The paper describes the occurrence of a rare complication - portal and systemic venous air embolism - after endoscopic retrograde cholangiopancreatography, related to the endoscopic procedure.

Endoscopic management of recurrent tracheoesophageal fistula induced by chronic use of nonsteroidal anti-inflammatory drugs: A case report and review of the literature.

Tracheoesophageal fistula (TEF) is frequently congenital and requires surgical correction. TEF can also occur secondary to malignant esophageal tumors or benign diseases and these cases are managed by endoscopic means, such as closing the defect with metallic stents. Although esophageal injury can occur secondary to nonsteroidal anti-inflammatory drugs (NSAIDs), TEF secondary to chronic NSAIDs use has not been described in the literature.

An atypical type I gastric neuroendocrine tumor.

Type I are multiple small polypoid lesions with central ulceration located in the gastric body or the fundus, associated with atrophic gastritis usually noninvasive and very rarely metastatic.
