Abstract
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, includingos clitorisremoval 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.
