This is a video of a retained testicle from a laparoscopic removal. It shows the testicle hiding inside the abdomen, and not on the outside of the dog, as nature and anatomy intended. Retained testicles in the abdomen are a very serious cancer risk. They will often turn malignant as the animal ages.
But the traditional surgery to remove these retained parts is invasive and painful. It often requires a large incision on the side of the abdomen. It is more painful than most standard abdominal procedures, and the recovery is often longer than exploratory surgery.
But not with minimally invasive laparoscopic surgery. The incision is only was big as the testicle we remove. So there is a much smaller incision, way less bleeding, and a much faster recovery. To my knowledge, we are the only veterinary hospital performing these procedures in southeastern Massachusetts, if not further.
