A 200 L polyurethane bladder was inserted into the abdomen. Celiotomies were closed in a simple continuous pattern with 1 section of 7PD. The bladder was inflated with compressed air until construct failure. Horse signalment, body weight, celiotomy type, failure mode (suture or abdominal wall), failure location (adjacent or remote from the celiotomy), and bursting strength (mmHg) were recorded. Interactions between independent and dependent variables were assessed with statistical tests including linear regression.</p> </sec> <sec id="vsu12003-sec-0005" sec-type="section"> <title>Results</title> <p>Increasing age (<italic>P</italic> = .002) and Quarter horse‐type breed (<italic>P</italic> = .01) had a negative effect on bursting strength. When age and breed were controlled, RVP celiotomies had a lower bursting strength compared with VM celiotomies (<italic>P</italic> = .039).

Celiotomy bursting strength decreases with increasing age and is lower in Quarter horse‐type breeds compared with non‐Quarter horse‐type breeds.</p> </sec> </abstract>
