As surgical education and technology moves toward improving patient outcomes through automation and increasing training opportunities, a detailed characterization of the interventional biomechanical properties of the human bowel is important. This is especially true due to the prevalence of anastomotic leakage as a frequent (3.02%) postoperative complication of small bowel anastomoses. This study aims to characterize the forces required for a suture to tear through human small bowel (suture pullout force, SPOF), while analyzing how these forces are affected by tissue orientation, suture material, suture size, and donor demographics. 803 tests were performed on 35 human small bowel specimens. A uni-axial test frame was used to tension sutures looped through 10\u2009\u00d7\u200920\u2009mm rectangular bowel samples to tissue failure. The mean SPOF of the small bowel was 4.62\u00b11.40\u2009N. We found no significant effect of tissue orientation (p\u2009=\u20090.083), suture material (p\u2009=\u20090.681), suture size (p\u2009=\u20090.131), age (p\u2009=\u20090.158), sex (p\u2009=\u2009.083), or body mass index (BMI) (p\u2009=\u20090.100) on SPOF. To our knowledge, this is the first study reporting human small bowel SPOF. Little research has been published about procedure-specific data on human small bowel. Filling this gap in research will inform the design of more accurate human bowel synthetic models and provide an accurate baseline for training and clinical applications.<\/jats:p>","DOI":"10.1115\/1.4063951","type":"journal-article","created":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T13:34:42Z","timestamp":1698932082000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":2,"title":["Characterizing the Suture Pullout Force for Human Small Bowel"],"prefix":"10.1115","volume":"146","author":[{"given":"Alex T.","family":"Gong","sequence":"first","affiliation":[{"name":"Department of Surgery, University of Washington , 1959 NE Pacific Ave, Magnuson Health Sciences T293, Seattle, WA 98195-0000"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shi-Wen Olivia","family":"Yau","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of Washington , 1959 NE Pacific Ave Magnuson Health Sciences T293, Seattle, WA 98195-0000 ;
