• Outcomes following anaesthesia and surgery in the morbidly obese are reasonably good. • Several large reported series have failed to confirm body mass index as an independent risk factor for adverse outcome. • Poor outcome is related to the presence of co-morbidities. • Patients undergoing open surgery have been shown to develop higher post-operative into abdominal pressures than those undergoing similar surgical procedures laparoscopically. • Three principles underlying bariatric surgery are reduction in stomach size, gastric outlet restriction, and malabsorption. • Early surgical procedures such as jejunoileal bypass had an unacceptably high post-operative complication rate. • Current surgical procedures include laparoscopic adjustable gastric banding and gastric bypass Roux loop reconstruction. • These techniques have a relatively low complication rate. • There is a clearly demonstrable effect of programs size, with larger programs having better outcomes.
