Gastric Diverticulum: A Comprehensive Review

Gastric diverticula (GD) are outpouchings of the stomach wall that typically form in the fundus. They are the least common gastrointestinal diverticula, and are very rare anatomic abnormalities overall.

Although most GD are asymptomatic and are usually discovered incidentally during routine diagnostic testing, they can present with variable symptoms. Occasionally, complications can develop that may be life-threatening and are indications for surgical management.

Here, we provide a literature review of GD where we discuss the pathogenesis, clinical manifestations, investigations and diagnostic approach, and various management options for this uncommon disorder.
