Medical composition for protuberance of epithelium

Abstract

A medical composition for protuberance of epithelium, which comprises a solution comprising a polysaccharide or a medically acceptable salt thereof, wherein the solution has a viscosity of: (1) from 50 to 500 mPa·s at a shear rate of from 7.7 to 10.0 s −1 ; (2) from 45 to 300 mPa·s at a shear rate of from 19.2 to 20.0 s −1 ; and (3) from 40 to 200 mPa·s at a shear rate of from 38.3 to 40.0 s −1 , when measured using a rotational viscometer at 25° C., and a syringe filled with the medical composition.

1 - 16 . (canceled) 
     
     
         17 . A method for resecting epithelium, which comprises:
 administering an effective amount of a medical composition to under epithelium to thereby obtain protuberance of the epithelium; and   resecting the protuberance,   wherein the medical composition comprises a solution comprising sodium hyaluronate having a weight average molecular weight of from 880,000 to 920,000 and its concentration in the solution is 0.4% (w/v).   
     
     
         18 . The method according to  claim 17 , wherein the epithelium is mucosa. 
     
     
         19 . The method according to  claim 18 , wherein the mucosa is digestive organ mucosa. 
     
     
         20 . The method according to  claim 17 , which is used for a mucosal resection. 
     
     
         21 . The method according to  claim 17 , wherein the composition is administered using a syringe.
