Abstract:

CASE HISTORY: Over a 3-year period between July 2008 and July 2011, 10 exploratory laparotomies were performed on foals in a Waikato referral facility in New Zealand.

CLINICAL FINDINGS: Right dorsal displacement of the large colon (RDDLC) was identified during four exploratory laparotomies in three foals that presented for mild-to-moderate colic that was non-responsive to medical management. One foal required a repeat laparotomy 7 weeks post initial surgery, and RDDLC was again diagnosed.

DIAGNOSIS: Right dorsal displacement of the large colon in foals.

CLINICAL RELEVANCE: Further investigation may identify risk factors or management practices contributing to this condition. This is an important and uncommonly reported cause of surgical colic in foals, that is also important to consider in non-responsive medical colic cases that do not appear to be associated with severe pain, but may still require prompt surgical intervention to avoid a strangulating obstruction. The incidence of the condition in one Waikato referral facility appears higher than what could be expected based on the current literature.
