Fatal colonic obstructions were diagnosed in three captive, adult, reticulated giraffe (Giraffa camelopardalis reticulata). Clinical presentations varied, but all cases displayed decreased activity, anorexia, and considerably decreased fecal production, consistent with intestinal obstruction. Case 1 was diagnosed at necropsy with a phytobezoar obstructing the spiral colon. Case 2 was diagnosed at necropsy with a fecal impaction of the colon. Case 3 was diagnosed during surgery with colonic ileus. Cases 2 and 3 underwent surgical intervention but were markedly compromised by the time of surgery and died during surgery or 24 hr postoperatively. Gastrointestinal obstruction, requiring aggressive supportive care and early surgical intervention, should be considered in giraffe in which anorexia and substantially decreased fecal production are observed. Abdominal exploratory surgery will likely be necessary for diagnosis and treatment. Based on a small number of cases, gastrointestinal obstruction has a poor prognosis in giraffe.
在三只圈养的成年网纹长颈鹿（Giraffa camelopardalis reticulata）中诊断出致命性结肠梗阻。临床表现各不相同，但所有病例均表现为活动减少、食欲不振和粪便产量大幅下降，这与肠梗阻相符。病例1在尸检时诊断为植物性胃石阻塞螺旋结肠。病例2在尸检时诊断为结肠粪便嵌塞。病例3在手术中诊断为结肠麻痹性肠梗阻。病例2和病例3接受了手术干预，但在手术时已明显处于濒危状态，在手术期间或术后24小时内死亡。对于出现食欲不振和粪便产量大幅下降的长颈鹿，应考虑胃肠道梗阻，需要积极的支持治疗和早期手术干预。腹部探查手术可能对诊断和治疗是必要的。基于少数病例，长颈鹿胃肠道梗阻的预后较差。
