The authors reflects on the use of self-expandable metallic stents (SEMS) for esophageal variceal hemorrhage. They state that traditionally SEMS were used for a variety of malignant and benign esophageal disorders. The authors further claim that while endoscopic band litigation is the treatment of choice for most patients, SEMS appear to be more effective, easier to insert and have lower risks of complications.

Acute gastrointestinal perforations occur either from spontaneous or iatrogenic causes. However, particular attention should be made in acute iatrogenic perforations as timely diagnosis and endoscopic closure prevent morbidity and mortality. With the increasing use of diagnostic endoscopy and advances in therapeutic endoscopy worldwide, the endoscopist must be able to recognize and manage perforations. Depending on the size and location of the defect, a variety of endoscopic clips, stents, and suturing devices are available. This review aims to prepare and guide the endoscopist to use the right tools and techniques for optimal patient outcomes. [ABSTRACT FROM AUTHOR]
