I've either read or seen on TV maybe ?? It is being done using laparoscopic (not sure of spelling) surgery--small incisions and mini camera--much less invasive. Since it's fairly new though there's likely a limited amount of animal hospitals that can perform the laparoscopy.
Just wanted to say Welcome to the boards and thanks for your feedback. Its actually a surgery that's been around for awhile but your right, it can be done laparoscopically. There is still a long recovery afterwards.
