    Abstract:
    Esophageal strictures are a common problem causing significant morbidity for affected patients. Most can be treated safely and successfully with esophageal dilation. We have treated two patients with post-radiation esophageal strictures so tight that standard dilation technique failed even with an aggressive approach. We utilized a technique for operative dilation of these strictures using both antegrade and retrograde endoscopes. This approach for refractory esophageal strictures has only twice been previously reported. In both patients, a gastrostomy was placed and an endoscope was subsequently passed from the stomach retrograde up to the level of the stricture. Another endoscope was passed from above down to the proximal portion of the stricture. Illuminating the stricture, using fluoroscopy, carefully passing a wire, and grasping and pulling the wire with forceps from the opposite endoscope allowed for safe passage through the stricture. Savary dilators were utilized to effectively dilate the strictures. A method for protection of the lumen for subsequent dilations by passing a small catheter through the stricture was also developed. This technique offers an option for patients with otherwise untreatable strictures, with the major advantage of visualization from above and below.
