Objective  To explore the clinical characteristics of Crohn’s disease (CD) with perianal fistula by analyzing the clinical data of them. Methods  A total of 139 cases of CD with perianal fistula who got treatment from January 2010 to January 2017 in The Affiliated Hospital of Nanjing University of Traditional Chinese Medicine were analyzed retrospectively. Results  The proportion of males and females in 139 patients was about 3.3∶1.0, the age was (28±8) years, and 47.5% of patients had perianal fistula before CD diagnosis. The percents of patients with perianal surgery history and medication history were 64.7% and 74.1%, respectively. The ratio of L3 type (diseased position) was 49.6%. The ratios of inflammatory type (B1 type) and stenotic type (B2 type) of the disease were 51.8% and 41.0%, respectively. The complex perianal fistula accounted for 90.6%, and 31.7% of patients combined analrectal stricture. Symptoms of diarrhea were found in 46.0% of patients and perianal lesions alone in 29.5% of patients; 54.0% of patients combined with abnormal BMI; 64.7% of patients were in the active stage of Crohn’s disease activity index (CDAI) and 94.2 % of patients were in the active period of perianal disease activity index (PDAI). The patients with erythrocyte sedimentation rate (ESR) higher than normal were 53.2%. The results of logistic showed that, age and degree of CDAI were influencing factors for CD with stenosis of perianal fistula. Conclusions  Characteristics of patients with CD combined with perianal fistula include: young, men predominant, high prevalence of ileocolic position involvement, as well as inflammation and stenosis disease behavior. Fistula symptoms often preced the intestinal symptoms and diarrhea is the most common intestinal performance. History of perianal abscess and fistula operation are common. The anorectal stricture are complicated usually. Intestinal inflammation is active. Some patients show abnormal laboratory indicators of inflammation. This suggests that patients with perianal fistula with these clinical features should be alert to the possibility of CD, so as toavoid the consequences of blind surgery. The higher CDAI score and the older the diagnosis age, the higher the risk ofrectal stenosis.
