The current invention describes methods of transesophageal access to the neck and thorax to perform surgical interventions on structures outside the esophagus in both the cervical and the thoracic cavity. It describes a liner device made of a complete or partial tubular structure, or a flat plate, the liner having means to facilitate creation of a side opening, which may include a valve. The liner with its side opening form a port structure inside the esophageal lumen. The port structure allows elongated surgical devices to pass through a perforation across the full thickness of the esophageal wall to outside location, in a controlled way. The elongated surgical devices can be diagnostic scopes, therapeutic scopes, manual elongated surgical devices, robotic arms or the like. After being deployed outside the esophagus, the surgical devices can access structures outside the esophagus, in the neck and thorax in 360 degrees of freedom around the esophageal circumference. These structures can be bony, cartilaginous, spinal, vascular, soft tissue, deep tissues, lymph nodal, cardiac, pulmonary, tracheal, nervous, muscular or diaphragmatic, skin and subcutaneous tissues of the neck, skin and subcutaneous tissues of the anterior chest wall, skin and subcutaneous tissues of the skin of the back, and skin and layers of the breast.
