Abstract
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy. WHO classification of overweight according to BMI (kg/m2): Normal is 18.5–24.9, Overweight 25.0–29.9, Obese class I 30.0–34.9, Obese class II 35.0–39.9 and Obese class III is > 40.
Severe obesity is associated with multiple co morbidities which reduce the life expectancy and markedly impair the quality of life. Obesity-related problems begin at the head and end at the toes, affecting almost every organ in between. Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children. It is one of the most serious public health problems of the 21st century.
Obesity has reached epidemic proportions worldwide. Recent World Health Organization (WHO) projections estimate that globally in 2005 approximately 1.6 billion adults older than 15 years were overweight and at least 400 million adults were obese.
Currently, treatment for obesity consists of both medical and surgical interventions. Medical treatment consists of diets, exercise, behavioral modification and pharmacotherapy, alone or in combination. While these modalities can be effective in the short term, compliance is poor and hence long-term results are unsatisfactory. Surgical therapy achieves greater weight loss, that is also better sustained, compared with medical therapy, but has a higher morbidity and mortality.
Bariatric surgical procedures are an option for treating morbid obesity, by reducing intake or absorption of calories. There are various procedures, all of which have potential complications. Bariatric surgery should always be performed in a specialist centre, and long term follow-up of patients is necessary taking in consideration that bariatric surgical procedures are only indicated for people with severe obesity and not for individuals with a mild weight problem.
Bariatric surgery has changed dramatically in the last decade due to the increase in the prevalence of morbid obesity, the advent of new procedures, and growing demand for surgery.
Abdominal lipectomy is a common procedure among patients with massive weight loss especially following bariatric surgery. With the recent epidemic of obesity and the wide diffusion of bariatric surgery, this procedure has become even more frequent. Patient’s satisfaction is generally high because of the good cosmetic results that can be obtained in experienced hands. Routinely contour-improving techniques are combined to achieve a more harmonious result.
