Abstract
Background To analyze the outcomes of a series of endoscopically placed polyester self-expanding polyflex stents (SEPSs) for the management of anastomotic leaks after Roux-en- Y bypass. Anastomotic leaks after gastric bypass cause significant morbidity and mortality. Covered polyester SEPSs might have a role in the treatment of these leaks. Methods A retrospective chart review was performed from January 2006 to November 2006 that included all acute and chronic leaks treated with SEPSs. Results A total of 6 patients were treated with stents, with a mean procedure time of 22 minutes. Of these 6 patients, 5 had acute postoperative leaks and 1 had a chronic fistula. Five patients started oral intake 1–6 days after their procedure. All acute leaks had complete healing at a median of 44 days. The patient with a chronic gastrocutaneous fistula required revisional surgery for fistula closure. In addition, 5 patients had stent migration, and 3 required stent replacement. Conclusion An endoscopically placed SEPS provides a less-invasive alternative to treat acute anastomotic leaks after Roux-en- Y bypass while simultaneously allowing oral intake. The results of this case series have demonstrated this treatment to be safe and effective.
