Unusual left colon displacement and clockwise torsion in a 10‐month‐old Arab filly: A case report

Abstract

In this case report, we present an unusual clockwise torsion of left colon around mesenteric root in a 10‐month‐old Arab filly, highlighting the clinical presentation, diagnostic approach and successful surgical intervention. A 10‐month‐old Arab filly weighing approximately 250 kg was referred with signs of acute abdominal pain. The history revealed anorexia, restlessness and severe abdominal pain that had begun the previous day. The local practitioner had previously administered flunixin meglumine, an analgesic, but it proved ineffective in relieving the pain. Upon physical examination, the filly exhibited sweating, a body temperature of 38.5°C, tachycardia (65 beats per minute) and tachypnea (25 breaths per minute). Due to the severity of the colic and the lack of response to the conservative treatments, surgical intervention was deemed necessary. An exploratory midline celiotomy was performed to evaluate the abdominal organs. During the examination, no obvious primary lesions were identified in the evaluated organs. However, a restriction in exteriorizing the left colon's length was observed. Further examination revealed an unusual clockwise torsion of the left colon that displaced in left to the right side around the mesenteric root; thereby, pelvic flexure was located in the normal anatomical position with a short length. To the best of our knowledge, this is the first reported case of clockwise torsion and an atypical displacement of the left colon in horses. The surgical correction of the displacement was successfully performed. The filly showed improvement post‐surgery and did not exhibit any complications during the recovery period.
