Gastrointestinal surgery includes small intestine bypass, gastroplasty and gastric bypass. Among them, small bowel bypass surgery was eliminated because of its extremely serious complications and unpredictable and even irreversible consequences. At present, gastroplasty and gastric bypass are popular. The two operations have their own advantages and disadvantages: although gastroplasty is relatively less weight loss and easy to regain weight, it is simple to operate and has few complications, so it is popular abroad at present; Although gastric bypass operation is complicated and complications, especially malnutrition, occur frequently, weight loss continues to be effective. If you pay attention to supplement and adjust the nutritional status after operation, you can get safe and effective results.
Excessive fat in obese patients mainly accumulates in abdomen, iliopsoas, buttocks, inner and outer thighs, breasts, inner upper arms, calves, mandibular neck and other parts. The accumulation of fat in these parts will cause local uplift and affect the beauty of the body. In severe cases, due to excessive fat accumulation, it will form a drooping shape, such as abdominal apron deformity, which will not only affect the beauty of the body, but also cause inconvenience in movement and life. Local liposuction treatment of local fat accumulation includes local fat accumulation liposuction and local skin fat relaxation liposuction. The former includes wet liposuction, tumescent liposuction and ultrasonic liposuction. Compared with wet liposuction, that is, traditional liposuction, tumescent liposuction and ultrasonic liposuction have less injuries and fewer complications, so they are increasingly favored by doctors and patients. Tumescent liposuction was introduced by Klein in 1987, that is, on the basis of wet method, a large number of local anesthetics with low concentration were injected locally, and the mixed solution of 1: 1000 adrenaline, sodium bicarbonate and normal saline was used for aspiration, which has the advantages of less blood loss, safety, rapid aspiration of a large amount of fat and long anesthesia time.
Ultrasonic liposuction was initiated by Zocchi on 1992. This technique is a combination of ultrasonic wave and swelling method, which uses ultrasonic wave to act on loose swollen fat to emulsify it and then absorb the emulsion. The advantages of this method are less bleeding and fewer complications, but the liposuction efficiency is low and the operation time is long.
