Closed-perforation of gastric fundus and gastric outlet obstruction caused by a giant gastric trichobezoar: A case report.

A bezoar is a mass formed because of the accumulation of indigestible material in the stomach and/or small intestine. Bezoars are rare but occasionally occur with acute abdomen findings. Bezoars form as a result of changes in the gastrointestinal system anatomy and physiology and repetitive exposure to the ingested material. These materials can include vegetables with high fiber content (phytobezoars), non-animal origin fats, hair (trichobezoars), or drugs such as anti-acids (pharmobezoars). Gastric bezoars frequently occur after gastric surgery. Psychiatric disorders such as trichotillomania (an irresistible urge to remove and swallow one's own hair) are frequently the underlying reason in patients without a history of gastric surgery. In this article, we presented a giant gastric trichobezoar obstructing outlet and causing closed-perforation and abscess formation of gastric fundus in a 30-year-old woman.
