Study Details

Study Description

Brief Summary

Using the analysis of group velocity for a screening application and then higher order analysis based on the elastic and viscious components of the shear modulus may allow discrimination between extent of tumor invasion through the esophageal wall if appropriately correlated with pathological findings.

Condition or Disease Intervention/Treatment Phase
  • Device: General Electric LOGIQ E9 ultrasound system
N/A

Detailed Description

Use of ultrasound-based vibrometry in this setting would allow for a relatively simple study and translation of clinical practice, as the same devices are already used in this setting, and operators have familiarity with the equipment. Incorporating another additional method to generate contrast for determining malignant tissue from normal based on biomechanical properties with the same probe would have benefit as an additional diagnostic modality.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Ultrasound

Device: General Electric LOGIQ E9 ultrasound system
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.
