Bariatric surgery is one of the fastest growing hospital procedures performed in the United States. It is estimated that 220,000 weight-loss surgeries were performed in 2008 .
Complications following surgical treatment of severe obesity vary based upon the procedure performed and can be as high as 40 percent [2,3]. Due to the high surgical volume, improving the safety of these operations has become a high priority, leading to the development of strict criteria for center accreditation, guidelines for safe and effective bariatric surgery, and careful monitoring of surgical outcomes [4-8].
This topic will review the major late complications of bariatric surgery. A description of bariatric procedures, indications and preoperative management, short-time medical outcomes, and long-term complications of laparoscopic operations are reviewed as separate topics.
