Liposuction. Image 8 of 15. Cannula inserted into fat tissue around the hips of a middle-aged man during liposuction surgery. The surgeon's gloved hand is also seen. The cannula is attached to a vacuum pump, which sucks the fat tissue out of the body. Liposuction removes excess fat and sculpts the body. As with all surgery there is a risk of infection, excess bleeding and other complications. For a sequence showing liposuction surgery see M590/339 to M590/353.
