Minimally invasive ovariectomy or ovariohysterectomy can be performed safely and rapidly and is now considered a routine laparoscopic procedure. During this procedure a small camera port is established one centimeter below the umbilicus. Using the Hasson technique a trocar- cannula is inserted into the tiny incision in the body wall which allows abdominal insufflation to proceed.
Using a mechanical insufflator that has a pressure feedback mechanism we can insufflate the abdomen with carbon dioxide without exceeding the maximal recommended intra-abdominal pressure of 15 mmHg. Once a pneumoperitoneum is established we can place two further ports that allow instruments into the abdomen with which we can manipulate the ovaries and the body of the uterus.
Using special vessel-sealing technologies used routinely in human laparoscopic surgery we are able to safely seal the blood vessels that supply the ovaries and uterine body even in very large dogs. Once the blood supply to the ovaries and uterus has been removed it is possible to exteriorize the organs from the body which is done by slightly increasing the size of one of the port incisions. At the end of the procedure the dog is left with three tiny 1cm incisions.
