摘要：The purpose of the present invention is to provide a viscoelastic compositionhaving excellent operability, which is suitable for use in securing the field of view of anendoscope when opaque dark-colored liquid accumulates inside a canal and obstructsthe field of view of the endoscope, the viscoelastic composition securing the field of viewby pushing the liquid aside, and to provide a method for securing the field of view of anendoscope using the viscoelastic composition. The viscoelastic composition for securingthe field of view of an endoscope comprises a substance having viscoelastic propertiesand water, preferably has a hardness of 550 N/m or less, a viscosity (25°C) of 200 to 2,000mPa·s, and a loss tangent of 0.6 or less, and more preferably has an electricalconductivity of 250 µS/cm or less. The method for securing the field of view of anendoscope comprises feeding the viscoelastic composition from a proximal part of theendoscope, through a channel, into a distal part of the endoscope.
