Evaluation of deep small bowel involvement by double-balloon enteroscopy in Crohn's disease
ABSTRACT Double-balloon enteroscopy (DBE) enables inspection of deep small bowel, and total small bowel examination can be performed by either antegrade or retrograde DBE. The aim of this study was to evaluate ileal involvement, which cannot be achieved using conventional colonoscopy, by DBE in patients with Crohn's disease.
From December 2003 to September 2005, a total of 44 patients with Crohn's disease underwent 53 examinations using DBE.
Forty patients with Crohn's disease, seven women and 33 men, underwent DBE, and the ileum was investigated in 38 patients. There were 25 cases of ileitis, 2 of colitis, and 13 of ileocolitis. Jejunal lesions were found in two and ileal lesions proximal to the terminal ileum were found in 24 patients with Crohn's disease. DBE was superior to radiological study to detect aphthae, erosions, and small ulcers in the ileum. Small bowel stricture was demonstrated in six and nine patients with DBE and small bowel barium study (SBBS), respectively. An additional mucosal finding was demonstrated in one of the eight patients who underwent wireless capsule endoscopy, and one patient had a capsule removed by DBE that had become lodged because of an ileal stricture. One ileal perforation because of overtube balloon pressure occurred in 53 examinations of patients with Crohn's disease (1.9%).
DBE is useful to evaluate small bowel lesions in patients with Crohn's disease; however, special attention should be paid to mesenteric longitudinal ulcers during insertion and the overtube balloon should not be inflated if a clear intestinal view is not possible.

ABSTRACT: Limited information suggests the existence of a high prevalence of hepatitis B (HBV) and C virus (HCV) infection in inflammatory bowel disease (IBD). This knowledge is relevant because the viruses may reactivate under immunosuppressive therapy. The objectives of this study are to assess the prevalence of HBV and HCV infection in IBD, in a nationwide study, and to evaluate associated risk factors. This cross-sectional multicenter study included 2,076 IBD patients, consecutively recruited in 17 Spanish hospitals. Factors related to IBD (severity, invasive procedures, etc.) and to infection (transfusions, drug abuse, etc.) were registered. Independent risk factors for viral infection were evaluated using logistic regression analysis. Present and/or past HBV and HCV infection was found in 9.7% of patients of both ulcerative colitis (UC) and Crohn's disease (CD) (UC: HBsAg 0.8%, anti-HBc 8%, anti-HCV 1.3%; CD: HBsAg 0.6%, anti-HBc 7.1%, anti-HCV 2.3 %). Effective vaccination (anti-HBs, without anti-HBc) was present in 12% of patients. In multivariate analysis, age (odds ratio (OR) 1.04; 95% confidence interval (CI) 1.02-1.06; P=0.000), family history of hepatitis (OR 2.48; 95% CI 1.3-4.74; P=0.006) and moderate-to-severe IBD disease (OR 2.5; 95% CI 1.02-6.15; P=0.046) were significantly related to HBV, whereas transfusions (OR 2.66; 95% CI 1.2-5.87; P=0.015) and antibiotic use (OR 2.66; 95% CI 1.1-6.3; P=0.03) were significantly related to HCV. The significance for transfusions was lost if they were administered after 1991, when HCV markers became mandatory in blood banks. Prevalence of HBV and HCV infection in IBD is similar to that of the general population of reference and lower than that in previously published series. This fact, in addition to the lack of association with invasive procedures, suggests the existence of adequate preventive measures in centers attending to these patients. The low percentage of effective vaccination makes it mandatory to intensify B virus vaccination in IBD.The American Journal of Gastroenterology 02/2009; 104(1):57-63.

ABSTRACT: Endoscopic assessment of the small bowel is difficult because of its long and tortuous anatomy. However, recent developments have greatly improved the insertion depth and diagnostic yield, by means of device-assisted enteroscopy (DAE). Therefore, DAE may be of specific interest in the diagnostic and therapeutic approach of patients with inflammatory bowel disease. It may be of help in the diagnostic assessment of intestinal disease extent and severity and complications, with an impact on the therapeutic management. Moreover, local treatment within the small bowel is also feasible with DAE. This review aims to provide an overview of the currently available literature data on the use of enteroscopy in inflammatory bowel disease, and Crohn's disease in particular.Annals of Gastroenterology 03/2012; 25(1):14-20.
