Data collection included perioperative and surgical variables, complications, outcome, and owner perception of the procedure.

The median survival time was not reached. Cats with (vs without) a body condition score &lt; 4\/9 (hazard ratio [HR], 5.97), preexisting heart disease (HR, 3.21), major perioperative complications (HR, 27.8), or long-term postoperative liquid feces (HR, 10.4) had greater hazard of shorter survival time. Constipation recurrence occurred in 32% (24\/74) of cats at a median time of 344 days and was not associated with retention versus removal of the ICJ; however, ICJ removal was associated with long-term liquid feces (OR, 3.45), and a fair or poor outcome on owner assessment (OR, 3.6).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s005\">\n<jats:title>CONCLUSIONS AND CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Results indicated that subtotal colectomy was associated with long survival times and a high rate of owner satisfaction.
