About this trial
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.

Treatment groups
Trial outcomes
Primary outcomes
Complete treatment adherence at Day 14
Complete treatment adherence at Day 14, defined as a total adherence score of at least 5 out of 6 predefined treatment-behavior items: regular topical medication use, correct application to the target area, regular stool softener or fiber support, achievement of the water intake target, regular warm sitz bath or warm water application, and avoidance of excessive straining.
Secondary outcomes
Pain during defecation at Day 7
Pain during defecation assessed using a 0 to 10 Visual Analog Scale, where 0 indicates no pain and 10 indicates the worst imaginable pain; higher scores indicate worse pain.
Pain during defecation at Day 14
Pain during defecation assessed using a 0 to 10 Visual Analog Scale, where 0 indicates no pain and 10 indicates the worst imaginable pain; higher scores indicate worse pain.
Pain during defecation at Week 6
Pain during defecation assessed using a 0 to 10 Visual Analog Scale, where 0 indicates no pain and 10 indicates the worst imaginable pain; higher scores indicate worse pain.
Patient Global Impression of Change at Day 7
Patient Global Impression of Change assessed on a 7-category ordinal scale: very much improved, much improved, a little improved, unchanged, a little worse, much worse, and very much worse.
