A new, less invasive, laparoscopic-laparotomic technique for the cryptorchidectomy in the dog.

A new, less invasive technique of cryptorchidectomy in the dog is described. The technique makes use of a laparoscope equipped with a telescope for diagnostic purposes (identification of testicle site); and then of a forceps to grasp the deferent duct and force the testicle through a small, laparotomic incision, 2.5 cm long, in the parapenien site. Variations, according to the kind of cryptorchidism (bilateral or unilateral, abdominal, inguinal), are also discussed. The operation ends with suturing of the vascular stem of the testicle (resorbable sutures) and orchiectomy. This technique is easy to carry out and has the advantage of not being invasive since it does not involve a median laparotomy preceded by overturning of the penis. Three operations have been performed: two on cases of unilateral cryptorchidism and one on a case of bilateral cryptorchidism.
