1. An endoscopic guide tube comprising:

  • a semi-flexible hollow cylinder having a distal and proximal end, the cylinder to be inserted into a body cavity to guide the distal end portion of the flexible tube of an endoscope into the body cavity;

    a first expandable balloon affixed peripherally about the semi-flexible hollow cylinder and positioned on the hollow cylinder so as to occlude the esophageal lumen upon inflation of the first expandable balloon;

    a second and third expandable balloons affixed peripherally about the flexible hollow cylinder adjacent to the distal end of the semi-flexible hollow cylinder, the second and third expandable balloons securing the semi-flexible hollow cylinder upon inflation of the balloons thereby providing direct access to the peritoneum and allowing the insertion, manipulation and removal of instruments during a procedure;

    a bite block adjacent to the proximal end of the semi-flexible hollow cylinder; and

    a valve at the proximal end of the flexible hollow cylinder, the valve sealing the lumen of the cylinder from the external environment thereby preventing leaking or insufflation and allowing access to the flexible hollow cylinder for insertion, removal and manipulation of instruments during a procedure.
