While barrier agents are widely used for prevention, current solutions often suffer from limited efficacy and short retention times. This study evaluates the dual\u2010functionality of a polysaccharide\u2010based medical device, 4SEAL Hemostatic Powder, by evaluating hemostatic performance and the reduction of postoperative adhesions. Using rat models, the hemostatic efficacy of 4SEAL was assessed via a standardized liver incision protocol, while its anti\u2010adhesive properties were compared to hyaluronic acid and saline controls following ovariohysterectomy. Outcomes measured included time to hemostasis, number and severity of adhesions, and comprehensive histological, hematological, biochemical, and metabolic analyses to assess safety and tissue response. In addition, the absorption profile of 4SEAL, in both gel and powder forms, was evaluated using a murine model. 4SEAL Hemostatic Powder significantly shortened time to hemostasis (2.14\u00b10.39\u00a0min vs. 4.30\u00b12.02\u00a0min for untreated controls,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.003) and decreased both the number of adhesions (powder: 0.85\u00b10.75, gel: 1.0\u00b10.92\u00a0vs. 2.9\u00b11.29 for controls,\n                    <jats:italic>p<\/jats:italic>\n                    &lt;0.01) and adhesion severity (powder: 3.75\u00b12.67, gel: 3.55\u00b13.19\u00a0vs. 7.7\u00b14.88 for controls,\n                    <jats:italic>p<\/jats:italic>\n                    &lt;0.05). Hyaluronic acid reduced adhesion number (1.6\u00b12.27,\n                    <jats:italic>p<\/jats:italic>\n                    &lt;0.05) but not severity (4.8\u00b14.44, not statistically significant). Histological analysis indicated more advanced tissue regeneration and lower levels of fibrosis in 4SEAL\u2010treated animals. No significant systemic biochemical or metabolic alterations were observed in the 4SEAL groups, supporting its biocompatibility. The findings indicate that 4SEAL Hemostatic Powder is effective in promoting hemostasis and reducing postoperative adhesion formation in preclinical models. The material demonstrated biocompatibility and biodegradability, supporting its potential utility as a dual\u2010function surgical adjunct.\n                  <\/jats:p>","DOI":"10.1002\/mabi.202500664","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T10:12:08Z","timestamp":1774606328000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dual\u2010Functionality of Polysaccharide\u2010based Hemostatic Powder: Effective Bleeding Control and Adhesion Reduction in Surgical Models"],"prefix":"10.1002","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0148-541X","authenticated-orcid":false,"given":"Lukasz","family":"Szymanski","sequence":"first","affiliation":[{"name":"Department of Molecular Biology Institute of Genetics and Animal Biotechnology Polish Academy of Sciences  Magdalenka Poland"},{"name":"European Biomedical Institute  Warsaw Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrycja","family":"Krakowiak","sequence":"additional","affiliation":[{"name":"European Biomedical Institute  Warsaw Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zuzanna","family":"Walas","sequence":"additional","affiliation":[{"name":"European Biomedical Institute  Warsaw Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Izabela","family":"Szubarczyk","sequence":"additional","affiliation":[{"name":"European Biomedical Institute  Warsaw Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damian","family":"Matak","sequence":"additional","affiliation":[{"name":"European Biomedical Institute  Warsaw Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,3,27]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm12062263"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1159\/000314805"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.5114\/pg.2022.118454"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365\u20102168.1998.00841.x"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.21626\/innova\/2016.2\/01"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0276810"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijbiomac.2025.139557"},{"key":"e_1_2_9_9_1","article-title":"Transparency in the Reporting of Artificial Intelligence \u2013 The TITAN Guideline","volume":"10","author":"Agha R.
