systems such as the Rutgeerts Score and modified Rutgeerts score can help differentiate between disease that may have higher risk for progression. Risk factors such as tobacco use, penetrating phenotype, and prior surgical resection have been identified, in addition to surgical technique. Recent evidence has supported certain surgical techniques, such as a side-to-side stapled technique and the Kono-S, to prevent post-surgical ulceration. Post-surgical prophylactic treatment with biologic therapies have the potential to reduce disease recurrence in certain patients. Post-surgical ulceration at the ileocolonic anastomosis is a complex problem that requires careful surveillance and evidence-based management. Understanding which patients are at high risk for disease recurrence and progression is important to guide treatment.<\/jats:p>","DOI":"10.3390\/jcm14228158","type":"journal-article","created":{"date-parts":[[2025,11,19]],"date-time":"2025-11-19T12:55:31Z","timestamp":1763556931000},"page":"8158","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Recurrent Ulceration and Disease at the Ileocolonic Anastomosis in Crohn\u2019s Disease: Etiology, Prevention, and Management, a Review Article"],"prefix":"10.3390","volume":"14","author":[{"given":"Abigail","family":"Schubach","sequence":"first","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Northwell Health, Manhasset, NY 11040, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7619-2024","authenticated-orcid":false,"given":"Keith","family":"Sultan","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Northwell Health, Manhasset, NY 11040, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arun","family":"Swaminath","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Lenox Hill Hospital Northwell Health, New York, NY 10075, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"956","DOI":"10.1016\/0016-5085(90)90613-6","article-title":"Predictability of the postoperative course of Crohn\u2019s disease","volume":"99","author":"Rutgeerts","year":"1990","journal-title":"Gastroenterology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"996","DOI":"10.1053\/j.gastro.2013.07.041","article-title":"Risk of surgery for inflammatory bowel diseases has decreased over time: A systematic review and meta-analysis of population-based studies","volume":"145","author":"Frolkis","year":"2013","journal-title":"Gastroenterology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1274","DOI":"10.1111\/j.1572-0241.2006.00552.x","article-title":"Increasing Incidences of Inflammatory Bowel Disease and Decreasing Surgery Rates in Copenhagen City and County, 2003\u20132005: A Population-Based Study from the Danish Crohn Colitis Database","volume":"101","author":"Vind","year":"2006","journal-title":"Off.
