Montgomery Salivary Bypass Tube vs Self-Expandable Metal Stents for the treatment of esophageal strictures after total laryngectomy. a crossover study

Objectives. Dysphagia affects 16 per cent of patients undergoing total laryngectomy, of these, a third is due to pharyngoesophageal stenosis. Currently, the treatment is cyclic dilation of the stricture and Montgomery Salivary Bypass Tube - MSBT - application. The aim of this study is to assess whether using Self-Expandable Metal Stent - SEMS - may give better results after a non-durable response to repeated dilatation and application of MSBT Conclusion. In patients who are already undergoing cyclic dilations and application of MSBT switching to SEMS is not beneficial. Furthermore, MSBT has a significantly shorter implant procedure, does not expose the patient to X rays, and, in the absence of complications, has a longer duration before removal.
