About

The aims of the present study:

  1. To investigate the diagnosing value of optical enhancement technology for early esophageal squamous neoplasia.
  2. To assess the detection rate of early esophageal squamous neoplasia by virtual chromoendoscopy with optical enhancement technology .

Full description

Detection and differentiation of esophageal squamous neoplasia (ESN) are of value in improving patient outcomes.Optical enhancement technology can serves in the diagnosis of GI neoplasia. However, its performance in ESN has not yet been reported.The aims of the present study is:

  1. To investigate the diagnosing value of optical enhancement technology for early esophageal squamous neoplasia.
  2. To assess the detection rate of early esophageal squamous neoplasia by virtual chromoendoscopy with optical enhancement technology .

    • First degree relatives have a history of esophageal squamous cell carcinoma ;
    • Previous history of esophageal lesions ( esophageal squamous neoplasia );
    • The patients having a history of cancer;
    • A long history of smoking ;

  2. Patients aged between 40 to 74 years old.

Exclusion criteria

  1. Having advanced esophageal carcinoma;
  2. After esophageal surgery or endoscopic treatment ;
  3. Known esophageal radiotherapy or chemotherapy ;
  4. Esophageal stenosis;
  5. Acute bleeding;
  6. A known allergy to iodine;
  7. Coagulopathy (prothrombin time <50% of control, partial thromboplastin time >50 seconds);

Trial design

360 participants in 1 patient group

Optical enhancement technology examination
Description:
After routine examination by white-light endoscopy,the imaging mode will be switched to optical enhancement.Suspicious area will be recorded in detail. Then all enrolled patients will have their esophagus sprayed with iodine solution. Suspicious area will be also recorded in detail.After that biopsy specimens will be obtained respectively by forceps from each suspicious lesion recorded for histologic diagnosis.
