  • Salivary Bypass Tube
  • Hood Salivary Bypass Tubes are designed to control salivary leakage from the pharyngocutaneous fistula after total laryngectomy, and to stent the cervical esophagus following dilation of a stricture.

    Bypass tubes are frequently used in patients with poor wound healing due to systemic problems (e.g., poor nutritional status, metabolic disorders) or regional factors (e.g., post irradiation changes, recurrent or persistent neoplasm, and chronic infection). Because of these host factors, placement of the tubes may be associated with pressure necrosis of local tissues. Therefore, patients with these tubes in place should be monitored carefully by x-ray and direct inspection if localized pressure necrosis of regional soft tissue is suspected.

    The tubes are designed to fit securely in the superior esophagus and hypopharynx. However, it is possible for a loose-fitting tube to be displaced distally into the esophagus. This may be prevented by securing the tube to an indwelling gastric tube.

    The Hood Intended Use and Instruction Manual, which is supplied with each product, provides detailed information on insertion technique, sterilization, and postoperative care.
     
 
  • Esophageal Reconstruction Tube
  • The Adjustable Esophageal Reconstruction Tube is a modification of the original design of the Hood Esophageal Reconstruction Tube. It is used in temporary reconstruction and stenting of the cervical esophagus.

    The tube is used after the first-stage operation to relieve profuse salivary leakage by way of the pharyngostoma. It maintains a wide patent pharyngostoma and creates a trough between the pharyngostoma and the esophagostoma to facilitate the second-stage procedure.

    The funnel shaped superior end conforms to the hypopharynx and has been redesigned to adapt to the anatomy of the esophagus at the upper post cricoid level. The bulbous protrusions are adjustable allowing flexibility in adjustment of the tube position to prevent displacement without suturing the tube.

    The Hood Intended Use and Instruction Manual, which is supplied with each product, provides detailed information on insertion technique, sterilization, and postoperative care.
     
 
  • Esophageal Stent
  • The Hood Esophageal Stent aids in management of esophageal obstructions and fistulas in irresectable carcinoma and post-radiation stenosis. Studies report quality of palliation in dysphagia equal to neodymium YAG laser therapy at substantially lower costs. Designed for endoscopic placement, the Esophageal Stent saves expense through an outpatient procedure.

    The Esophageal Stent permits passage of food and saliva and is made of soft, conforming, non-irritating, and implant-grade silicone. A tapered flange minimizes erosion and maintains patency of the esophagus with minimal migration.

    The Hood Intended Use and Instruction Manual, which is supplied with each product, provides detailed information on insertion technique, sterilization, and postoperative care.
