Abstract
Background: Anastomotic leaks are a major source of morbidity and mortality after esophagectomy, with an incidence of 4-17%, and associated mortality of up to 45%. Conservative therapy of prolonged leaks (>2 weeks) has a success rate of 60%, requiring an average of 13 weeks for closure (Bueno JT et al, GIE 2003). Prior studies on the use of a silicone-covered self-expanding polyester stent (Polyflex, Boston Scientific, Natick, MA) for leak closure illustrated a 90-100% success rate, with a low rate of stent migration.
