Liposuction takes fat from the body. For liposuction of the abdomen, the technician inserts small, thin tubes called cannula through small cuts in the abdominal area, sucking out fat while the doctor relocates the tubes to attack specific deposits of fat, explains WebMD.
Advancements in technology have produced three techniques that make the process of liposuction easier, safer and more comfortable, states WebMD. Ultrasound-assisted liposuction turns the fat into liquid, making the fat simpler to remove. This technique is especially helpful in pulling fat out of the back, sides and upper abdomen. Tumescent liposuction involves the use of a local anesthetic at the point of needle insertion. The doctor injects an anesthetic into the fatty tissue before moving on to traditional liposuction.
The last type of liposuction is laser-assisted, according to WebMD. The laser turns the fat to liquid, and then the doctor pulls it out through a cannula. Most liposuction surgeries are performed as an outpatient procedure and do not necessitate an overnight stay unless an unusually large amount of fat is going to come out. Doctors often use local anesthesia and a sedative, unless a particularly large area is under liposuction, in which case a general aesthetic may be used.
