OUTCOME OF PERIANAL FISTULAS IN CROHNS-DISEASE - VALUE OF HUGHES PATHOGENIC CLASSIFICATION

Applying the Hughes' pathogenic classification of anoperineal lesions of Crohn's disease, this study was conducted to find out its possible prognostic value in perianal fistulas. Thirty-eight patients with ano- perianal fistulas were included; primary specific lesions (condyloma, cavitating ulcer, fissure) were found in 22 patients (group 1) and wer e absent in the other 16 patients (group 2). Patients of group 1 under went more abdominal surgical interventions (G 1: 68 %; G 2: 31 % - P = 0.05), as well as proctological interventions (G 1: 2.95 operations/p atient vs 1.35 in G 2 - P = 0.01). Perfect continence was recorded ult imately in 31.8 % patients of G 1 compared to 62.5 % of G 2. This stud y shows the very poor prognosis of ano-perianal fistulas in Crohn's di sease.
