Gastric bezoar complicating laparoscopic adjustable gastric banding, and review of literature.

Gastric bezoars may be formed in the normal stomach as a result of foreign body consecrations of various objects with inability to pass through the pylorus. Classically, most bezoars occur as a complication of gastric surgery which creates a low acid environment, decreased peristalsis, and abnormal pyloric function. Bariatric surgery has been associated with a low incidence of bezoar formation. However, to date there has been no documentation of bezoars occurring after laparoscopic adjustable gastric banding, which is one of the surgical options available for the treatment of morbid obesity. We report a case of a gastric bezoar that occurred 8 months after gastric banding.
