Gastrointestinal disorders are among the most common disease processes in captive elephants. Colic is a frequent clinical presentation and may have several infectious and noninfectious causes. Ingestion of sand has been reported in elephants living in enclosures with loose sandy soils. Similar to the situation in horses, sand ingestion can cause intestinal impaction and colic in elephants. Here we describe a case of colonic sand impaction with cecal rupture and peritonitis in an African savanna elephant from a zoologic collection that died after several days of colic. On autopsy, abundant, gritty, sandy material was found within a segment of colon immediately aboral to the cecum. There was a full-thickness tear in the cecal wall, free intestinal contents within the abdominal cavity, and peritonitis. To our knowledge, the postmortem examination of an elephant with sand impaction and cecal rupture has not been reported previously; this condition should be included among the differential diagnoses in elephants with colic. We review the reports of noninfectious causes of gastrointestinal disease in elephants, which include cases of small intestinal and colonic torsion and of intestinal obstruction by fecal boluses.
胃肠道疾病是圈养大象中最常见的疾病之一。腹痛是一种常见的临床表现,可能有几个感染和非感染的原因。在有松散沙土的围栏中生活的大象会摄入沙子。与马的情况类似,大象摄入沙子会导致肠内嵌塞和腹痛。在这里,我们描述了一个来自动物园的非洲热带草原象的结肠沙嵌塞病例,该象在腹痛数日后死亡。尸检时,在靠近盲肠的一段结肠内发现了大量粗糙的沙质物质。盲肠壁有全层撕裂,腹腔内有游离肠内容物和腹膜炎。据我们所知,以前没有报道过因沙嵌塞和盲肠破裂导致的大象尸检;这种情况应作为腹痛大象的鉴别诊断之一。我们回顾了大象非传染性胃肠道疾病的报告,包括小肠和结肠扭转以及粪便块引起的肠梗阻的病例。
