Disorders of sexual development (DSD) in dogs involve most commonly an XX sex reversal syndrome, treated conventionally by gonadohysterectomy. The objective of the present case series is to describe the surgical treatment and long‐term follow‐up of dogs undergoing laparoscopic gonadectomy without hysterectomy for treatment of ovotesticular DSD. Six female dogs clinically diagnosed with DSD were retrospectively included in the study when laparoscopic gonadectomy was performed and histology confirmed the presence of abnormal gonads. The dogs were evaluated by ultrasound after 6 months, and owners were contacted by phone for the long‐term reevaluation. Laparoscopic gonadectomy was performed using 2‐ or 3‐portal midline techniques with 3‐ and/or 5‐mm instruments. Additional procedures were performed in 5 dogs, including os clitoris removal in 4 dogs and vulvoplasty in 1 dog. Histological analysis of the gonads reported 11 ovotestes and 1 testis. No major or minor complications occurred perioperatively. Ultrasonographic reevaluation was performed in 5/6 dogs and the remaining abdominal genital system was considered normal. Median long‐term follow‐up was 617 days (range, 265–1597) with none of the dogs having any symptom related to DSD. Therefore, laparoscopic gonadectomy is a valid alternative for dogs with ovotesticular DSD and is less invasive than conventional open techniques. Removal of the gonads avoids future development of hormone‐related diseases of the remaining genital tract.

患有卵睾丸性发育障碍的狗的腹腔镜性腺切除术。

狗的性发育障碍（DSD）最常见的是XX性逆转综合征，通常通过性腺切除术治疗。本病例系列的目的是描述接受腹腔镜性腺切除术而无子宫切除术的狗的手术治疗和长期随访，以治疗卵睾DSD。当进行腹腔镜性腺切除术并且组织学证实存在异常性腺时，将六只临床诊断为DSD的雌性犬回顾性纳入研究。6个月后通过超声对狗进行评估，并通过电话与主人联系以进行长期重新评估。腹腔镜性腺切除术是使用2或3门中线技术和3或5毫米器械进行的。对5只狗进行了额外的手术，包括除去阴蒂骨4只，外阴成形术1只。性腺的组织学分析报告了11个卵睾丸和1个睾丸。围手术期无重大并发症。对5/6只狗进行了超声检查，其余腹部的生殖器系统被认为是正常的。长期随访的中位数为617天（范围265-1597），所有狗均无与DSD相关的症状。因此，腹腔镜性腺切除术对于患有卵睾DSD的狗是一种有效的替代方法，并且比常规开放技术的侵入性小。去除性腺可避免未来生殖器官激素相关疾病的发展。
