Comparison of Surgically Treated Large Versus Small Intestinal Volvulus (2009-2014).

Abstract

The purpose of this retrospective study was to compare the outcome for dogs with surgically treated large versus small intestinal volvulus between October 2009 and February 2014. A total of 15 dogs met the inclusion criteria and underwent an abdominal exploratory. Nine dogs were diagnosed with large intestinal volvulus during the study period, and all nine had surgical correction for large intestinal volvulus. All dogs were discharged from the hospital. Of the seven dogs available for phone follow-up (74 to 955 days postoperatively), all seven were alive and doing well. Six dogs were diagnosed with small intestinal volvulus during the study period. One of the six survived to hospital discharge. Three of the six were euthanized at the time of surgery due to an extensive amount of necrotic bowel. Of the three who were not, one died postoperatively the same day, one died 3 days later, and one dog survived for greater than 730 days. Results concluded that the outcome in dogs with surgically corrected large intestinal volvulus is excellent, compared with a poor outcome in dogs with small intestinal volvulus. The overall survival to discharge for large intestinal volvulus was 100%, versus 16% for small intestinal volvulus.
