Low adherence to colonoscopy in the screening of first-degree relatives of patients with colorectal cancer.

Background: Colonoscopy is one of the methods of choice for screening relatives of patients with colorectal cancer.

Objective: To evaluate the rate of adherence to colonoscopy in first-degree relatives of patients with colorectal cancer and describe the lesions found.

Methods: A prospective, cross-sectional, multicentre, nationwide study was conducted.

MRI evaluation of inflammatory activity in Crohn's disease.

Objective: We wanted to assess the capability of MRI to quantitatively evaluate the therapeutic response to Crohn's disease (CD) relapse.

Subjects And Methods: Twenty patients with histologically proven CD were prospectively evaluated with MRI and ileocolonoscopy over a 2-year period. The MRI protocol included axial and coronal T2-weighted and contrast-enhanced T1-weighted sequences.

[Colonoscopic follow-up of patients undergoing curative resection of colorectal cancer].

Aim: To investigate the role of colonoscopy in the follow-up of patients undergoing curative resection of colorectal cancer.

Material And Methods: A prospective study was performed of 102 patients with colorectal cancer who underwent surgery with curative intention. Postoperative colonoscopic follow-up was a minimum of 5 years.

[Treatment with omeprazole, clarithromycin and amoxicillin over 6 days in patients with Helicobacter pylori-infected duodenal ulcer].

Objective: To investigate the eradication rate of Helicobacter pylori with omeprazole, amoxicillin and clarithromycin during 6 days in patients with duodenal ulcer. To compare the reliability of the analysis of the eradication with urea-13C breath test performed one month and 3 months after therapy. To evaluate the one-year reinfection rate.

[Magnetic resonance cholangiopancreatography (MRCP) versus endoscopic retrograde cholangiopancreatography (ERCP): diagnostic usefulness].

Magnetic resonance cholangiopancreatography (MRCP) is a new noninvasive technique to examine the biliopancreatic tract that have a high diagnostic accuracy. Thus it becomes an appealing modality that can avoid invasive approaches. The purpose of this study was to evaluate the sensitivity and specificity of MRCP in comparison to endoscopic retrograde cholangiopancreatography (ERCP).
