**2.2 Ulcerative colitis**

UC is a chronic inflammatory condition characterized by continuous mucosal inflammation of the colon and rectum.

Nowadays, surgery is required in a limited number of patients with UC, either in an elective or in an emergency setting.

In patients with UC and indication for surgery, RPC is widely considered the gold standard surgical procedure. However, TAC-IRA is justified for some particular cases.

Emergent colectomy in UC is indicated in acute severe UC, not responding to medical therapy, or when complications occur such as severe bleeding, toxic megacolon, and colon perforation [6].
