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.
在本病例报告中，我们介绍了一例 10 月龄阿拉伯母驹左侧结肠围绕肠系膜根部顺时针扭转的罕见病例，重点介绍了其临床特征、诊断方法和成功的手术干预。
10 月龄、体重约 250kg 的阿拉伯母驹因急性腹痛就诊。其病史显示，前一天出现食欲减退、不安和严重腹痛。当地兽医曾给予氟尼辛葡甲胺（一种镇痛药），但未能缓解疼痛。
临床检查时，该驹表现为出汗、体温 38.5°C、心动过速（65 次/分钟）和呼吸急促（25 次/分钟）。由于腹痛严重且保守治疗无效，因此认为有必要进行手术干预。
实施了正中剖腹探查术，以评估腹部器官。检查过程中，未发现评估器官有明显原发性病变，但发现左侧结肠长度向外伸展受限。进一步检查发现，左侧结肠发生了异常顺时针扭转，围绕肠系膜根部向左至右侧移位；因此，骨盆曲度位于正常解剖位置，但长度较短。据我们所知，这是首例报道的马属动物顺时针扭转和左侧结肠异常移位的病例。成功实施了移位的矫正手术。术后该驹情况改善，恢复期未出现任何并发症。
