NCT07701811

Brief Summary

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.

Study Arms (2)

AI-assisted written patient information

EXPERIMENTAL

Participants receive standardized medical treatment plus AI-assisted written patient information that contains the same medical content as the verbal counseling and has been pre-validated by the investigators.

Behavioral: AI-assisted written patient information

Standardized verbal counseling

ACTIVE COMPARATOR

Participants receive standardized medical treatment plus standardized verbal counseling alone.

Behavioral: Standardized verbal counseling

Interventions

Investigator-validated written patient information prepared with AI assistance and provided in addition to standard medical treatment.

AI-assisted written patient information

Standardized verbal counseling regarding medical treatment and lifestyle measures, provided in addition to standard medical treatment.
