Urinary catheters were placed to measure intra-abdominal pressure (IAP). A single access port was placed to establish a pneumorectum. Cadavers were placed in insufflation groups of 6 mmHg to 8 mmHg (group 1), 10 mmHg to 12 mmHg (group 2), or 14 mmHg to 16 mmHg (group 3). Defects in the rectal submucosa were created and closed with a unidirectional barbed suture. Duration for each procedure and subjective ease of identifying the transection plane and performing incisional closure were assessed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a4\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>The single access port was successfully placed in dogs weighing 22.7 kg to 48 kg. The ease of each step of the procedure was not influenced by the insufflation pressure. The median surgical duration for group 1 was 740 seconds (range = 564 to 951 seconds), 879 seconds (range = 678 to 991 seconds) for group 2, and 749 seconds (range = 630 to 1,244 seconds) for group 3 (<jats:italic>P<\/jats:italic> = .650). The insufflation pressure increased the IAP (<jats:italic>P<\/jats:italic> = .007). Perforation of the rectum happened in 2 cadavers in group 3.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a5\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>The duration of each step of the procedure was not significantly influenced by insufflation pressure. Defining the dissection plane and performing resection was more challenging in the highest-pressure group. Rectal perforation occurred only with the 14 mmHg to 16 mmHg insufflation pressure. Single access port usage with TAMIS may provide a readily available, minimally invasive approach for the resection of rectal tumors in dogs.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.23.02.0033","type":"journal-article","created":{"date-parts":[[2023,5,23]],"date-time":"2023-05-23T13:26:38Z","timestamp":1684848398000},"page":"1-7","source":"Crossref","is-referenced-by-count":0,"title":["Effect of insufflation pressure during transanal minimally invasive surgery on surgical complications with dissection of the rectal submucosa in canine cadavers"],"prefix":"10.2460","author":[{"given":"Diane M.","family":"Scavelli","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Monnet","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"B1","series-title":"JSAP","first-page":"423","article-title":"Transanal endoscopic treatment of benign canine rectal tumours: preliminary results in six cases (1992 to 1996)","volume":"40","author":"Holt PE","year":"1999","unstructured":"Holt PE, Durdey P.
