Success of a bariatric surgery will always depend on a series of factors. To be an effective and safe procedure requires a great dedication and a complete understanding of how to manage obese patients. The clinical and surgical team should consider morbid obesity as a disease and not a concern regarding moral failing. When a medical team decides to be involved with a bariatric surgery program, all must be prepared to care for critically ill bariatric surgical patients with regards to cardiopulmonary failure, serious wound problems, and ventilatory and nutritional support. Besides doctors it is necessary to have a complex team prepared to give support, such as nurses, social workers, dieticians, and physical therapists. The infrastructure of the hospital must have beds, wheelchairs, stretchers, chairs, and image and surgical equipment capable of managing very obese patients.
