The purpose of this study is to determine if, after an Ivor Lewis esophagectomy (the surgical removal of a portion of the stomach and esophagus, with re-attachment of the remaining ends) there is an association between the level of oxygen at the site where the esophagus is re-attached to the stomach (measured using a wireless oxygen sensor) and the incidence of a disruption at the site of the attachment after the surgery (called a “leak”).
Leaks occur when the site of the attachment between the remaining esophageal and stomach tissue does not heal properly. Patients who have a leak are at risk of other complications, such as pneumonia or blood clots. Poor oxygenation of tissue may raise the risk of a leak by impairing healing. The use of a sensor to measure tissue oxygen levels during the operation may help guide the surgeon in finding the safest location to re-attach the esophagus to the stomach, which could help reduce the risk of a leak.
