Endoscopic extraction of a loose Fobi ring in a patient with gastric bypass.

Obesity has become a worldwide problem with a growing incidence, posing a risk to health, especially for cardiovascular disease, diabetes, certain types of cancer, depres-sive syndrome, and others. The methods of obesity treatment are still expanding, in addition to diet and exercise measures, pharmacological, endoscopic and surgical treatment is possible. One of the commonly performed bariatric surgical procedures is the Roux-en-Y gastric bypass, which combines restrictive and malabsorptive effects. As part of the development of new methods, the banded gastric bypass using the Fobi ring has been introduced. Its advantage is greater efficiency in reducing and maintaining -weight. One of the described complications is the migration of the Fobi ring, which can be addressed endoscopically today.
