Use of Intra-Operative Shear Wave Ultrasound Vibrometry for Characterization of Esophageal Malignant Tumors

Patients will be brought to the operating room in line with standard clinical practice and after esophageal exposure, but before surgical mobilization of the esophagus, shear wave vibrometry and B-mode imaging will be performed after esophageal distension with a fluid filled balloon intra-operatively.
