Abstract

Abstract : Background: Endoscopic stenting is widely used to manage benign and malignant strictures, postoperative stenoses, or anastomotic leaks and fistulas. Materials and Methods: However, Over the Wire delivery systems are generally short and quite stiff, and therefore, cannot reach distal parts of the gastrointestinal tract or cross severely angulated strictures. In such cases, we used the Over-the-Scope stenting (OTSS) technique to deliver and deploy endoscopically large-bore fully covered stents. We present herein a series of 11 patients treated with the OTSS technique for a variety of indications. To our knowledge, this is the largest series of OTSS cases published. Results: The stents were correctly deployed in 10 cases. In one case, the stent was dislocated during scope withdrawal and Through the Scope stenting was performed with a smaller diameter uncovered stent instead. Predilation of the stricture was necessary in 5 patients. Clinical success was achieved in all patients. Conclusions: Our results encourage the use of the OTSS technique in cases where standard Over the Wire delivery systems of large-bore stents cannot reach or cross distal or tortuous strictures. The technique can also be used to reinsert migrated stents or misplaced braided-suture release mechanism (Ultraflex) stents.
