During a 28 month period, 82 horses with clinical signs of abdominal pain were examined for left dorsal displacement of the large colon (LDDLC) using percutaneous ultrasound. Left dorsal displacement of the large colon was diagnosed when a gas echo dorsal to the spleen obliterated the dorsal splenic border, or when the colon was observed lateral to the spleen. In 42 horses, ultrasound confirmed a diagnosis of LDDLC and 40 horses had no evidence of LDDLC. There were five false negative results and no false positives. In four horses with LDDLC, the colon was displaced between the spleen and body wall; three of these colic episodes resolved with medical therapy and the fourth required a celiotomy to relieve a sand impaction. The remaining 38 horses had a renosplenic entrapment; surgical correction was elected in 4 horses, 21 horses were corrected by a nonsurgical rolling procedure, 12 were corrected at surgery after an unsuccessful rolling attempt, and one was corrected by rolling but required surgery later because of an additional lesion. Percutaneous abdominal ultrasound was a valuable aid in the diagnosis of LDDLC and in confirming correction of the displacement after a nonsurgical rolling procedure.
在28个月的时间里，对82匹有腹痛临床症状的马匹进行经皮超声检查，以诊断大结肠左背侧移位（LDDLC）。当脾脏背侧的气体回声使脾脏背侧边界消失，或在脾脏外侧观察到结肠时，诊断为大结肠左背侧移位。42匹马经超声确诊为LDDLC，40匹马没有LDDLC的证据。有5例假阴性结果，无假阳性结果。4匹患有LDDLC的马，结肠移位至脾脏与体壁之间；其中3例绞痛发作经药物治疗缓解，第4例需要剖腹手术以解除沙粒阻塞。其余38匹马存在肾脾嵌顿；4匹马选择手术矫正，21匹马通过非手术翻滚程序矫正，12匹马在翻滚尝试失败后接受手术矫正，1匹马通过翻滚矫正，但后来因另发病变而需要手术。经皮腹部超声在LDDLC的诊断以及确认非手术翻滚程序后移位的矫正方面是一种有价值的辅助手段。
