Chronic ulcerative colitis

Last edited: 4/15/2026

Overview

Chronic ulcerative colitis is a chronic inflammatory condition affecting the colon and rectum, often leading to complications such as pyoderma gangrenosum and ileal varices post-surgery 12.

Diagnosis

  • Clinical symptoms include bloody diarrhea, abdominal pain, and weight loss.
  • Endoscopic examination with biopsies confirms the diagnosis.
  • Imaging may be used to assess complications like ileal varices 2.
  • Management

  • First-line treatments: Aminosalicylates (e.g., mesalamine) and corticosteroids for moderate to severe disease 1.
  • Adjunctive therapies: Immunomodulators (e.g., azathioprine, 6-mercaptopurine) and biologics (e.g., anti-TNF agents) for refractory cases 1.
  • Control of underlying illness: Essential for managing associated conditions like pyoderma gangrenosum 1.
  • Special Populations

  • Post-surgery complications: Monitor for ileal varices, especially after total proctocolectomy, with potential need for portacaval shunting 2.
  • No specific guidance provided for pregnancy, pediatrics, or elderly populations in the given abstracts.
  • Key Recommendations

  • Manage pyoderma gangrenosum with both local wound care and systemic treatment of underlying chronic ulcerative colitis (Evidence: Moderate) 1.
  • Consider portacaval shunting for recurrent hemorrhage from ileal varices post-total proctocolectomy (Evidence: Weak) 2.
  • Employ a stepwise approach to therapy, starting with aminosalicylates and escalating to corticosteroids, immunomodulators, and biologics as needed for disease control (Evidence: Expert opinion) 1.
