Treatment in these patients remains challenging and the process of physiologic adaptation may take years to complete, which frequently requires parenteral nutrition. We propose a proof-of-concept mechanical bowel elongation approach using a self-expanding prototype of an intestinal expansion sleeve (IES) for use in SBS to accelerate the adaptation process. Methods: IESs were deployed in the small intestines of Sprague Dawley rats. Mechanical characterization of these prototypes was performed. IES length\u2013tension relationships and post-implant bowel expansion were measured ex vivo. Bowel histology before and after implantation was evaluated. Results: IES mechanical studies demonstrated decreasing expansive force with elongation. The deployment of IES devices produced an immediate 21 \u00b1 8% increase in bowel length (p &lt; 0.001, n = 11). Mechanical load testing data showed that the IESs expressed maximum expansive forces at 50% compression of the initial pre-contracted length. The small-intestine failure load in the rats was 1.88 \u00b1 21 N. Intestinal histology post deployment of the IES showed significant expansive changes compared to unstretched bowel tissue. Conclusions: IES devices were scalable to the rat intestinal model in our study. The failure load of the rat small intestine was many times higher than the force exerted by the contraction of the IES. Histology demonstrated preservation of intestinal structure with some mucosal erosion. Future in vivo rat studies on distraction enterogenesis with this IES should help to define this organogenesis phenomenon.<\/jats:p>","DOI":"10.3390\/pathophysiology31030029","type":"journal-article","created":{"date-parts":[[2024,8,1]],"date-time":"2024-08-01T18:04:59Z","timestamp":1722535499000},"page":"388-397","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Distraction Enterogenesis in Rats: A Novel Approach for the Treatment of Short Bowel Syndrome"],"prefix":"10.3390","volume":"31","author":[{"given":"Collyn","family":"O\u2019Quin","sequence":"first","affiliation":[{"name":"Department of Surgery, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean D.","family":"Clayton","sequence":"additional","affiliation":[{"name":"Department of Surgery, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lexus","family":"Trosclair","sequence":"additional","affiliation":[{"name":"Department of Surgery, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7041-1095","authenticated-orcid":false,"given":"Hannah","family":"Meyer","sequence":"additional","affiliation":[{"name":"Department of Surgery, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nhi H.","family":"Dao","sequence":"additional","affiliation":[{"name":"Department of Molecular and Cellular Physiology, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Minagar","sequence":"additional","affiliation":[{"name":"Department of Molecular and Cellular Physiology, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luke","family":"White","sequence":"additional","affiliation":[{"name":"Department of Molecular and Cellular Physiology, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valerie","family":"Welch","sequence":"additional","affiliation":[{"name":"Department of Pathology, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0994-5724","authenticated-orcid":false,"given":"Giovanni","family":"Solitro","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6975-3711","authenticated-orcid":false,"given":"Jonathan Steven","family":"Alexander","sequence":"additional","affiliation":[{"name":"Department of Molecular and Cellular Physiology, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald","family":"Sorrells","sequence":"additional","affiliation":[{"name":"Department of Surgery, LSU Health Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,30]]},"reference":[{"key":"ref_1","unstructured":"Guillen, B., and Atherton, N.S.
