Lower Lugol's Solution Concentration on Reducing the Adverse Symptoms of Chromoendoscopy With Iodine Staining

2017-06-08 20:38:22 | BioPortfolio


This study was to test an appropriate concentration of Lugol's solution which can reduce the mucosal irritation and provide high image quality to ensure endoscopy examination by a randomized blinded controlled trial.


It is widely accepted that chromoendoscopy using Lugol's solution is effective for the detection of early esophageal squamous neoplasia. However, this modality may cause severe chest pain and discomfort owing to mucosal irritation. The conventional concentration of Lugol's solution is in the range of 1.2% to 2.5% . Image quality can be guaranteed with this range of Lugol's solution. However, lead to retrosternal pain and discomfort, and can even induce erosion or ulceration in the esophagus and stomach. This study was to test whether a lower concentration of Lugol's solution, which has minimal mucosal irritation, can provide satisfied image quality by a randomized blinded controlled trial.

Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g NaCl in 100 ml purified water).

The pressure required to prevent the passage of solvent through a semipermeable membrane that separates a pure solvent from a solution of the solvent and solute or that separates different concentrations of a solution. It is proportional to the osmolality of the solution.
