Dehiscence and enterotomy leakage are potentially devastating complications in patients that have undergone gastrointestinal surgery.1,2 In vitro bursting pressure testing has been reported as a useful method for evaluation of enterotomy techniques3–5 and has the advantage of the relative ease of detection of enterotomy failure at bursting pressure. However, this technique cannot be performed in vivo. In situ bursting pressure testing may offer several advantages over in vitro testing: the intestinal segment does not need to be harvested prior to testing, and this experimental technique could potentially be used in live animals that will be recovered from surgery.
The objective of the study reported here was to compare bursting pressures in canine jejunum, measured by use of an in vitro and an in situ bursting pressure technique. Our hypothesis was that an in situ bursting pressure technique would yield bursting pressures similar to those for an in vitro bursting pressure technique.
