Gastrointestinal webs are an uncommon cause of congenital or acquired stenoses, and have been identified in a number of locations in the gastrointestinal tract. The most common webs occur in the esophagus, gastric antrum, and duodenum. An outline of the clinical presentation, diagnosis, and management of webs in these locations is presented. The pathogenesis of webs is poorly understood and the approach to their management remains in evolution.
