The Mexican consensus on the diagnosis and treatment of ulcerative colitis.

The guidelines presented herein are an updated version of the recommendations published in 2007. Since then, there has been a rapid advance in the knowledge about the pathophysiology of ulcerative colitis and its therapeutic options. New drugs have been approved, novel targeted therapies have emerged, and new strategies have been developed to improve the previously available approaches to the disease. The aim of the present consensus is to promote the current knowledge of and Mexican perspective on the epidemiology, diagnosis, and medical and surgical treatment of chronic idiopathic ulcerative colitis. The final vote on the statements and their ultimate modifications were carried out at the consensus working group meeting. Evidence was evaluated through the GRADE classification.
