Massive Upper Gastrointestinal Bleeding from a Traction Type of Diverticulum in the Midesophagus / 대한소화기내시경학회지

ABSTRACT

The common sites of esophageal diverticula are the pharyngoesophageal junction, midesophagus and epiphrenic. The pathophysiological mechanisms of acquired esophageal diverticula are traction and pulsion forces. Traction diverticula of the midesophagus are usually asymptomatic, and found incidentally on an esophagogastroduodenoscopy or barium contrast esophagogram. Midesophageal traction diverticula are caused by inflammatory processes between the external wall of the esophagus and the adjacent structure. Pneumonia, bronchoesophageal fistula and gastrointestinal bleeding can occur due to an extension of inflammatory process into the lung or blood vessels. There are a few reports of midesophageal diverticular bleeding. We present a case of massive upper gastrointestinal bleeding from a traction diverticulum of the midesophagus that was successfully managed by endoscopic treatment.
