The aim of this poster is to review surgical anatomy and normal post-operative images after metabolic surgery, including roux-en-y gastric bypass, adjustable gastric banding and sleeve gastrectomy, providing an illustrated guide comparing to normal anatomy. In addition, we review the main complications associated with each of these procedures, using different imaging methods and highlight the major clinical signs associated with these complications, relevant to the radiologist.

Obesity is a major health problem worldwide and has enormous financial implications associated. There are a significant number of "metabolic" diseases and conditions, associated with obesity, like hypertension, diabetes, dyslipidemia, coronary artery disease, osteoarthritis, obstructive sleep apnea, among others, and with social problems, accompanied by increased mobility and mortality, which is proportional to the degree of excess weight. Nonsurgical management of obesity includes drug therapy, dietary changes, and exercise, which can facilitate weight loss. However, this is often not enough in patients with severe obesity,...

Radiology plays a crucial role in postoperative assessment after metabolic /bariatric surgery, and therefore, radiologists should be familiar with the surgical technique which can significantly change the normal anatomy of the upper gastrointestinal tract and be aware of standard findings after these procedures. Besides, there are several complications associated with each type of method, requiring high suspicion according to the clinical presentation. Recognizing them in the several available imaging studies is essential. Bypass Procedures 1) Roux-en-Y Gastric Bypass Roux-en-Y Gastric Bypass (RYGB) is the bariatric...

It is crucial that radiologists understand the normal postoperative anatomy and recognize complications, seeing that some of them are surgical emergencies that require timely intervention.
