A 4-year-old recently castrated male alpaca was referred for preputial prolapse of 4 d duration. Clinical findings upon admission were a 5 cm edematous preputial prolapse with the exposed preputial epithelium ulcerated and slightly necrotic. Initial therapy included NSAIDs and local treatment. A severe local inflammatory reaction with a consequent paraphimosis occurred on the penis and prepuce presumptively secondary to the use of a common compound ointment (, tetracycline, scarlet oil, and lanolin) 24 h after its application. Medical treatment and local debridement were unsuccessful in reducing the paraphimosis. The prolapse was successfully reduced by traction of the penis through a para-preputial incision under general anesthesia. The alpaca was discharged after 22 d in hospital. The alpaca is still in the herd 24 mo after discharge with no prolapse recurrence.
一只最近被去势的 4 岁雄性羊驼出现包皮脱垂，病程 4 天。入院时的临床检查发现，有 5 厘米水肿性包皮脱垂，暴露的包皮上皮溃疡且轻微坏死。最初的治疗包括使用非甾体抗炎药和局部治疗。在使用一种常见的复合软膏（含四环素、猩红油和羊毛脂） 24 小时后，阴茎和包皮发生严重的局部炎症反应，继而发生嵌顿。尽管使用了药物治疗和局部清创术，但仍无法减轻嵌顿。在全身麻醉下通过包皮旁切口牵引阴茎成功地使包皮脱垂复位。羊驼在医院住院 22 天后出院。出院后 24 个月，这只羊驼仍在羊群中，没有再次出现包皮脱垂。
