Introduction: AGB (adjastable gastric bandin) is the most common method for treatment of obesity which is performed all around the world and provides a significant weight loss for patients. Despite all its benefits as a method that requires the least intervention, complications such as gastric prolapse, stoma stenosis and migration band may also occur. These complications rarely result in mortality, but usually the only treatment for them is surgery.

Case Presentation: We report a rare complication of this procedure which had caused small intestine obstruction.

Conclusions: Small intestine obstruction caused by band migration is a very rare complication and must be considered as a differential diagnosis in patients with small intestine obstruction symptoms. Therefore correct surgical methods must be adopted for its treatment so that it may not let the surgeon get misled during the operation and let him do the treatment correctly.
