Medical records of 48 equids (47 horses, 1 pony) with surgical sand colic were reviewed. The diagnosis of sand colic was made if a sand impaction(s) was palpated during exploratory abdominal surgery or if a large quantity of sand was found during colotomy. Most equids did not experience a previous episode of sand diarrhea or sand colic. Clinical findings and results of clinicopathologic determinations were not diagnostic. Rectal palpation findings in 40 of 46 horses were compatible with large-colon and/or cecal distention. Impactions were palpable per rectum in only 7 horses, but emergency abdominal surgery revealed one or more impactions in 46 of 48 equids. Single impaction most commonly was observed at the pelvic flexure. Twenty-six horses had concurrent large-colon torsion or displacement. Pelvic flexure colotomy was performed in 44 horses. Of 48 equids, 44 survived and were discharged.
回顾了48例患有外科性沙积腹痛的马属动物（47匹马，1匹小马）的病历。如果在剖腹探查术中触诊到沙性阻塞，或者在结肠切开术中发现大量沙子，则诊断为沙积腹痛。大多数马属动物既往没有沙性腹泻或沙积腹痛发作史。临床检查结果和临床病理检查结果均无诊断意义。46匹马中有40匹马的直肠触诊结果与大结肠和/或盲肠扩张相符。仅7匹马经直肠可触及阻塞，但急诊腹部手术显示48例马属动物中有46例存在一处或多处阻塞。最常见的单个阻塞位于骨盆曲。26匹马同时存在大结肠扭转或移位。44匹马接受了骨盆曲结肠切开术。48例马属动物中，44例存活并出院。
