American Society for Metabolic and Bariatric Surgery (ASMBS) is the largest society for this specialty in the world. Foremost American surgeons have formed the society's leadership and have established an excellent organization with educational and support programs for surgeons and allied health professionals.
At present the ASMBS "Resources" and "Guidelines and Statements" offer links to numerous well researched and informative publications. A useful document for all dietitians practising in bariatric surgery includes "Bariatric Surgery: Postoperative Concerns". The paper provides guidelines on several aspects of nutritional management following all types of bariatric surgery.
Please Note: ASMBS is due to release comprehensive evidence-based bariatric surgery best practice guidelines in June 2008. These guidelines will encompass all aspects of obesity surgery and all current bariatric procedures. The guidelines will include numerous recommendations for pre- and post-operative nutritional requirements and care. These directives will be based on a thorough scientific review of available nutritional research/literature.
The ASMBS bariatric surgery best practice guidelines will be accessible to the public under the "Guidelines and Statements" link from ASMBS website.
