This is a randomized, single-center clinical trial that will compare the efficacy of two substances used in the submucosal cushion formation stage of endoscopic submucosal resections of early esophageal malignant neoplasms. Such substances are hyaluronic acid in the form of TS-905 Blue Eyeₒ and hydroxyethylamide (Voluven®).
1. Design of the study: This is a randomized clinical trial in a single center. The lesions will be randomized into three blocks based on the diameter of the largest axis (less than 3 cm, between 3 - 5 cm and greater than 5 cm). 2. Selection of patients: The population studied will be patients with early esophageal neoplasia diagnosed and/or referred for submucosal endoscopic dissection at the São Paulo Cancer Institute (ICESP), University of São Paulo. 3. Evaluation of effectiveness and definitions: Effectiveness will be measured from the degree of usefulness. The degree of utility will be determined from two variables: obtaining or not a complete block resection and additional number of submucosal injections performed during endoscopic dissection. The solution that results in a complete block resection with a number of additional injections of 0 (excellent utility degree) or 1 (good utility degree) will be considered effective.

The resection will be performed in three stages using hydroxyethylamide : delimitation, incision and dissection. Initially we will inject the hydroxyethylamide and examine the delimitation of the lesion. With Knife itself, using soft or Forced coagulation current, we will circumvent the limits of the lesion with punctual coagulations 5 mm away from it.
