M. Pescatori et al., MANAGEMENT OF PERIANAL CROHNS-DISEASE - RESULTS OF A MULTICENTER STUDY IN ITALY, Diseases of the colon & rectum, 38(2), 1995, pp. 121-124
PURPOSE: Management of perianal Crohn's disease is still controversial
, and reports on large series are very few in the literature. The aim
of this multicenter study was to investigate the outcome of both medic
al and surgical treatment in 225 patients. METHODS: Patients cared for
at different institutions were followed up for a median of six years.
Most of them had either anal fistula or an abscess (86 percent and 43
percent, respectively), but fissures were also present in 26 percent
of the cases. Diarrhea and anal pain were the most common symptoms. An
al lesions preceded the onset of intestinal symptoms in 19 percent of
cases. RESULTS: Medical treatment was curative only in 21 of 123 patie
nts. Overall, medical and surgical treatment either cured or improved
62 percent of the cases. Fifty percent had an intestinal resection. Ab
scess drainage and fistulotomy were the most common anal surgeries. Re
ctovaginal fistulas (n = 30) required intestinal surgery in 36 percent
and anal surgery in 20 percent of the cases, 50 percent with good res
ults. Of 166 patients who had anal surgery, 97 (58 percent) had a posi
tive outcome. Recurrence of anal disease requiring further surgery occ
urred in 24.5 percent of the cases. CONCLUSIONS: Limited surgeries see
m to achieve satisfactory results in more than one-half of the patient
s affected by perianal Crohn's lesions, whereas medical treatment alon
e is curative in a small portion of them.
