The goal of the consensus initiated by the European Crohn’s and Colitis organisation(ECCO)was to establish the European consensus guidelines for surgical treatment of ulcerative colitis. The consensus covered four parts:the preoperative phase,intraoperative phase,postoperative phase and special situations. This consensus guideline was published in“Journal of Crohn’s and Colitis”and posted on the websites of ECCo in 2015. Interpretation of main points of this consensus was presented in this paper.
