Five portal configurations were compared: a smooth (S) and threaded (T) cannula with and without a Rumel suture (SR and TR, respectively) and a balloon (B) cannula. Each configuration was inserted once each on midline and paramedian, the abdomen was insufflated to 10 mm Hg, and the cannula was manipulated for 2 minutes. Gas leakage was recorded by using a soap bubble test and the duration of insufflation (seconds).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sc_a3\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Regardless of location, SR and TR had the fewest number of leaks and duration of insufflation. When comparing midline portal locations, there were no demonstrable differences in duration of insufflation between portal configurations. When comparing the estimated difference in duration of insufflation for paramedian portal locations, SR had a lower duration of insufflation compared to T by 67.0 seconds and S by 46.2 seconds, and TR had a lower duration of insufflation compared to T by 66.5 seconds and S by 45.7 seconds. Between midline and paramedian, the S configuration had a statistically significant decrease in duration of insufflation on midline compared to paramedian by 30.4 seconds. The T configuration had a significantly lower duration of insufflation on midline compared to paramedian by 51.1 seconds.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sc_a4\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Gas leakage varies between portals, and adding a Rumel suture decreased gas leakage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sc_a5\">\n                    <jats:title>Clinical Relevance<\/jats:title>\n                    <jats:p>Surrounding stainless steel entry portals with a Rumel suture could help minimize insufflation leakage of the cannula.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2460\/ajvr.25.04.0142","type":"journal-article","created":{"date-parts":[[2025,8,12]],"date-time":"2025-08-12T12:28:11Z","timestamp":1755001691000},"source":"Crossref","is-referenced-by-count":0,"title":["The addition of a Rumel suture minimizes entry portal gas leakage of laparoscopic ports: a canine cadaveric study"],"prefix":"10.2460","volume":"86","author":[{"given":"Erica","family":"Rehnblom","sequence":"first","affiliation":[{"name":"Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Iowa State University, Ames, IA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrien","family":"Aertsens","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Iowa State University, Ames, IA"},{"name":"Surgery Department, Centre Hospitalier V\u00e9t\u00e9rinaire Aquivet, M\u00e9rignac, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"B1","series-title":"Advanced Gynecologic Endoscopy","first-page":"89","article-title":"Chapter 6: laparoscopic access techniques","author":"Norbert M","year":"2011","unstructured":"Norbert M, Lorenc Z, Starzewski J.
