Performance standards in bariatric surgery

A bariatric surgeon is a fully trained general or gastrointestinal surgeon who has demonstrated specialized knowledge in the management of patients who suffer from morbid obesity and its complications. In addition to appropriate formal surgical training, preceptorships with experienced surgeons, preferably members of international bariatric societies, are highly desirable. Active participation in meetings of these societies, continuing medical education and knowledge of the current literature are necessary to maintain the required skills to treat these complex patients. Bariatric surgery should be performed at institutions that provide the necessary equipment, facilities and support systems for this particular population. When analysing outcomes of obesity surgery, long-term weight loss reports should include the number of patients followed and the time period of follow-up. Complications and re-operations should be presented, as well as modifications of techniques when various operations are compared. Weight loss should not be the only criterion used to define success or failure. Objective assessment of improvement in medical conditions related to obesity, and reliable measurements of quality of life after surgery should also be included in the final outcome analysis.
