Clinical features of 44 patients with small bowel Crohn's disease.

OBJECTIVES: At present, there are many studies on Crohn's disease of terminal ileum and colon, but few studies on Crohn's disease of small intestine alone. This study aims to analyze the clinical features and therapeutic effect of small bowel in adult patients with Crohn's disease so as to strengthen the diagnosis and treatment for this disease. METHODS: From July 1, 2015 to October 31, 2018, patients with small bowel Crohn's disease at Department of Gastroenterology, Third Xiangya Hospital of Central South University, were enrolled. At the same time, patients' demographics and clinical data were collected. RESULTS: <0.05). Among the most common symptom of abdominal pain (34/44, 77.3%), 11 patients (25.0%) developed complications (eg. intestinal obstruction) during the follow-up, and 66.7% of patients treated with mesalazine had complications. CONCLUSIONS: Patients with ileum account for a large proportion in patients with small bowel Crohn's disease. Stricture is more common in small bowel Crohn's disease. Stricture and longitudinal ulcer are more common under enteroscopy. Crohn's disease activity index is correlated to hemoglobin, red blood cell specific volume, and erythrocyte sedimentation rate. The most common complication is intestinal obstruction. Mesalazine is less effective on small bowel Crohn's disease.
