The objective of this study was to compare 2 surgical approaches (scrotal or abdominal) for castration of guinea pigs and to investigate post-operative infection rates with either technique. Forty-eight guinea pigs were castrated by scrotal or abdominal technique after being randomly assigned to 1 of 2 groups (n = 24). Individuals were either castrated by an experienced exotic animal surgeon (n = 12) or by an experienced small animal surgeon (n = 12). Surgical wounds were evaluated daily before euthanasia for histological evaluation 2 wks after surgery. Post-operative infection rate was significantly higher in the scrotal group than in the abdominal group, with a higher rate for the experienced small animal surgeon. Castration of guinea pigs with the abdominal technique is significantly faster and has a significantly lower post-operative infection rate than the scrotal technique.
本研究的目的是比较豚鼠去势的两种手术方法（阴囊或腹部），并调查两种技术的术后感染率。48只豚鼠被随机分为2组（每组n = 24），分别采用阴囊或腹部技术去势。个体要么由经验丰富的外来动物外科医生进行去势（n = 12），要么由经验丰富的小动物外科医生进行去势（n = 12）。在术后2周进行组织学评估前，每天对手术伤口进行评估，直至安乐死。阴囊组的术后感染率显著高于腹部组，经验丰富的小动物外科医生的感染率更高。与阴囊技术相比，采用腹部技术对豚鼠进行去势明显更快，术后感染率也显著更低。
