Article Abstract
Objective: To document laparoscopic cryptorchidectomy with a vessel-sealing device in dorsal recumbent horses.
Study Design: Retrospective study.
Animals: Forty-three male horses.
Methods: Food was withheld for 36 hours before horses were placed under general anesthesia and positioned in dorsal recumbency. One laparoscopic portal and 2 instrument portals were placed for the laparoscopic procedure. A third instrument portal was created in bilateral cryptorchid horses. A vessel-sealing device was used for hemostasis and transection of retained testes. Descended testes were removed via closed castration with primary closure of the scrotal incision. Time required for removal of the retained testis and perioperative complications were recorded. Short-term (14, 30, 60 days) and long-term follow-up (>1.5 years) consisted of telephone interview with owners and referring veterinarians.
Results: Forty-three male horses underwent laparoscopic cryptorchidectomy. Thirteen horses were bilateral cryptorchids, 19 were unilateral cryptorchids with a descended testis, and 11 were unilateral cryptorchids with 1 testis previously removed. Inguinal testes, identified in 5 horses, were pulled into the abdomen prior to excision. The vaginal ring was apposed with endoscopic staples in 3 of 5 horses. Mean surgery time was 31.34 ± 7.41 minutes. No intraoperative or immediate postoperative complications were encountered. No short-term or long-term complications were reported.
Conclusion: Laparoscopic cryptorchidectomy can be safely performed with a vessel sealing-device in dorsal recumbent horses. This method was effective and did not result in any complication in our case series.
This study evaluates a new multiport device with single access to the abdominal cavity produced with routine hospital supplies that could be applied to laparoscopically assisted cryptorchidectomy in standing horses. Initially, the new device was evaluated on five cadavers of bovine fetuses ( = 5), placed assisted in a minilaparotomy performed in the flank region. Subsequently, the device was evaluated in four cryptorchid horses treated during the hospital routine.
Objective: To describe a modified laparoscopic-assisted cryptorchidectomy technique in dogs using a single-port endoscope and evaluate clinical outcome in abdominal cryptorchid dogs that underwent the procedure.
Study Design: Prospective case series.
Animals: A total of 14 client-owned dogs (19 abdominal cryptorchid testes).
Cryptorchidism is heritable in cats, and due to the pathological risk of testicular torsion, and the development of testicular neoplasia, cryptorchidectomy is the treatment of choice. For the intra-abdominal testes, a laparotomic approach is generally recommended; however, laparoscopic cryptorchidectomy in cats has been documented in a few clinical case reports. The aim of the study was to report the short-term clinical outcomes for 19 cryptorchid cats with intra-abdominal testes that underwent cryptorchidectomy with laparoscopic techniques.
Cryptorchidism is defined as the failure of the testis to descend into the scrotal position. Bulls with cryptorchidism have problems in both meat quality and husbandry management; thus, it is greatly important to accurately identify the retained testis and remove it during the early stage. Abdominal computed tomography (CT) was performed under general anesthesia in 34 bulls aged 3-9 months with cryptorchidism.
