Enteral stents in the management of post-bariatric surgery leaks.

A post-bariatric surgery leak is a rare but grave condition and remains every bariatric surgeon's nightmare. Endoscopic therapy with the insertion of self-expandable stents provides an effective minimally invasive approach for the management of leaks. Self-expandable stents, however, are still hampered by their tendency for migration and are not always well tolerated. Recently, double-pigtail stents have been proposed as an alternative endoscopic therapeutic modality. Both types of stents have been shown to be very effective in the management of leaks; however, most studies have pooled gastrointestinal leaks due to different etiologies together. In this article, we review the current status and foreseen innovations in gastrointestinal stenting for post-bariatric surgery leaks.
