AI-Assisted Written Information in Chronic Anal Fissure

This single-center, prospective, 1:1 randomized, parallel-group controlled superiority trial compares standard verbal counseling with AI-assisted written patient information in adults with primary chronic anal fissure receiving initial medical/conservative treatment. The primary objective is to determine whether AI-assisted written information improves complete treatment adherence at day 14. Secondary objectives include pain and discomfort outcomes, Patient Global Impression of Change, HEMO-FISS-QoL change, stool form change, additional healthcare visits, transition to interventional treatment, and patient satisfaction.
