To describe cryptorchidectomy performed with a paramedian or inguinal approach in domestic pigs and compare findings for commercial-breed pigs with those for pot-bellied pigs.
47 client-owned (33 commercial-breed and 14 pot-bellied) pigs.
Medical records were searched to identify pigs that underwent surgical treatment for cryptorchidism from 2000 to 2018. Signalment, location of retained testes, surgeon, surgical approach, surgery time, anesthesia time, and postoperative complications were recorded. Complications were assessed with long-term follow-up. Age and surgical variables were compared between commercial-breed pigs and pot-bellied pigs.
Retained testes were most commonly located in the abdomen (27/47 [57%] left-sided, 15/47 [32%] right-sided, and 2/47 [4%] bilateral); 2 pigs each had 1 retained testis in the inguinal region, and 1 pig had 1 retained testis in the abdomen and 1 in the inguinal region. Forty-four pigs with abdominally retained testes were treated successfully with a paramedian surgical approach, including 3 for which an inguinal approach was attempted first. An inguinal approach was successful for 3 pigs with inguinally retained testes and 1 with an abdominally retained testis. Standard castration techniques were used for normally descended and inguinally retained testes. Long-term follow-up was available for 34 pigs; minor complications were reported for 3 (9%). Pot-bellied pigs were significantly older than commercial-breed pigs. No other intergroup differences were found.
The paramedian surgical approach was successfully used for removal of abdominally retained testes in all pigs that underwent the procedure. The overall complication rate for cryptorchidectomy in the study sample was low.
描述经腹侧或腹股沟途径进行的隐睾切除术，并比较商品猪和大肚猪的发现结果。
47 头客户所有的（33 头商品猪和 14 头大肚猪）猪。
检索了 2000 年至 2018 年接受手术治疗隐睾症的猪的医疗记录。记录了一般情况、保留睾丸的位置、外科医生、手术途径、手术时间、麻醉时间和术后并发症。通过长期随访评估并发症。比较了商品猪和大肚猪的年龄和手术变量。
保留的睾丸最常位于腹部（27/47 [57%] 左侧，15/47 [32%] 右侧，2/47 [4%] 双侧）；2 头猪每侧各有 1 个保留睾丸位于腹股沟区，1 头猪有 1 个保留睾丸位于腹部和 1 个位于腹股沟区。44 头腹部保留睾丸的猪成功地接受了腹侧手术途径治疗，其中 3 头首先尝试了腹股沟途径。腹股沟途径成功治疗了 3 头腹股沟保留睾丸的猪和 1 头腹部保留睾丸的猪。正常下降和腹股沟保留睾丸采用标准的去势技术。34 头猪有长期随访资料；报告有 3 例（9%）出现轻微并发症。大肚猪比商品猪明显年龄大。未发现其他组间差异。
所有接受该手术的猪均成功地使用腹侧手术途径切除了腹部保留的睾丸。研究样本中隐睾切除术的总体并发症发生率较低。
