[Esophageal diverticula (excluding cricopharyngeal diverticula)].

Diverticula of the middle and lower third of the esophagus are commonly associated with esophageal motility disorders. The increase of intraluminal pressure leads to an outpouching of the mucosal and submucosal layers through the esophageal muscle coat. These pouches are also called false diverticula, because they only consist of the mucosal and submucosal esophageal layers. In contrast, the more rarely encountered true diverticula that retain the complete esophageal wall are generally associated with periesophageal granulomatous lymph node disease. Treatment of both true and false diverticula is generally indicated in symptomatic patients; however, even state of the art minimally invasive surgery is accompanied by considerable perioperative morbidity and should only be performed in carefully selected patients. This aim of this article is to summarize the available scientific evidence and to provide the reader with an updated guide to best clinical practice in the treatment of esophageal diverticula.
