Abstract:
Obesity is one of the most significant health problems worldwide. Bariatric surgery has become one of the fastest growing operative procedures and has gained acceptance as the leading option for weight-loss. Despite improvement in the performance of bariatric surgical procedures, complications are not uncommon. There are a number of unique complications that arise in this patient population and require specific knowledge for proper management. Furthermore, conditions unrelated to the altered anatomy typically require a different management strategy. As such, a basic understanding of surgical anatomy, potential complications, and endoscopic tools and techniques for optimal management is essential for the practicing gastroenterologist. Gastroenterologists should be familiar with these procedures and complication management strategies. This review will cover these topics and focus on major complications that gastroenterologists will be most likely to see in their practice.
