A 7-year-old castrated male llama was admitted for evaluation of mild colic. Exploratory celiotomy revealed a diaphragmatic hernia that was entrapping the proximal portion of the ascending colon. The hernia was reduced, and the devitalized ileum, cecum, and 45 cm of the proximal portion of the ascending colon were resected. Surgical repair of the defect in the diaphragm could not be accomplished from the ventral celiotomy, and the owners declined definitive repair via left thoracotomy. The llama recovered and did well until 9 months after surgery, when the hernia recurred. Necropsy revealed a defect, with characteristics consistent with a congenital origin, in the dorsal part of the left hemidiaphragm. On the basis of the findings in this llama, repair of such defects is strongly advocated.
一只7岁去势雄性美洲驼因轻度腹痛入院评估。剖腹探查发现膈疝，疝入物压迫升结肠近端。疝内容物还纳后，切除了坏死的回肠、盲肠及45厘米的升结肠近端。经腹手术无法修复膈肌缺损，主人拒绝经左胸进行确定性修复。这只美洲驼术后恢复良好，但术后9个月疝复发。尸检发现左半膈肌背侧有一缺损，其特征符合先天性病因。基于这只美洲驼的检查结果，强烈主张修复此类缺损。
