The analysis of Montreal classification for 102 patients with Crohn's disease / 中华消化杂志

ABSTRACT

Objective To analysis the features of Montreal classification,serum markers,treatment and prognosis of Chinese patients with Crohn's disease(CD),and to estimate the relationships between clinical classification and anti-sarccharomyces cerevisiae antibody(ASCA),treatment and prognosis.Methods A retrospective study of 102 consecutive definite CD eases were performed and all subjects were classified into subtypes according to Montreal classification.The results of ASCA,extra-intestinal manifestation,treatment and disease behavior at follow-up were recorded and compared among different subtypes.Results The A2 subtype(52.9%)was dominated in Chinese CD patients.Ileocolon location(40.2%)and stricture lesion (53.9%)were common.The complication rate was dependent on disease course(P＜0.05),and intestinal fistula was associated with disease location(P=0.074).B1 subtype had higher progressive rate than B2 subtype(P=0.018).ASCA was not associated with disease loeation,disease behavior,treatment and disease progression(P＞0.05).Conclusions Crohn's disease mainly attack young people with male predominance.Early-onset CD patients have higher ASCA positive rate and disease progressive rate.The disease behavior progresses associated with disease course,and the rate of complication and the increase of surgery.The penetrating behavior is the main cause for surgery.Montreal classification is useful to predict the disease course,the need for surgery as well as the prognosis.
