Liposuction--removal of giant lipomas for weight loss in a dog with severe hip osteoarthritis.

An extremely obese, mixed breed dog, with severe bilateral hip osteoarthritis was presented with progressive hindlimb lameness. In addition, three giant lipomas were diagnosed, one causing mechanical irritation within the left axillary region. Previous treatments of dietary weight loss and non-steroidal anti-inflammatory drugs had failed. Minimally invasive liposuction of the lipomas was performed, resulting in weight loss of 3 kg, representing 10 per cent of the dog's bodyweight. Conservative treatment was continued, and the dog improved rapidly postoperatively. Liposuction of lipomas may be considered as an alternative to traditional surgical resection in cases where seroma formation and delayed wound healing may be expected. Acute weight loss through liposuction may improve lameness associated with osteoarthritis and motivate the owner compliance for further weight loss.
