Radiologic vs. Endoscopic Evaluation of the Conduit After Esophageal Resection: a Prospective, Blinded, Intraindividual Controlled Diagnostic Study.
This prospective, blinded, intraindividual controlled study will be conducted with patients
with transthoracic esophagectomy due to esophageal cancer. A radiographic contrast study
will be performed prior to endoscopy at the 5th to 7th postoperative day. The investigators
will not be aware of the results of the corresponding examination. Sensitivity, specificity
and feasibility of the radiologic and endoscopic evaluation of the esophageal substitute
will be compared.
