Bariatric surgery has been growing in France for more than ten years, as in other Western countries. Complications of bariatric surgery vary according to the surgical technique, the volume of activity of the center, the experience of the surgeon, and the patient's condition (comorbidities, superobesity). There are many different bariatric surgery techniques, but in practice, three procedures are commonly performed, essentially by laparoscopy: gastric banding, sleeve gastrectomy (restrictive techniques), and gastric bypass with Roux-en-Y gastric bypass (or RYGB, a mixed technique, restrictive and malabsorptive). The management of these procedures is complex and requires a multidisciplinary approach: Medical and surgical, radiological, and if necessary, intensive care. Complications are multiple (anastomotic ulcer, fistulas/anastomotic disunion, Luminal stenosis) and call for various endoscopic techniques, often discussed in first intention. Endoscopic management is still poorly codified, in the absence of recent international or national recommendations.
