[Body contouring surgery after massive weight loss. Part I: abdomen and extremities].

Body contouring surgery is traditionally part of plastic surgery training. Reconstructive techniques are needed most in trauma cases, tumor reconstructions, treatment of degenerative diseases and metabolic diseases such as Madelung's deformity, body contouring after massive weight loss, and all aesthetic plastic surgery. With various surgical techniques, liposuction became an important option in the overall treatment plan. Body contouring surgery in the massive weight loss patient is a rapidly expanding field of plastic surgery. Its challenge is the management of excess skin remaining after bariatric surgery. To achieve an aesthetic body contour, patients must accept numerous long scars. They must understand that recurrent laxity and scar migration is not necessarily a failure of the operation but rather an expected outcome. Body contouring surgery is challenging, time-consuming, and not without complications. The patient population has very real aesthetic and appearance concerns that must be addressed in an effective, definite, and safe manner.
