title: Endoscopic Management of Gastrointestinal Leaks and Fistulae.
abstract: Gastrointestinal leaks and fistulae can be serious acute complications or chronic morbid conditions resulting from inflammatory, malignant, or postsurgical states. Endoscopic closure of gastrointestinal leaks and fistulae represents major progress in the treatment of patients with these complex presentations. The main goal of endoscopic therapy is the interruption of the flow of luminal contents across a gastrointestinal defect. In consideration of the proper endoscopic approach to luminal closure, several basic principles must be considered. Undrained cavities and fluid collections must often first be drained percutaneously, and the percutaneous drain provides an important measure of safety for subsequent endoscopic luminal manipulations. The size and exact location of the leak/fistula, as well as the viability of the surrounding tissue, must be defined. Almost all complex leaks and fistulae must be approached in a multidisciplinary manner, collaborating with colleagues in nutrition, radiology, and surgery. Currently, gastrointestinal leaks and fistulae may be managed endoscopically by using 1 or more of the following modalities: stent placement, clip closure (including through-the-scope clips and over-the-scope devices), endoscopic suturing, and the injection of tissue sealants. In this article, we discuss these modalities and review the published outcomes data regarding each approach as well as practical considerations for successful closure of luminal defects.
