Clinical features of 62 cases of small bowel Crohn's disease
Notice bibliographique
Résumé
Objective To investigate the clinical features of small bowel Crohn's disease(CD).Methods From January 2009 to September 2012,a total of 138 patients diagnosed as CD who underwent examinations of colonoscopy,digestive tract radiography,capsule endoscopy,double-balloon enteroscopy and computed tomography (CT) enterography were enrolled.According to the Montreal Classification criteria,the disease was typed by the age at diagnosis,location of the lesions and behavior of the disease.The clinical symptoms,laboratory examinations,diagnostic methods and recurrence condition were also evaluated.Through the comparison of the clinical features of ileocolonic and colonic CD,the clinical features of small bowel CD were analyzed.Measurement data were analyzed with t-test,analysis of variance or non parametric test.Chi square test was performed for count data.Spearman's correlation analysis was used for correlation analysis and multivariate Logistic regression analysis was used for risk factors screening.Results A total of 62 (44.9％) cases were simple small bowel CD.Fifty-three patients (85.5％) were male,and the mean age at diagnosis was 35.3 years old.The age of 67.7％(42/62) of small bowel CD patients were less than 40 years old when diagnosed.The ratio of stricture in small bowel CD group (35.5％,22/62) was significantly higher than that of ileocolonic (18.8％,6/32) and colonic CD group (13.9％,5/36) (x2=6.594,P=0.037).Jejunal involvement was an independent risk factor for structure in CD (OR=3.481,95％ CI:1.250 to 9.693).The patients with obstructive symptoms as primary symptom in small bowel CD (38.7％,24/62) were more than those with colonic CD (16.7％,6/36) (x2 =5.210,P=0.022).However,patients with diarrhea as primary symptom in small bowel CD (21.0％,13/62) were less than those with ileocolonic (37.5％,12/32) and colonic CD (44.4％,16/36) (x2=6.512,P=0.039).Patients with two or more extraintestinal manifestations in small bowel CD (3.2％,2/62) were also significantly less than those with ileocolonic (15.6％,5/32) and colonic CD (19.4％,7/36) (x2=7.957,P=0.019).The score of CD activity index was generally low,and with no statistical correlation to serum inflammation markers such as C reaction protein.The average time duration between induction of remission and clinical recurrence of small bowel CD ((23.64 ± 17.08) months) was shorter than that of ileocolonic type ((35.07±29.84) months,t=-4.285,P=0.002) and colonic CD ((32.35 ± 28.46) months,t =-3.700,P =0.004).However,there was no significant difference in the rate of clinical recurrence between small bowel CD and ileocolonic,colonic CD.Conclusions Patients with small bowel CD account for a large proportion in patients with CD,especially in males.Stricture is more common in jejunum CD.The time duration between induction of remission and clinical recurrence of small bowel CD is short.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
