Miller et al: Cooled feline intestine and fresh intestine did not differ in enterotomy leak pressure testing or in gross wall thickness measurement
Veterinary Surgery 5, 2024

🔍 Key Findings

• No difference in initial leak pressure (ILP) or maximum intraluminal pressure (MIP) between cooled (17–29 h) and fresh enterotomy constructs.
• Wall thickness of duodenum and jejunum did not differ between fresh and cooled samples.
• Leak locations (suture holes vs clamp sites) were similar between groups; not statistically different.
• Volume of infusion did not influence ILP or MIP outcomes.
• Mean ILP values: Control = 600 mmHg (maxed), Fresh = 200 mmHg, Cooled = 131 mmHg; CE vs FE difference was not significant.
• Intraluminal diameter was largest in the ileum, followed by jejunum and duodenum.
• Cadaveric intestine cooled ≤29h may be reliably used in ex vivo feline leak pressure studies.
• First report of gross small intestinal lengths by region in cats—useful for resection planning.
