Use of a new device for inversion of the necrotic ileal stump in the caecum in four horses.

BACKGROUND

In jejunocaecal anastomosis leaving a necrotic ileal stump has been implicated in complications and poor outcomes. Elective inversion of the necrotic stump using a nasogastric tube has been previously described, although this procedure can be cumbersome and can cause caecocolic orifice occlusion.

OBJECTIVE

To describe the use of a new device for elective inversion of necrotic ileal stumps.

STUDY

DESIGN

Case report.

METHODS

Details of the four horses that underwent intestinal resection and anastomosis with elective inversion of the ileal stump were retrieved from their medical records. For each case, a device was constructed by securing 0.7 m of hemp tape to a 0.5 m long electrical cable puller. The device was inserted into the ileum and passed through the caecum. The ileal lumen was closed using sutures or staples, and the tape was simultaneously secured to the intestine. The ileum was then resected. A small typhlotomy was performed at the proposed site for jejunocaecal anastomosis. The device was retrieved, the hemp tape was cut, and jejunocaecal anastomosis was completed.

RESULTS

The device was easily secured to the intestines. Small enterotomies were sufficient for device insertion and removal. In four clinical cases the procedure was effective in inverting the stump, and three out of the four horses recovered uneventfully and were discharged from the hospital. One horse was euthanised due to colic 27 months following discharge.

MAIN LIMITATIONS: Small number of cases admitted to single tertiary hospital.

CONCLUSIONS

The device was effective in inverting the ileal stump in the included clinical cases. By leaving a short, inverted stump, this method may help improve the prognosis for jejunocaecal anastomosis, possibly avoiding certain undesired effects of the procedure. Further studies with large numbers of cases are required.
