[Mucosal healling: a realistic aim or marketing myth?].

The classical aim of the treatment of ulcerative colitis is to induce and maintain remission. However, this aim has not been shown to prevent long-term complications. Current treatment goals attempt to prevent complications. In some studies, healing of the intestinal mucosa has been shown to improve long-term outcomes. In ulcerative colitis, mucosal healing reduces recurrence, the risk of colorectal cancer and the need for surgery, and improves patients' quality of life. The drugs for which there is greatest evidence of their efficacy in inducing and maintaining mucosal healing are salicylates and biological agents. In the near future, endoscopic monitoring may be required to evaluate response to the treatment and decisions may have to be taken according to the persistence or disappearance of these lesions.
