To compare a prescrotal castration technique with the conventional bilateral scrotal incision technique for castration of llamas.
Prospective randomized controlled trial.
10 clinically normal, sexually intact male llamas.
Five llamas were castrated by use of a 5-cm skin incision located 2 to 3 cm lateral to the ventral midline and approximately 15 cm cranial to the scrotum, which was closed with absorbable suture material to allow primary healing. Five other llamas were castrated via a more conventional technique, with a 5-cm scrotal incision positioned directly over each testis, which was allowed to heal by second intention.
The prescrotal technique required significantly more time to complete; however, no additional anesthesia was required to complete the longer procedure. Llamas castrated with the prescrotal technique required less aftercare and had less incisional pain when the area was palpated.
Both techniques are safe and effective. Some clients, however, find the prescrotal technique more aesthetically acceptable. The prescrotal technique may be more clinically important where fly control is difficult.
比较阴囊前去势技术与传统双侧阴囊切开技术对美洲驼去势的效果。
前瞻性随机对照试验。
10只临床健康、性成熟的雄性美洲驼。
5只美洲驼通过在腹侧中线外侧2至3厘米、阴囊上方约15厘米处做一个5厘米的皮肤切口进行去势，切口用可吸收缝合材料缝合以实现一期愈合。另外5只美洲驼采用更传统的技术，在每个睾丸正上方做一个5厘米的阴囊切口，任其通过二期愈合。
阴囊前技术完成手术所需时间显著更长；然而，完成较长手术过程无需额外麻醉。采用阴囊前技术去势的美洲驼术后护理需求较少，触诊切口部位时疼痛较轻。
两种技术均安全有效。然而，一些客户认为阴囊前技术在美学上更易接受。在蝇类控制困难的情况下，阴囊前技术可能在临床上更具重要性。
