Abstract Objective: to determine differences in the length of time of surgery, pain, and complications between laparoscopic cryptorchidectomy (CL) and cryptorchidectomy through mid-ventral laparotomy (CLMV) in dogs suffering from unilateral abdominal cryptorchidism. Materials and methods: 11 patients were used. The average weight of the dogs was 20 ± 9.6 kg, and the average age was 21 ± 12.8 months. Six and five dogs were assigned to CL and CLMV, respectively. Total surgery time and extraction time of abdominal and scrotal testis were measured. Pain evaluation was performed at 0, 1, 2, 4, 6, 12, and 24 hours after surgery using the pain scale developed by the University of Melbourne (UMPS). Complications were monitored during 24 hours by clinical assessment and ultrasonography. Results: cryptorchidism was more common in pure breeds and it affected mainly the right testicle. The operating time to remove the abdominal testis was significantly less using CLMV. Qualitative assessment of pain showed that all patients had mild pain, except for a patient in the CLMV group that showed higher pain. A statistically significant difference was found favoring the CL group in the assessment of pain at 2 h after surgery. A complication was detected in one patient of group CL four hours after surgery and was re-intervened. Conclusions: both procedures resulted in mild pain, with statistically significant differences only at 2 hours. CLMV took less time for removal of the testis. Post-surgery bleeding is a complication to consider when performing CL.
