Successful use of biliary accessories in antegrade dilation of complex upper esophageal stricture due to chemoradiation and surgery

Endoscopic management of complete or near complete upper esophageal strictures is challenging. Current methods such as retrograde esophageal access are high risk and may require additional abdominal surgery. A biliary cannulation technique with a 0.035 inch guidewire was utilized to obtain antegrade esophageal access in a patient with near complete high esophageal stricture due to chemo radiation and surgery for head and neck cancer. Biliary accessories including bougie and balloon dilators were used for the initial dilation of the esophageal stricture, followed by the traditional approach of stricture dilation using over-the-wire dilators. The procedure was successfully performed in a patient with near complete upper esophageal stricture due to chemo radiation and surgery for recurrent laryngeal cancer. The dysphagia of this patient was resolved following serial esophageal dilations and his esophageal stricture was wide open on the last upper endoscopy. Biliary accessories can be safely used for obtaining antegrade esophageal access and dilation of near complete upper esophageal strictures. This approach should be considered in patients with complex esophageal strictures, especially after chemo radiation or surgery for head and neck cancer and prior to seeking other more complex alternatives involving retrograde esophageal access.
