Revisional Bariatric Surgery in a Single-Center Experience: Indications and Techniques

Bariatric surgery is currently considered the most effective treatment of morbid obesity and its comorbidities, including arterial hypertension, diabetes, OSAS and dyslipidemia. However, in a variable percentage of cases, therapeutic success is not achieved with primary bariatric surgery. Therefore, in the event of weight regain, inadequate weight loss, failure to control comorbidities or long-term complications, it is possible to resort to revisional surgery, aimed at relieving weight regain or complications. Revisional bariatric surgery is technically more complex than primary bariatric surgery because it is carried out in an operative field that is hampered by scarring from the first operation and on a modified anatomy. This chapter aims to describe the most common scenarios that may set the indications for revisional bariatric surgery, the surgical techniques employed in the authors experience and the postoperative follow-up.
