Oligomeric enteral formulas, designed to facilitate absorption in patients with compromised bowel function, have shown clinical efficacy, though their implementation lacks standardization due to the lack of uniform protocols. Objective: To establish a multidisciplinary consensus on the use of oligomeric formulas in patients with malabsorption using a Delphi methodology. Material and Method: A Delphi study was conducted with 156 specialists in endocrinology, gastroenterology, oncology, and internal medicine. Two rounds of structured surveys assessed clinical practices, associated symptoms, and the use of oligomeric enteral formulas. Data were analyzed using descriptive statistics and non-parametric tests, defining consensus with a median of \u22657 and an interquartile range of \u22643. Likewise, a Median (MED) score of \u22643 was considered as a consensus to reject the statement, while an Interquartile range (IQR) of \u22654 or a MED of 4\u20136 was considered as no agreement. These statements were reviewed and included in the second round. Results: Screening for malnutrition is widely supported (79%), but only 38% of participants reported having specific management protocols. Symptoms such as abdominal distension, abdominal pain, and diarrhea were identified as key predictors of intolerance to polymeric formulas, establishing oligomeric enteral formulas as first choice in these cases. In addition, the effectiveness of an approach that progresses from oligomeric to polymeric enteral formulas once symptoms have stabilized was highlighted. The need for standardized protocols was recognized as a priority to guide nutritional assessment and treatment in patients with malabsorption. Conclusions: This consensus reinforces the importance of implementing specific clinical protocols for the nutritional management of malabsorption, including the initial use of oligomeric enteral formulas in patients with severe symptoms and their controlled transition to polymeric enteral formulas.<\/jats:p>","DOI":"10.3390\/nu17091426","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T08:08:41Z","timestamp":1745482121000},"page":"1426","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Use of Oligomeric Formulas in Malabsorption: A Delphi Study and Consensus"],"prefix":"10.3390","volume":"17","author":[{"given":"Carmelo","family":"Di\u00e9guez Castillo","sequence":"first","affiliation":[{"name":"Specialist in Gastroenterology, Hospital Universitario Torrec\u00e1rdenas, 04009 Almer\u00eda, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Sidahi Serrano","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Infanta Elena Hospital, 21007 Huelva, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Mart\u00edn Aguilar","sequence":"additional","affiliation":[{"name":"Medical Department, Abbott Laboratories, 28050 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1745-9315","authenticated-orcid":false,"given":"Daniel","family":"De Luis Rom\u00e1n","sequence":"additional","affiliation":[{"name":"Center of Investigation Endocrinology and Nutrition, Valladolid University Clinical Hospital, Medicine School University, 47002 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1007\/s11894-020-00771-5","article-title":"Maldigestion Versus Malabsorption in the Elderly","volume":"22","author":"Schiller","year":"2020","journal-title":"Curr.
