Claim:
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 consisting essentially of hyaluronic acid or a medically acceptable salt thereof and chondroitin sulfate or a medically acceptable salt thereof wherein the medical composition 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., chondroitin sulfate or a medically acceptable salt thereof.
